With ZFS on a Solaris server using storage on a SAN device, is it reasonable to configure the storage device to present one LUN for each RAID group? I'm assuming that the SAN and storage device are sufficiently reliable that no additional redundancy is necessary on the Solaris ZFS server. I'm also assuming that all disk management is done on the storage device.
I realize that it is possible to configure more than one LUN per RAID group on the storage device, but doesn't ZFS assume that each LUN represents an independant disk, and schedule I/O accordingly? In that case, wouldn't ZFS I/O scheduling interfere with I/O scheduling already done by the storage device? Is there any reason not to use one LUN per RAID group? -- -Gary Mills- -Unix Group- -Computer and Network Services- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
