Hi Roman,
take a look on what NexentaStor is providing:
auto-cdp - a commercial plugin which simplifies significantly ZFS/AVS
management of primary/secondary hosts
auto-sync - a free service which supports sophisticated ZFS send/recv
over SSH, NC. Or use send snapshots over RSYNC - which could be ideal
for clouds. This service can be ideal solution for asynchronous ZFS
replication
auto-tier - a free service which supports RSYNC tiering. This service
works really well as a second tier archiving solution. Think of Netapp
over NFS periodic backups, etc
the development portal is http://www.nexentastor.org - the place where
NexentaStor open source developers and Partners getting together, so
this can provide you a free community support for open sourced plugins.

Hello list,
What are the options for building clustering storage using opensolaris? I'm
interested in HA solutions.
I tried only one option - AVS replication. Unfortunately, AVS configuration is too complicated. Groups, bitmaps, queues, rcp timeouts, slicing - it's just a nightmare to make it work and support in production when there are more that a couple of pools. And probably it's gonna be slow if there are jbods attached to a storage controller, or will require half of Ethernet ports to replicated more or less reliably. 10Gige interface for it - did anybody try?
Another option I'm looking into is sending snapshots. But regardless what we've
heard from sun - it's gonna slow down zfs operations. Creating a snapshot is
not quick on loaded pool, especially if storage controller manages many pools.
So, it's probably dozens of minutes delays in transferring snapshots over to a
standby server.
