I am trying for a best performance scenario combined with data protection because the pool may hold data for up to a week. I had considered a stgpool that spans all the disks with mirrored partitions versus using hardware ssaraid. or using individual filesystems with predefined volumes using mirrored partitions. my current SSA adapters do not have fast-write cache but I will have access to those adapters soon.

Tim, "It is possible to pre-define the volumes with DEFINE VOLUME (I have not tried this)." The limitation of one file system per FILE device class affects scratch volumes only. As far back as ADSM 3.1 I had FILE volumes belonging to one DevClass defined on six different disk file systems. Your suggestion works just as one would expect. We pre-defined the FILE volumes to the storage pool and everything worked fine for years. Allowed us to spread the disk load across all those disks without using RAID.
