Figure 13-2 Allocating DB2 containers using a “spread your data” approach
In addition, consider the following:
You may intermix data, indexes, and temp spaces on the DS6000 Ranks. Your I/O activity
will be more evenly spread and thus will avoid the skew effect, which you would otherwise
see if the components were isolated.
For DPF systems, establish a policy that allows partitions and containers within partitions
to be spread evenly across DS6000 resources. You should choose a vertical mapping, in
which DB2 partitions are isolated to specific arrays, with containers spread ...
