WANop Turbo Charges Dell DR

Disaster recovery is a bit of a necessary evil in business. It’s one plan that you absolutely must have in place, but hope you never need to use.

Inevitably, though, in some way, shape or form, all businesses need to do some measure of disaster recovery at some point. It doesn’t take a tsunami or earthquake to knock out a server or hard drive at an inopportune moment, but when that piece of the system crashes the need to recover data can become critical…and when recovery of data is critical, the last thing an organization needs is a slow to recovery due to network bandwidth limitations.

Recently over on our Virtual WANop Marketplace forum, one of our clients (his user name on the forum is MattHelm21) posted about his experience with his organization’s disaster recovery plan.

He writes:

About 1 year ago, we deployed a Dell Equallogic PS6000 in our main office and a PS4000 in a DR location. We’ve also deployed VMware as part of our network strategy and replication of volumes on the storage arrays has been configured. Due to our somewhat rural location, inexpensive bandwidth is limiting us to about 2Mbps(upload speed) at the main site but unlimited(nearly) at our DR site. An IPsec tunnel between the DR and main site was put in place and the bandwidth above dedicated for that purpose.

Matt pointed out, however, that anything more than minor changes would “would choke the bandwidth.”

The answer for Matt turned out to be Silver Peak’s free virtual WANop solution, VX-X .

Matt writes that the improvement was remarkable:

The throughput improvement is huge. In some cases, I’m seeing 35Mbps. The minimum throughput I’m seeing during replication is 5Mbps. Again, all this with only 2Mbps of bandwidth.

He goes on to note that because of the VX-X WANop solution being added to the network strategy, where he previously had to prevent two volumes of information from going across the WAN to avoid “choking” things up, he can now easily allow five to occur at once.

“We are finally able to have all of our volumes(including those with SQL servers) replicate over the network and bandwidth for additional volumes is available,” Matt said.

Thanks Matt for the glowing endorsement.
