So far I have not come across this issue, I have read all the documentation and message threads on the internet about this array (not many I am afraid), and I have never seen such an issue mentioned, if not in the official documentation about a Fujitsu drive model which required a firmware upgrade. Perhaps you may want to be more specific. > As the modern host processors are several orders of > magnitude faster than a hardware RAID, it makes no I disagree, I still use some old UltraSparc II based boxes to host some basic services like file sharing, email, etc. However when I use ZFS is see the CPU going above 30% kernel with a plain zpool (no mirror, RAID, etc) on a T3B. ZFS is heavy on these processors. Coming back on our T3 firmware, I have a question about power saving: is there any way to configure the system to spin down the hard drives when the volume is idle? Now that we all have to watch for our power consumptions, I have saved 60 Watts already by replacing the 73GB original drives with FATA drives, but the T3 still drains 210 Watts. I bet that there are hundreds deployed in data centers around the world, just running idle.
