| | One booth I visited in the XenSource Pavilion is *[*Marathon Technologies*|http://www.marathontechnologies.com]*. I can recall recommending their high availability solution to a number of customers back in the late 90 when I was still an independent consultant. Back then, the solution was hardware and software based. Now, Marathon solution is +a completely software based high availability solution+ and runs on industry standard hardware. Marathon announced a new XenSource specific solution at VMWorld, and [won Best of VMWorld for New Technolgoies|http://searchservervirtualization.techtarget.com/originalContent/0,289142,sid94_gci1272002,00.html] . John Bara from XenSource (now part of the Virtualization Management Group at Citrix) said this about Marathon: |
| | |
| | By integrating everRun with XenEnterprise, Marathon is enabling customers of any size to get simple, enterprise-grade virtualization solutions with FT-class application availability, said John Bara, vice president of marketing at XenSource. is another example of how XenSource is working with partners to ensure XenEnterprise seamlessly integrates as the virtualization platform for a wide-range of high-performance, best-in-class solutions.\_ |
| | |
| | In the demo I saw, the v-Available everRun solution from Marathon was able to handle a failure of a hard drive one side of the link and a network card on the other side and continue running. Unlike many other virtualization HA solutions, Marathon solution does not restart the VM after a failure on one side of the link. The Marathon is always running and can handle the failure of a single component of either side, or an entire VM on one side without any downtime. It makes for a very impressive demo. |
| | |
| | That demo was of two servers on a LAN. The solutions also works over a WAN. I am still trying to get more info from Marathon Technologies to nail down what are the specific WAN requirements for this new offering. According to the Marathon FAQ the Split Site solution ( a different product) requires 10 ms of latency or less. Assuming has the same requirement, you cannot replicate a VM from a datacenter on the east coast to one on the west coast. According to a few docs I found on the Marathon website, the limit is 100 miles. |

| | There was a virtualization webinar last week with Marathon CTO Jerry Melnick, the CTO of Citrix Virtualization Management Group Simon Crosby, and Chris Wolf from the Burton Group. Here is the webinar [link|https://www.gotomeeting.com/en_US/island/webinar/provideEmail.tmpl?_sid=82510315%3A458B6D4DC1D5E92&Action=rgoto&_sf=2] . |

| | Marathon has an excellent High Availability solution for virtual machines running on Citrix XenServer. If HA is requirement for you, check it out. |
