EXP395 drive enclosure (1814-92H)
The EXP395 drive enclosure (model 1814-92H) is more than
“just a bunch of disks.” The enclosure is designed to optimize
performance, availability and serviceability. It features:

4 Gbps Fibre Channel interfaces for high-speed connectivity

Up to 16 Fibre Channel, SAS or SATA disk drives

An enclosure services manager (ESM)-embedded loop switch

Redundant 4 Gbps Fibre Channel drive loops, which help
ensure availability in the event of a loop or cable failure

Redundant power supplies, cooling fans and ESMs
All primary components are hot-swappable customer-
replaceable units (CRUs) that can be easily accessed
and removed or replaced.
Intermix capabilities
DS3950 Express supports intermixing of Fibre Channel,
FC-SAS and SATA disk drives within the controller. It also
supports attachment of EXP395 and legacy EXP810 enclosures
to further enhance storage utilization.
Scalability throughout the DS3950
Because DS3950 Express is designed to be highly scalable with
up to 112 Fibre Channel, FC-SAS or SATA disk drives, it can
be upgraded from a workgroup SAN to an enterprise network
storage system to grow with your business. In addition, with
IBM System Storage DS® Storage Manager software, you can
combine multiple DS3950 Express systems to help address
additional performance and capacity requirements.
Dynamic capacity expansion (DCE) enables you to add
EXP395 enclosures to an existing DS3950 Express without
stopping operations. This can help you bring unused storage
online for a new host group or an existing volume to provide
additional capacity on demand.
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.
Centralize administration through
DS Storage Manager software
The DS Storage Manager software included with
DS3950 Express supports the centralized management of local
and networked DS3950 systems. The software allows you to
customize and change settings, configure new volumes, define
mappings, handle routine maintenance, and dynamically add
new enclosures and capacity to existing volumes—all without
interrupting user access to data. Failover drivers, performance-
tuning routines and cluster support are also standard features of
DS Storage Manager. In short, this software helps reduce the
complexity of storage management and the amount of time
spent managing storage.
Enhance storage management
capabilities
Using the DS Storage Manager software, administrators can
partition DS3950 Express into as many as 128 virtual servers.
Your IT organization can strategically allocate storage capacity
to achieve high utilization of storage space and help reduce
hardware and storage management costs. Instead of purchasing
multiple RAID controllers with their own dedicated disks and
management, you can attach multiple servers to one central
system—DS3950 Express—which provides hardware failover
with dual controllers and common management.
