Memory
5-19 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 for all
disk drives is as follows:
n 120 KB minimum
n 0.5 KB per MB of disk storage total for all disks
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.
MB Printer Mem
This field on the status page shows the size of the physical RAM
installed in the printer. When disk swapping is enabled (Administra-
tion/Memory/Enable Disk Swap), this field also gives the size of avail-
able virtual memory.
System Memory
Also known as System Use, this non-configurable client is the amount
of RAM used to run the printer’s operating system. It’s never
increased or decreased. The system memory subtracted from the
total amount of RAM identifies the amount of RAM available for all the
other memory clients.
Hard Disk Management
You can add up to three external SCSI hard disks to your QMS 4060
Print System. These hard disks serve as secondary storage places
for such items as downloaded fonts, emulations, and spooled data.
