DS3950 Express

Manage growth, complexity and risk with

scalable, high-performance storage

Highlights



Simplify storage infrastructure with

8 Gbps Fibre Channel interfaces



Leverage mixed-host interfaces support

(Fibre Channel and iSCSI) for storage

area network (SAN) tiering



Gain balanced performance well-suited

for virtualization and consolidation



Support for intermixing Fibre Channel,

SATA and FC-SAS drives enabling

cost-effective tiered storage



Support up to 112 disk drive modules

using up to six IBM® System Storage®

EXP395 expansion units

Optimized data management requires storage solutions with high

data availability, strong storage management capabilities and powerful

performance features. IBM System Storage DS3950 Express is designed

to provide lower total cost of ownership, high performance, robust

functionality and unparalleled ease of use. As part of the IBM DS series,

DS3950 Express offers:



High-performance 8 Gbps Fibre Channel connections



The option of a 1 Gbps iSCSI interface in Model 98H



Up to 224 TB of raw physical capacity using 112 SATA 3.5-inch

(2 TB) disk drives



Powerful system management, data management and data

protection features

Achieve a lower total cost of ownership

Facing relentless data growth and shrinking budgets, companies continue

to look for ways to reduce costs through efficiencies. The advent of

8 Gbps Fibre Channel allows companies to reduce the number of host

bus adapters (HBAs) per server and the number of overall ports in their

Fibre Channel SAN infrastructure without sacrificing performance, thus

saving on both acquisition and operational costs.

IBM Systems and Technology Data Sheet IBM System Storage Increase performance In the same way organizations have benefited from tiered storage (using high-performance Fibre Channel drives for primary storage and low-cost SATA drives for secondary storage), they can now benefit from tiered SANs. IBM DS series storage systems offer high-performance, highly reliable Fibre Channel interfaces for production servers, and low-cost iSCSI interfaces for secondary servers (model 98H).

IBM Systems and Technology Data Sheet IBM System Storage EXP395 drive enclosure (1814-92H) DS3950 Express supports online controller firmware upgrades to help provide better performance and functionality. Events such as upgrades to support the latest version of DS Storage Manager or to add optional services such as DS Remote Support Manager can often be executed without stopping operations. The EXP395 drive enclosure (model 1814-92H) is more than “just a bunch of disks.
