I do like playing in the virtual world, but when it's on the air and making money, VM's can get expensive. Using the free ESXi option for instance, i'd have 2 if not 3 servers, and I'd want to be able to vMotion live VM's between the bare metal, that's not a cheap option at all.
I have 2 DL580 G7's with 4x e7-4870's and 256Gb of ram strapped to a 24Tb NAS for storage doing 35 automation systems, 10 "desktops" to do traffic and scheduling, etc, and it doesn't break a sweat in my lab.Granted it wants a LOT of wall power (each 580 has 4x 1200w power supplies!) But, with that hardware, theoretically, it could run upwards of 120 VMs before hitting a hardware limitation (mostly RAM limited). Now, just because you can, doesn't always mean you should. In this instance, i'd have no problem virtualizing the prod rooms and other things, but for the on-air playback, i'd think i'd keep those bare metal machines, just because it's a little easier to work with. (It takes a little brainpower to create a handful of vSwitches to schlep Axia around, file shares, plus keeping the VM datastore on it's own link.) It's not that it CAN'T be done, it's a question of should you do it. -- Alex Hartman On Thu, May 25, 2017 at 10:34 AM, Cowboy <[email protected]> wrote: > On Fri, 19 May 2017 12:50:57 -0500 > Kirk Harnack <[email protected]> wrote: > > > I'm considering going in one of two directions. > > Hey, Kirk... > > I'm going to suggest a third direction. > > We're running the network on 14 virtual Rivendell installations, > ( and one or two real ) and two servers. > It's all redundant and sync'd. > > The servers are nothing to write home about, but they don't have to be. > The virtual host machines are 8 core I-7's with 16G Ram and 1T > RAID-1, with two ASI Livewire cards each. > > A lot of bang for the buck, and not a lot to maintain. > ( compared to running each one discrete ) > Those disks are largely unused, but as disks go they're cheap, and as > this started as a bit of a science experiment we wanted to be sure > there'd be enough.
