The performance characteristics of your Portability Suite product depend on a number of factors, including:
Hardware and software profiles of your source and target
Hardware and software profiles of your Portability Suite Server host
The specifics of your network bandwidth, configuration, and conditions
The number of your source workload volumes and their sizes
The number of files on your source workload volumes (file density)
Source I/O levels (how busy your workload is)
The number of concurrent migrations and the number and type of the targets
Whether data encryption is enabled or disabled
Whether data compression is enabled or disabled
For planning large-scale workload migrations, you should perform a test migration of an average workload and use the result as a benchmark, fine-tuning your metrics regularly throughout the project. In addition to the data transfer process, also consider the other phases that a conversion job goes through, as applicable to your project:
Preparation and network setup
Source workload and target machine discovery
Target configuration
You can set up multiple workload migrations and run them simultaneously. Scalability testing performed with VMware ESX hosts suggests the following benchmark recommendations:
Multiple conversions to a single VM server: no more than 20
Multiple conversions against multiple VM servers (ESX): no more than 30
