Memory
5-21 Additional Technical Information
The amount of memory needed for the disk cache client is dependent
on the size of the disk, the number of disks, the number of subdirecto-
ries on each disk, and the amount of memory dedicated to caching.
As long as the disk cache is enabled and there is enough memory in
the disk cache, all disks are accessible. If insufficient memory is allo-
cated to the disk cache, some disks may be seen while others are
not.
The recommended amount of memory for the disk cache client is as
follows:
n
20 KB internal usage
n
0.5 KB per MB of disk storage total for all disks
n 100 KB of memory dedicated to caching
For example, the recommended amount of memory for the disk
cache for a single 120 MB hard disk would be 180 KB, and for two
120 MB hard disks it would be 240 KB.
» Note: After you format a hard disk and the FORMAT COMPLETE
message is displayed in the message window, the formatted disk may
not be available to the system until the printer is turned off and then
on again.
You can increase the disk cache size in the following ways:
n
Add more memory, which automatically increases the disk cache
client’s size. See chapter 6, “Printer Options,” for information on
installing additional printer memory (SIMMs).
n Set Administration/Memory/Enable Disk Swap to Yes. Any extra
memory is distributed to all memory clients.
n
Take any memory, if available and not being used by other cli-
ents, and add it to the Administration/Memory/K Mem Display
memory setting.
▲ Caution: This option should be used only by individuals who are
familiar with adjusting memory client’s values. Incorrect use of
this option could cause the system to operate incorrectly.
