2. DRIVERS FOR HIGH-PERFORMANCE STORAGE
Server and Storage Large scale Transaction Digital Media Distribution
Virtualization Processing, Traditional and Web2.0 including On-Demand Streaming
 Increase in randomness of I/Os at the storage device level
 Increase average throughput requirements
 Increase latency and completion time requirements
Big Data Management Multitasking and Business Intelligence
including Metadata, Multitenancy, including Data Warehousing and
Indexing Cloud Computing Data Mining
Storage devices utilizing non-volatile memories are uniquely positioned to close the I/O Gap and deliver these
high-performance storage solutions

3. HITACHI VSP FLASH ACCELERATION RESET
PERFORMANCE EXPECTATIONS
FIRMWARE RE-ENGINEERING RAISES SCALABILITY TO >1,000,000 IOPS
Provide superior value compared to all
flash appliances
 Added performance but not the
cost of a new platform?
 Features but not the additional
staffing to manage them?
 Efficient technology but not a
single–purpose product?

4. HITACHI ACCELERATED FLASH STORAGE
ENTERPRISE FLASH INNOVATION FROM HITACHI
BETTER THAN SLC PERFORMANCE AT BETTER THAN MLC PRICES
 Hitachi Accelerated Flash is the first custom-designed
4X enterprise-class solid state storage option for enterprise
SUSTAINED
PERFORMANCE AND performance, lower cost
workloads, delivering leading
and improved endurance
46% LOWER BIT COST
OVER MLC SSD
The first custom-designed, enterprise-class solid state
storage option for enterprise workloads. Delivers leading
performance, lower cost and improved endurance.

5. HITACHI ACCELERATED FLASH STORAGE
HIGHEST CAPACITY AND EXTENDED ENDURANCE FOR ENTERPRISE WORKLOAD
 New flash storage option for Hitachi Virtual
Storage Platform(VSP)
‒ Complements 10K and NL-SAS HDD
‒ Flash chassis fits in same space as drive
chassis (13U)
‒ New flash chassis is set of 4 x 2U trays, up to
12 x flash module drives each
 Flash module drive (FMD)
‒ Up to 3.2TB
‒ RAID-1, RAID-5, and RAID-6
‒ Single flash enclosure scales from 6.4TB to
153.6TB
‒ Up to 4 flash enclosure per VSP – more than
600TB of flash

6. HITACHI ACCELERATED FLASH
USE CASES AND POSITIONING
 Can you sustain paying a high bit price for your solid state at the rate your
business is growing?
 Can you continue to dedicate solid state capacity to just a few hosts?
 Does it make sense to use solid state caching when your cache hit is going
down due to data growth?
