After you install Site Recovery Manager, it remains in evaluation mode until you install a Site Recovery Manager license key.
After the evaluation license expires, existing protection groups remain protected and you can recover them, but you cannot create new protection groups or add virtual machines to an existing protection group until you obtain and assign a valid Site Recovery Manager license key. Obtain and assign Site Recovery Manager license keys as soon as possible after installing Site Recovery Manager.
Site Recovery Manager licenses allow you to protect a set number of virtual machines. To obtain Site Recovery Manager license keys, go to the Site Recovery Manager Product Licensing Center at http://www.vmware.com/products/site-recovery-manager/buy.html, or contact your VMware sales representative.
Site Recovery Manager License Keys and vCenter Server Instances in Linked Mode
If your vCenter Server instances are connected with vCenter Server instances in linked mode, you install the same Site Recovery Manager license on both vCenter Server instances.
Site Recovery Manager License Keys and Shared Platform Services Controller Instances
You can share an external Platform Services Controller across several vCenter Server instances. In this case, you can use the same Site Recovery Manager license on different vCenter Server instances as long as the vCenter Server instances belong to the same Platform Services Controller.
Site Recovery Manager License Keys and Protected and Recovery Sites
Site Recovery Manager requires a license key on any site on which you protect virtual machines.
Install a Site Recovery Manager license key at the protected site to enable protection in one direction from the protected site to the recovery site.
Install the same Site Recovery Manager license keys at both sites to enable bidirectional protection, including reprotect.
Site Recovery Manager checks for a valid license whenever you add a virtual machine to or remove a virtual machine from a protection group. If licenses are not in compliance, vSphere triggers a licensing alarm and Site Recovery Manager prevents you from protecting further virtual machines. Configure alerts for triggered licensing events so that licensing administrators receive a notification by email.
Site Recovery Manager and vCloud Suite Licensing
You can license Site Recovery Manager individually or as part of vCloud Suite. You should consider the licensing and integration options that are available to you.
When products are part of vCloud Suite, they are licensed on a per-CPU basis. You can run an unlimited number of virtual machines on CPUs that are licensed with vCloud Suite.
You cannot mix license types. For example, you cannot protect a certain number of virtual machines by using per-CPU licenses and other virtual machines by using per-VM licenses.
You can combine the features of Site Recovery Manager with other components of vCloud Suite to leverage the full capabilities of the software-defined data center. For more information, see vCloud Suite Architecture Overview and Use Cases.
Not all features and capabilities of vSphere are available in all editions. For a comparison of feature sets in each edition, see http://www.vmware.com/products/vsphere/.
Site Recovery Manager Licenses Required for Recovery and Reprotect
You have a site that contains 25 virtual machines for Site Recovery Manager to protect.
For recovery, you require a license for at least 25 virtual machines, that you install on the protected site to allow one-way protection from the protected site to the recovery site.
For reprotect, you require a license for at least 25 virtual machines, that you install on both the protected and the recovery site to allow bidirectional protection between the sites.
