What allocation strategy?
Data in each volume is stored in a single storage pool. Because there is only one user
data storage pool, allocation strategy is not an issue, so we’ll accept the default
allocation strategy: Round Robin.
What block size and stripe breadth should we use?
Because video streams involve mostly sequential reads and writes, the video storage
pools can benefit from a larger file system block size of 64 KB together with a 16-block
stripe breadth. This should provide good space utilization.
