Do we all know that VMware vsphere replication now comes FREELY bundled with all eligible vsphere licenses. Let us give you a small background about what vsphere replication do.
- truly hypervisor level replication engine by VMware.
- Copies a virtual machine to another location, within or between clusters, and makes that copy available for restoration through the VMware vCenter Server Web-based user interface.
- Enables replication on a per–virtual machine basis.
- vSphere Replication can be configured to ensure consistent application data, along with virtual machine data, with one simple click when configuring a virtual machine for replication.
- There are no application agents required so any time of application and any guest OS (96+) can be protected without knowing complexities of application configuration for DR/backup.
- RPOs (Recovery Point Object) for each virtual machine can be defined, ranging from 15 minutes to 24 hours which will be applicable to most of your customers.
Does it mean I will not need VMware SRM??? The answer is NO, SRM doesn’t compete with vsphere replication, it complements VR or a mandatory component to reduce RTO(Recovery Time Object). You will need VMware Site Recovery Manager (SRM) for
- Providing complex orchestration for disaster recovery to reduce RTO to 30 mins or more.
- Frequent non-disruptive drill test can be executed in scheduled and planned manner with just few clicks
- It takes 5 CLICKS to move applications protected (Site A) to Recovery (Site B) Site.
- Automated failback is possible from Site B to Site A with just 5 CLICKS. (The above two pointers will make ears open for your customers)
- Databases should boot first and then dependent apps, which means SRM can help you decide on booting order just the way you want it.
- You can configure VM’s for networking at both sites the way you want them to be accessed.
