Server-side caching (with Flash) accelerates Hyper-V FlashSoft Software

The Root of the Problem: I/O Latency
server performance
storage performance
Processor to I/O performance gap aka “the I/O bottleneck”
How Enterprise IT Address Storage Performance
Overprovision capacity to reach performance goals
Faster switches, HBAs, cables – expensive and disruptive
Expensive all-flash arrays or disruptive locally attached Flash
Lots and lots (and lots) of disk

Upgrade the SAN Throw Flash at it
Evolving Role of Flash in the Datacenter

• Add Flash to your Array
• Add an All-Flash Array
• Add Flash to server as Primary Storage
• Add Flash to server for caching
“Many possible locations for flash; none of which are mutually exclusive”
Why Customers Choose Server Side Caching
Removes the storage latency that constrains performance of applications and virtualized servers

Least disruptive means of introducing flash for improved performance – even between data center refreshes
Easy to evaluate, runs automatically with no administrative overhead, and is very economical to purchase and deploy
Reduces overall storage spending by putting flash precisely where needed, instead of replacing all HDD with SSD
FlashSoft® Software " Host-Based, Solid-State Caching
§ Software solution § Platform-independent caching engine § Any PCIe or SAS SSD, from any vendor § Write-back cache (single node) § Write-through cache (Hyper-V cluster) § Scalable: 100’s of volumes or VMs
" Resource Efficient § Server resource efficiency: 500MB § CPU utilization: 2%-4%
" “Bare Metal” Server Acceleration § Databases: OLTP performance 3x-5x § OLAP batch processes 4x – 5x faster § Enterprise apps: 3x concurrent users
" Hyper-visor Acceleration § App performance 3x-5x faster § VM density 3x greater § No code running in the VM
" Compatibility § Transparent to applications and OS § No changes to underlying storage – DAS or SAN

Caching
SAN
• Virtual Machines are assigned to a CSV on shared storage
• A copy of frequently read data is cached on the local SSD
• Writes go straight to SAN (with a copy to the cache)
• Next read is faster • Next read after right is faster
² Application runs faster ² Storage has lower load since so
many reads happen in the server

Caching
SAN
• The VM moves to another server • Data is still available on the CSV
(write-through cache) • Caching starts automatically on
the new server • Cache on original machine is
cleared to ensure data integrity when the VM returns
