18 RS/6000 7025 Model F80 Technical Overview
F80. For further information about adapters, especially if the adapter is supported
in Model F80, refer to the
PCI Adapter Placement Reference Guide
, SA38-0538.
Most disk drives can move into the Model F80, but the hot-plug carriers used in
the Model F80 are new to RS/6000. Therefore, drive migration from the Model
F50 requires removal of the drive from the old blue-handled carrier and assembly
into the new Model F80 carrier. Migration of 68-pin drives will limit the
performance of the bus to which they are attached to SE 40 MB/s, rather than the
LVD 80 MB/s, which is possible for an entire complement of 80-pin Ultra2 drives.
Since the Model F80 has fewer disk bays, migration of data to larger disks may
be required during the upgrade. Refer to the
RS/6000 Systems Handbook 2000
,
SG24-5120 (available June 2000), or ask your IBM Business Partner or IBM
representative for further information.
The old chassis of Model F50 is to be returned to IBM.
When upgrading from an Model F50 that does not run AIX 4.3.3, it is required to
upgrade to AIX 4.3.3 or higher before you can upgrade the F50 system.
External Storage Expandability
The storage expansion for the Model F80 is can be provided through several IBM
storage options. The storage subsystems can be connected externally as
stand-alone tower or from within a rack.
External disk storage capacity can also be provided by attaching the Model F80
to storage servers. Using differential Ultra SCSI, the Model F80 can be attached
to the IBM Enterprise Storage Server. And by using the Fibre Channel Adapter,
the Model F80 can be attached to the IBM Fibre Channel RAID Storage server or
the IBM Enterprise Storage Server.
SP Attachment
The Model F80 can neither be attached as a logical node, nor is it supported to
be used as a Control Workstation (CWS) in an SP system.
