Considerations - VMware vSphere with Zerto Virtual Replication
Review the following considerations:
■ The following restrictions apply to recovering individual files and folders, and not to recovering the whole virtual machine:
■ The operating system of the machine on which the recovery site Zerto Virtual Manager is installed determines the types of file systems from which individual files and folders can be recovered.
■ When the recovery site Zerto Virtual Manager virtual machine operating system supports a file system, files and folders can be recovered from this file system in virtual machines that this Zerto Virtual Manager will manage the recovery of.
For example, if a protected virtual machine running Windows 2012 has files using the ReFS file system and requires one or more of these files to be recovered and the recovery site Zerto Virtual Manager is on a machine with Windows 2008, which does not support ReFS, the protected virtual machine files and folders cannot be recovered, but the whole virtual machine can be recovered.
■ You cannot take snapshots of the Zerto Virtual Manager while the Zerto Virtual Manager service is running. Doing so can cause operational problems for the Zerto Virtual Manager, such as inconsistencies between the Zerto Virtual Manager on the protected site and on the peer site.
Routable Networks
The Zerto Virtual Replication architecture supports the following network configurations:
■ In on-premise environments:
■ Flat LAN networks
■ VLAN networks, including private VLANs and stretched VLANs
■ WAN emulation
■ VPN IPsec
■ In Cloud environments:
■ The instance (virtual machine) on which the Zerto Cloud Appliance is installed must use a subnet that is accessible from all Zerto Virtual Managers that may be connected to this instance.
The Zerto Virtual Replication architecture does not support NAT (Network Address Translation) firewalls.
Minimum Bandwidth
■ The connectivity between sites must have the bandwidth capacity to handle the data to be replicated between the sites. The minimum dedicated bandwidth must be at least 5 Mb/sec.
The Zerto User Interface
■ Zerto recommends using Chrome, Firefox, Microsoft Edge, or later versions of Internet Explorer.
■ Microsoft Internet Explorer 10 and all versions below, are not supported.
■ The minimum recommended screen resolution is 1024*768.
