All EVA4400's are configured with dual HSV controllers that operate in a redundant mode. Each
EVA4400 controller has two FC device ports. For EVA4400, in the event of a path failure, the alternate
paths to the controller can be utilized with the use of multi-path software in the Operating System or in
Secure Path software.
On the EVA4400, each port connects to one FC I/O module on a drive enclosure. Up to eight drive
enclosures can be connected in a FC loop arrangement with a controller pair and connect to one port of
up to 96 drives. With the two FC ports per controller, each controller can connect to both ports on up to
96 disk drives for redundant paths to all 96 drives.
The HSV controllers also have dual redundant hot plug power supplies and dual redundant hot plug
blowers. Each controller has hot plug cache batteries to maintain cache contents for up to 96 hours in
case of a total power failure.
The M6412A FC drive enclosure has dual redundant hot plug FC I/O modules that allow the controllers
to distribute I/Os between the two modules and provides redundant paths should either FC I/O module
become unavailable. The enclosure also has dual redundant hot plug power supplies and dual hot plug
blowers. Environmental Monitoring Unit (EMU) functionality is built into the I/O module in the enclosure
and monitors and reports the condition of the power supplies and fans.
The FC and FATA disk drives have dual FC ports which can be redundantly accessed by each controller.
The drives are hot plug. Drives can be configured, using redundant Vraid1 or Vraid5 protection, so that
a drive failure will not cause loss of data. Optional virtual sparing can be configured so that a drive
failure will trigger an automatic rebuild of the Vraid1 or Vraid5 protection using the virtual spare.
All EVAs have dual redundant power distribution. Two independent power cords distribute power through
two Power Distribution Units (PDUs) to each side of the EVA cabinets and to each power supply of the
controllers and to each power supply of the drive enclosures Each cabinet power cord can be connected
to independent power sources. For maximum availability, a customer should provide redundant power
from independent power circuit breakers, independent power lines from the power company and even
independent power companies.

StorageWorks Network Storage Systems allow you to stretch your investment by combining EVA
management, file and print services, and iSCSI connectivity all on the same platform.
The powerful Command View EVA provides an easy mechanism to manage up to 16 EVA units in a SAN
configuration. Industry leading security enhancements in Command View now allows administrators to
take advantage of Windows domains and local groups. Command View integrates with Windows Active
Directory to authorize and authenticate users. In addition, all user actions and events that change system
state are logged. Administrators can now use the audit logging capabilities to provide an audit trail. The
Command View EVA media kits and license are required with all EVA models. HP Command View EVA
requires a License to use (LTUs) equal to, or greater than the total raw capacity of each array.
