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 PS4X00 Series
DS3500 Advantages
EqualLogic PS4X00 Disadvantages
Affordable
– Fits most entry to small
midrange customers’ 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

* Dual controller configurations require identical host interface cards for each controller
**A second ESM must be added to expansion units behind a DS3500 with dual controllers
NOTE: 3.5-in drives can only reside in the EXP3512 and 2.5-in drives can only reside in the EXP3524
