Great improvements to scalability have been made in the recent release of The Unified Appliance – VSC/VP/SRA. The scale requirements will be different for the two different components VSC and SRA. This is because SRA works at the SRM level which has its own operational limits while VSC works at the vCenter level which has a different set of limits.
Before we get started let me 1st provide a quick definition table of the acronyms used in this article:
| Acronym | Definition |
| VSC | Virtual Storage Console |
| VP | VASA Provider |
| SRA | Storage Replication Adapter |
| SRM | Site Recovery Manager |
Results for SRA 7.0:

| Total number of virtual machines configured for protection using array-based replication | 5,000 | 2000 |
| Total number of virtual machines configured for protection using vSphere Replication | 2,000 | N/A |
| Total number of virtual machines configured for storage policy protection | 2,000 | N/A |
| Total number of virtual machines configured for storage policy protection with stretched storage | 1,000 | N/A |
| Total number of virtual machines per protection group | 500 | 300 |
| Total number of protection groups for array-based replication protection groups and vSphere Replication protection groups combined | 250 | 100 |
| Total number of storage policy protection groups | 32 | N/A |
| Total number of recovery plans | 250 | 250 |
| Total number of protection groups per recovery plan | 250 | 100 |
| Total number of virtual machines per recovery plan | 2,000 | 900 |
