Competitive Platform Shootout: vSphere vs Xen vs HyperV – TA8188

12.24

testing new live blogging plugin for wordpress…hoping for better luck this time.

about to start here shortly…

switching to vmworld press wifi…AT&T latency super high…

Session will review performance of vSphere, hyperv and citrix

At MS teched, vsphere was picked as “best of tech ed”

Hypervisor footprint, server 2008 r2 w/ hyperv is 3.6GB installed.

Lots of talk about USB flash drives and installing esxi on them. fully supported….(there is a current post on the VMTN forums about the size of flash drives needed for install. From what was mentioned 1GB is PLENTY.)

MS reports “single pan of glass”…. false marketing. Perfmon needed for monitoring low level performance. increases complexity.

couple hits at MPIO support for iscsi and easy out of the box. – hmm he must not have visited the vmtn forums lately w/ the recent failover problems of a nics (unused/standby problems of nics).

mentioning update manager for vcenter… hmmm talking about upgrading entire evironment with a few clicks. – personally I prefer using vMA or Powercli at the CLI to update hosts. lots of reported “odd” issues on the vmtn forums when using update manager. let’s not forget update manager will no longer update Windows machines after current release.

reviewing hyperv restrictions and limitations… VMFS makes shared storage easy.

session is turning into more of a “vsphere overview”… where is the comparison of Xen??

some hits at xen server using LVM files. “hide” vms in esoteric layouts. talking about storage vmotion and expanding volumes.

talking about limiting iops for vms and controlling shares level.

hyperv not advised thin provisioning. xen server is incomplete (? not sure about this)…

snapshots- hyperv not recommended , removal causes downtime, xenserver latest release adds guy support.

next speaker is up (sorry missed his name)… reviewing system up time features and explaining FT, HA, memory overcommitment and resource pools. — couple features being mentioned about FT needing to be thick disk…looks like this isnt going away anytime soon. — hyperv doesn’t have FT —

Going to end this session…. time for lunch. Seems like the rest of the session will be about basics of HA and affinity along with host affinity. Most of these topics are covered heavily in Administrator Guides.

VMWorld 2010 – It’s Finally Here…

It feels like it has been longer than a year since the last VMworld event but the largest virtualization IT event in the world is finally here.  I expect the turnout for this year’s conference will surpass last year’s attendance.  This year is already becoming a massive social media event. I am thoroughly amazed by the amount of buzz on Twitter and other blogs, not to mention the major increase of vendors over last year.

This will be my first year actively tweeting and blogging from the conference. VMware has compiled a great list of active bloggers that will be covering the conference all week, the list can be found here: http://www.vmworld.com/docs/DOC-4671. It will be hard for me to cover everything that is occurring at the conference, but I am going to do my best to provide coverage on the most important topics and sessions for my readers. I recommend following me on twitter @s1xth for up-to-the minute status updates. Hopefully VMware and the Moscone Center invested in extra Wireless AP’s this year and the recent AT&T network upgrade in San Francisco will improve the network connectivity so we won’t experience issues like last year.

Apple also announced today that they will be holding a large press event right around corner from VMworld at Yerba Buena Center for the Arts on Wednesday morning. It’s going to be a busy week for the city of San Francisco!

I wanted to provide my readers with my TOP 5 list of things that I am most looking forward to:

1. VMworld Party – Can’t miss this, always an amazing time with great food and drinks while networking with great IT folks!

2. Labs – This year VMware is offering 18,000 lab sets and 25 different lab classes. This was greatly needed last year and I am happy to see that this number has gone up! It really is something NOT to miss!

3. Sessions - Of course the sessions are awesome, but sometimes excessive power points can become overwhelming….when that happens, go to a lab!

4. Solutions Exchange – Aka vendor/swag land…. This year’s swag should be great, even better then last year.

5. Parties! - Should be some crazy nights coming up!

Keep checking my blog and  my twitter account for upcoming news and announcements from the conference! Looking forward to seeing all of you there!

I also added a Twitter feed to the side of my blog page to display any #VMworld hash tag tweets for those of you who want to keep up to date with any VMworld happenings.

Breaking: Dell to Acquire 3PAR

Update: 8/25/2010 – Looks like this isn’t a done deal quite yet. HP has now submitted a bid to acquire 3PAR. Dell has three days to counter the HP offer, I can’t wait to see how this will end up!
-
It is a busy news morning already in the tech sector…Dell just announced that they will be acquiring 3PAR Utility Storage company. This announcement comes as a surprise to me and many others in the industry.
In the Dell Press Release, it is stated that the purchase “will give their customers more value and more options”. Since the 3PAR product line consists of high-end Fiber Channel offerings, it sounds as if Dell will be making 3PAR their higher end storage offering. If this is the case, maybe we will see the prices on EQL arrays come down, so the SMB market can take better advantage of the great EQL product offerings.

