Speed, Speed, Speed

Who would've ever thought you'd see network performance like this on an Windows box:

This is the networking graph I got off of a physical box running the inital push for Quest vConverter's Continuous Protection option. The blip in the middle was it switching from the C: volume to the D: volume. It just about knocked my socks off - I've never seen anything eat up the entire NIC on Windows.

I found out some really cool stuff with vConverter. With the Continuous Protection option, you can keep a full-image copy of your physical server on an NTFS Share, ESX(i) Server, or Hyper-V server. After the first push, it just copies block (or file level) changes (whichever option you want) to the target store. This way, if you ever lose your physical box, you can either immediately pop it online in your ESX/Hyper-V box, or do a V2P back to your original hardware once it's back up and running. Very cool stuff.

Even cooler - let's say you're looking at Offsite DR. You already have Virtual Servers (VMware or Microsoft) in a hardened data center, and are currently replicating your VMs at your main office offsite to there. Good for you! Now how do you push your physical boxes out there?

With vConverter, you can do your initial copy locally (say to an NTFS Share on a NAS device), then you can take it to your Datacenter, and upload it to your SAN that your ESX or Hyper-V boxes use. Then go into vConverter, do a "change target" and select your ESX or Hyper-V box, tell it where the data is, and your good to go. Now all you have to worry about getting across the WAN is your block changes. Now you really do have an Offsite DR solution.
