21 Dell Storage PS Series Architecture: Load Balancers | TR1070
Fourth, if a customer has chosen to override the automatic placement of volumes by the capacity balancer by
using the CLI bind command, all balancing of any sort is disabled for that volume. Note that this does not
disable the APLB for other application workloads that may be using the same member that the volume is
bound to.
A case where the APLB behavior should be observed more carefully is when volume RAID preference is
utilized. If the pool contains only one member of the selected RAID type, the effect of the RAID preference
option is equivalent to the CLI bind command, and the APLB will not be able to optimize the workload. On the
other hand, if there are multiple members in the pool providing the selected RAID level, then the CLB will be
able to create multiple volume slices. In this case, then the APLB will work as expected.
