I'm setting up a two-node cluster with 1U x86 servers. It needs a small amount of shared storage, with two or four disks. I understand that the J4200 with SAS disks is approved for this use, although I haven't seen this information in writing. Does anyone have experience with this sort of configuration? I have a few questions.
I understand that the J4200 with SATA disks will not do SCSI reservations. Will it with SAS disks? The X4140 seems to require two SAS HBAs, one for the internal disks and one for the external disks. Is this correct? Will the disks in the J4200 be accessible from both nodes, so that the cluster can fail over the storage? I know this works with a multi-initiator SCSI bus, but I don't know about SAS behavior. Is there a smaller, and cheaper, SAS array that can be used in this configuration? It would still need to have redundant power and redundant SAS paths. I plan to use ZFS everywhere, for the root filesystem and the shared storage. The only exception will be UFS for /globaldevices . -- -Gary Mills- -Unix Group- -Computer and Network Services- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
