Analysis
#NetAppSynergy

7. 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
