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 custom-
ers’ shrinking budgets
Poor Value – Pricing initially appears attractive until lack
of flexibility, 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 configured in the same SAN.
Wide variety of RAID levels are simultaneously
supported
Significant flexibility 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
