2.8 IBM Netfinity 7000 Video Subsystem
The system board has an on-board integrated Cirrus Logic CL-GD5424 super
VGA controller connected to PCI to EISA bridge and comes standard with 1 MB
of on-board video memory. The video memory is not upgradable.
An older system board revision was shipped in the Netfinity 7000 with only 512
KB of video memory. There is an upgrade socket for video memory on this system
board. If you have such an older system you can optionally expand the on-board
video memory buffer size to 1 MB by adding one 40-pin 256 KB x 16, 70 nano
seconds (ns) fast-page Dynamic Random Access Memory (DRAM). Figure Table
9 shows you a list of possible DRAM modules.

Note: These part numbers are not IBM part numbers
The Netfinity EXP10, will only support a total of 8 x 9.1 GB 10K
rpm HDDs (specifically, part number 01K7968). IBM will support
mixed configurations of these drives.
A flyer will be included with this drive option that specifically
recommends to the customer that the middle two slots be
populated with the dummy trays. The middle two slots run hottest
and so should be left with the dummy trays only. Whatever the
mixed configuration is, when even a single 9.1 GB 10K rpm drive
(01K7968) is included in this configuration the maximum number of
drives supported in the Netfinity EXP10 is eight.
This is a power consumption issue. If a customer installs nine or
ten of these HDDs, the customer will lose redundancy. Both power
supplies in this case will be operating at 60% capacity. With both
operational, the customer will not experience any problems.
However, should one power supply fail, the remaining power supply
will not be able to maintain the necessary power, a breaker will trip
and the system will shut down.
