Operator:           Good day everyone and welcome to the QLogic Corporation
                    announcement. Today's call is being recorded.

                    At this time for opening remarks and introductions, I would
                    like to turn the call over to Mr. Tony Massetti, Senior Vice
                    President and Chief Financial Officer. Please go ahead, sir.

Tony:

                    Thank you operator.

                    Good afternoon and welcome to QLogic's conference call. I'm
                    Tony Massetti, Senior Vice President and Chief Financial
                    Officer, and with me is H.K. Desai, CEO and President. By
                    now all of you should have seen our press release announcing
                    a definitive agreement to acquire PathScale, Inc. In
                    reviewing how this transaction will impact our operating
                    model, some of the comments today will include
                    forward-looking statements regarding future events and / or
                    projections of the financial performance of the Company
                    based on our current expectations. These comments contain
                    significant risks and uncertainties that could cause our
                    actual results to differ materially from those expressed in
                    these forward-looking statements. We refer you to the
                    documents that QLogic files with the SEC, specifically our
                    most recent Forms 10-K and 10-Qs. These documents identify
                    important risk factors that could cause our actual results
                    to differ materially from expectations. We do not intend to
                    update any of the information contained in any
                    forward-looking statements that we make today.

H.K.:

                    Thanks Tony

                    Thank you for joining us today as we announce the signing of
                    a definitive agreement to acquire privately-held PathScale.
                    We will pay approximately $109 million in cash and assume
                    the outstanding unvested stock options of PathScale.

                    As we have indicated in the past, a major component in our
                    growth strategy is to seek new opportunities in our existing
                    markets and to enter high growth markets through the
                    development and/or acquisition of technology. Today's
                    announcement regarding the agreement to acquire PathScale is
                    aligned with our strategy.

                    Similar to our recent acquisition of Troika Networks, the
                    acquisition of PathScale adds new and unique technology to
                    QLogic's expanding portfolio of solutions. An exciting
                    aspect of this acquisition is that it provides QLogic entry
                    into the rapidly expanding System Area Network fabric
                    market.

                    The technology for the emerging System Area Network fabric
                    market is InfiniBand. InfiniBand is a high-performance,
                    low-latency, switched fabric interconnect. The first
                    InfiniBand standard was approved in 2001. Over the past 5
                    years, InfiniBand has slowly gained acceptance in the
                    High-



                    Performance Computing, or HPC, market as the low-latency
                    server interconnect standard of the future.

                    The InfiniBand architecture is an industry standard that
                    defines a high-speed switched fabric designed to connect
                    processor nodes to form a System Area Network fabric. The
                    InfiniBand architecture is different from the conventional,
                    local transaction-based I/O model in that it uses a remote
                    message-passing model across channels. The architecture is
                    independent of the host operating system and the processor
                    platform.

                    InfiniBand's System Area Network fabric components are very
                    similar to the Fibre Channel-based Storage Area Network
                    fabric components. Host Channel Adapters, or HCAs, provide a
                    server to server interconnect function which is similar to
                    the server to storage interconnect that Fiber Channel Host
                    Bus Adapters, or HBAs, provide. Also, similar to a Fibre
                    Channel switched fabric, InfiniBand switches provide a
                    switched fabric capability for server to server
                    communications.

                    Currently, InfiniBand implementations are prominent in high-
                    performance computing environments. In a number of these
                    environments, users have chosen to replace more expensive,
                    monolithic servers with large clusters of inexpensive
                    rackmount servers running Linux and connected with an
                    InfiniBand Systems Area Network fabric. Applications include
                    space exploration, weather forecasting, national security,
                    biotechnology, oil and gas and many other computationally
                    intensive applications where high-bandwidth and low-latency
                    are key requirements. In addition to the rackmount server
                    clusters, several InfiniBand blade server designs have also
                    been announced by major OEMs, accelerating the deployment of
                    dense computing.

