Table 2‑1. Support for Data Compression Depending on Other Product Versions
Source ESXi host
ESXi Host that Manages the Target
Datastore Data Compression Support
Earlier than 6.0 Any supported version vSphere Replication does not support
data compression for the source ESXi
host, so the option Enable network
compression for VR data is disabled in
the Configure Replication wizard.
6.0 Earlier than 6.0 The ESXi host on the source site sends
compressed data packets to the
vSphere Replication server on the target
site. The vSphere Replication server
searches the target site for ESXi 6.0 hosts
that can decompress the data. If no 6.0
hosts are available for the target
datastore, the vSphere Replication server
uses the resources of the
vSphere Replication appliance to
decompress the data, and sends the
uncompressed data to the ESXi host.
6.0 6.0 This is an environment that supports full
end-to-end compression. The ESXi host
on the source site compresses the data,
and the vSphere Replication server on the
target site passes the data off to the ESXi
host where the host decompresses the
data and writes it to disk.
Data Compression and vSphere vMotion
If data compression is disabled, you can perform vMotion operations on replication source machines
between any pair of hosts that support vMotion and vSphere Replication.
When data compression is enabled, if both the source and the target ESXi hosts support data
compression, vMotion operations can be performed as usual. However, if the target ESXi host is earlier
than 6.0, vSphere Replication prevents vMotion from moving replication source VMs to that host because
it does not support data compression. This prevents DRS from performing automated vMotion operations
to hosts that do not support compression. Therefore, if you need to move a replication source VM to an
ESXi host earlier than 6.0, before you perform the vMotion operation, you must reconfigure the replication
to disable data compression.
