RPO, RTO, WRT, MTD…WTH?!

Some time ago, I was engaged in a discussion with one of our customers to investigate the possibility of VMware Site Recovery Manager implementation in their datacenter. The discussion turned technical pretty soon and when I asked what their RPO or RTO requirements were, they could not answer it straight away simply because they didn’t know what it was or what it meant. And when I mentioned WRT and MTD, they were stunned even more. […]

Upgrading VMware vCenter Site Recovery Manager from 5.0 to 5.1

A little while ago VMware released vCenter Site Recovery Manager 5.1 together with other products and vCloud Suite. Here is a quick summary of “What’s new in SRM 5.1” and the new improvements. SRM 5.1 supports reprotect and failback with vSphere Replication. Previously, you could only perform reprotect and failback on array-based protection groups. In SRM 5.1 you can perform reprotect and failback on vSphere Replication protection groups. The SRM Server in SRM 5.1 is […]

Port requirements for Site Recovery Manager 5 and vCenter Server 5

A few days ago Troy Hampel (@MrTroyH) asked me on Twitter if I had some troubleshooting blogs about resource mapping permission in Site Recovery Manager 5, unfortunately I didn’t, simply because I did not came across any issues with permissions when I was implementing my SRM 5 infrastructure 🙂 But this gave me an idea to summarize the ports used by the Site Recovery Manager 5 between the Protected Site and the Recovery Site but […]

How To: Upgrade VMware vCenter Site Recovery Manager 5.0 to version 5.0.1

Here is a quick “how to” on upgrading the VMware vCenter Site Recovery Manager from version 5.0 to version 5.0.1. It is recommended that you perform an in-place upgrade rather than a new installation as this will preserve all reports, recovery plans, protection groups etc. The upgrade procedure must also be performed on the Recovery Site. Before you begin make sure the following criteria are met: SRM database is backed up The SRM software is […]

How To: VMware Site Recovery Manager 5 – Part 10 (Final): Migration and Failover

So far we covered almost any aspect of the VMware vCenter Site Recovery Manager. We have prepared and set up the infrastructure, paired the sites, configured the VR replication, set up inventory mappings, created a protection group, configured a recovery plan and performed a test failover. In this part we will perform a planned migration and an unplanned failover from the Protected Site to the Recovery Site to simulate a disaster recovery scenario. But first, […]

How To: VMware Site Recovery Manager 5 – Part 9: Recovery Plans

The protection group is now configured and the VMs are replicating to the Protected Site. The next step in the SRM deployment is to configure a recovery plan. “A recovery plan is an automated plan for a full or partial disaster recovery failover.” In other words, a recovery plan is like a runbook which is based on a protection group. The SRM recovery plan consists of the following: List of protected VMs included in the […]

How To: VMware Site Recovery Manager 5 – Part 8: Protection Groups

After configuring the replication of the virtual machines in SRM we can now create Protection Group(s). So what exactly is a protection group? Well, it’s quite self-explanatory 🙂 “A protection group is a group of virtual machines that fail over together to the recovery site during a test or a recovery procedure.” The protection group can be used in one or multiple recovery plans which we will create later. Protection groups can be Array-based or […]

How To: VMware Site Recovery Manager 5 – Part 7: VM Replication

Before we can protect a single virtual machine or a group of virtual machines, the virtual machine files need to be replicated from the Protected Site to the Recovery Site. Since we have already set up a VR infrastructure we will proceed using this mechanism. In this case, we will skip the replication configuration of a single VM and concentrate on configuring replication of multiple VMs since it’s the most common setup in a virtual […]
