Storage Sizing – Key Takeaways

Performance

• Size for 25 IOPS per VM if you need a conservative estimate

• Liquidware / Lakeside to do application IO analysis

• Size for 30% read, 70% write

• Cater for read storms

• up to 200 IOPS per VM

• Use CBRC (aka VSA)

• On average 70% reduction in read IO on boot storms

• Validate with storage vendor

Capacity

• Linked Clones and SE Sparse can keep VM size to ~4GB

• 100% Memory Reservation to avoid vmswp disk

• Keep in mind space for Replicas

• No support for SE Sparse in Virtual SAN

View Design Guide

• Calculations for local and shared storage

• Parent VM

• Replica

• Linked Clone

• vSwap

• Log

• Disposable Disk

• Persistent Disk

• VSAN introduces a whole new calculation!

CONFIDENTIAL 17

• Each RDS host maximum session limit

• Size each RDS Farm with identical sized hosts

• RDS hosts within a farm should contain the same applications with the same configuration

– Executable paths must be the same

• Less powerful RDS hosts can be configured with a lower session limit

Default max sessions:150

Consider separate farms for specific application sets

Sizing – PCoIP

• Optimize and test (multiple users)

• Client-side-caching improves performance - Check client compatibility

• Rule of thumb for office user: 160-250Kbps per session

• Expect bursts of 4MB or more with video on an unconstrained network

Configuration Best Practices

Configuration Best Practices

View Storage Acceleration

(CBRC)

Always enable VSA(on by default)

– Will reduce boot and login storm IOPS

Space-efficient Sparse

(SE-Sparse) disks

Ideal for linked clones. Not supported for Virtual SAN

Replica VM Place the replica on a faster tier on storage (Flash/SSD)

Memory reservation Size hosts for 100% memory reservation eliminate vmswap

Connection Servers Configure with minimum of 12GB RAM (for up to 2,000 sessions)

Use pair of Connection Servers for internal access and a separate pair of

Connection Servers for external access (paired with Security Servers)

Security Servers Essential component for external access. Use the PCoIP Secure Gateway

feature when View Clients do not have access to desktop subnet
