The next virtualization vendor on up in my series of posts digging down into CIO Magazine’s “10 Virtualization Vendors to Watch” is Marathon Technologies.
Here is what CIO Magazine has to say about Marathon –





How do you deal with planned and unplanned downtime in a virtualized environment? Marathon’s everRun HA (high availability) and everRun FT (fault tolerant) products have won acclaim including a recent VMworld Best of Show award for their ability to help IT ensure availability to end users. That award is even more interesting given that Marathon’s products today work with Xen virtual environments, not VMware’s. “VM high availability will be a significant concern in 2008 as virtualization technology improvements allow more high-end enterprise applications to run inside virtual machines,” Wolf says.

As stated by CIO Magazine, Marathon was awarded a Best of VMWorld award in 2007. This is a quote from Tech Target about Marathon and this award –





Other New Technology category award winners include Littleton, Mass.-based Marathon Technologies Corp. for its everRun FT for XenEnterprise, which will provide fault tolerance via software in real time for XenSource servers. The judges said this fault-tolerance capability will become more common to address concerns about reliability, and the technology opens the door for mission-critical apps to be virtualized.

I have posted about Marathon before (such as this post about the video interview from iForum and this interview with the CTO Jerry Melnick . Those two posts give you some background on the technology. Tarry Singh of Virtualization for Everyone did an interview with Jerry Melnick in January.



Recently Marathon Technologies has posted a demo video on YouTube.

Marathon’s everRun v-Available gives you the only fault tolerant solution for virtual machines, and it is designed exclusively for Citrix XenServer. Recently, Marathon published a joint whitepaper with Citrix that dives down into this solution . You can download the paper here. You can run the Marathon v-Available ROI Calculator here.





Pricing: The pricing on Marathon Technologies v-Available everRun for Citrix XenServer is $2000 per server. Here is the math for buying a complete solution with XenServer –




Citrix XenServer Enterprise licenses at list-

2 X $3000=$6000

Marathon v-Available at list –

2 X $2000=$4000

Total = $10000 

For $10,000 you get a fault tolerant server virtualization solution that provides true fault tolerance  AND maximum uptime for your virtual machines on XenServer.  You contact Marathon for more info.







Marathon clearly has an excellent solution to provide true fault tolerance for virtual machines running on Citrix XenServer. Many people do not realize that Marathon Technologies also has a solution for Citrix XenApp. Gabe Carrejo on the Field Readiness team at Citrix recently did some testing regaiidng their solution for Citrix XenApp and shared with me the test videos he created.

Gabe has done excellent work in working with Marathon to build this environment and to record his results. He broke his test out into eight different scenarios, and created short videos for each.

In this first video, Gabe shows XenApp sessions (the video was made before the name change, so still uses the Presentation Server name) maintaining the  connection despite a hard drive failure on the primary node.

-

In this next video, you see all the XenApp sessions over ICA stay up despite a network card failure on the primary server.

-


-

Next, Gabe causes the primary server to completely fail and the load to migrate over to the secondary server. No XenApp sessions are lost during this failure and migration.

-


-

Gabe then migrates the entire load back to the primary server with no session loss.

-


-

One final video I would like to show you from testing done by Gabe. In this test, Gabe simulates 39 user sessions using EdgeSight for Load Testing. He causes the server to fail and all the sessions maintain the connection. .

Here is a higher resolution version, but without the call outs (notes).

-


Gabe created additional videos where he simulated the failure of different hard drives in each server and a combination of hard drives and network cards. You can watch these additional videos at http://youtube.com/user/CitrixBlogger.

As you can see, Marathon Technologies provides a truly fault tolerant solution for both Citrix XenServer and XenApp (and to XenApp running virtualized on XenServer).
