SAS cabling congurations
The following sections provide the typical supported SAS cabling congurations. Many congurations can
be constructed that are not supported and will either not function correctly or generates errors. To avoid
problems, restrict cabling to only the general types of congurations that are shown in the following
sections.
• “SAS adapter to media expansion drawer” on page 116
• “SAS adapter to expansion drawer combinations” on page 116
• “System external SAS port to disk expansion drawer” on page 117
• “Two RAID SAS adapters with HD connectors to disk expansion drawer in a multi-initiator high
availability (HA) mode (dual storage adapter conguration)” on page 118
