Needing advice on RAID Controller for home SAN

I would appreciate it if those who have a setup like I'm requesting would chip in some information.

I currently have an old PC (core 2 quad q6700 with 8gb of RAM, intel mobo) that I am using as a Hyper-V host. I only have 2 VM's on it due to the RAM limitation with this motherboard. I am using the onboard Intel RAID utility currently and I am powering 2 x WD Green 1TB drives and 2 x WD Blue 500GB drives. They are both running in RAID-0. I currently have no redundancy between the drives.

So... This is what I'm looking at doing. I am hopefully going to be replacing those WD green drives with 4 x WD Red 2TB. I am also looking at getting a hard drive cage to house them (see below).

The only thing that I am not sure about is a RAID Controller. I am looking to get a dedicated controller that will fit into an x16 or x1 (I'm not sure I have an x4) PCIe (v.1) slot, I would like to be able to use RAID-5 in the 4 drive setup for redundancy, and depending on cost, it would be nice to be able to connect up to 8 drives to it. Another thing that I think will be important is to be able to hotswap drives as well.

I'll be looking forward to your replies, and thanks in advance.

Its not clear if you are looking for a dedicated SAN/NAS or a simple raid for your Windows machine. I also can only speculate about your board.

For a dedicated highend NAS/SAN-storage solution you can

- use ZFS and software raid on Sata/AHCI ports (no need for hardware raid, works much better without)
- newest/fastest ZFS bits are from Solaris/ OmniOS
- for easy management, you can use webbased appliances (my free napp-it or NexentaStor CE). They are easy to install and to manage.

You can boot from a (16 GB+) disk or a fast USB stick - best as a ZFS mirror.
Hotplug may not work (you need to reboot to replace disks). Next step is a HBA like a IBM 1015 to add up to 8 disks with hotplug capability.

I am basically looking for high availability storage that I will use for a couple of hyper-v guests running on a server 2012 installation.

With ZFS, which I am not familiar with, will that integrate with server 2012? If I wasn't clear, I apologize, but the board I have does support raid, but I was wanting your opinions on weather to get a raid card for the added benefits of speed, reliability, etc.

Thanks.
 
I would see how it runs first with your current setup, and then adjust. It sounds like you want to just use one box with a raid card with Hyper-V, so really any raid card will work fine for you. LSI is a big name, most of their stuff is supported by Server 2012.

If you're running into RAM limitations with 2 VM's, I'm guessing storage won't be much of a bottleneck for you regardless of how you set it up.
 
Thank for your reply. You are correct, I will be running Hyper-V on server 2012 with a couple of guests. The RAM is fine now, I don't think I'll need more ram especially once I move to a Core only install. Having said that, I would like to know some RAID card model numbers that you guys suggest based on the discussions in the thread. I would like to try and keep costs down as well, but with something that's pretty reliable and good support.
 
A (maybe controverse statement)

- such a controller is the best solution for raid-5 /6 on Windows but
- Raid 5/6 is slow regarding I/O (this is what you need for VMs)
- Raid 5/6 is quite insecure even with BBU (write whole problem) but on Windows, there is no better way like ZFS
- maybee WinRe FS may be an option some day for a secure storage but currently it is bad/slow by design

I would look at a cheaper Raid 1/Raid 10 controller without BBU and Raid-5/6 option, eventually think about SSD mirrors
LSI and Areca are the best options
 
Ok... so for ZFS, what i've read about it, seems like a great solution for just storage, but how would I be able to still keep Server 2012 and Hyper-V running? Should I have another VM set up in Hyper-V and configure ZFS and present storage that way? I'm not sure of a good way of doing it without using 2 different systems.

If your hardware is capable, you might consider running an all-in-one SAN/Hypervisor on VMware ESXi.

I'm converting each 6+ bay server at work into a host like this, running nexentastor as a guest on the hypervisor for a ZFS pool, which is then passed back to ESXi via iSCSI.

Lets you do something akin to RAID6 + zfs features for a pool for your vm guests.

There is a huge thread on how to get started in this forum for the "ESXi All-In-One".

I don't think that my board is supported for ESXi

It's an Intel DG33TL.
