Hi, we're having a bad situation with a SAN iScsi solution in a production environment of a customer: the storage hardware may panic its kernel because of its software fault, with the risk of loosing data. We want to give the SAN manufacturer a last chance of correcting their solution: we're going to move data from the SAN to new fresh scsi-attached disks, for the time needed for them to find the bugs. Once they've certified us the solution, we will move back the data onto the SAN. Here comes the issue: we can't risk our customer's data to be again on a possibly faulty SAN, so we were thinking about reusing the scsi-attached disks as part of the zfs pool of the SAN partitions. The basic idea was to have a zfs mirror of each iscsi disk on scsi-attached disks, so that in case of another panic of the SAN, everything should still work on the scsi-attached disks. My questions are: - is this a good idea? - should I use zfs mirrors or normal solaris mirrors? - is mirroring the best performance, or should I use zfs raid-z? - is there any other possibility I don't see? Last but not least (I know the question is not pertinent, but maybe you can help): - The SAN includes 2 Sun-Solaris-10 machines, and 3 windows machines....is there any similar solution on the win machines?
Thanx for any help Gabriele Bulfon. This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
