Hi,

In general I agree on a maximum possible usage of ~80%, but if I read
the mails correctly she has something about 2GB of RAM but 5 x 73 GB
Harddisk for the cache_dirs only. This is about 300GB of storage, what
about the RAM requirements when using ~80% ?

IMHO there is not enough RAM for all disks in the machine. As having
more disks gives more speed I think reducing the maximum usage is a
better option than reducing the number of disks.

Good idea for such a large storage. Any idea how this will influence the
RAM requirements?
