Abstract: Techniques are provided for implementing storage block balancing using volume part migration. One method comprises obtaining a capacity utilization of storage blocks each storing a portion of one or more storage volumes; and when the capacity utilization of a given storage block is above an upper target threshold, migrating a volume part of the given storage block to a different storage block having a capacity utilization below a lower target threshold, wherein the different storage block is within a same storage pool as the given storage block, and wherein the volume part comprises a subset of a storage volume.

Abstract: Techniques are provided for generating host connectivity plans with load balancing and resiliency. One method comprises obtaining a number of storage system target ports needed for a given host; identifying available target ports in the storage system and an input-output (IO) target component associated with each available target port; and calculating the host connectivity plan until the host connectivity plan includes the obtained number of target ports by: (i) selecting at least one IO target component not already in the host connectivity plan that satisfies a resiliency policy and/or a load balancing policy; (ii) selecting at least one target port associated with the selected at least one IO target component and (iii) adding the selected at least one target port to the host connectivity plan. The resiliency policy may require connectivity without a single point of failure. The load balancing policy may specify that the IO target components serve a substantially equal IO load.
