Fi bre Optic Fibr
e Channel cables
The Enterprise Virtual Array uses orange, 50-µm, multi-mode, ber optic cables for connection to the
SAN. The ber optic cable assembly consists of two, 2–m ber optic strands and small form-factor
connectors on e
ach end. See Figure 13.
To ensure o ptim
um operation, the ber optic cable components require protection from contamination
and mechanical hazards. Failure to provide this protection can cause degraded operation. Observe the
following precautions when using ber optic cables.
To avoid breaking the ber within the cable:
•Donotkinkth
ecable
Do not use a cable bend-radius of less than 30 mm (1.18 in)
To avoid deforming, or possibly breaking the ber within the cable, do not place heavy objects
on the cable
.
To avoid contaminating the optical connectors:
Do not touch the connectors
•Neverleave
the connectors exposed to the air
Install a d ust cover on each transceiver and ber cable connector when they a re disconnected
If an open connector is exposed to dust, or there is any doubt about the cleanliness of the connector,
clean the c
onnector as described in Handling ber optic cables.

Copper Fibre Channel cables
The Enterprise Virtual Array Fibre Channel 100 00 - Series implementation uses copper Fibre Channel
cables to
connect the drive enclosures to e ach other, or to the loop switches a nd to the HSV controllers.
The cables are available in 0.6–meter and 2.0–meter lengths. Copper cables p rovide performance
comparable to ber optic cables. Copper cable connectors differ from ber optic small form-factor
connectors (see Figure 14).

Fibre Channel disk drives
The Fibre Channel disk drives are hot-pluggable and include the following features:
Dual-ported 2–Gbps Fibre Channel drive enclosure interface that allows up to 120 disk drives to
be supported per Fibre Channel drive enclosure pair.
Compact, direct-connect design for m aximum storage density and increased reliability and
signal integrity.
