2.5 375 MHz POWER3 SMP Thin Node (F/C 2056)
This section describes the 375 MHz POWER3 SMP Thin Nodes, also called the
Winterhawk-II Thin Node.
375 MHz POWER3 SMP Thin Nodes (F/C 2056) have PCI bus architecture and
either two or four 375 MHz 64-bit processors per node. These nodes are
functionally equivalent to an IBM RS/6000 7044-270 workstation. Your IBM
RS/6000 SP system must be operating at PSSP 3.1.1 (or later) to use these
nodes.
The node occupies half of a drawer (one slot). Up to 16 of these nodes can be
housed in a tall frame. When installed singly within a drawer, these nodes must
be placed in an odd-numbered node slot. For complete information on
node/frame configurations, see RS/6000 SP: Planning Volume 2, Control
Workstation and Software Environment, GA22-7281.
For electromagnetic compliance, these nodes are housed in an enclosure (F/C
9930). If you order a single node, a cover plate (F/C 9931) is included to fill the
even-numbered slot opening.
If you plan to install a 375 MHz POWER3 SMP Thin Node into an early style 2.01
m or 1.25 m frame, a power system upgrade is required. Once the power system
upgrade is done, these nodes are fully compatible with all existing SP system
hardware except High Performance switches.
2.5.1 Bus description
The 375 MHz POWER3 SMP Thin Node PCI bus contains two 32-bit slots, I2
and I3. The I1 slot is reserved for the optional SP Switch MX2 Adapter.
2.5.2 Requirements
375 MHz POWER3 SMP Thin Nodes occupy one half node drawer. They can be
asymmetrically configured for memory, hard disk drive, and adapters. Up to
sixteen of these nodes can be installed in a tall frame and up to eight in a short
frame. The mandatory requirements are:
򐂰
PSSP 3.1.1 (or later) on the control workstation, backup nodes, and
processor node.
Note: A 100BaseTX, 10BaseT, or 10Base2 adapter for the SP Ethernet is
integrated into the node and does not occupy a PCI slot.
