Double the Performance of
Disk-Based Systems
HUS VM all flash system doubles
the performance of hard disk-based
systems and dramatically lowers
response times. This system employs
newly patented flash-optimized
software and Hitachi Accelerated
Flash storage which deliver 500,000
IOPS, sub-millisecond response
time with consistent performance.
Compared to the commodity solid-state
drives found in competitive systems,
the flash memory design that Hitachi
developed for Hitachi Accelerated
Flash storage provides better perfor-
mance, durability and capacity. Hitachi
Accelerated Flash storage speeds IO
processing to increase flash device
throughput. It delivers faster access
to data for virtual desktop and e-com-
merce applications. And it accelerates
database, online transaction and ana-
lytic processing (OLTP and OLAP) and
messaging infrastructure performance.
Dramatically Improve
Storage Economics
By doubling the performance of disk-
based systems, HUS VM all flash
system eliminates the need to over-
buy and overarchitect to meet the
requirements of high-performance
applications. HUS VM all flash system
also delivers a 60% better cost per
I/O than similar solid state drive-based
systems, and it does so in less space.
While the cost per I/O makes flash
a logical choice for many organiza-
tions, maximizing the benefits of your
flash purchase is critical for the best
return on investment. With Hitachi
Dynamic Tiering and thin provision-
ing, you can allocate more bandwidth
than you use in flash and copy, with-
out incurring capacity overhead. To
achieve even greater flash efficiency,
you can add file deduplication to
your organization’s unified system.
As the only all flash array with external
storage virtualization capability, you can
add HUS VM all flash into an overtaxed
environment of older HDS or 3rd party
storage and see immediate manage-
ment and utilization benefits. Support
for tiering to external storage enables
companies to ensure their most impor-
tant data sits in new flash capacity and
extends the life of existing assets.
Boost Storage and
Management Efficiency and
Flexibility
In addition to improving performance
and economics, HUS VM all flash
system boosts storage efficiency
by consolidating all data types in a
high-performance, unified system.
The all flash system doubles the den-
sity of the solid state-drive-based
HUS VM, in the same rack space.
To boost management efficiency, HUS
VM all flash system is supported by
Hitachi Command Suite, which auto-
mates and simplifies management
tasks for HDS solutions. This means
administrators won’t have to learn a
