2.10.2 EXP24S SFF Gen2-bay drawer
The EXP24S SFF Gen2-bay drawer (FC 5887) is an expansion drawer supporting up to 24
hot-swap 2.5-inch SFF SAS HDDs on POWER6, POWER6+, POWER7, or POWER7+
servers in 2U of 19-inch rack space.
The SFF bays of the EXP24S drawer differ from the SFF bays of the POWER7 or POWER7+
system units or of the 12X PCIe I/O Drawers (FC 5802 or FC 5803). The EXP24S uses Gen2
or SFF-2 SAS drives that physically do not fit in the Gen1 or SFF-1 bays of the POWER7 or
POWER7+ system unit or of the 12X PCIe I/O Drawers, or vice versa.
The drawer can be attached to the Power 720 and Power 740 either using the FC EJ01
storage backplane, providing an external SAS port, or using the following PCIe SAS adapters
or pair of adapters:
򐂰 PCIe LP Dual-x4-Port SAS adapter 3 Gb (FC 5278, CCIN 57B3)
򐂰 PCIe 380 MB Cache Dual - x4 3 Gb SAS RAID adapter (FC 5805, CCIN 574E)
򐂰 PCIe Dual-x4 SAS adapter 3 Gb (FC 5901, CCIN 57B3)
򐂰 PCIe 380 MB Cache Dual - x4 3 Gb SAS RAID adapter (FC 5903, CCIN 574E)
򐂰 PCI-X 1.5 GB Cache SAS RAID adapter 3 Gb (FC 5908)
򐂰 PCIe2 1.8 GB Cache RAID SAS adapter Tri-Port 6 Gb (FC 5913, CCIN 57B5)
򐂰 PCIe2 RAID SAS adapter Dual-Port 6 Gb (FC ESA1, CCIN 57B4)
򐂰 PCIe2 LP RAID SAS adapter Dual-Port 6 Gb (FC ESA2, CCIN 57B4)