                    While current deployments of InfiniBand are geared towards
                    high-performance computing environments, InfiniBand also has
                    a potential to penetrate the enterprise, data center
                    environment. The high-performance and low-latency
                    characteristics of InfiniBand combined with low-cost
                    rackmount and blade server technologies provide a very
                    attractive platform for clustered database applications. The
                    success of InfiniBand in the enterprise data center
                    significantly expands the market potential for this
                    technology.



                    There are only a handful of analysts tracking the System
                    Area Network fabric interconnect market today. However, in a
                    recent InfiniBand workshop, data was provided that showed
                    over one million InfiniBand ports have been deployed as of
                    the end of 2005. Based on this data, and input we have
                    received from analysts, OEMs and end-users, we estimate that
                    the System Area Network fabric market for InfiniBand could
                    reach approximately $400 million by 2009.

                    The target customer base for InfiniBand is the same set of
                    major server OEMs and channel distributors that QLogic
                    serves today. Consequently, we will be able to leverage our
                    current go-to-market model with this new opportunity.

                    PathScale entered the InfiniBand market in 2001. Founded by
                    a team of leading computer system industry veterans,
                    PathScale focused initially on Linux-based environments
                    using AMD processors and hyper-transport bus architecture.
                    Utilizing their vast experience in the HPC market, PathScale
                    developed the InfiniPath HCA technology. This unique HCA
                    architecture greatly improves application performance and
                    cluster utilization for HPC and clustered database
                    environments. To date, PathScale has secured a number of
                    design wins at leading OEMs. These design wins should result
                    in revenue shipments in the second half of fiscal year 2007.

                    We believe that the products developed by the PathScale
                    team, combined with QLogic's industry experience, customer
                    relationships and operational expertise, can achieve
                    industry leadership as this market continues to grow.

                    This acquisition demonstrates our commitment to entering
                    new, high-growth markets that enhance our ability to achieve
                    accelerated growth.

                    I would now like to turn the call back to Tony Massetti for
                    the financial discussion. Tony.............

Tony:

                    Thank you HK.

                    I now want to discuss our expectations for how our non-GAAP
                    operating model will change after this transaction closes.



                    We anticipate our gross margin percentage will not change as
                    a result of this transaction. Consistent with our previous
                    guidance, we expect our gross margin in the next 12 to 18
                    months to be over 65% depending on product mix.

                    We anticipate our operating expenses as a percentage of
                    revenue will increase slightly in the near term.

                    For the first nine months of fiscal year 2006, we reported
                    engineering expenses from continuing operations of 17.7% of
                    revenue, consistent with our targeted range of 16% to 19%.
                    Going forward, we expect engineering expenses will range
                    from 17% to 20% of revenue.

                    For the first nine months of fiscal year 2006, we reported
                    sales and marketing expenses from continuing operations of
                    12.9% of revenue, consistent with our targeted range of 11%
                    to 14%. Going forward, we expect no change in the targeted
                    sales and marketing expense range of 11% to 14% of revenue.

                    For the first nine months of fiscal year 2006, we reported
                    G&A expenses from continuing operations of 3.6% of revenue,
                    consistent with our targeted range of 3% to 4%. Going
                    forward, we expect no change in the targeted G&A expense
                    range of 3% to 4% of revenue.

                    With these gross margin and operating expense assumptions,
                    we continue to target operating margin at approximately 35%.
                    We are comfortable with the First Call consensus of $1.66
                    per diluted share for fiscal year 2007.

                    We expect this transaction to close in early April. We will
                    provide additional details during our fourth quarter and
                    year end earnings conference call in early May.

                    Thank you operator we will now take questions.

Operator:           If you would like to ask a question, you can signal by
                    pressing the star key followed by the digit one on your
                    touch-tone telephone. If you are doing it on a speaker
                    phone, please make sure your mute function is turned off to
                    allow your signal to reach our equipment. Once again, please
                    press star one if you would like to ask a question. We'll
                    take as many questions as time permits and proceed in the
                    order that you signal.



