Drive-side trunking cabling configurations

The following notes describe information about drive-side trunking that you must
consider.
v Drive-side trunking is supported only with the EXP5060 storage expansion
v Connect the EXP5060 and EXP5000/EXP810 storage expansion enclosures in
v Intermixing enclosures with trunked and standard cabling in the same storage
v Benefits are that drive-side trunking doubles the number of fibre connections,
Use the cabling configuration examples in this section as a guide to configure your
storage array to receive the benefits of drive-side trunking. Drive-side trunking
requires that the ESMs have four ports to support trunked cascading connections to
other storage expansion enclosures. These cascading connections only apply when
eight storage expansion enclosures are connected to the storage subsystem.
