Dear All,
First of all thanks for a fascinating list - its my first read of the
morning.
Secondly I would like to ask a question. We currently have an EMC Celerra
NAS which we use for CIFS, NFS and iSCSI. Its not our favourite piece of
hardware and it is nearing the limits of its capacity (Tb) . We have two
options:
1) Expand the solution. Spend £££s, double the number of heads, double
the capacity and carry on as before.
2) Look for something else.
I have been watching ZFS for some time and have implemented it in
several niche applications. I would like to be able to consider using ZFS as
the basis of a NAS solution based around SAN storage, T{2,5}000 servers and
Sun Cluster.
Here is my wish list:
Flexible provisioning (thin if possible)
Hardware resilience/Transparent Failover
Asynchronous Replication to remote site (1km) providing DR cover.
NFS/CIFS/iSCSI
Snaps/Cloning
No single point of failure
Integration with Active Directory/NFS
Ability to restripe data onto "widened" pools.
Ability to migrate data between storage pools.
As I understand it the combination of ZFS and SunCluster will give me all of
the above. Has anybody done this? How mature/stable is it. I understand that
SunCluster/HA-ZFS is supported but there seems to be little that I can find
on the web about it. Any information would be gratefully received.
Best Regards,
Vic
