XenServer PVS Accelerator Cache Sizing


How large should we make our PVS Accelerator cache? Too large and we waste resources. Too small and we lose the performance. Let's take a step back and recall our best practice for sizing the RAM on Provisioning Services.  We would typically say allocate 2GB of RAM for each vDisk image the server provides.  This… Continue reading XenServer PVS Accelerator Cache Sizing

Provisioning Services Accelerator


An interesting new feature was included with the XenServer 7.1 release: Provisioning Services Accelerator. In a single sentence, PVS Accelerator overcomes PVS server and network latency by utilizing local XenServer RAM/Disk resources to cache blocks of a PVS vDisk to fulfill local target VM requests. Take a look at the demo video to see: https://www.youtube.com/watch?v=l_vhMf3SFks… Continue reading Provisioning Services Accelerator

Sizing Windows 10 and Windows 7 Virtual Machines


After reviewing all of the scalability tests we conducted over the past few months, I thought it was time to revisit the recommendations for sizing Windows 10 virtual machines.  I also reached out to Nick Rintalan to see if this is in line with what is currently being recommended for production environments (if you disagree,… Continue reading Sizing Windows 10 and Windows 7 Virtual Machines

Microsoft Windows 10, Citrix XenDesktop and Logon Time


How long does your Windows 10 logon take? Logging into my lab, my logons felt long. True I'm not using server-level hardware that you would see in production, but my logon times felt too long because I don't have logon scripts, complex group policy preferences, or even massive profiles. After reading the Rule of 30… Continue reading Microsoft Windows 10, Citrix XenDesktop and Logon Time
