Replication bandwidth

[gregg_hughes]

Good afternoon!

We also have had poor performance on replication over a WAN/slow T1 connection. After perusing several postings relating to replication performance, I still don't have a clear picture on what the bandwidth parameter does in setting up a replication job. According to everything I've seen, the whole system, end-to-end, is limited by the slowest link.

So what does this bandwidth parameter do?

So what does this bandwidth parameter do?

My experience:

Suppose that the volume replication is running over 100 Mb/ network connection.
Usually DSS can provide the transfer speed much higher than 100 Mb/s.
That means that volume replication will take all available bandwidth of the network
connection, thus considerably slowing down any other possible traffic.

So, in this case setting bandwith to 5 MB/s will be a good solution. In this case replication
will only take 50% of the available bandwidth, leaving enough space for other network activity.

A note: It is only important during initial replication (or in other similar situations when a big amount of changed data must be replicated).
