Device adapter pair IDs – Models 986, 86E (three-phase power)
Device adapter pair IDs identify either the two device adapter cards in an I/O enclosure, or a pair of storage enclosure RAID controllers.
- For FC-AL storage enclosures
- A device adapter pair ID identifies the two device adapter cards in the I/O enclosures. The device adapter cards provide redundancy for the FC-AL loops that connect to one or more storage enclosure pairs.
- For high-performance flash enclosures
- A device adapter pair ID identifies the pair of storage enclosure RAID controllers and their associated interfaces to the I/O enclosures.
Note: For all-flash systems, see Figure 3.
