Present 2 Vdisk as one logical volume on one host

Hi,

This may be simple question among you expert here. I have an EVA4400 and I wanna know if it's possible to present 2 vdisk as one logical volume on one host (a Windows 2003 host), or should I just use spanned volume on the host?

Thanks and regards.

Hi,

No I don't think you can combine two vdisks at the EVA level.

You'd have to use a spanned volume on the host.

Indra,

What is the reason you want to persent 2 vdisks in one logical volume instead of presenting one big Vdisk.

Re: Present 2 Vdisk as one logical volume on one host

Actually I want to create 4TB vdisk but from what I read, my EVA only allows me to create a maximum 2TB per vdisk, so I'm looking another way to present 4TB to the host.

And apparently I'm gonna use striped volume instead of spanned volume since each vdisk are already on vraid5. Any suggestions?

You can create a 4TB virtual disk on an EVA-4400 if:
- the controller firmware is quite new
- the disk group was created from this firmware AND
-- in enhanced mode

As far as I know, you cannot grow that virtual disk any further even with the most recent firmware, so it might not be a bad idea to use OS-level volume management. Then you can assign both 2TB virtual disks to both controllers and maybe enjoy better throughput.
