Should I use QOS for replicating over a vital link?

[Mark Mattix]

My company is planning to install remote disaster recovery equipment which will receive a replication from our primary. I don't have much experience with VMware but I was exploring and I found that under the performance tab of VCenter it looks like Vranger is using up to 70000 KBps (70 megabytes a second) on the link that's currently directly connected from our primary to DR.

What would you suggest I do with a DR that could peak at 70MByte a second and hold steady at 25MByte a second over a 30Mbit ( 3.5 Megabytes a second) internet link? This link is vital and all users need access to it. Would QOS be ideal, a dedicated line or is this just impossible with all this data throughput?

Thanks for any advice!  -Mark

My inclination would be to use QoS.

As a best practice replication traffic should be isolated on its own link. If replication traffic is going to occur on the normal links that user traffic exists on than QoS should be implemented to protect the normal traffic being being drowned out by the constant replication traffic.
