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?

It crowns the latest in a long list of Ethernet technologies standardized by the Institute of Electrical and Electronics Engineers (IEEE) in their specification 802.3x. The 10GbE network o
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 […]
