Backup and Restore option—Allows 512 Enhanced
FlashCopy images on the DS3500 system; Enhanced
FlashCopy technology delivers easier setup of shared versus
dedicated repositories and reduces capacity requirements and
copy-on-write capacity consumption

Performance Read Cache option—Utilizes SSDs as a level-
two data cache, significantly improving read performance
from spinning media; Performance Read Cache is extremely
easy to set up and, once implemented, it automatically identi-
fies the data that is read most frequently and copies it into
cache for fast access

Super Key option—Combines all of the features into one
single key for easy deployment and management
Supports VMware and heterogeneous
operating systems
The DCS3500 Express offers the scalability, availability and
integration necessary to power VMware implementations of all
sizes. Its heterogeneous operating system support provides flex-
ibility to manage a wide range of storage needs. It also includes
support for VMware vSphere application programming inter-
face (API) for Array Integration. And two application-aware
plug-ins enable vCenter and Storage Replication Adapter (SRA)
for efficient management.
Enables energy-saving implementations
With rising energy expenses and IT space constraints, efforts
to reduce power consumption in a small IT footprint have
quickly come to the forefront as hot-button IT issues for many
organizations. To respond to these challenges, IBM has made
great strides in energy-efficient implementations with the
DS3500 Express, which introduces power-saving features
designed to have virtually no impact on performance, scalability
or functionality.
Smaller form-factor 2.5-inch SAS drives, one of multiple drives
supported by the DS3500 Express, provide up to three times
more IOPS per watt in power consumption than 3.5-inch
drives and enable twice as many drives to reside in the same
2U of rack space. These drives also deliver impressive IOPS
performance in a small form factor with minimal impact on
power consumption or heat dissipation.
Energy-efficient power supplies help ensure just that—energy
efficiency. By efficiently converting AC power from electric
utilities into DC power used by the storage system, the DS3500
Express power supplies ensure that overall annual expenditures
are lower than other, less-efficient implementations. And with
low heat dissipation, the DS3500 Express serves a key role in an
overall energy-saving and green solution.
With a DC-powered model for 24-drive enclosures with
NEBS and ETSI compliance, the DS3500 Express offers sav-
ings in energy expenses, meets standard telecommunications
requirements and minimizes risk in harsh environments.
The DS3500 Express continues the tradition of superior disk
use that enables users to achieve maximum return on invest-
ment (ROI) on their storage investments. The DS series can
deliver up to two times the disk use of leading competitors,
enabling organizations to achieve maximum performance with
fewer drives and less energy consumption.