Check out the press release below:

Dell Agrees To Acquire 3PAR For Virtualization-Optimized Storage

http://content.dell.com/us/en/corp/d/secure/2010-08-16-ir-release.aspx

  • 3PAR extends Dell’s storage capabilities, enabling Dell to help customers capitalize on the ‘Virtual Era,’ with a goal of reducing overall data management costs by 50 percent
  • 3PAR provides a leading, virtualized, utility storage platform addressing limitations of monolithic and modular arrays; reducing storage administration costs by up to 90 percent and infrastructure costs by up to 75 percent

  • 3PAR’s multi-tenant, clustered architecture enables IT organizations to deliver software and hardware as a service, offering an agile, efficient storage infrastructure platform optimized for highly-virtualized data centers and cloud computing
  • 3PAR accelerates Dell’s momentum in delivering open, capable and affordable storage options, adding to its industry-leading portfolio of PowerVault, EqualLogic and Dell/EMC

Dell has signed an agreement to acquire 3PAR, a leading global provider of highly-virtualized storage solutions with advanced data management features, including dynamic tiering and thin provisioning, for multi-tenant cloud-computing environments. The transaction is valued at approximately $1.15 billion, net of 3PAR’s cash. Terms of the acquisition were approved by the board of directors of each company.

In the ‘Virtual Era,’ Dell is driving an open and integrated approach to data management. Dell is delivering increased efficiency with a goal of radically reducing data management costs and significantly streamlining operations. These savings enable Dell customers to make room in their budgets for other strategic investments. 3PAR’s product portfolio complements Dell’s goal to make IT simpler and more affordable.

As a pioneer of thin provisioning and other storage virtualization technologies, 3PAR has designed its products to minimize upfront and ongoing capacity purchases, and to reduce power consumption and energy costs. 3PAR’s multi-tenant, clustered storage architecture is the underlying technology platform for IT organizations to build agile and efficient virtualized IT infrastructures for flexible workload consolidation. 3PAR provides rapid provisioning and predictable performance for customers facing ever-increasing storage capacity requirements.

3PAR’s storage arrays are designed to overcome the limitations of traditional modular and monolithic arrays. 3PAR addresses the problem of costly, complex, and rigid IT environments and enables organizations to treat storage as a utility— allowing them to use and pay for only the capacity and performance they need, and only when they use it.

Dell plans to make 3PAR an integral part of its industry-leading storage portfolio, including PowerVault, EqualLogic and Dell/EMC. With 3PAR, Dell will offer innovative systems and customer choice at every storage tier, from direct-attach to highly-virtualized, clustered SANS.

3PAR was founded in 1999 and is headquartered in Fremont. After closing, Dell plans to maintain and invest in additional engineering and sales capability. There are no plans to move the current operations.

Tender Offer, Closing and Initial Integration

Under the terms of the agreement, Dell will commence a tender offer to acquire all of the outstanding common stock of 3PAR for $18 per share in cash. The transaction, which is subject to customary closing conditions, is expected to close before the end of the year.

Based on current estimates, the transaction is expected to be accretive to Dell non-GAAP earnings in its Fiscal Year 2012.

Quotes

“We have aligned our storage offerings over the last several years to provide our customers choice and value,” said Brad Anderson, Dell senior vice president, Enterprise Product Group. “3PAR brings the same values of performance, agility and ease-of-use to higher end, virtualized storage deployments as EqualLogic does for the entry-level and mid-range, rounding out our industry-leading solutions portfolio.”

“3PAR has consistently provided customers with the ability to do more with less,” said David Scott, President and CEO of 3PAR. “With Dell we combine a powerful, virtualized storage platform with an outstanding distribution network to deliver this value to an even broader set of customers.”

Tech Alert: Update Regarding v5.0.0. and v5.0.1 EQL Firmware

I just received the following e-mail from Dell regarding the Firmware 5.0/.1 problems along with a statement on resolution. I wanted to post this for my readers that do not receive these e-mails. I am working on a more expansive blog post regarding the firmware 5 problems and will be posting it shortly. In the mean time, glance through the email below which explains the current status of the firmware. Stay turned for more information.

Dear Customer,

Update

Dell has identified the root cause of all the issues listed below for PS Series Firmware V5.0.0 and 5.0.1, which were previously communicated to you.  Dell is planning to release an updated firmware version (v5.0.2) addressing these issues on or around 08/30/2010.  Dell will contact you again as soon as  the update is available for download and installation.

Do Not Install Dell EqualLogic PS Series Firmware Versions 5.0.0 or 5.0.1

According to Dell’s records, you have recently downloaded v5.0.0 or v5.0.1 of the Dell EqualLogicTM firmware. Dell has become aware of potential issues with the installation and operation of these versions of the firmware. Under certain conditions, any or all of the following might occur:

• Volumes might not come online properly immediately after the install.

• Replication might not occur properly.

