I've read about HyperIP, SilverPeak, Riverbed, Cisco WAAS, and a few others to see how well they might improve Veeam Replication over the WAN. I currently replicate a few VM's across about a 10 MBit link, but I want it to be faster. Anyone have real experience with some metrics they could post?
A year and half after I created this post I have some data to share. One of my smallest clients wanted to do Veeam replication of a few VM's to a DR site. I setup Veeam at the DR site to pull the VM's from production. I just got it going last night and its still doing the footprint of some big VM's, so I don't have logs and stuff to share yet, but I wanted to share what I'm seeing already.
The production site is in a bad geographical area for telecom and has a cable modem with effective 1.7Mbit upload. The ping times are horrendous and the circuit gets hammered by users. I can replicate only at night. I throttle the replication in Silver Peak down to a trickle during the day.
The DR site has a 5Mbit down / 5Mbit up internet connection.
Over time, production will migrate to the DR site. Establishing reliable VM replication is going to be key to that migration.
I settled on Silver Peak as the WAN acceleration tool. They have had a virtual appliance option for some time, but only recently was there a big price drop in their virtual appliance vs. their physical appliance. I also really like how their smallest appliance will accelerate up to 4Mbits of bandwidth. This covers my SMB clients with crappy dsl, a full T-1, or 3 bonded T-1's. It makes it easy for me to sell and easy for my clients to add a little bandwidth without having to upgrade their WAN acceleration appliance.
I will add more detailed logs later, but this sums it up almost exactly:
Before Silver Peak: 1 GB per hour
After Silver Peak: 2 GB per hour
I got this rate by closely watching the datastore browser in vSphere client for several hours and watching the vmdk files grow.
I just realized that I still have compression and deduplication enabled in the Veeam job. I will play with these settings and report back. Silver Peak generally recommends that you turn off compression/dedupe in the source product if you can. Silver Peak self-reports its stats on how much it is helping. It is reporting about 50% reduction in data sent over the WAN.
