What kind of storage backend do you guys use if you see disk IO bottlenecks
when storing ceilometer events and metrics? In my current configuration I
am using 300 GB 10K SAS (in hardware raid 1) and iostat report does not
look good (upto 100% unilization) with ceilometer consuming high CPU and
Memory.  Does it help adding more spindles and move to raid 10?