                    We'll go first to Harsh Kumar with Morgan Keegan.

Harsh Kumar:        Hi. Let me just make something clear, Did I hear you
                    correctly you are referencing '07 street numbers, is that
                    correct?

Tony Massetti:      What we said, Harsh, is we're comfortable at this point with
                    the first call consensus of $1.66 per diluted share for
                    fiscal '07.

Harsh Kumar:        Got it. That's helpful. So, I guess this is a pre-revenue
                    company, what can you tell us a little bit about the
                    product, HK? You talked about HCA and then you talked about
                    the InfiniBand switches, what does this company make
                    specifically and maybe we'll start there?

HK Desai:           OK. So this is the Pathscale HCA host channel adapter for
                    the InfiniBand technology and currently the technology is
                    more popular in the HPC market, High Performance Computing,
                    and I think the key, fortunately for us, going forward
                    someday if you can expand into the enterprise data center or
                    the database application. So, I think we are really
                    targeting this technology for the future, see if you can
                    drive the enterprise data then we have good potential for
                    this market.

Harsh Kumar:        And H.K., I was reading up on a technology called, "VFrame"
                    by Cisco, how does this compare to VFrame and how does - how
                    do the two interact?

Rick Franz:         VFrame is a framework, VFrame is a technology that is
                    dependent upon software that Cisco provides around an
                    InfiniBand infrastructure. This, meaning the PathScale HCA
                    would work within the VFrame infrastructure.

Harsh Kumar:        OK. So, it's not a competitor at all?



HK Desai:           No, it's not, because - what you do is like - There are two
                    product lines for this market switch and HCA, These two
                    product lines are just like Fibre Channel HBA, and Switch in
                    the Fibre Channel Market like I said in my script, There are
                    HCAs and there are switches and we are focusing on the HCA
                    markets, so Cisco or anybody can be our customer.

Harsh Kumar:        Got you. I'll turn it over to somebody else and come back
                    later.

Operator:           Thank you. We'll go next to Shebly Seyrafi with Kaufman
                    Brothers.

Shebly Seyrafi:     Yes. Thank you. Just some basic questions and then some more
                    interesting ones. The basic questions, are, what's the
                    current head count at PathScale and what kind of expense per
                    quarter do they currently occur? And then I have some
                    others.

HK Desai:           So, let me handle the first one and Tony can answer the
                    second one. The first one is like, we don't want to talk
                    about the head count, or any of those things until the time
                    when the transaction is closed. We will not give this
                    information out - We want to give out the information no
                    additional information until the transaction is closed.

Shebly Seyrafi:     OK.

Tony Massetti:      And Shebly, the effect to the operating model, we talked
                    about in terms of full year, fiscal '07. So we said, "No
                    change to gross margins." And the only changes to the
                    expense structure would be just a point increase in our E to
                    Rs in engineering expense. So, we've moved the range which
                    was 16 to 19 percent, to 17 to 20 percent for full year
                    fiscal '07. And, then that just falls through to the 35
                    percent operating margin that we talked about. And, you
                    know, we've been targeting 35 percent operating margin for
                    some time. So, that is consistent.



Shebly Seyrafi:     OK. What kind of revenue target do you have in the second
                    half of '07? And in 2008? I'll just give you the other one.
                    How many of your top OEMs are likely to use PathScale's
                    InfiniBand technology?

HK Desai:           We don't want to give you revenue information, I think it's
                    too early for us to really provide this, because, you know,
                    OEM design wins are not always revenue. like I said in my
                    script, there's some design wins with the OEMs, they also
                    have channel business,. The key area is going to be the
                    second half of '07 we expect some revenue then. I mean, it's
                    a really not our place to project the revenue plus we don't
                    want to give any guidance right now because OEM designs are
                    dependent on the time to market for those wins so I think
                    it's too early for us to talk about that.

