WAN Sizing Requirements with Zerto Virtual Replication
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.
You must use a minimum dedicated bandwidth of at least 5 Mb/sec.
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 protected VMs, for either of the following environments:
■ vSphere
■ Hyper-V
2. Calculating the estimated bandwidth requirements. You can use one of the following methods:
■ Estimating sizing using the Zerto WAN Sizing Estimator
■ Estimating sizing without the Zerto WAN Sizing Estimator
Note: When the recovery site is Amazon Web Services (AWS), you estimate the required bandwidth for the protected machines, either in vSphere or Hyper-V.