• VMware V4.1 Zero offload performance might be affected.

If you have not yet installed the V5.0.0 or V5.0.1 firmware updates, Dell recommends that you do not install at this time. Dell is working to resolve these issues in future releases.

If you have either of these firmware updates installed and are experiencing any issues with your

array(s), please contact your local Dell EqualLogicTM technical support team for assistance.

Sincerely,

Dell EqualLogic

VMworld 2010 Theme – Virtual Roads, Actual Clouds – New Theme for the Blog!

VMworld 2010 is right around the corner…I can’t believe it’s been a year already since VMworld 2009. Last year’s conference was a great experience. I anticipate that this year will be even bigger, with twice the number of labs available and an all new scheduling format. I will be blogging live from the conference all week.

I expect the entire week  of VMworld to be crazy, fun-filled, entertaining and, of course, highly educational. This year’s conference will be covered by tons of social media sources and fellow bloggers. Let’s hope the AT&T network will be able to handle the large volume of ‘geeks’ in SF blogging Paul Maritz’s opening speech on Wednesday. I will be attending quite a few sessions, mostly centered around VDI/View 4.5, and of course some Cloud sessions. I am planning on making as many posts as possible during the conference to keep all of my followers up-to-date on any news coming out of the conference.

I hope all of my fellow bloggers have safe travels to the conference and that everyone enjoys their stay in the great city of San Francisco. Keep an eye out for my live blogs and check the new page I added – Live Blogging Schedule.

Tech Alert: Critical Information Regarding EQL Firmware 5.0 and 5.0.1

I received an email earlier this morning from Dell/EQL HQ regarding firmware 5.0 and 5.0.1. EQL is now recommending against the installation of the 5.x.x firmware on all model arrays. I have posted the email I received below since I have been told of some EQL users are not on this email alert group. I am aware of some users that have installed firmware 5 on their arrays and have not had problems, but I am not sure if they are running vSphere 4.1. These issues ‘sound‘ like they stem around vSphere 4.1 and possibly some last minute changes that VMware made to their code that is causing problems. I am hoping to receive some more information on what is occurring in the coming days.

I will make a post once EQL has removed this alert and released an updated firmware for users (think 5.0.2, etc) with the proper fixes for the problems listed below. If you have upgraded to firmware 5, I would just keep a close eye on your arrays for any performance issues and contact EQL support if you experience any of these symptoms.

EqualLogic MEM Performance Enhancements – Test Results

There has been a lot of interest in my post regarding the EqualLogic MEM plugin for vSphere 4.1.  I haven’t had a chance to test the release yet on my EQL array at this time, but I had to make a post about the awesome performance review from fellow EqualLogic user Graham located here: http://bit.ly/cOVINJ. Graham did a GREAT job on his performance assessment and includes some great graphs and numbers that show the awesome performance improvements when using the EQL MEM plugin for vSphere 4.1. I highly recommend reviewing the numbers he achieved, as the results are staggering and really make the VMware iSCSI multipathing plugin look fairly weak in comparison. The only question that remains for customers (w/ Enterprise Licensing of course) is, what are you waiting for?! Install it!

EqualLogic Firmware 4.3.6 – Critical Upgrade for PS Series Arrays

EqualLogic has released a new firmware update for EqualLogic customers which fixes a number of critical and potentially serious issues. I was alerted to this firmware release earlier this month. The fix list mentions quite a few major problems that have been corrected. I have not upgraded to firmware 5.0.1 yet as I usually wait a few months before applying major revision upgrades to my production arrays. However, I will be applying this latest firmware to my production arrays in a week or two.

It is also worth mentioning that Dell sent out a mass Tech Alert email this morning to all EQL customers with a title of “Critical Alert for Customers”. The arrays mentioned in the email that are directly affected are the PS6000, PS6500 and PS400E arrays. Even though PS4000 arrays are not listed in the email, I have been informed that this patch is still Critical for PS4000 series users. I strongly recommend all customers to schedule time to apply this firmware update. This coming weekend is end-of-month and many companies (like mine) do not permit the installation of new software over this period due system processes that can not be interrupted. I will be scheduling time the first weekend in August to apply this update.

Email from Dell/EQL:

Critical Alert for Customers

V4.3.6 Firmware Now Available;

Critical Fixes Implemented;

Dear Valued Customer,

With the release of EqualLogic™ PS Series Firmware Release V4.3.6, a number of potentially serious issues have been resolved.  Customers who are using any of the products listed below are strongly urged to upgrade to V4.3.6 or higher at their earliest opportunity:

  • EqualLogic™ PS6000, PS6500 or PS400E arrays
  • EqualLogic™ PS100 arrays with 750GB disks
  • Windows 2008 Clustering Software

V4.3.6 contains a number of important fixes which affect all arrays, and Dell encourages all customers to apply this update. Please refer to the V4.3.6 Fix List for complete details.
