Changing the economics of flash storage Delivering flash at the price of disk

Mike Davis Director of Marketing SNIA DSI Conference April 21, 2014

Virtualizat ion is increasing the demand for random I/O with the “mixer effect”

Flash economics are driving rapid adoption Pent- up demand for improving application performance at the right price point Flash prices falling faster than HDDs but st ill

considerably higher than 15K HDDs

15K HDD

$/G

B Flash SSD

7.2K HDD

New form factors: PCIe cards, appliances, shared storage

Mult i- core processors drive up processor ut ilizat ion and demand for more I/O per server, while HDD throughput remains flat

2

Reliance on I/O-intensive solut ions for critical applications is growing

IT Managers are looking for storage solut ions that can span both, hot and cold data, opt imizing for performance and value

Server- based cache

Indexing • Maintains indexes to

allow quicker access to data

• Runs on databases to accelerate locating a block o f data in queries

Data Warehousing • Sto red data used to

create reports o r derive Business Inte lligence

• Used fo r data m ining, analysis, hypo thesis testing, m odeling

OLTP • Manage transaction-

• Business can be hurt if data no t accessible ,slow

• During peak usage , custom er experience can be effec ted

VDI • Hosting desktop OS

• Facilitate a quick re trieval o f go ld im ages

• Boot sto rm s, write allocations and latency are issues

“We’re successfully m itigating boo t sto rm s as well as load sto rm s when a lo t o f people are logging into the ir virtual desktops at once . You’d be surprised how m any IOPS it takes to log in—it’s one o f the m ajo r challenges with large- scale VDI.” Luther Bo wens, System s and Operatio ns Manager Indianapo lis Public Scho o ls

• Application perfo rm ance sem antics: Concurrent users, TPS

• Sto rage perfo rm ance sem antics: throughput, IOPS, perfo rm ance per GB, File perfo rm ance

What characterizes your workloads? Traditional “one size fits all” data sto rage strategy is unrealistic

Each type of data needs to be treated different ly to align the applicat ion performance with capacity and cost requirements
