Ok, So the idea on VM is to have plenty of Drive space? Please excuse my obvious lack of knowledge on VM but I am so old school just having a single server with just a few drives only running a few Apps like Httpd,mysqld,qmt-plus and dns. I have managed these for so long on just a couple of machines but technology is changing and we are growing as a company and I have heard and read great things that can be done with VM. I have another ibm Eserver with a couple of scsi 15k 50GB drives and 4 GB of memory that I can configure from scratch to do VM or what ever I need. I guess I should start by asking how VM is configured and How does allocate resources on the server? BTW I am a big fan of this list and have been for quiet some time. --Dave Les Mikesell wrote: > On 3/3/2010 2:40 PM, David Milholen wrote: > >> For example if i have 2 ibm Eserver 326 with dual xeon 2.8ghz each with >> 2 sata 200Gb drives. >> how many virtual machines can be configured on those to run a couple of >> mail servers and some network monitoring like ntop/nagios >> possibly add domain hosting services on there also? >> > > That's still not enough information to be useful since there can be > several orders of magnitude in difference in the load of servers like > that.
