WAN Sizing

When preparing your deployment, you need to verify that the connectivity between the two sites has bandwidth capacity that can handle the data to be replicated between the sites.

For minimum bandwidth requirements, see Zerto Scale and Benchmarking Guidelines.

Zerto Virtual Replication employs sophisticated compression algorithms to reduce the bandwidth required between the sites. While compression can be very effective in reducing the bandwidth requirements, its efficiency is dependent on data characteristics.

Note: Zerto Virtual Replication can also work with third-party WAN optimization and acceleration technologies, such as those supplied by Riverbed Technologies and Silver Peak.

Estimating the bandwidth requirements between the protected and recovery sites involves the following:

1. Collecting Data Characteristics for VMs.

2. Calculating the Estimated Bandwidth Requirement.

Note: When the recovery site is Amazon Web Services (AWS), you estimate the required bandwidth for the protected machines as described below.
