[mdlug] New Server - Hardware Configuration

[Michael ORourke]

What about a small SAN device?  Also, you could attach an iSCSI SAN to a 
front-end Linux server.  Another thing you didn't mention was backups. 
Having multiple RAID sets is NOT a backup strategy.  This is a common 
mistake many people make.
If it were me, I would try to seperate the storage from the server.  Perhaps 
with a RAID6 configuration and a hot spare.  That way you could lose up to 3 
drives and still be fully operational.  There are several low cost SAN 
vendors out there which are certainly worth a look.  I don't quite 
understand why they are pushing a server with 3 RAID cards.  Sounds like 
this might become an expensive and difficult to support file server.
