The EVA supports 300 GB, 450 GB, and 600 GB reduced power 10K rpm dual-ported 4 Gb/s FC and
300GB, 450GB and 600GB 15K rpm dual-ported 4 Gb/s FC disk drives. The minimum number of high
performance fibre channel drives supported on an EVA is 8.
The EVA arrays will support single or mixed drive capacities and types (solid state drives, high
performance and FATA) within an enclosure. HP recommends using the same drive capacity type within a
disk group because virtualization allocates space proportionate to the highest capacity drive within the
group.
FATA Drive Support
FATA Drive SupportFATA Drive Support
FATA Drive Support
The EVA supports 1TB dual ported 4 Gb/s Fibre Attached Technology Adapted (FATA) disk. An EVA will
support a full configuration of FATA disk drives. A minimum of eight FATA drives are required in a
configuration.
FATA drives are designed for lower duty cycle applications such as near on-line data replication for
back-up. These drives should not be used as a replacement for EVA's high performance, standard duty
cycle, Fibre Channel drives. Doing so could shorten the life of the drive.
FATA drives are not recommended in Continuous Access applications as the remote storage location for
local data residing on standard higher speed disk drives. Continuous Access tends to perform fairly high
duty cycle random writes to the remote disk array. Matching remote FATA drives with local FC drives will
impact the performance of your application, and will adversely impact the reliability of the FATA drives.

The EVA6400/8400 takes advantage of the benefits of Fibre Channel (FC) in distance, performance and
connectivity. The use of optical Fibre cabling allows distances between connected segments of a SAN to
be up to 500 meters @ 1 Gb/s; 300 meters @ 2 Gb/s using short wave multi-mode cable and up to 10
kilometers (6.21 miles) @ 1 Gb/s when using long wave cable. The EVA6400/8400 are 4 Gb/s
enabled on each FC path, but will also support 2 Gb/s FC paths for backwards compatibility. Storage
Area Networks (SANs) can be constructed using FC switches/directors for fabric connectivity (currently up
to a maximum of 20 FC switches supported).

Support for up to twenty FC switches operating at 2 Gb/s and 4 Gb/s allow the full benefits of a storage
area network (SAN), providing exceptional connectivity while increasing the effective bandwidth of the
network. Supported SAN features include Zoning for communication isolation and Inter-Switch Links
(hops) up to 10 km. For more information on specific support specifications see the following Switch URL:

The EVA6400/8400 has four FC host interfaces per HSV400/450 controller; eight for a controller pair.
Each controller-to-host interface is 4 Gb/s. The controllers are also compatible with 2 Gb/s, 4 Gb/s and
8 Gb/s FC switches, HBAs, servers and other storage solutions.
Each EVA controller pair interfaces with M6412 drive enclosures through redundant fibre channel
arbitrated loops. With 4 per HSV400 for EVA6400 and 6 per HSV450 for EVA8400 device ports and
dual FC I/O modules per drive enclosure, each controller can connect to each FC drive A and B port via
redundant fibre channel loops. Each controller has a redundant path to each drive.
