a: The LSI SAS3108 supports two types of RAID keys, which support 32 and 240 drives respectively. For details, see Table 6-4 Supported RAID levels and quantity of drives in RAID 0, 1, 5, 6, 10, 50, and 60. b: The Avago SAS3508 supports two types of RAID keys, which support 32 and 240 drives respectively. For details, see Table 7-2 Supported RAID levels and quantity of drives in RAID 0, 1, 5, 6, 10, 50, and 60. c: The LSI SAS3108 PCB version .B and later support out-of-band management. The LSI SAS3108 PCB version .A does not support out-of-band management. d: Maximum number of drives in all RAID arrays (for an LSI SAS3008IR RAID controller card) = Number of hot spare drives + Number of drives in RAID arrays. Maximum number of drives in all RAID arrays (for other RAID controller cards) = Number of hot spare drives + Number of idle drives (drives in Unconfigured Good state) + Number of drives in RAID arrays. e: RAID 0 is excluded. f: To obtain the code of the RAID controller card that supports the CacheCade, use the Computing Product Compatibility Checker. |
