Network restructuring advice

Wow, running off of desktops with no backups and they feel that they can't go down do to the criticality of the systems?
-
Probably want to be thinking about backups before thinking about anything else.

What is the total memory footprint of the existing "servers" and what is the full storage capacity of the existing machines and the Drobo?
The Drobo is a B800i with 12TB (10.91TB actual) 5.42TB usable, the other for "protection"
Memory is 16GB in the prolian, 2GB in the proxy and about 4GB in the email server.
Current application server stated 678.5GB storage capacity. Can't state the others atm, but given the age and that the are desktops I wouldn't but any bast 500GB -
Though segmented and long winded...
Scott is right.You need to establish the need for a backup. I'd use the drobo for a backup target. consolidate the other server functions on your actual server hardware using a hypervisor. ESXi, Hyper-V, XenServer etc... whatever flavor you like.

That is what I am considering at the moment, the problem is the current setup already has the data stored on the Drobo, so while it's already there, it isn't a backup as it's where the data actively resides.

The first step, outside of the technical, would be to begin building a business case around the needs to understand the risk aversion financially. Once you have that you at least have solid numbers to talk to the business about rather than feelings.
This can be difficult but try to get a number on downtime. How much money is lost per minute, per hour, per day... something to that effect. This may not be a consistent number, the first five minutes of downtime might be worth zero but the first full day quite a lot. It varies by company. And you must take into account mitigation - like outages at night, time to send people to lunch, working from paper, etc.
Getting this gives us a real means of understanding the needs for availability.
I'm still trying to accumulate this info as I explained to them that they would be able to afford some downtime, and the cost for HA need to be justified against their lost, however they are more concerned with having the system up and working whenever needed, which so far appears to be all day, every day, at any time.

@whizzard are you a consultant on this project or in house?
Expectations need to be discovered and defined before you can propose any sort of solution for them.

The setup is a bit messy, so as much as I want to consolidate what is currently there on proper VMs, some would require reinstallation, which and reconfiguration. I rather do that once and limit the amount of scheduled downtime.

not sure why you couldn't P2V. if flat files are being stored on the nas... easy peasy, move to whatever VM it belongs to post p2v. yes, down time will be required. Do it over the weekend, or over night.

In house, taking over from previous consultants. Their expectations, which the are adamant about is "everything just work" and they are concerned about the security of their data so backups are a priority as well.I just prefer to proceed with a holistic plan in mind that continue with the mosaic already there

Well, if that's their attitude....good luck. Of course we/they/everyone wants it to just work. But if they want it to "always work" that takes a good bit of work/planning/etc IMO easiest of which would be Virtualization either locally with colocation for DR or a pure virtual "cloud" fix. not knowing what the business is, application load etc makes it a little tough to recommend anything specific.

They are VM's already, but they aren't configured properly and software are installed across VMs

Is it advisable to mix HDD types in a RAID? i.e. SSDs with non SSDs?
-
you can.... but you're only as fast as your slowest drive.

It is not advisable to mix drives in any way if possible. You want absolutely identical drives in every way for optimum value, wear and performance. Even two drives of the same basic specs (size, spindle speed) is not as good as totally identical drives. You want all spindle and arm movements to align whenever possible.

I agree with Scott, to get them on board with spending the kind of money they might need to spend to get where they think they want to be HA wise, they will need to provide you with number related to how much downtime costs so you can show them that investing x amount of capital could save them from that downtime. Now, if you've been given a blank check to 'just fix it' that great for you for the moment, but you don't learn the proper process, and frankly, neither do they.
