The disk subsystems could be attached to up to 15 computers giving a theoretical upper limit of 240 workstations in a single cluster.
This concurrent processing requires the 9333 disk subsystem.
Fibrechannel permits connecting the same disk subsystem to several computers.
It was a dual drive 5 " floppy disk subsystem for Commodore International computers.
This feature may need to be enabled even if it is available on the disk subsystem.
The 9333 disk subsystem is now available on the 340 and 350E.
The 605 also powered peripheral controllers, including the 658 disk subsystem and the 721 communications processor.
This method was also used for CPU, RAM and disk subsystem but there are other subsystems that need to be considered in total power consumption.
Other companies found a niche market for replacements for legacy PDP-11 processors, disk subsystems, etc.
The PCF has tightly-coupled clusters with very fast disk subsystems, currently operating at a peak capacity of 855 teraflops.
