4.5. Maximum Configuration
•
Two CPUs.
•
8 GB of memory.
•
587.2 GB of disk space.
•
Five PCI slots.
4.6. Operational Requirements
•
AIX 4.3.3 or later.
4.7. Bus Frequency and Bandwidth
One 128-bit wide system bus operating at, 93.75 MHz with the 375 MHz CPU board (1:4 ratio), and at
90 MHz with the 450 MHz CPU board (1:5 ratio).
The theoretical maximum bandwidths for a 2-way 450 MHz configuration are:
•
Memory bandwidth: 1.44 MB/s
•
Processor bandwidth: 1.44 MB/s
•
Bandwidth of the 64-bit PowerPC 6xx bus, operating at 66 MHz, used to the I/O interface: 528
MB/s
Two peer PCI buses (32-bit at 33 MHz and 64-bit at 50 MHz):
•
Two 64-bit@50MHz/3.3V slots
•
One 64-bit@33MHz/5V slots
•
Two 32-bit@33MHz/3.3V slots.
4.8. Power Kits for the PL220T
4.8.1. CPU Board with 1-way POWER3-II@375MHz - 4MB L2 cache (CPUG073)
The Power Kit contains the following items:
•
One 1-way POWER3-II@375MHz CPU board - 4MB L2 cache.
Operational Requirements
•
Any PL220T with one free CPU slot.
•
1-way POWER3-II@375MHz CPU boards cannot be used with 1-way POWER3-II@450MHz
CPU boards.
