Citrix PVS Resource Usage Part 1
Some people are saying that PVS is complex. I personally don’t think that PVS is complex looking from an infrastructure endpoint, but it can be complex to understand the concept of PVS and the new way of working. When people get that part, the complexity is not a bottleneck anymore. But when people understand the way of working understand new questions are often raised. How many bandwidth does this solution requires, which hardware resources requires these PVS server to serve their role. In this article series I’m diving into this topic. First I will discuss the theory of the resource usage by Citrix, followed by real life figures. The real life figures are divided in two parts: daily usage and boot (storm) usage. As just mentioned we are starting with the theory.
If you take a look at hardware resources the following components can be recognized: CPU, Memory, Disk and Network. Let’s take a look what Citrix is describing about these components.
Physical v Virtual
This discussion is actually outdated nowadays, but to be accurate I will mention it shortly. Hypervisors are currently that powerful, they are capable of processing heavy workload without any problems. PVS servers are often seen as heavy workload servers, so were discussed to set-up physically for a long time. However nowadays PVS servers can be easily virtualized. As in many organizations the starting point is that servers should be virtualized, I currently see only virtualized PVS servers.
