Support for 128 SCSI disks for Replication Gateway of hardware version 14
From version 3.6, support for 128 SCSI disks on Replication Gateway virtual appliance is provided. This should help in protecting more number of workloads and deploying lesser number of Replication Gateways. To have this support, Replication Gateway is shipped with hardware version 14.
Since VMware vCenter version 6.7 is introduced, virtual machine can have maximum of 256 disks per virtual machine with hardware version 14. If you require support for hardware version 14, download the Veritas_DataMover_VMware_Virtual_Appliance_67_support_4.0.0.0_IE.ova.
See Downloading the Veritas Resiliency Platform virtual appliances.
With Replication Gateway virtual appliance hardware version 14 following scenarios are supported:
Recovering VMware virtual machines to AWS
Recovering VMware virtual machines to on-premises data center using Resiliency Platform Data Mover without CDP

Table: Replication Gateway tunables
Replication Gateway tunables | Description | Commands to modify the tunables |
|---|---|---|
TRTcpWin | TCP Socket buffer size | /opt/VRTSitrpgw/pgsql/bin/psql srdb -c "update \"Gateway\" set \"TRTcpWin\" = 262144" |
MaxTRStreams | Number of TCP connection per Replication Gateway pair. All Replication Gateways in the Replication Gateway pair should have same values. | /opt/VRTSitrpgw/pgsql/bin/psql srdb -c "update \"Gateway\" set \" MaxTRStreams\"= 50" |
MaxTRFlows | Number of Update Set which can be transferred in parallel per Replication Gateway pair. All Replication Gateways in the Replication Gateway pair should have same values. | /opt/VRTSitrpgw/pgsql/bin/psql srdb -c "update \"Gateway\" set \" MaxTRFlows \"= 25" |
MaxARFlows | Number of Update Set which can be applied in parallel on the target gateway. | /opt/VRTSitrpgw/pgsql/bin/psql srdb -c "update \"Gateway\" set \" MaxARFlows \"= 128" |
