Create one Volume over multiple P2000 Enclosures ?
We have three MSA P2000G3 connected via iscsi to a Proliant DL380 running CentOS, each MSA has ~20TB Diskspace configured.
Our Customer now wants all this Storage combined to on big (~60TB) Volume.
Is this even Possible ?

Re: Create one Volume over multiple P2000 Enclosures ?
You could create a software-raid or LVM on the CentOS pretty easily though to combine several LUNs/disks.

Re: Create one Volume over multiple P2000 Enclosures ?
Hi Johan, thanks for the answer.
By "some disk-shelves" you mean additional Hardware besides the Proliant and the P2000 Enclosures ?
I've also thought about a Software RAID but for me this would be another Layer ontop of this somewhat "unreliable" configuration.
The user wants space and speed, though a RAID 0 over all enclosures might sound good, but imo this would be a very risky setup, but i haven't convinced him yet ... ;)

With "some disk-shelvse" I meant connecting for example MSA70 behind a P2000 controller.

What we have is three times this :
HP P2000 G3 iSCSI MSA Dual Controller LFF Array System (BK830A)
Each Array System/MSA/Enclosure (whats the correct name?) has two iscsi controllers, 12 hdds and is connected over a dedicated switch to the Proliant.

Re: Create one Volume over multiple P2000 Enclosures ?
Volume managers like LVM are able to do this, but what should be the reason why?
If 1 P2000 fails, 60TB data are gone!
Hope this helps!
Regards
Torsten.
