True, but with that much grunt on a school file server, only IT managers could spot the 5-10% drop off. In a way too, spare CPU cycles or HDD activity from any one virtual server are available for use by another. <br><br>I should admit that we have two core virtual servers so we can shuffle, mix and match processes between them to load balance, upgrade etc. Perhaps I should admit to a third virtual server in the fireproof strongroom as a backup server (blush).
<br><br>Worth adding that with less physical hardware, fans etc. this is a solution that will contribute less to global warming so we can all sleep better at night, dreaming of past times when we once shoved coal into the file server room.

My school is similar to Roland's and we have purchased 2 new servers this term (4Gb RAM, 1Tb RAID 10 SATA HDD etc) instead of purchasing 4 separate "real" servers. Less space is definite an advantage as we are running our of space in the server room. Our new moodle is running on a virtualised environment.
<br><br>BTW, our Moodle v1.81 plus has Moodle Networking activated at <a href="http://moodle.vermontsc.vic.edu.au">http://moodle.vermontsc.vic.edu.au</a>, anyone interested in trialing this with us???<br><br>Given the advantages outlined by Roland, however, with the current trend in virtualisation (I believe there are 3 types of virtualisations), and we are using VMware as well, I found that performance is slightly down compared to having a "real" server due to the intensive hard drive access. This might be an important factor for you to consider before moving to virtualisation!

<br>are already doing with file servers at school.<br><br>Instead of having a large farm or shelf with many assorted file servers, you<br>work with a souped up file server (s) .. with say 4 Gb, 1 Terrabyte of<br>raid10 x 4 HDD etc. You then run virtual file servers on this hardware using
<br>the free but very powerful VMWare technology.<br><br>Backups are as easy to do as scheduling to move the VMWare file to another<br>server or storage media, migrations involve moving this virtual machine file<br>then flicking the virtual start button. Each virtual server can even run a
<br>different operating system, as many as you want or need .. with say, a new<br>Moodle server to check out an upgrade, a backup proxy on stand by after you<br>fiddle about with some changes.<br><br>VMWare is free and in for the long haul. Google are an inspiration, already
<br>doing exactly this with their tens thousands of servers. I cut my teeth<br>playing about with the free workstation version. :-)<br><br>Regards Roland<br><br>On 19/06/07, Laurie Savage <<a href="mailto:sav@pvgc.vic.edu.au">
