SAS Connectors Features The sled's SAS expander has four external mini-SAS connectors and four internal mini-SAS connectors. The external mini-SAS connectors support direct cable connection, an external mini-SAS x4 cable (SFF-8088) connects the compute sled's HBA/RAID HBA to the SAS expander. The external miniSAS A1, A2, B1, and B2 connectors connect to all 12 or 24 hard-drives. The internal mini-SAS connectors support hard-drive backplane connection, the hard-drives and SAS expander in the storage sled communicate with each other through the hard-drive backplane. NOTE: When you configure zoning for the sled, the external mini-SAS connectors become zone groups 0, 1, 2, and 3. Zoning allows each compute sled to have access to the hard-drives in an assigned zone. Figure 1-8.
