Our Cyrus runs on Solaris with proper ZFS storage. This kind of storage
is fast, reliable and supports many nodes per directory without a
problem. Files check for backup is done in two hours for 50 million
files (Tivoli Storage Manager Backup).
We just can't virtualize this because in whatever "solution" the
underlying block devices get virtualized again. The only solution we
would have is to bind these storage devices (fc) exclusively on the
virtualized guest systems. Problem remains: Solaris 10 is not well
supported in VMware (no client tools and without them access remains
_SLOW_) nor in Xen/Sun xVM. In the latter OpenSolaris (and Solaris 11)
is the way to go (architecture i86xpv).
Just to give a reason why sometimes it _IS_ necessary or better to have
a real iron.
