Cabling a set of enclosures

Abstract:

Mechanisms are provided for cabling a set of enclosures. Using a set of cables that comprises eight physical layers (PHYs), the set of enclosures are coupled together such that: for a first enclosure and each intermediate enclosure in the set of enclosures, at least four PHYs of the eight PHYs terminate within a Serial Attached Small Computer System Interface (SCSI) (SAS) expander of the first enclosure and a SAS expander of each intermediate enclosure white passing through a remaining four PHYs of the eight PHYs without connecting to the respective SAS expander; and, for a last enclosure in the set of enclosures, all of the eight PHYs terminate in the SAS expander of the last enclosure.
