THE LEGACY

APPROACH

Performance increases approx

60% per year

Performance increases approx. 10% per year

Leads to increased complexity and costs

Storage

Storage capacity doubles approx every 24 months, yet performance improvement is near 0

A simple solution, ioMemory

Virtual desktops with ioMemory

Real world VDI density example

HP BL460c gen8, 16 cores,192 GB RAM

with a 1.2 TB IO Accelerator II

Standard office worker, 6 GB space, 1 GB RAM:

+/- 175 desktops per blade

16 x 175 = 2800 desktops

in a 10U chassis

With 3 c7000s over 8.000 super desktops in 1 rack

• Ultimate desktop performance, happy users

• More desktops per server

• Fully separated from other servers and

applications

• Pricing scales linear forever

• Performance scales linear forever

• No expensive upfront SAN costs

• 10x lower power, cooling, space

Business benefits for virtual desktops

Building a high performance & reliable VSAN

VSAN, making the SDDC a reality

Host Host Host

VSAN

VSAN DATASTORE

• Hypervisor embedded Object based storage system

• Flash based r/w cache tier

• Scalable architecture, 3 hosts minimum, No Hardware RAID

• Single VSAN Datastore per cluster

VSAN Requirements

CacheSATA / SAS / PCIe Flash Disks

DataSAS or SATA

7200 rpm Minimum10 / 15K rpm recommended

VSAN VMkernel 1Gb / 10Gb Recommended

VMware ESXi

Storage ControllerPassthrough / NON RAID Mode

Specific HCL for VSAN to cover

• RAID Controllers

• Flash based Disks for cache

• Harddisks for capacity

VSAN Flash layer

CacheSATA / SAS / PCIe Flash Disks

VMware ESXi

• 30% Write Buffer for all writes

• Synchronous Write caching over multiple hosts

• 70% Read Cache for most popular blocks of HDD tier

• Recommended 10-20% of HDD tier
