Why This Matters Storage performance can be a limiting factor in database and virtual environments

A hybrid four-node Virtual SAN cluster with SanDisk SSDs delivered 1,702,776 new orders per minute

An all-flash four-node Virtual SAN cluster with SanDisk SSDs delivered 2,542,760 new orders per minute

The all-flash configuration delivered 49% better performance and 26% better price/performance

Higher performance means less hardware, saving on power, cooling and application software licensing© 2016 by The Enterprise Strategy Group, Inc.

Virtual SAN Architecture

• Minimum of 3 hosts in a cluster configuration or 2 hosts + witness

• All 3 host must contribute storage

• Recommended that hosts are configured with similar hardware

• Hosts: Scales up to 64

• Disks: Locally attached storageo Hybrid: Magnetic disks and flash deviceso All-Flash: Flash devices only

• Networko 1GB Ethernet ORo 10GB Ethernet (preferred)

• “Witness” component (only metadata) acts as tie-breaker during availability decisionsesxi-01 esxi-02 esxi-03

99.9999%Availability

• With FTT=2 VSAN delivers 6x9s protection less than 32 seconds of downtime/year

• Typical hardware components provides about 2x9s availability level (3.65 days downtime/year)

• Virtual SAN exponentially increases the availability through mirroring across the cluster

• With default availability policy, Virtual SAN delivers 5x9s protection less than 5 minutes of downtime/year

• Assign level of availability on a per-VM basis and adjust on the fly

Oregon State University: High Performance for VDI with Budget-friendly Scaling

Corvallis, OregonAcademic Institution 26,000 students

Challenge• Storage overburdened by VDI workloads

• User login took over 20 minutes during peak times

• Recomposing VDI environment took 10+ hours

• Limited storage budget

Solution

• Virtual SAN on industry standard x86 servers

Results

• Drastically better performance: user login time reduced from 20 minutes to 1 minute

• Increased VDI scale: support 170+ additional users on existing servers/network

• Simplified management: resetting desktops reduced from 10 hours to <2 hours

• Lower cost and ease of scale: lowered acquisition costs by 75% and enabled easier scaling for future needs
