Hello listmates,
I would like to build a 12-15 TB RAID 5 data server to run under
ContOS. Any recommendations as far as hardware, configuration, etc?
Thanks.
Boris.

Ryan's hardware recommendations are good. But I wouldn't run a RAID5
volume that large, software or hardware. It's just too risky as
rebuilds will take days and the chances of hitting a non recoverable
read error would be near 100% on a volume

Smaller volumes is best, but really it depends on your I/O type as well.

Just finished building a new server for inhouse use. 12.8TB
Needed a nfs and samba server which could store 10TB and be reliable.
Also wanted to replace out DHCP server and our internal DNS server.
So needed to run dnsmasq plus ntp for time serving.
This machine replace 3 older units.
We used
