Installing SAS Cables

The cabling from the host to the ESMs in the drive module uses a “top-down” cabling
scheme. In a top-down cabling scheme, the SAS cables connect from the host to the ESMs
in the drive module closest to the host. In turn each additional ESM connects to another
ESM in the next drive module. Different lengths of SAS cables are not required for top-
down cabling. Note that you can connect the drive module to the standard SAS
connection on the SGI host system. This may affect performance and data transfer rates,
depending on the number of drives installed in the module.

Connect the SAS cables from the rear of the storage array.

shows an example of

the SAS cables connected from a dual-SAS PCI card in the host to the ESMs in the drive
module.
