Host connectivity

The D1212 and D1224 drive enclosures support dual environmental service module (ESM) configurations.
Each ESM has three 12 Gb SAS x4 ports (Mini-SAS HD SFF-8644 connectors) labeled A, B, and C. These
ports are used for connections to a supported RAID adapter or HBA installed in a server and for daisy
chaining the D1212 and D1224 enclosures between each other.
Port A on each ESM is used for connecting the external SAS ports on the RAID controller or HBA to the
enclosure, or for connecting Port C on each ESM in the adjacent enclosure for daisy chaining.
Port B on each ESM is used for connecting the external SAS ports on the RAID controller or HBA to the
enclosure. Daisy-chaining does not use Port B for connections between adjacent enclosures.
Port C on each ESM is used for connecting the external SAS ports on the RAID controller or HBA to the
enclosure, or for connecting Port A on each ESM in the adjacent enclosure for daisy chaining.
Up to eight D1212 or D1224 drive enclosures, or a combination of both, can be daisy-chained with
support for up to four hosts attached to the chain. Without daisy-chaining, a standalone
D1224 drive enclosure can support up to six directly attached hosts.
