IBM System Storage™ DS3500 Express
Offers substantial performance and functionality starting at entry-level prices
Building the DS3500
START with the DS3500 // Four 6 Gbps SAS host connectors in a dual controller configuration
• Cost-effective high performance storage for up to two direct-attached servers in a Highly Available conguration
• Connectivity to redundant 16-port SAS switches supports up to eight servers in a Highly Available conguration
• Provides booting and shared storage for IBM BladeCenter®
DS3524 – Best t for environments requiring highest performance, best price/performance, or lowest power/cooling
DS3512 – Best t for environments requiring highest capacity, or a high capacity/high performance blend
Add a host card to expand SAS connectivity or support additional interface technology
SAS host card – adds two more 6 Gbps SAS host connectors per controller
• Further expands shared DAS or networked capabilities with support for eight SAS connectors (dual controller)

Competitive Overview – DS3500 Express versus:
HP P2000 G3
IBM DS3500 Advantages HP P2000 G3 Disadvantages
Provides a common management interface – minimal
learning curve across the DS5000, DS4000, DS3500
and DCS3700
No continuity across the HP storage platforms – each
array family must be learned
The DS3500 supports self-encrypting drives (SEDs)
SAS drives for securing data-at-rest
The P2000 G3 does not have any security solutions for
data-at-rest
EqualLogic
IBM DS3500 Advantages EqualLogic PS4X00 Disadvantages
Affordable – Fits most entry to small midrange customers’ shrinking budgets
Poor Value – Pricing initially appears attractive until lack
of exibility, expansion and much more is detected
Offers a range of host interface options and intermix –
SAS, iSCSI + SAS, or FC + SAS
Extremely limited host connectivity with only two iSCSI
ports
Scalability can be achieved in a cost-effective manner
by adding EXP3512 and/or EXP3524 expansion units
Scalability becomes expensive. Expansion enclosures
are not offered. A total of only two PS4000s or two
PS4100s may be congured in the same SAN.
Wide variety of RAID levels are simultaneously
supported
Signicant exibility restrictions. Only one drive type,
drive size, drive speed and RAID level per node
HP P4000 SAN Solution (Lefthand Networks)
IBM DS3500 Advantages HP P4000 Disadvantages
Competitively priced to meet restrictive budgets Pricing not within most entry-level customer budgets
and high preset drive quantities
Offers a range of host interface options and intermix –
SAS, iSCSI and SAS, or FC and SAS
Limited host interface choice with only FC and iSCSI
No incremental software costs for expansion Expansion is expensive - each expansion node requires
repurchasing of “bundled” software
A single dual controller DS3500 can provide high
availability
An additional P4000 is required to achieve redundancy
and availability
