Storage Cost per Desktop Analysis

#NetAppSynergy

Sizing Assumptions

Extrapolation based on NetApp performance testing for Citrix PVS &

our VDI Sizing Tool

– LoginVSI heavy workload (10 IOPS/desktop to storage; majority of read IOPS served

by PVS read cache)

– Apps latency within acceptable limits (VSIMax number below 1500)

All VMs boot within 10 minutes

Capacity: 6GB-17GB per user (use case dependent)

– 35% dedupe savings for Citrix Personal vDisk and CIFS share

IO Acceleration:

– Writes: NetApp IO coalescing

– Read IOPS:

FlashCache for CIFS read traffic

Citrix PVS caches majority of VM reads

NetApp controller utilization <50% during steady state
