I just want to give fair warning to anyone considering purchasing the Drobo b1200i. My B1200i has been unusable with VMware since I purchased it last fall. Drobo support has replaced the unit and controller cards, and has tried to resolve the problems but they have not been able to. I have Purchased a new Dell server for testing, new Intel Nics, and new switches, in addition to connecting the Drobo directly to the server. I also created a virtualsan using starwind, and ran VM’s which did not exhibit the issues I have experienced. None of these steps has made a difference. Development has also tried a new custom firmware. It appears that the Drobo b1200i may not be compatible with VMware ESXI (5.0,5.5,6) and/or Dell PowerEdge Servers and/or Broadcom and Intel Nics.
