Figure 8.9 Selecting the VHDs to use for the planner
Figure 8.10 shows an example of the process in action. The information from the tool
can be used with the Azure Site Recovery Capacity Planner tool, which is documented
at https://azure.microsoft.com/en-us/documentation/articles/ site-recovery-capacity-
planner/ to estimate more-detailed metrics around longer-term bandwidth and disk-
space requirements based on user-defined retention criteria.

Microsoft also has a performance optimization document at http://support.microsoft
.com/kb/2767928 that discusses registry changes that you can apply. One key setting
is MaximumActiveTransfers, which may be of interest if you are replicating a large
number of virtual machines. The default number of active transfers in Windows
Server 2012 R2 and Windows Server 2016 is six (up from three in Windows Server
2012); however, you may need to increase this per the article instructions if you have
many replicated virtual machines.
