zfs discuss - Jun 2008 - creating ZFS mirror over iSCSI between to DELL MD3000i arrays

Hi,

I''ve looked at  ZFS for a while now and i''m wondering if
it''s possible on a server create a ZFS mirror between two different
iSCSI targets (two MD3000i located in two different server rooms).

Or is it any  setup that you guys recommend for maximal data protection.
 
Thanks,

/Thom

ZFS can mirror disk devices.. If your iSCSI targets show up as disk
devices, they can be mirrored. Try it for yourself ;)

If you have very different latency to them, performance will suffer
(like you only used the slower one)..

Hi Tomas,

I will try it my self, but it''s just that if i google the subject i
only find old entries describing things as kernel panics and system freeze.
I''m just wondering if this problem is fixed in the newer releases, or
if there is another recommended way to keep data stored on different sites in
realtime. We''re talking about +8TB of data.

Thanks,

/T
