*>>I'm not following the "single point of failure" * With a single host machine containing X guests, any failure of the host machine would render all X guests inoperable until fixed.
Best to have two host servers and split the guests between them. In the event of a hardware failure of one host, you could run the guests on the other. That's the config I now have for my home office... Frankly, with the arrangement you have listed, I would make sure to get (or end up with) two host servers that are similarly configured, and run the whole operation on them. For that size environment, SQL and Exchange will be fine in a virtualized capacity. I'd settle on a single hypervisor, though, for ease of management. iSCSI storage is not that expensive, and you can decide if you want the complexity of booting VMs off of it, or just using it for file/data storage. Lots of cost-effective vendors in this space to choose from. Then you'd be down to two physical boxes, plus external storage. *ASB **http://XeeMe.com/AndrewBaker* <http://xeeme.com/AndrewBaker>* **Providing Virtual CIO Services (IT Operations & Information Security) for the SMB market…*** On Wed, Jun 19, 2013 at 11:18 PM, J- P <[email protected]> wrote: > I'm not following the "single point of failure" > > this is what the end result will be -except the file/nas issue > > 1 Esxi host running 2 guets > > a) guest one win2012 dc > b) guest 2 citrix tx > > 2.windows 2012 dc physical (former DC/File/Print) > > 3.
