what are the chances of this, our Exchange server, mail store which is on RAID 0, both HDD's failed !!!!

Also think the controller may be bust :p

oh well happy days, will keep me busy.
 
Why anyone would use disk striping on an Exchange box is beyond me, pretty much begging for it.

Now then... let's see if those backups work :D

Good luck!
 
Exchange on a RAID 0 array - do you fancy naming and shaming....actually you'd better not, but that is funny.

Our latest Exchange box is RAID 1 for our OS and then RAID 5 for all of the stores and logs.
Sure the RAID controllers could fail...

Next you'll tell us that not only is it RAID 0, it's IDE/SATA RAID 0 :)
 
Now might be time to impress and strongly suggest they move away from RAID0. Even if a single drive failing in that configuration all the data will be lost!

RAID10 or 11 is the way to go ;)

Ummm...the guy in charge at your place...does he actually know what he is doing?
Because choosing RAID 0 for an Exchange server because "it's quicker" - although true (with respect to it being faster than RAID 1) is certainly not the first thing you should factor in.
With e-mail it has always got to be redundency followed by capacity then worry about getting the best disk performance.

He needs to be shot. I've only gone for RAID 5 with exchange, I know it can still only toloerate 1 disk failing. I have had it where 2 disks in a RAID 5 set-up failed. But the client did fail to tell me that that the AC failed over the weekend so it was the heat that killed them.
 
cheers guys. well think it is acutually the raid controller that's gone.

300 users ( at a guess ) with no emails ) joy. Pretty stumped for what to do now realyl as got no other similar hardware to restore a backup to and the server is out of warrenty.
 
<cough>
RAID 0 and no restore server (for a 300 user company!)
class :p

I guess if something is possible, then someone out there will do it.
I'd look for another job rather than work with this chap, god knows what else he's cocked up :eek:


you could probably frig a desktop as an Exchange server,
and offload the mailboxes into PST's and onto another server.
It could get you up and running for a few days

or

There is 3rd party software to extract the mailbox data from the backup files, just for situations like this (ie no restore server)

If it is the RAID controller that has gone then your boss might just be able to keep his job.
Find somewhere that has exactly the same make/model of controller and simply replace.
All the data will hopefully be intact accross his HD's so there will be no recovery time required.

...you're going to tell me now that the RAID controller is built into the motherboard aren't you? :)

Indeed it is :D

plus it is a Dell so might cost a few quid.

oh the joys.

plus with 300+ users wouldn't like to be the one to manually export the user's PST files !!

someone correct me here,
...swapping in a new Dell raid card may not fix the array :eek:

(hope I'm wrong, swappable RAID hardware is one of the plus sides of having a HP I've been told)
