Transparent Snapshot Performance and Scalability

Review the following information related to performance considerations to scale your environment.

NOTE As a VMware infrastructure best practice, Dell Technologies recommends spreading the workload across ESXi Servers as much as possible. With the Transparent Snapshot Data Mover protection mechanism, you can move backup data in streams from mutliplie ESXi Servers.

Table 1. Scalability limits for the vCenter and ESXi Server
Component	Maximum limit
Number of protected virtual machines per ESXi Server	Unlimited
Number of VMDKs that can be protected per ESXI Server	1000
Size of VMDK	64 TB
Transparent Snapshot Data Mover (TSDM)	Up to 3000 virtual machine backups, and up to 180 concurrent virtual machine backups. NOTE An external VM Direct engine is not required when using TSDM as the protection mechanism for crash-consistent virtual machine protection. For application consistent and application aware virtual machine protection, add an external VM Direct engine.
