36 IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction
To attach a 7216 Multi-Media Enclosure to the Power 770 and Power 780, consider the
following cabling procedures:
Attachment by an SAS adapter
A PCIe Dual-X4 SAS adapter (FC 5901) or a PCIe LP 2-x4-port SAS Adapter 3 Gb (FC
5278) must be installed in the Power 770 and Power 780 server to attach to a 7216 Model
1U2 Multi-Media Storage Enclosure. Attaching a 7216 to a Power 770 and Power 780
through the integrated SAS adapter is not supported.
For each SAS tape drive and DVD-RAM drive feature installed in the 7216, the appropriate
external SAS cable will be included.
An optional Quad External SAS cable is available by specifying (FC 5544) with each 7216
order. The Quad External Cable allows up to four 7216 SAS tape or DVD-RAM features to
attach to a single System SAS adapter.
Up to two 7216 storage enclosure SAS features can be attached per PCIe Dual-X4 SAS
adapter (FC 5901) or the PCIe LP 2-x4-port SAS Adapter 3 Gb (FC 5278).
Attachment by a USB adapter
The Removable RDX HDD Docking Station features on 7216 only support the USB cable
that is provided as part of the feature code. Additional USB hubs, add-on USB cables, or
USB cable extenders are not supported.
For each RDX Docking Station feature installed in the 7216, the appropriate external USB
cable will be included. The 7216 RDX Docking Station feature can be connected to the
external, integrated USB ports on the Power 770 and Power 780 or to the USB ports on
4-Port USB PCI Express Adapter (FC 2728).
The 7216 DAT320 USB tape drive or RDX Docking Station features can be connected to
the external, integrated USB ports on the Power 770 and Power 780.
The two drive slots of the 7216 enclosure can hold the following drive combinations:
One tape drive (DAT160 SAS or LTO Ultrium 5 Half-High SAS) with second bay empty
Two tape drives (DAT160 SAS or LTO Ultrium 5 Half-High SAS) in any combination
One tape drive (DAT160 SAS or LTO Ultrium 5 Half-High SAS) and one DVD-RAM SAS
drive sled with one or two DVD-RAM SAS drives
Up to four DVD-RAM drives
One tape drive (DAT160 SAS or LTO Ultrium 5 Half-High SAS) in one bay, and one RDX
Removable HDD Docking Station in the other drive bay
One RDX Removable HDD Docking Station and one DVD-RAM SAS drive sled with one
or two DVD-RAM SAS drives in the bay on the right
Two RDX Removable HDD Docking Stations
