The ProLiant 7000
memory expansion board has the following features:
•
Error Checking and Correcting (ECC) Memory with single-bit error correction and detection
down to a single DIMM, and multi-bit error detection down to the memory bank.
•
Extended Data Out (EDO)

, 60-ns DIMMs in 16-, 32-, 64-, 128-, and 256-MB sizes.
•
Expandable to 8 GB (2 memory expansion boards x 16 DIMMS x 256-MB/DIMM).
•
Peak data transfer rate of 1.6 GB/s
•
Concurrent CPU-to-memory and PCI-to-memory accesses.
Figure 3: Bank designations and DIMM socket numbers on Memory Expansion Board.
The peak memory transfer rate of 1.6 GB/s supports the maximum data rates on the processor bus
(800 MB/s) and PCI buses (532 MB/s) concurrently, using industry standard ECC EDO DIMMs.
Each memory board contains four banks of 4:1 interleaved DIMMs.
Accesses to banks of
memory on the memory board are overlapped using Address Bit Permuting (ABP).
Accesses to
banks of memory that reside on separate boards are overlapped using Card to Card (C2C)
interleaving.
The ABP and C2C interleaving features are automatically enabled when banks of
memory are populated with the same type of DIMMs.
I/O Board
The I/O board (Figure 4) has ten expansion slots and three 33-MHz PCI buses:
•
Five 64-bit PCI Hot Plug slots (PCI Bus 3)
•
Four 32-bit PCI Hot Plug slots (PCI Buses 1 and 2)
•
One ISA modem slot
The five 64-bit PCI expansion slots on PCI Bus 3 include three PCI Hot Plug slots and two PCI
Hot Plug slots with extended SCSI.
All 32-bit PCI adapters work in any of the five 64-bit
expansion slots, and all 64-bit adapters work in the 32-bit expansion slots.
In addition, the two
extended PCI slots allow the Smart Array 3100ES Controller to route three SCSI buses to the I/O
