Help choosing replacement Hyper-V host machines and connected storage

You're correct, it's the opposite of what I need. I'm frustrated the purse-strings are more watertight than a frog.
Even with tight pursestrings, though, doesn't the MD SAN approach make it worse? The cost of the SAN PLUS the cost of the drives and all for nought since it doesn't accomplish any of the goals? If we were to skip all of the goals we could do lots of things for way cheaper.
Reducing power consumption and BTUs is most important.
I'm not opposed to having multiple Hyper-V host machines, but that would require twin servers for failover and load sharing.
Did I list each of the servers I'm currently using?

If you don't need redundant servers for high availability, then going down to a single R720xd or R730xd is all that you need. One server, only two CPUs. Fraction of the cost of what we have been proposing, way easier to manage, tiny fraction of the power that you are burning up today.

You listed two of them. Two R900s.

I currently have a Dell R720xd running Hyper-V 2012R2. It works really really well. Not sure on the price tag, but that is a nicely built system. Raid controller can do RAID 10, and RAID 6 in addition to the others... Add ram to meet your needs.
We have a monster R720xd with 128GB too. Sweet machine. R730xd has even bigger CPU options.
@scottalanmiller, @dafyre Which CPU and how much RAM is installed in your R720xd server?

Not sure on the CPU in ours. I know it is 128GB of RAM.

Does yours have the 2.5" or 3.5" drive option?

3.5". The 12 LFF plus 2 SFF option is really nice.

What is your concern with NL-SAS?

Are they fast enough?

Do you know the IOPs load you need to support?

Figuring out the IOPS needs is key. Without that we are guessing quite a bit.

I'll have to gather and calculate the info from our 3 SQL machines.
Does this page show the best way to determine current IO details?
http://www.sqltuners.net/blog/13-05-16/Measuring_Disk_IO_performance_for_SQL_Servers.aspxThe page suggested using the following select statement to obtain the required information.
SELECT
*
,wait_time_ms/waiting_tasks_count AS 'Avg Wait in ms'
FROM
sys.dm_os_wait_stats
WHERE
waiting_tasks_count > 0
ORDER BY
wait_time_ms DESC -
Thanks everyone!! I've got to leave for the day, I'll try and connect back to work later tonight.

Have a good evening, "see" you later.

Hello John,
In you case i think StarWind Virtual SAN will fit perfectly. Thus we are glad to offer you our NFR license. You can get it by filling in this form and providing a link to this forum thread in it.
https://www.starwindsoftware.com/starwind-virtual-san-for-mvp-mctUnfortunately NFR license will be provided to OP only (at least for now).

To be completely honest with all of you, we have not calculated the IOPS on our SQL machines.
This page has some tips (http://www.sqltuners.net/blog/13-05-16/Measuring_Disk_IO_performance_for_SQL_Servers.aspx) but is there a tool or PowerShell command which people normally use to collect the data?

If you're looking to buy Dell Equipment (even if you aren't) you can open the process with Dell, get their DPack and that will tell you your current usage.

Sweet, I'm looking into that right now. BTW, I really do appreciate how helpful all of you have been.
