5. Drivers for High-Performance Storage

6. FLASH USE CASES
SUPPORTS APPLICATIONS THAT REQUIRE “RANDOM” WORKLOADS
File Shares
(unstructured)
SQL Server
Database
Analytics Apps
(Unix/Linux)
VMware/VDI
environments
Oracle Database
(Red Hat/OVM)
VMFS
OCFS/GFS
File System
NFS/CIFS
CSV/NTFS
GPFS/GFS
HDFS/JFFS
 All of the above applications generate high random read/write IO and require low
latency.
 Match use cases to flash implementations to deliver on performance promises at
lowest possible overall system cost

7. WHY ARE RANDOM IOPS
WORKLOADS CRITICAL?
 I/O workloads are either random (many concurrent accesses to
relatively small blocks of data) or streaming (sequential data
transfers)
 Historically, random access has been associated with
transactional workloads, which often represent an enterprise’s
most critical IT operations
 Adoption of “scale-out” architectures with networked storage −
drivers for scale-out include server and desktop virtualization,
database consolidation, complex analytics, and data
warehousing
 Even workloads that appear to be sequential from an individual
application’s point of view actually become random as they
interact with other workloads using advanced disk array
capabilities like de-clustered RAID, thin provisioning, and
automatic storage tiering

8. FUNDAMENTAL STORAGE PERFORMANCE
CHANGES AVAILABLE
Yesterday’s High Performance
Today’s High Performance
A single Hitachi Accelerated Flash storage
module can deliver 500X more IOPS than a
single high-performance disk drive

11. FLEXIBILITY FOR APPLICATIONS
Adopting an “ALL-IN-ONE” enterprise storage platform provides
 Hitachi flash acceleration
‒
Firmware that has been re-engineered to increase scalability for host I/O processing on
exiting VSP and HUS VM
‒
Can also be implemented without the need of SSD or Hitachi Accelerated Flash; however,
adding either of these will provide performance improvements
 Hitachi Accelerated Flash (HAF)
‒ The HDS flash memory controller (HAF) is a multi-core, high-bandwidth architecture that
uses block and page mapping, wear leveling, an endurance manager, and inline write
compression that results in up to 94% write reduction
‒ Hitachi custom designed and built
 Hitachi Dynamic Tiering (HDT) hybrid storage
‒
‒
Utilize automated sub-LUN dynamic tiering for pooling storage resources for application
host access
Thin provisioning capability for efficient storage utilization and better performance
 Storage virtualization
‒
Virtualize up to 100+ external storage arrays and obtain the benefits of preserving existing
assets, migration, and/or consolidation for management

12. HITACHI INNOVATION: FLASH ACCELERATION
SOFTWARE REENGINEERING TO EXPLOIT FLASH CAPABILITIES
 30+ fundamental software changes to
turbo-charge performance with flash
‒ New “express” I/O processing
Hitachi Storage
‒ Higher internal thread count support
‒ Improved wide striping capability
 Significant performance impacts
‒ Up to 65% reduction in response time
‒ Up to 2X Hitachi Dynamic Provisioning
