I had heard rumors of 32 drives being the limit, so I figured, why not? I had more than 32 1.5TB and 2TB disks in hot swap bays, and could easily handle the connectivity. Plus, since I am booting the new WHS from a VHD, I knew that WHS could mount VHD’s meaning I could somewhat quickly test 32+ disks with VHD’s and 32+ physical disks, and also virtualized and standard configurations. See the below picture for what this looks like:
Here are a bunch of VHD's in Hyper-V that were used for testing
For those wondering, yes, Volume H is a raid 6 volume. No, it is not best practive to store that many drives that may be used concurrently on the same volume as it can be a nightmare from an IOPS perspective. My only goal was to test 32 drives in the WHS so I let it be.
The results on both old and new WHS boxes were the same, SCARY! The quick summary is if you have the need to run over 64TiB today, build a second WHS or something! Here is a quick summary of what happened when I installed over 32 disks on both the physical and virtualized WHS machines.
First I used the old WHS with 27 VHD’s and 10 “physical” disks (10x raid 6 2TB volumes):
37 disks in a WHS (10 Physical 27 VHD) yielded an error.
Then I tried installing 37 physical drives on the new WHS, passing through the MBR formatted disks to the WHS virtual machine running in Hyper-V:
WHS apparently does not like 37 disks as I soon found out
That is not something you want to see, ever, on a WHS that has data on it. I have backups, but copying TB’s of data is not fun.
Bottom line: I won’t be experimenting with more than 32 drives again anytime soon, or at least until WHS V2/ Vail comes around. It seems like the current version of WHS does not like that many drives.
Has anyone else tried over 32 drives in a WHS? If so, does anyone have workarounds for the errors encoutnered above?

Does anyone have the spd and sbr files from a Dell H200 Integrated not the adapter version? I am trying to get a 9240 to work in the integrated slot. Please post as it would be greatly appreciated. Edit: What is the command line to create an spd file anyways? Couldn't find it.
This week I received my first server equipped with 80Plus Titanium power supplies. For those wondering they offer in terms of power savings, at 115V the load/ efficiency ratings are: 10% load 90% 20% load 92% 50% load 94% 100% load 90% At 230v they are rated at 50% load 96% efficient. I asked about […]
The title says it all. I have a C6100 that I have loaded out with dual L5639 and 24 GB of RAM in all nodes. I have one node wired up to 6 bays running FreeNAS, but I want to expand my storage and add some ZIL/ARC SSDs. Option 1) Buy a SE3016 and a […]
Since it seems 15-20 of us got the awesome 846E1 deal, we collectively have 20-40 new sockets to fill! There is even the Intel 4 node deal spotted by @pyro_ on the forums so deals on barebones are coming. Maybe we can keep a thread on deals we find for processors? DDR3 rdimms too or […]
The big news this week is that the creditors of OCZ Technology have taken control of the company’s assets. OCZ Technology had consistently been unprofitable. That financial performance led to the dismissal of the company’s CEO and CFO recently. It appears as though the company’s creditors are now selling OCZ’s assets to Toshiba. This is […]

Understanding and managing graphics in a virtual environment is often very difficult. You have to deal with many layers of complexity between virtual machine and the workstations they are providing the graphics to. The bigger the environment, the more complex the graphics of the VDI (Virtual Desktop Infrastructure) become. Over the last few years, VMware […]
