Requirements; Options - IBM RS/6000 SP Handbook

Single POWER3 SMP thin nodes and single 332 MHz SMP thin nodes may
be mixed in a thin node drawer.
If a frame has more than six single SMP thin nodes installed, that frame will
have an uneven weight distribution. You must be careful when moving these
frames.

2.10.3 Requirements

332 MHz SMP thin nodes occupy one half of a node drawer. When two SMP thin
nodes are placed in one drawer, the nodes may be asymmetrically configured for
memory, disk, processor speed, and adapters. Up to sixteen 332 MHz SMP thin
nodes may be installed in one tall frame and up to eight in a short frame.
The mandatory requirements are:
PSSP 2.4 (or later) on the control workstation, backup nodes, and processor
node
Two processors (mounted in one slot)
256 MB of memory
4.5 GB of hard disk drive (with internal booting)
An upgraded power system on older frames

2.10.4 Options

Each 332 MHz SMP Thin node is functionally equivalent to an RS/6000
7025-F50 and has the following options:
Two processor slots allowing a maximum of four processors per node.
Two memory slots supporting up to 3 GB of memory.
Two disk bays supporting up to 36.4 GB of storage (18.2 GB mirrored).
A dedicated Mezzanine bus (MX) slot for an optional switch adapter.
Two 32-bit PCI slots for communication adapters.
Integrated 10BaseT/10Base2 Ethernet (only one port may be used at one
time).
Integrated SCSI-2 Fast/Wide.
Standard Service Processor.
External nine-pin RS-232 on the planar S2 port (supported only for HACMP
serial heartbeat); a 9 to 25-pin converter cable is included with the node
– Node-to-node HACMP cable (F/C 3124)