Shebly Seyrafi:     Thank you.

Operator:           Thank you. We'll move next to Clay Sumner with FBR.

Clay Sumner:        Thanks very much. My understanding of, well is it (Melanox's
                    HCAs are designed to be used in primarily PCIX or PCI
                    express slots, while Pathscale designs are a motherboard
                    solution or a card in an HTX slot? Is that primarily the
                    difference between the respective HCA products?

HK Desai:           Well, currently that's correct. The Pathscale is focusing on
                    the hypertransport interface currently.

Clay Sumner:        And, would it be an easy thing to do, to go to (PCI express)
                    slot compatibility?

Tony Massetti:      Yes.

Clay Sumner:        Can you say roughly what percentage of Linux clusters
                    shipping, maybe in recent quarters, are connected through
                    HCX slots versus (PCI express)?



Tony Massetti:      I don't think we have that.

HK Desai:           No.

Clay Sumner:        OK. I would assume the vase majority have PCI express at
                    this point?

HK Desai:           If you look at the technology or if you look at our product,
                    I mean, it started with the multi core strategy, If you
                    think of the hypertransport interface, there is no issue for
                    them to be going forward to PCI Express,

Clay Sumner:        OK and last one from me. If you could just say roughly what
                    percent, maybe looking at their design win activity, what
                    percent of that design win activity is for motherboard
                    solutions versus card slot solutions?

HK Desai:           I don't think we are ready to talk about that now.

Clay Sumner:        OK. Thank you.

Operator:           We'll move next to Douglas Whitman with Whitman Capital.

Douglas Whitman:    Just wanted make sure, Tony, that I was understanding.
                    Basically, you are saying your margins are not going to
                    change and your EPS estimates are not going to change. It
                    seems like you're absorbing some additional expense and
                    you're loosing the interest income for the 100 million. So,
                    if I'm understanding correctly, is this basically the
                    business - the revenues are running on the high end of
                    expectation, and I am trying to get to how the EPS number
                    doesn't change here.



Tony Massetti:      Sure, Doug. So if you look at full year fiscal '06, the
                    model has us at about 36 percent operating margin for '06
                    and what we said is we're targeting 35 percent for fiscal
                    '07 with comparable gross margins. So, the increase in
                    engineering E to R, the one point we talked about would flow
                    through to operating income would be our target. And, hold -
                    at least we're comfortable at this point is what we've said
                    at the $1.66 consensus for fiscal '07.

Douglas Whitman:    OK. Thanks.

Tony Massetti:      Sure.

Operator:           I'll move next to Henry Naah with Lehman Brothers.

Henry Naah:         Hi, Guys.

Tony Massetti:      Hello.

Henry Naah:         Just gonna hammer on the expenses one more time here. Try to
                    take it from a different angle. You know, the one percent
                    uptake in engineering expenses, you know, I think in my
                    model for '06 and '07 we're looking at $90 to $95 million of
                    engineering expenses. So, using a one percent increase, I'm
                    guessing that assumes that that line will come up by about
                    $1 million, is that what you are trying to convey here?

Tony Massetti:      It's one percent of revenue, right Henry? So, the seventeen
                    to twenty percent is an E to R. So the increase from 16 to
                    19 to 17 to 20% expense to revenue.

Henry Naah:         OK. So then we're looking at maybe five million in revenue
                    additional expenses per year?



Tony Massetti:      Yes, probably in that range. It's a little hard to tell.
                    HK's comment about headcount, we haven't finalized or worked
                    out all those details so we'll update you more on headcount
                    and expense rates growing on our earnings call in early May.

Henry Naah:         OK. And, you guys says, this deal can close in early April?

Tony Massetti:      Early April, yes.

Henry Naah:         OK. And, I guess just one last question, have you locked up
                    some of the engineers from PathScale?

