Abstract
A method is used in managing data accesses in storage systems. An access path to a storage object is evaluated. The storage object is associated with a first storage processor of a storage system for providing access to the storage object. The storage object is accessed using a second storage processor of the storage system. The storage system includes source and destination storage pools configured such that performance characteristics associated with the source storage pool is different from performance characteristics associated with the destination storage pool. The storage object resides in the source storage pool associated with the first storage processor. Based on the evaluation, the access path of the storage object is changed to the second storage processor based on a policy. The policy determines available storage space in the destination storage pool associated with the second storage processor for migrating the storage object to the destination storage pool.
