There are few things to keep in mind while configuring ZFS. 1. As far as possible, give entire disk to ZFS, not slices. If you have to use slices, at least give slices from different disks. Using slices from same disk is bad idea as it results in extra rotations for the disk. 2. If you are using h/w raid luns, make sure that you use luns from different controllers in a zpool so that your controller would not become bottleneck. For example, zpool create mypool mirror c0t0d0 c1t0d0 <for mirrored pool> zpool create mypool mirror raidz c0t0d0 c1t0d0 <for single parity raidz pool>

Hi, I am pretty new to Solaris 10 and am slowly getting used to some of its niceties - zfs being one of them. On my first venture with it, I have configured a storage pool containing a few slices from a single disk. This disk is under a hardware raid control, the server in question being a Sunfire X4200. I have infact mirrored the disk at the bios level. I intend to use Zfs more for volume management rather than redundancy. I have also read some of the recommendations for ZFS mainly of having seperate whole disks to create the pool. If this is for performance reasons, how good/safe is my configuration of using multiple slices to create my pool? I also have plans of using LUNS from my Clariion Storage which may be hardware mirrored or RAID5 LUNs. At the host can I treat them as seperate disks and configure a pool of multi-terrabyte dimensions and have filesystems > 2TB? Thanks in advance for your replies. --SF _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
