Learn SRM – Part 3 – Understand Minimum Requirement for SRM Setup in Home Lab

Continuing to SRM 8.1, now we are going to deploy this in our environment.  To be very honest, we are using our home lab to explore Site Recovery Manager. Hence there are certain specific requirement in your home lab.

  • Here we are using HP StoreVirtual VSA for array based replication as we do not have physical storage available. Let me tell you one point here that HP StoreVirtual VSA has not released any compatible SRA for SRM 8.1 as on date. So you can use EMC UnityVSA instead of HP StoreVirtual VSA. Here I had already downloaded everything and configured my lab using HP VSA, and faced compatibility issue while configuring SRA. So later I reconfigured my storage part using EMC UnityVSA which has compatible SRA for SRM 8.1. You can refer to compatibility matrix here https://www.vmware.com/resources/compatibility/search.php?deviceCategory=sra
  • SRM will use embedded database in our home lab. But if you are going to deploy in production environment, you can check supported platform and database compatibility matrix for SRM at https://docs.vmware.com/en/Site-Recovery-Manager/8.1/rn/srm-compat-matrix-8-1.html
  • vCenter will use embedded database in our home lab environment.

Architecture of our Home Lab is as shown below: –

I will go through the specific requirement for Site Recovery Manager as per VMware guidelines. You have to ensure that you are meeting these requirements if you are going to deploy SRM in your production environment.

  • You must run the same version of Site Recovery Manager on both sites.
  • The version of vCenter Server must be compatible with the version of Site Recovery Manager. For information about compatibility between vCenter Server and Site Recovery Manager versions, see vCenter Server Requirements in the Compatibility Matrices for Site Recovery Manager 8.1 at https://docs.vmware.com/en/Site-Recovery-Manager/8.1/rn/srm-compat-matrix-8-1.html.
  • Each site must have at least one datacenter.
  • If you are using array-based replication, the same replication technology must be available at both sites, and the arrays must be paired.
  • If you are using vSphere Replication, you require a vSphere Replication appliance on both sites. The vSphere Replication appliances must be connected to each other.
  • The vSphere Replication appliances must be of the same version.
  • The vSphere Replication version must be compatible with the version of Site Recovery Manager. For information about compatibility between vSphere Replication and Site Recovery Manager versions, see vSphere Replication Requirements in the Compatibility Matrices for Site Recovery Manager 8.1 at https://docs.vmware.com/en/Site-Recovery-Manager/8.1/rn/srm-compat-matrix-8-1.html.
  • The recovery site must have hardware, network, and storage resources that can support the same virtual machines and workloads as the protected site. You can oversubscribe the recovery site by running additional virtual machines there that are not protected. In this case, during a recovery you must suspend noncritical virtual machines on the recovery site.
  • The sites must be connected by a reliable IP network. If you are using array-based replication, ensure that your network connectivity meets the arrays’ network requirements.
  • The recovery site should have access to comparable public and private networks as the protected site, although not necessarily the same range of network addresses.
