The EVA4400 Starter Kits and EVA4400 have two FC host ports per HSV300 or HSV300-S controller;
four for a controller pair. Each controller-to-host interface is 4 Gb/s. The HSV300 and HSV300-S
controllers are compatible with 2 Gb/s and 4 Gb/s FC switches (if required), HBAs, servers and other
storage solutions.
Each EVA controller pair interfaces with the M6412 drive enclosures. With 2 device ports per controller
and dual FC I/O modules per drive enclosure, each controller has two connections to each FC drive A
and B port. So each controller has a redundant path to each drive.
The EVA4400 can ship from the factory fully configured. After unpacking, it can be plugged into power
sources, connected to the FC SAN, enabled and configured using HP SmartStart for EVA Storage and
Command View EVA and it is ready for use. Installation and start-up services are not required but are
available separately.
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 300 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 M6412 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. The 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.
The EVA4400 with embedded switch model also includes two 10 port 8Gb/s FC SAN B-series switches.
