VMware Live Site Recovery Manager (VLSR), formerly known as VMware vCenter Site Recovery Manager (SRM), leverages storage array-based replication such as PowerFlex replication to protect virtual machines in VMware vSphere environments. The interaction between VLSR and storage array replication is governed through a well-defined set of specifications. These VMware-defined specifications are implemented by the storage array vendor as a lightweight application known as the storage replication adapter (SRA).
The PowerFlex SRA enables VLSR to interact with the PowerFlex storage environment. It allows VLSR to automate storage-based disaster restart operations on PowerFlex. The PowerFlex SRA supports a single mode of replication, asynchronous, on both PowerFlex 3.x and 4.x. This document provides implementation procedures and best practices for automated disaster recovery of VMware environments using PowerFlex, asynchronous replication, the PowerFlex SRA, and VLSR.
