What is Symmetrix Optimizer?

Symmetrix Optimizer improves array performance by continuously monitoring access patterns and migrating devices (Symmetrix logical volumes) to achieve balance across the disks in the array. This process is carried out automatically based on user-defined parameters and is completely transparent to end users, hosts, and applications in the environment. Migration is performed with constant data availability and consistent protection.

Symmetrix Optimizer can be utilized via either the EMC Symmetrix Management Console GUI or CLI, where users can define the following:

  • Symmetrix devices to be optimized

  • Priority of those devices

  • Window of time that profiles the business workload

  • Window of time in which Optimizer is allowed to swap

  • Additional business rules

  • The pace of the Symmetrix Optimizer volume copy mechanism

After being initialized with the user-defined parameters, Symmetrix Optimizer operates totally autonomously on the Symmetrix service processor to perform the following steps:
