A minimum of 5Mbps of outbound internet is required.
The replication product behind SecondSite (Zerto) uses sophisticated data compression algorithms to reduce the bandwidth required between you and Zettagrid. Although this compression is very effective in reducing the bandwidth requirements it is highly dependant on the block changes to disk for each VM being protected by SecondSite. A minimum of 5Mbps of outbound internet is required.
That means we need to identify how many VMs that need protection and then use some sort of tool to determine how large a pipe is needed between you and the Zettagrid zone you would like your DR site in. The file below contains a PDF with instructions on how to determine the required connectivity with two options, one being a manual excel spreadsheet and one being a powershell script that can be run in your environment.
Zerto now also provides Zerto Analytics which includes the Zerto Resource Planner which can provide this information.
