  1. You don’t have to be a rocket scientist to see value of RAM Cache

    Windows-Not the Operating System Kind!

    A few years ago, we replaced all of our windows in our home (I'm talking about the panes of glass you look through, not the operating system). In the process, of course we talked with a few different companies who stopped by.  We went through their product portfolio and brought along samples. One demonstration stuck with me. The sales person, placed his sample window flat ...

  3. The Death of IOPS – Part 2

    I sort of cheated since there isn't a "Part 1" with this exact same title, but I have my reasons for changing the title and this is partly why I'm writing this second article about the same topic.  The first article is entitled "Citrix Puts Storage 'On Notice'" and can be found here.  In case you haven't had a chance to read it yet, I talked ...

  5. Diving deeper into the latest XenDesktop 7.5 IOPS results

    As you saw in a previous blog, XenDesktop 7.5 is able to achieve an average IOPS value of less than 1/10th per user. Of course when you put out unbelievable results like this you hear a lot of comments trying to find holes in the results or test procedures. This is as it should be as it is part of any good scientific method. In order ...

  6. Citrix Puts Storage ‘On Notice’!

    That's right - we just put storage throughput and IOPS officially "on notice"!  And in turn (whether we really meant to or not), we made every storage company that got into business over the last ~6 years (since we introduced VDI) to solve the dreaded IOPS problem think twice.  Citrix just threw down the gauntlet and it means we can finally stop talking about IOPS. ...

  8. The Changing Read/Write Ratio for XenApp

    As technology changes, so too does a recommendation. For years when you deployed XenApp servers with Provisioning Services, the storage Read:Write ratio would be 10:90. This is still the case in most scenarios. But in analyzing the latest data from the Citrix Solutions Lab, who were testing the "RAM Cache with Overflow to Disk" option, we encountered some results that will make us revisit some of ...

  9. Demystifying KMS and Provisioning Services

    Beginning in Provisioning Services 5.6 SP1, Citrix introduced a new feature designed to facilitate Key Management Services (KMS) license activation of the Operating System and of Microsoft Office installations for images streamed in Standard (Read-only) mode. In this blog post, we’ll attempt to remove some of the mystery surrounding the implementation of the KMS license activation feature in Provisioning Services. The following points will be discussed ...

  10. Turbo Charging your IOPS with the new PVS Cache in RAM with Disk Overflow Feature! – Part One

    With PVS 7.1 and later you may have noticed a new caching option called “Cache in Device RAM with Hard Disk Overflow”.  We actually implemented this new feature to address some application compatibility issues with Microsoft ASLR and PVS.  You can check out CTX139627 for more details. One of the most amazing side effects of this new feature is that it can give a significant performance ...
