The cornerstone of SRM is the ability to failover a virtual infrastructure from one datacenter to another. Understanding how this process works with the VMAX/PowerMax storage array and Symmetrix Remote Data Facility (SRDF) is an integral part of datacenter migration and disaster recovery.
The SRDF SRA supports two modes of SRDF replication: 2-site and 3-site (Star and Non-Star) replication. This chapter will deal with recovery using 2-site replication while the next chapter will discuss recovery with 3-site SRDF replication.
Specifically, this chapter will discuss the following topics as they pertain to 2-site SRDF configurations:
