Support and Limitations

VMware Storage Support and Limitations

• Incremental data synchronization is not supported for virtual machines with version 4 (only full data synchronization is supported).
• Data synchronization for disks larger than 2TB is not supported under ESXi 5.0 and 5.1 versions (single disk capacity < 2032GB).

Sync Proxy Network Requirements

• A Ubuntu 20.04 system with a minimum of 2 cores and 4GB of RAM is required as a Sync Proxy node.
• Access to the vCenter management network address and port is required.
• Access to port 902 of ESXi managed under the vCenter is required.
• Access to the management network address of HyperMotion/HyperBDR Console is required.

Sync Proxy Performance

• The maximum number of synchronized hosts per Sync Proxy is limited to 100.
• Sync Proxy rate configuration is related to the number of concurrent synchronized hosts:
  • (Default Setting) When a higher rate is required, it is recommended to adjust vmware_release_cpu_time = 0 to improve synchronization efficiency.
  • When there are many concurrent synchronized hosts, it is recommended to adjust vmware_release_cpu_time = the number of concurrent synchronized hosts.

Guest OS Support and Limitations

• Virtual machines using remote RDM disks (directly accessing a storage LUN in SAN) are not supported.
• Network-shared mounted directories (e.g., accessing data through NFS/NAS in the virtual machine system via remote network) are not supported for synchronization. Use a file synchronization tool for this data.
• Independent-mode virtual disks are not supported and must be synchronized as basic disks.
• Virtual machines mounted with USB or PCI peripherals will fail to snapshot (e.g., encrypted dog devices, etc.).
• Virtual machines configured with shared disks need to change the shared disk to non-shared mode (modify the parameter iscsi1:0.sharing to mutil-write and change it to FALSE).
• Virtual machines mounted partition must have more than 100MB of remaining availble space (e.g. Linux: /var,/boot/ or others partition. Windows: C:).
