    hi Chris ,

    I have a question about the script. Lets say we have limit the bandwidth to 1 mbps on office hours to save the WAN link bandwidth. As I know the vsphere replication uses the ESXi hosts vmk0 interface to send the traffic to the DR site VR appliance. so When we limiting the bandwidth of the vmk0 interface how does it affect to the vsphere HA heart beat traffic ?? .

    Well, script not working but close, we get “A limit of Mbps has been set on Replication”, somehow not passing the amount, such as 20.

    Any tips? Tried different ways below.

    PowerCLI C:\scripts> .\replication “vcsahq1.kembacu.org” “Replication” 200
    A limit of Mbps has been set on Replication

    PowerCLI C:\scripts> .\replication vcsahq1.kembacu.org Replication 50
    A limit of Mbps has been set on Replication

    Hello, VRA is not utilizing underlying infrastructure. We have 10gbps uplinks ,1gig link between source and destination NIOC is set to high for VR traffic, but still we get avg transmit data rate 2.5mbps. Though checked read cmd/s and its value goes upto 1300. No latency reported as DAVG/s is not going more than 20ms. Please suggest what tweaking can be done to increase transmit rate.
