Hello! I have a HP 3080X SAS/SATA 8 port mpt(4) controller card that I want to = use in a ZFS setup. My problem is that the write cache is not enabled on disks that are not = a part of a RAID volume (RAID0 or RAID1). The write speed is limited to about 20MB/s with both UFS and ZFS. If I create a RAID0 volume with mptutil(8) and then destroy it, write = cache gets enabled and the write speed reaches about 60MB/s with UFS and = ZFS.=20 Unfortunately it won't survive a reboot. Has anyone else seen this problem with mpt(4) controllers and/or knows = how to fix it? Regards Stefan dmesg: Copyright (c) 1992-2012 The FreeBSD Project.
