We're using ZFS compression on Netbackup Disk Cache Media Servers. I have 3 media servers with 42TB usable each, with compression enabled. I had to wait for Sol10 U4 to run compression because these are T2000's and there was a problem that zfs was using only 1 compression thread per pool which made it too slow. But after U4, I have no problem handling bursts of nearly 2Gbit/s of backup streams in over the network while still spooling to a pair of 30MByte/s tape drives on each server. -Andy _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