HK Desai:           I think when we acquire technology -

Henry Naah:         Actually HK, can I ask the question a different way? Are
                    there any kind of proprietary patents or anything that
                    PathScale has that you've gotten, or have you been able to
                    assign some of the engineers up?

HK Desai:           So, as far as IP is concerned, they are coming to us. And as
                    far as engineering is concerned, whenever we acquire a
                    technology company, which we have done a few of them in the
                    last five or six years, and I do want to ensure for us, that
                    we retain engineering talent, which is the most focus we
                    always have and our track records say that in the past, when
                    we acquired technology companies we haven't lost a key
                    engineer or key employee in any of the acquisitions, not
                    even a one.*

- ----------
*    Mr. Desai's statement regarding employee retention of key engineers and key
     employees was not intended to be taken literally, but was intended to
     convey the message that retention of key engineers and key employees in
     connection with acquisitions is a primary objective of QLogic.



Henry Naah:         Sounds like a great track record.

Tony Massetti:      Yes.

Henry Naah:         OK. Thanks, guys.

Tony Massetti:      Sure.

Operator:           We'll go now to Paul Mansky with Citigroup.

Paul Mansky:        Yes, thank you. I have a few questions, kind of related to
                    the prior questions. Does the transaction carry any type of
                    payout? You're pretty good about achieving revenue targets
                    or maybe future OEM qualifications?

Tony Massetti:      We're not prepared to talk about the deal terms, Paul.

Paul Mansky:        OK. Maybe a separate tack then. Previously, with the ANCOR
                    acquisition, I believe you'd been developing some InfiniBand
                    technology in the house, will any of that technology be able
                    to be dusted off and/or usable in conjunction with the
                    acquisition announced today?

HK Desai:           We never had HCA technology. I mean, we had some InfiniBand
                    technology at QLogic that we started but, no we don't have
                    any technology on the HCA at all.

Paul Mansky:        OK. And, then lastly, obviously between Troika, today's
                    announcement, there's - you made a point to bring up
                    virtualization discussion on the last earnings call, can we
                    assume that you may not be finished here over the near to
                    intermediate term with respect to your acquisition activity?



HK Desai:           If you look at us in 2005, we have a divesture, of the disk
                    controller business, we acquired Troika, for virtualization
                    technology, now we acquire PathScale for a system network
                    area fabric, so, I mean, I think we're busy enough right
                    now.

Paul Mansky:        That's good news. Thank you.

HK Desai:           Thank you.

Operator:           Once again, a reminder, it is star, one if you would like to
                    ask a question. We'll go now to Min Park with Goldman Sachs.

Min Park:           Asked and answered announcer, thank you.

Operator:           We'll go on to Jared Rinderer with RBC Capital Markets.

(Tom Curlin):       It's (Tom Curlin). Tell us about the technology in terms of
                    ASIC versus firmware. These guys actually have HCA, ASIC
                    hardware along with the firmware? Or are you sourcing the
                    ASIC from a partner?

HK Desai:           No, they have an ASIC, they have their own ASIC technology.
                    They also have firmware and software technology. They also
                    have compiler technology for the HPC market so you can
                    compile applications. So combining all technology it
                    provides low latency, high bandwidth technology for the HPC
                    market.

(Tom Curlin):       And, is this the 10 gig manifestation of InfiniBand? Or even
                    a higher type of bandwidth?

Rick Franz:         It is 10 gig, (Tom).



(Tom Curlin):       Any switching ASIC technology? Or you're just doing the HCA
                    side and other vendors are doing the switch piece?

HK Desai:           We are just doing the HCA side.

(Tom Curlin):       Alright. Thank you very much.

HK Desai:           Sure.

Operator:           We'll move now to Mark Moskowitz with JP Morgan.

