For the lowest latency VDI VMs, the VMs should be running from in-host RAM. The combination of two facts – that RAM is the lowest latency media there is, and it is on the same motherboard as the host CPU, makes this storage architecture for VDI higher performing than any other….
Improve VDI Performance
VDI deployments are plagued with boot storm problems as they scale up. Boot storms are caused when many VDI users simultaneously boot up their virtual desktops, say first thing in the morning when they come to work. When a large number of VDI VMs are simultaneously powered on and their…
The big difference between the two is that VSA can cache only reads and only from the Master/Replica VM in Horizon VDI.1,2 VirtuCache caches reads and writes from all server & desktop VMs, and it can cache to TBs of in-host SSD or RAM, with the goal of servicing all storage…
Both cache ‘hot’ data to in-host RAM, but the differences between Citrix MCS Storage Optimization and VirtuCache are many. The top three are: – MCSIO works only for non-persistent Xenapp / Xendesktop VMs.1 VirtuCache works for all VMs on the ESXi host; – Citrix MCSIO can cache only VM writes…
