Thanks. We'll let you know when a new response is added.

There are two major things to think about. Storage IO capacity and CPU load. If you try and push the disks to hard performance will be impacted. Same goes for the CPU.

If lots of users will be logging in at the same time, you’ll need some very fast disks to compensate for the boot storm that happens. If the users will be using high CPU applications like Photoshop or something then you’ll need a lot more physical servers to ensure that there are enough CPU resources available.

    Memory allocation needs to be considered. How much memory per client and how much dedicated to the host server.Also, network bandwidht/throughput needs to be addressed.

    I realize that if VDM Agent is installed on the template and it is old then it affects the performance of VDI. Also many organizations that have tried to deploy VDI with a shared storage infrastructure that has a fixed amount of storage available. It affects when more desktops are added without increasing the total number of shared storage infrastructure. Another cause with VDI, the virtual desktop may traverse multiple switches each time & it reads and writes data to disk. This process can increase latency to as much as possible and decrease desktop performance. Thanks--

    "It affects when more desktops are added without increasing the total number of shared storage infrastructure" It is not the storage capacity that would affect performance on shared storage implementations. The bottleneck would be the number of IOPS (I/O per second) available for each desktop.
