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. The expansion enclosures support single I/O path and dual I/O path connectivity topology. For single I/O path configurations, each port on the adapter can be connected to a separate chain of expansion enclosures by using the ESM A in each connected enclosure. For dual I/O path configurations, each port on the 2-port RAID adapter or HBA is connected to a different ESM chain within the same chain of enclosures. For specific configuration limits, refer to SAS RAID controllers and HBAs . For SAS RAID controllers, the controller’s firmware manages multiple I/O paths from the controller to SAS drives. For SAS HBAs, the host operating system runs multi-pathing software to manage multiple I/O paths. 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. In addition, up to two D1212 and up to two D3284 drive enclosures, or one D1224 and up to two D3284 drive enclosures can be daisy-chained with support for up to two hosts attached to the chain.

The following figures illustrate different host connectivity topologies.

Figure 5. Connectivity topology with one host

Figure 6. Connectivity topology with two hosts

Figure 7. Connectivity topology with four hosts

Configuration notes:
Attachment of more than one host to the same enclosure without SAS zoning is supported with HBAs only (RAID controllers are not supported). While all attached hosts are capable of accessing all drives in the enclosures, the clustering software running on the hosts controls which cluster nodes have access to the drives at any given time. With SAS zoning enabled, only standalone enclosures without daisy-chaining can be partitioned for multiple host access. Expansion ports are not supported when zoning is enabled
