This is interesting. I have a two-node SPARC cluster that uses a multi-initiator SCSI array for shared storage. As an application server, it need only two disks in the array. They are a ZFS mirror. This all works quite nicely under Sun Cluster. I'd like to duplicate this configuration with two small x86 servers and a small SAS array, also with only two disks. It should be easy to find a pair of 1U servers, but what's the smallest SAS array that's available? Does it need an array controller? What's needed on the servers to connect to it? -- -Gary Mills- -Unix Group- -Computer and Network Services- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
