>Environment:
Thanks Matt. My setup   Freebsd on thumb drive (no swap file)   only the 1GB memory that the seevrr ships with, 4 disks   250gb in DL320s. I was getting around 300   1000 IOPS in sequential workload with large files   works out to be between 50   80 MB/s.  (RAIDZ1   Stripped)Currently I am presenting each drive as a raid 0 volume to OS (Smart array ). da0/da1/da2/da3. I have tested replacement and rebuild, this works well. Only thing I have noticed is it takes the defined space of the volume, so replacing 250gb with 400gb only saw 250gb. I might have to install the HP CLI management package, delete the volume and create a new one. Since ZFS can dynamically grow on larger disks.Currently my interests are:- Performance. (what are the limitation of DL320s backend)- The DL320s has two internal thumb drive slots. Is it possible.- Issues related to lack of swap file. (I believe zfs caches within Kernel space, and this shouldn't be swapping)- Failure (Disk / Smart Array).Hope 
 you can spare some thoughts Thanks for your time again.
