6 Dell EMC SC Series: Disaster Recovery for Microsoft SQL Server Using VMware Site Recovery Manager | CML1018
1 VMware Site Recovery Manager overview
Site Recovery Manager (SRM) is a disaster recovery testing, execution, and planned migration product for
VMware virtualized data centers. It leverages the power of storage replication and virtual machine mobility to
provide automated disaster recovery testing and execution as well as planned migrations of virtual machines
between active sites. The bundled automation combined with storage replication yields unmatched
capabilities to meet RTO and RPO requirements when compared to legacy disaster recovery plans and
physical servers.
1.1 Architecture
For most deployments, the Site Recovery Manager infrastructure and resulting architecture is mirrored
between two sites. Each site contains storage which replicates between sites, vSphere hosts which provide
compute resources for running virtual machines, and lastly the software which is used to manage VMware
vSphere
®
, SRM, and the storage. Each site also contains other infrastructure components such as physical
servers, networking, firewalls, authentication, and directory services. Site Recovery Manager 5.0 and newer
can accommodate two site designs: the traditional active/DR site design as well as an active/active site
design.
