Configuration: VOB partitioning
Data distribution: VOBs
- How have you partitioned data among VOBs?
- VOB is a convenient administrative unit
- can be shuffled around for load balancing
- unit of replication for MultiSite
- Type of access determines load
- D.O. creation, mklabel -recurse, find queries expensive
- reading files, checkin/out much less
Data Distribution: disks
- Where do your VOB databases reside?
- … VOB storage pools ?
- Beware disk arm contention (between VOBs, between pools)
