Virtualization and HPCC
Jun 2 2008, 3:00 PM EDT I agree with you that there is not alot of overlap where Server Virtualization and HPCC are part of the same solution. I just have one tweak to your first scenario where they might - just might - be able to coexist. If you had a scenario where you had completely different software requirements to run two different HPCC applications - but only one cluster. You could have a VM on each phyiscal server that was dedicated to one of the HPCC applicaitons. To then switch between the two, it would only be necessary to suspend one VM and restore the other VM on all of the physical servers. This would enable very easy sharing of a single cluster. I think is just an extension of what you had already stated, but I just wanted to throw it in for discussion. Todd 1 out of 1 found this valuable. Do you? |

RE: Virtualization and HPCC
Aug 7 2008, 4:23 PM EDT That's a very interesting idea. It's kind of a variation on the idea of creating the VM and loading the requested OS when a job runs. I'm not sure which one is faster (always a question that people will ask)? This shows my limited experience with virtualization, but when you suspend a VM, you would dump it to disk - correct? Then to restart the VM, you just restart it from the disk image? Not a bad idea. One sort-of drawback is that you need a disk in each node :) I'm a fan of diskless nodes since it increases uptime (you would be surprised what impact hard drive failures have on the uptime of systems - I wrote an article about his using data from CMU - it's amazing and it's totally indpendend of the disk type), saves money, saves power (a little). So it would be difficult to save the image to disk unless it's a centralized storage point. Thanks for the idea! It's very intriguing! Jeff Do you find this valuable? |
