RecoverPoint and Silver Peak

Hello.,

I have recently installed and deployed RecoverPoint in order to replicate from one of our remote office more than 300 Miles away between the two sites, using Silver Peak as a device that can improve communication between them. However, I have a couple of questions, since my replication is not performing as I expected.

In our first test, we are replicating a 300 GB device.

Bandwidth between the sites is 25 Mbits/Sec

I have compression (medium) and deduplication enable in my CG.

I have 24 hrs. RPO.

Source frame is a VNX and target frame is a XtremIO.

Set my CG as distribute group writtes across multiple RPAs

What type of tuning can I perform so I can get the best out of the Silver Peak, my RecoverPoint and my VNX. What settings do I need to look at so I can get the best performance. Should I do snap replication instead? What type of settings should I implement in Silver Peak?

Thanks a lot in advance for any info, hint or document that you can provide, it would be really helpful.

Hi there,

If you're using Silver Peak, make sure to have compression & dedup disabled on the RP side (CGs).

Is replication going into high-load?

Thanks, Zahid

Hi Zahid.,

Thanks a lot for replying to my post. I did disable compression & dedup on the RP side (CGs). Looks like these features needs to be disable in one side of the replica, it's either enable in RecoverPoint or Silver Peak but not in both appliances (source site). 

I'll monitor my replications and see how everything goes.

At the end the solution looks like is to disable compression & deduplication in the RecoverPooint side.

Hi Alexander,

Compression along with dedup is disabled per CG and it effects normal replication and any recovery activity. By allowing Silver Peak to perform the bandwidth reduction it offloads the CPU overhead from the RPAs which works in your favour from a throughput perspective.

Rich

Thanks to all of you for replying to my post.

The solution was to disable Dedup and Compression in the CGs, I let the Silver Peak to do work instead of the RecoverPoint.
