Allocating MySQL cluster nodes for MogileFS database

[Jared Klett]

	mmmm I see. so I should try to get 8 GB into the file servers as
well.

	good call on RAID-10. that's what we currently use for our
non-cluster MySQL master servers (slaves are RAID-1) and it works well.

	thanks!

cheers,

- Jared

I suspect your file servers are fine, though given that MogileFS copies
its files into memory (e.g. the get_file_data call) the more memory the
better.

The only other comment I would make is to configure your MySQL boxes
with Raid 10.
You want high IO rates, particularly if your DB size will be large, and
of course you want the reliability.
