Executive summary

Scope: Citrix Virtual Apps for Customer.
Design load: 1,331 named users and 932 concurrent sessions/desktops at the 3-year growth horizon.
Recommended platform: Hyperconverged (HCI): Nutanix AOS with AHV, Replication factor 2 (1N/1D).
Hosts: 6 across 1 cluster(s), each sized for N+1 (worst-case utilization after failure: CPU 68.4%, memory 58.9%).
Compute: 195 physical cores required (384 installed); memory 1,390 GB required (3,072 GB installed).
Storage: 6.13 TB usable / 13.62 TB raw on the virtualization platform; 10.65 TB of profile and user data on existing file services.
Performance: approximately 1,652 peak IOPS (2,148 IOPS with headroom); HDX bandwidth at peak 203 Mbps.
Status: Preliminary estimate - validation items open - 0 critical, 0 warnings, 53 knowledge-base rules pending approval.

This sizing is an engineering estimate. It is not certified by Citrix or any hardware vendor and must be validated (load testing / proof of concept, vendor configurators) before production use.
