IBM United States Hardware Announcement110-009IBM is a registered trademark of International Business Machines Corporation 12The following feature number I/O drawers are available for order on the Power 750.PCI-X DDR 12X Expansion Drawer (#5796)The PCI-X DDR 12X Expansion Drawer (#5796) is a 4 EIA unit tall drawer andmounts in a 19-inch rack. Feature 5796 is 8.8 inches wide and takes up half thewidth of the 4 EIA rack space. Feature 5796 requires the use of a feature 7314drawer-mounting enclosure. The 4 EIA tall enclosure can hold up to two feature5796 drawers mounted side by side in the enclosure. The PCI-DDR 12X ExpansionDrawer has six 64-bit, 3.3 V, PCI-X DDR slots running at 266 MHz that use blind-swap cassettes and support hot plugging of adapter cards. The drawer includesredundant hot-plug power and cooling. The client must select one of the twoavailable interface adapters for use in the feature 5796 drawer, either the Dual-Port12X Channel Attach Adapter -- Long Run (#6457) or the Dual-Port 12X ChannelAttach Adapter Short Run (#6446). The adapter selection is based on how close thehost system or the next I/O drawer in the loop is physically located.A maximum of four feature 5796 drawers can be placed on the same 12X loop.Mixing features 5802 or 5877 and 5796 on the same loop is not supported. Mixingfeature 5796 and the 7314-G30 on the same loop is supported with a maximum offour drawers total per loop. A minimum configuration of two 12X cables (either SDRor DDR) and two ac power cables and two SPCN cables is required to ensure properredundancy. The drawer attaches to the host CEC enclosure with a 12X adapter in aGX slot via 12X SDR or DDR cables.The Power 750 uses GX Dual-port 12X Channel Attach (#5609) or GX Dual- port12X Channel Attach (#5616) to attach a feature 5796 12X I/O Drawer using SDRspeed, no matter which GX adapter is used.PCI-X DDR 12X Expansion Drawer (7314-G30) (supported, not orderable)The 7314-G30 is equivalent to the feature 5796 described above with one keydifference -- IBM i does not support this I/O drawer. Otherwise, it provides the samesix PCI-X DDR slots per unit and has the same configuration rules/considerations asfeature 5796.12X I/O Drawer PCIe, SFF disk (#5802)This feature provides a 4U high 19-inch I/O drawer containing 10 PCIe 8x I/Oadapter slots and 18 SAS hot-swap SFF SAS disk bays, which can be used for eitherdisk drives or SSDs. Using 146 GB disk drives, the feature 5802 provides up to 2.6TB of storage.The 18 disk bays can be organized either into one group of 18 bays (AIX/Linux),two groups of nine slots (AIX/IBM i/Linux), or four groups of four or five bays AIX/Linux). Selecting either one, two, or four groups of drive bays is done with a modeswitch on the drawer.A maximum of two feature 5802 drawers can be placed on the same 12X loop.Mixing feature 5802 and feature 5796 and the 7314-G30 on the same loop is notsupported. Mixing feature 5802 and feature 5877 on the same loop is supportedwith a maximum of two drawers total per loop. The PCIe adapter slots use Gen3 blind-swap cassettes and support hot plugging of adapter cards. A minimumconfiguration of two 12X DDR cables and two ac power cables and two SPCN cablesis required to ensure proper redundancy. 12X SDR cables are not supported. Thedrawer attaches to the host CEC enclosure with a 12X adapter in a GX slot via 12XDDR cables (#1861/#1862/#1864/#1865).The Power 750 uses GX Dual-port 12X Channel Attach (#5609) or GX Dual-port 12XChannel Attach (#5616) to attach a feature 5802 12X I/O Drawer. The feature 5609provides the higher capacity bandwidth (DDR).
