Currently, this is simply a test environment / proof of concept for virtualizing our infrastructure, etc. Since I'm not sure exactly which current machines will get the P2V treatment, I'm not sure about IOPs. I have the link to the "how to measure IOPs in Windows" article, but I don't know what to run it on (we have an embarrassing number of physical machines).
You need to do it on all of them that you plan to virtualize. The StarWinds guys have access to DPACK, which you can install on all machines and then get a report on what your usage is on all sorts of stats.
So for this box, I want maximum local storage while remaining somewhat cost efficient.
Maximum? to what end? This still won't be cheap. Do you need 2 TB drives or 4? etc.
I have to show the bosses that these existing servers can be run virtually until they can be migrated to newer OSes or absorbed and decommissioned.
Just curious, what's the plan for this? to P2V each one and put them in production to show it works?
HBA to connect to the gi-normous DAS storage box we have.
SAN/DAS eh - well, if you have the need.
I guess I need to do more w/ DPACK, I've barely scratched the surface with it.
This chassis only takes 2.5" drives, and I'm not sure I want to go SATA just to get more storage. Systems will be P2V'ed and spun up on the hyper v host. 4.8TB / 128GB RAM should let me do 4-5 systems at a time.
As far as the DAS, it is already here, part of the production environment, but it has lots of empty space that could be allocated for VMs.

Since it's a test box, why not just purchase a SSD or two, unless you need a ton of storage for testing?
Our customer DBs are freaking huge, so much storage is needed. Besides a DC and Exchange server, most will be dev systems w/ big SQL databases. Besides, I want to have a badass test box for later.
Well in that case, you definitely can't buy anything until you know the IOPs of the SQL box that uses the most IOPs so you have at least that many when testing that box and keep things at the same level.
The heaviest usage SQL boxes will be the last things to get virtualized, I don't want to hear the bitching and moaning that will happen if 5ms of latency suddenly appeared.

OK switch gears - you are calling it a DAS - I'm curious when does DAS become SAN?

When it is networked.

When you use iSCSI and a network to get to it. These are directly connected, 12GB/s SAS cables, full tilt rock and roll. Only IP address is for the management interface.

If fiberchannel considered a network?

FC is a protocol. FC is DAS if it is direct, networked if there is a network.

DAS = Direct Attached Storage (e.g. no switch)
SAN = Storage Area Network (e.g. there is a switch) -
SAS, SATA, USB, IEEE1394, FC, FCoE, ATAoE, ZSAN.... none of them are DAS or SAN. All block protocols are both. DAS v SAN is how you use it.

I'm rejoining in the fact that I solved the non booting P2V 2003 R2 server.
I put the details into my main thread... but anyone just reading here - I ran chkdsk /f many times. after each try I ran fixboot/fixmbr from the 2003R2 install ISO.
It eventually fixed the MFT as needed and was able to boot!

@scottalanmiller No thanks, I'm good.

@scottalanmiller So, are you posting this because something happened while you were traveling? Suddenly, a wild lice appeared in Liesl's hair? Maybe that AirBnB wasn't such a great idea? Cleanliness is on par with their attitude regarding WEP?

Why you gotta be hating on WEP? I like having free WIFI.
