VMware today announced the release of VMware Site Recovery Manager (SRM) 8.2, and I am pleased to confirm that Hitachi Data Instance Director (HDID) fully supports this release with the release of updated Hitachi Storage Replication Adapter (SRA) v3.
SRM 8.2 introduces a number of important new features that will be beneficial for our mutual customers, focused on simplifying day-to-day DR management and security enhancements. You can find all the details here.
Hitachi Data Instance Director is highly integrated with the VMware ecosystem to deliver modern data protection and copy data management services, including orchestration between VMware Site Recovery Manager and Hitachi remote replication technologies to meet requirements for high availability, business continuity, and long-distance disaster recovery for critical applications and data.
VMware Site Recovery Manager automates the disaster recovery and testing process using either host or storage-based replication. Data Instance Director supports VMware's Site Recovery Manager (SRM) via the HDID Storage Replication Adaptor (SRA). The HDID SRA takes commands from SRM and returns state information for the relevant replication pairs or performs operations on the underlying block storage arrays to fail-over or fail-back VMware datastores.
The following diagram shows the recommended architecture for 2-site disaster recovery.
The Hitachi Data Instance Director software provides a higher level of automation for the configuration of local and remote replication relationships between primary and secondary systems.
For those critical applications and data sets that require high availability and near-zero downtime, storage-based replication is the appropriate data copy and movement technology. Using API calls, SRM calls the HDID SRA, which drives the HDID-managed replication pairs to perform replication setup, disaster recovery, and/or disaster recovery testing. The HDID SRA is an alternative adapter to the Hitachi SRA that many of our customers have been using in their SRM environments to date.
An HDID dataflow supporting SRM operations is shown below:
It is super easy to create replication, clone and snapshot workflows in the HDID user interface. No more custom scripting and maintaining replication configuration files – HDID does all that automatically.
In this example, Chesil is the storage array where production vSphere datastores reside. Jurassic is the storage array at the backup site. A continuous TrueCopy replication protects the production datastores, while batch Refreshed Thin Image snapshots at each site support the SRM recovery plan test feature.
Instead of TrueCopy, we could use Global-Active Device storage clustering to support an active-active high availability capability to facilitate a process to prove that one site could fail and services (VMs) could be run on the other site, without actually taking down one side to prove it.
This dataflow could also incorporate Hitachi Universal Replicator asynchronous replication to support long-distance disaster recovery, in a 2-datacenter topology or combined with synchronous replication in a 3-datacenter topology.
One cool thing is that this enterprise-class disaster recovery solution is available across the entire Hitachi Virtual Storage Platform (VSP) family, from small to mid-range to high-end storage arrays, as each model shares the same code base.
And if even this simplified DR approach seems too complicated for your organization, Hitachi Vantara offers a range of pay-as-you-go data protection as a service solutions.
