I am a great fan of
Sun Fire X4500, you will see the benefit of having ZFS to virtualise all the disks and have the best protection without having to worry about lost of data like silent data corruption. BTW, I blogged about
X4500 a lot in the past.
Sun Microsystems is trying to make
Solaris as the platform for storage.
Those interested to implement
ZFS should read this
ZFS Best Practice Guide. As for most of my implementations, I prefer to do it this way,
use 2 disks (from different controller) to be mirrored with SVM (Solaris Volume Manager)
the rest of the 46 disks in one zpool
raidz (raid-5 equivalent) group of 6 disks across all the controllers
strip across 7 raidz groups
4 disks as spare
you will get 16TB usable space in a 24TB raw box
weekly zfs scrub in crontab to examine all data and verify checksum
Sun Fire X4500 has 6 controllers and the below is my disk layout.
If you configure probably, you don't even have to open up the box to replace any hard disk for the life time of the
Sun Fire X4500, hopefully.
