Omnissa Sizer by Niyyasoft

VDI pools (floating or dedicated, instant or full clones), RDS farms and NVIDIA vGPU workloads, each with its own users, concurrency, desktop size, profile and data storage, I/O and bandwidth.

Horizon infrastructure from the Omnissa Configuration Maximums: 4,000 sessions and one logon per second per Connection Server, N+1, 20,000 sessions per pod, Cloud Pod Architecture, and standard or extra-large Unified Access Gateways.

Platform sizing for VMware vSAN ESA and OSA, Nutanix AOS, or three-tier FC, iSCSI and NFS storage: CPU, memory, capacity after the storage policy, IOPS, host failures to tolerate and cluster limits.

Every value is classified — official, customer, assumption, calculated or vendor validation — and every formula is shown with its inputs and the Omnissa document it comes from.

Five scenarios side by side: baseline, balanced (recommended), performance, failure with hosts out of service, and growth over the planning horizon.

Logical, physical, network-zone and firewall diagrams drawn on the server, with zoom, pan and SVG or PNG export. No topology data leaves niyyasoft.com.

A firewall matrix built from the documented Horizon port flows for the features you select, with consolidated rules, a zone matrix and an Excel export to review with your security team.

Projects with immutable revisions, side-by-side comparison, sharing with colleagues and a full audit trail, plus a hardware bill of materials with no invented models or part numbers.

Word, PowerPoint and Excel exports from the same saved revision, so the report, the deck and the workbook always agree. The Excel formulas re-check the saved results.
