Storage System Hardware
You can use any existing FDDI, multimode, 62.5 micron cable with good connections to attach servers, switches or hubs, and storage systems. These cables must be dedicated to storage-system I/O.Table 5- 3 Cable Sizes — Optical
Length Typical Use
5 m (16.5 ft) or
10 m (33 ft)
Within one room, connecting servers to storage systems (adapter
must support optical cable) or connecting switches or hubs to storage
systems
50 m (164 ft) Within one building, connecting servers to storage systems (adapter
must support optical cable) or connecting switches or hubs to storage
systems
100 m (328 ft) Within one complex, connecting servers to storage systems (adapter
must support optical cable) or connecting switches or hubs to storage
systems
250 m (821 ft,.15 mi)
500 m (1642 ft,.31 mi)
Optical cabling is 50 micron (maximum length is 500 m —1,650 ft —, or
62.5 micron (maximum length is 300 m — 985 ft. Both types are multimode, dual SC, and require a MIA on
a DB-9 or hub connector. The minimum length is 2 m (6.8 ft). The minimum bend radius is 3 cm (1.2 in).
