[Disksim-users] More about the source code

[Greg Ganger]

disksim_cacheXXX.[ch] for any XXX (including none) relates to the memory
cache at an "intelligent controller" (not the on-board disk cache).

disksim_diskXXX.[ch] for any XXX (including none) relates to the disk
model.  So, disksim_diskcache.[ch] is the code for the on-board disk
cache.

Good luck.

Greg

But in the PhD thesis "System-oriented evaluation of I/O subsystem performance" included one sentence "The disk drive module includes a separate cache/buffer submodule because of the specialized nature of common on-board disk cache management policies."(at the bottom line of the page 105). Does that to say there is a separate on-board cache implemente in the source code?