Mark Moskowitz:     Thank you. Hi, guys. A couple questions if I may. It seems
                    today your move validates what's InfiniBand at least with
                    respect to server clustering. But, I want to get a sense,
                    maybe you could touch on the longer term inspiration. Do you
                    see InfiniBand eventually moving into storage and impacting
                    your fiber channel, a piece we have (inaudible)) already
                    come out with a product. There's rumors that Network
                    Appliance may come out with one over the next twelve months
                    or so, so I was just wondering if you could touch on that
                    first?

HK Desai:           So, I mean, our strategy is to enter the more HPC market,
                    high performance computer market. We don't expect to have
                    that much technology going into storage, I mean, storage
                    already has a Fibre Channel technology, which is the
                    preferred deployment in the data center. We also have now,
                    iSCSI anyway. So anyway, there is enough technology there.
                    And, I don't think we expect InfiniBand to really penetrate
                    storage interface, at least in the near future.

Mark Moskowitz:     OK. And, as then as far as the expenses get, getting back to
                    the expense subject again, I want to get a sense, do you see
                    anything with PathScale as far as anything in the
                    manufacturing processes that they have versus (QLogic's)
                    that you could maybe extract in terms



                    of applying more of your legacy type of processes to drive
                    better margin and improvement to kind of offset that
                    increase in terms of the (R&D)?

HK Desai:           So, I mean, if you look at, we have a better operational
                    experiences and a lot of experience in this thing, so we're
                    going to apply our process for the manufacturing process and
                    relationships so we can leverage some of the cost with them
                    and they've done extremely well on that, so there's a lot of
                    synergy about those, they have a great technology, they have
                    great AC, they have great firmware, great software, and you
                    think with QLogic's operating staff they can leverage the
                    cost and time to market for those products.

Mark Moskowitz:     OK. Lastly, if I could, as far as the purchase price, maybe
                    you could give us something in terms of how that was
                    derived, given that it was a pre-revenue type of company,
                    was there another suitor out there you had to compete
                    against in this deal?

Tony Massetti:      We really can't talk about potential other suitors, but, you
                    know, we looked at all the traditional metrics, marked
                    discounted cash flow, future protections of revenue and
                    profitability and working with their investors and, you
                    know, came up with a $109 million purchase price, which is a
                    very fair price for QLogic, as well as the investors.

Mark Moskowitz:     OK. Thank you.

Tony Massetti:      Sure.

Operator:           Well, we're next here with Steve Berg with Punk Ziegel.

Steve Berg:         Hi. I wanted to touch on the post seven estimate number
                    again. Would it at least be fair to say that, as a result of
                    some expense in early '07, that earnings going to skew to
                    the latter half of '07?



Tony Massetti:      Yes, it's a little early, Steve, to talk about the quarterly
                    skew for fiscal '07, you know, we haven't closed on the
                    transaction, and, you know, there's a lot of details still
                    to be worked out. So, that's why we wanted to speak to the
                    full year fiscal '07 and just give you overall operating
                    model and, you know, and say that we're comfortable with the
                    current consensus of EPS, but you know, we'll be able to
                    give you more of a - more color on the quarterly skew on our
                    March call.

HK Desai:           Also understand, in the new technology and new markets, OEM
                    design wins, you know, timing of that can change it can be
                    delayed or it can pushed-out, so what we have done is said,
                    OK, we can look at this and spread it out over the years and
                    where we can we are targeting 35 percent operating Income
                    and target and $1.66 EPS, I think that's a key for us
                    anyway. And those things can change and we'll view the
                    quarterly guidance every quarter anyway, and that way we can
                    give more detail, but right now I think we can say we are
                    comfortable, even the timing can little bit shift toward the
                    later part.

Steve Berg:         OK. That's helpful. One last question, I don't know, is
                    there anything you can tell us about the unvested stock
                    option, any ancillary data at all about that?

