Topology and Array Planning Basic Topology The basic topology covers a number of physical implementations of host systems and disk arrays. In general, the following hardware components are used: • One or two host systems • One Fibre Channel I/O adapter for each implementation of the basic topology in each server, with • Up to nine adapters in each K -Class server; The maximum number depends on the number of HSC slots available in each K -Class server (refer to the Configuration Guide for additional details) • Up to three adapters installed in any slots including the Turbo EISA slot in each D-Class model D350, D360, D370 and D380 server; Up to two adapters installed in any slots in all other models of D-Class server; • Up to 22 adapters in each T-Class T600 server • See your Hewlett-Packard support representative for the number of adapters supported in each model of V-Class server • One or two dual-controller module disk arrays (for high availability) or One to four single-controller module disk arrays (for non-high availability) • Maximum 500 m fibre optic cable distance between each host-to-disk array connection • Each implementation of the basic topology uses one Fibre Channel I/O adapter. Each adapter connects to one controller module over an independent two-node Fibre Channel-AL. For example, if one disk array with two controller modules connects to one host with two Fibre Channel adapters, two separate two-node Fibre Channel-ALs are created. Up to 22 instances of the basic topology can be implemented on T-Class servers because up to 22 adapters can be installed in each T-Class system. Supported cable lengths for each host-to-disk array connection include 2 m, 16 m, 50 m, 100 m, and 500 m. Fibre optic cables in lengths of 2 m, 16 m, 50 m, and 100 m can be ordered from Hewlett-Packard (see the chapter 8 for part numbers). Fibre optic cables longer than 100 m must be custom-fabricated for each implementation. Non-high availability and high availability versions of this topology can be implemented depending on whether one or two controller modules are installed in each disk array. Topologies for HP-UX 103
