Units used in Replication Throttling?

Hi,
We want to throttle replication bandwidth.
In the Remote Site config in Data Protection, the option is to throttle B/W in MBps.  Is this Mbps (megabits per second) or MB/s (Megabytes per second)?  The unit implies megabytes per second (i.e. the "B" is capitalised), but that is normally a unit of throughput not bandwidth...
Obviously there is an order of magnitude in difference so its important we interpret this correctly!

Hi @AWatkins you will use megabytes here - as bandwidth can be expressed in bytes.

The Network Bandwidth is displayed as MB/sec which is referred to as MegaBytes.

    @AWatkins its unit of data replication throughput, so it is Mega “Bytes” per seconds.

    As per:

    https://portal.nutanix.com/#/page/docs/details?targetId=Prism-Element-Data-Protection-Guide-v511:wc-remote-site-wc-t.html

    “...you can define a policy that a Nutanix cluster should replicate data from site A to site B at less than 10 MBps between 9 a.m. to 5 p.m ...”. And also as you mentioned the “B” is capital letter.

    Hope this helps.

    Regards,
