Delivering solid input/output operations per second (IOPS)
and throughput, the DS3500’s controllers continue IBM’s
tradition of balanced and sustainable performance. The
DS3500 can effectively double the performance of the
current DS3000 series of storage systems in both throughput
and IOPS. With up to 4,000 MegaBytes per second (MBps)
and 40,000 IOPs in sustained drive reads, the DS3500 is
equally adept at delivering throughput to bandwidth-
intensive applications and IOPs to databases and Exchange.

And with support up to 96 drives, scalability has doubled
from the previous-generation systems. By dynamically adding
drive enclosures (up to seven EXP3512, four EXP3524
expansion enclosures or a mix of the two) with virtually no
downtime, you can quickly and seamlessly respond to
growing capacity demands. This scalability also improves
overall system performance by distributing the server’s
input/output (I/O) requests across a greater number of drives.

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 organisations. To respond to these challenges, IBM has
made great strides in energy efficient implementations with
the DS3500 by introducing new power saving features that
do not impact performance, scalability, or functionality.

Smaller form-factor 2.5-inch SAS drives, one of multiple
drives supported by the DS3500, provide up to three times
the 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. 2.5-inch drives also deliver impressive IOPs
performance in a small form-factor (SFF) with minimal
impact on IBM power consumption or heat dissipation.

Energy-efficient power supplies ensure just that – energy
efficiency. By efficiently converting AC power from 
electric utilities into DC power used by the storage 
system, the DS3500 power supplies ensure that overall 
annual expenditures are lower than other less efficient
implementations. And with low heat dissipation, the DS3500
can become a key component of an overall energy-saving and
green solution.

The DS3500 continues in the tradition of superior disk
utilisation that enables IBM customers to achieve maximum
return on investment (ROI) on their storage investment. 
The DS series can deliver almost up to two times the disk
utilisation of leading competitors allowing organisations to
achieve maximum performance with fewer drives and less
energy consumption.

Blending the ease of use and intuitive nature of the
DS3000 Storage Manager as well as the robustness and
functionality previously only available on the DS5000 and
DS4000, the new DS Storage Manager for the DS3500
delivers a simple storage management interface that 
provides great control while maintaining its simplicity.