Tony Massetti:      No, there's really nothing that we can discuss at this point
                    other than to say it won't impact materially QLogic's
                    disclosure on stock options. You know, we've been running
                    about eight cents a quarter, it's what we put in our
                    footnote for our Qs, but that does include stock options for
                    the HDC business, which has been divested, so we're in the
                    process of reworking those numbers, so it'll be something
                    less than eight cents and the unvested options related to
                    PathScale are not material.

Steve Berg:         OK. So let me just see if I understand that. So, basically,
                    you're saying if you're taking out some and adding back some
                    then you net the same.



Tony Massetti:      No, less.

Steve Berg:         OK. You net less. Thank you very much.

Operator:           We'll go now to a follow up from Harsh Kumar with Morgan
                    Keegan.

Harsh Kumar:        Yes, hi. Just a point of clarification, HK or Tony. Are you
                    expecting revenues from this company in calendar '07, second
                    half or fiscal '07 second half?

HK Desai:           Fiscal '07.

Harsh Kumar:        Got it. Thank you.

Operator:           We'll move on to Aaron Rakers with AG Edwards.

Aaron Rakers:       Yes, hi guys. Just one question, just wondering, as we look
                    out into the latter part of fiscal 2007, now I'm trying to
                    gauge what, you know, we should be looking for, in
                    particular possibly, out of the server venders as kind of
                    indications that, you know, the InfiniBand market is, you
                    know, starting to materialize. Any help there would be
                    greatly appreciated. I'm just trying to gauge, you know,
                    what maybe we should be looking at going forward?

Rick Franz:         I mean, there's lots of things we can look at from the
                    server venders. But it's primarily products destined for the
                    high performance computing market. Servers that are designed
                    specifically with the InfiniBand in mind. OEMs announcing
                    potentially InfiniBand products.

Aaron Rakers:       OK. In terms of your total addressable market forecast that
                    you gave, that was your own forecast assumptions, or are you
                    looking at a third party resource, how do you get to that
                    number, that 400 million number?



Rick Franz:         It is a combination. It is both looking at what analysts
                    have put forth in terms of some estimate for ports, plus
                    discussions with OEMs and end-users. But, basically, it's
                    our own number at this point.

Aaron Rakers:       OK. Thank you, guys.

Operator:           We'll go now to a follow up from Clay Sumner with FBR.

Clay Sumner:        Thanks. You guys, HK, do you think OEMS will want to do more
                    dual sourcing with InfiniBand adapters than they did early
                    on with fiber channel adapters. Is there anything about
                    InfiniBand driver technology that might make it easier or
                    cheaper to do a qualified drivers?

HK Desai:           In any new market to get traction you have to get a couple
                    of suppliers. If you don't have two suppliers then the
                    market just doesn't happen anyway. So, I'm sure those guys
                    will be looking at it from that perspective. It doesn't have
                    to be dual sourcing but then you have multiply suppliers for
                    this market, so I think this is a positive sign for this
                    market.

Clay Sumner:        I guess put it another way, are there the same kind of
                    barriers to entry around driver qualification that there
                    were early on the fiber channel, HVA?

HK Desai:           I won't say it's exactly the same, but yes there is still
                    qualification cycles and barriers to entry just like fiber
                    channel.

Clay Sumner:        OK. Thank you very much.

Operator:           And, we'll go now to a follow up from Shebly Seyrafi with
                    Kaufman Brothers.



Shebly Seyrafi:     Just wanted to see if you guys wanted to take an opportunity
                    here and talk about current business. Any update on the
                    current quarter?

Tony Massetti:      So, tracking to our forecast expectations, Shebly, so
                    linearity has been very similar to the past few quarters.
                    So, we're tracking well.

Shebly Seyrafi:     Which is good in your opinion?

HK Desai:           We're tracking to expectations.

Shebly Seyrafi:     OK. Thank you.

Operator:           And, gentlemen, there are no further questions. I'll turn
                    back the call to you for any closing comments.

Tony Massetti:      Thank you for joining us for this conference call. We look
                    forward to discussing our fourth quarter and fiscal year
