Dear All,
Sorry maybe not the right thread. I would like to make a virtual server with two vm-s. It wouldn't be so complicated, because the two vm-s are: an sql server express 2012 on a win 7 pro (or win server 2012 depend on budget) and a special restaurant software on a windows xp (or win 7). The restaurant software now running on a windows xp with dedicated hardware, so I measured a lot of parameters, including cpu usage, disk usage, net usage. As for the sql express it will be a brand-new thing, so I can't make measurements, I can only count the vendors requirements, however I think its load will be relatively low. I read a lot of books and articles how to calculate the virtual cpu, and disk parameters. The only thing which make me confused is the disk system. Because of the budget we can't afford FCoE and ISCSI like disk system, so I can use only local disks. My question is how is it worth to make the disk system? I looking for the cheapest working solution so I thought of a single raid1 partition and install all things on it (i mean the vmware host and the two guests files on this same partition). It would be the cheapest, but I'm not sure this is the best or working one. I feel it would be better if I use separate partitions for each vm, or rather use separate disk for the vms. I don't know yet the required IOPS, so i would like to ask in theorethical which disk arrangement would be the best for me, that i can use for starting point when I have some iops.
Any suggestion is welcome.
thank you very much
