Find out how to pick the best storage vendor. This presentation covers the best practices for Flash storage, presented by Eric Herzog, CMO & SVP of Alliances, Violin Memory. In this presentation you will learn about * Storage challenges in application deployments * Flash fabric architecture (FFA), including performance, density and resiliency * How a flash fabric architecture revolutionizes the economics in a data center thanks to reduced storage costs, reduced core/servers, reduced software licensing, and reduced power/space/cooling usage. * real-world examples from customers, including a global telcom, a Fortune 500 retailer, Juniper Networks and multiple other customers * examples from customers of increased performance and lowered costs in the datacenter

4. Violin Memory: Revolutionizing Data Center Economics
Delivered a latency of 120 microseconds 8 milliseconds with legacy storage.
“Batch reports that took five hours
now run in 90 minutes.”
“We increased the query capacity of our eDiscovery system by 6x”
Over $1.2 million savings in OPEX/CAPEX.
Video streaming application runs 10Xfaster on Violin flash storage.
Nightly reports reduced by over 7X, down to 50 minutes from 6 hours.
“Achieving up to 800% improvement in VM creation time.”
“With Violin technology the data is ready, waiting for us whenever we need it”
ERP system is running 4X faster on the Violin platform.

5. Flash Fabric Architecture™
Performance
oOver 500K sustained IOPS at sub .5ms latency with mixed, heavy workloads using MLC Flash
oAutomatic Quality of Service
Density
o70TB raw in 3RUs and low power (500W/RU)
Resiliency
oAutomated, transparent GBC in the background without application performance impact
oDesigned for long flash life with array- wide flash management, wear leveling and vRAID

6. Write Cliff Affects All Flash Solutions To Some Degree
oNew Write operations get queued behind Erase operations
oUp to 60% performance drop
oReal issue is that Erase operations also get in the way of Read operations
oMitigating or eliminating the Write Cliff requires special flash management logic

7. Patented Algorithms Deliver Spike-Free Low Latency
oBackground garbage collection ensures free pages for all incoming writes
oGarbage collection implemented in hardware within each VIMM for line rate performance
oGarbage collection tightly scheduled & orchestrated at the system level to not affect system performance
oGarbage collection allowed one VIMM per Protection Group at a time

“Forward-thinking CIOs use flash to lower their costs, but there are still many who hesitate to try the technology. Many argue that they can't afford the huge gap between flash and HDD price per gigabyte, but they lose sight of the fact that the system's capital and operating costs both dramatically drop once flash is applied.”
