Hi,
We have a pair of riverbed boxes sitting on a dedicated 45mbps link. Right now, we are running riverbed without the SDR feature, which supposedly should further improve our replication speed and compression ability (as I understand, it will have reference points of data and etc, I might be wrong though).
Right now, we are pumping about 300-400mbps into the riverbed box and nearly utilize 100% of the 45mbps WAN link. When we enable SDR, we cut the utilization to about 20% BUT we realize that when we enable SDR, it actually slows down ingress traffic to the riverbed. Instead of getting 300-400mbps as without SDR, Riverbed is only accepting 100-200mbps of ingress traffic.
We are actually doing data replication. On the server side, we see buffers getting filled up because traffic is not going out fast enough.
Anyone of you engineers have any idea on this? Is this a known bug?
Initial findings from Singapore Riverbed engineers is that the read-write speed from Riverbed's own hard disks is the culprit that is slowing down and adding more overhead to the traffic (because of slow read-write speed), causing it to be slow. This is because we have a low latency link. The average latency is about 2ms on our link.
Is there any way we can fix and overcome this?
We have had this problem since a year ago and up till today, even with the new RIOS v4, the problem is still occurring.
Thank you in advance.
