Hello Greg, 1) Is there a limit to how many MD1220's can be connected?  With the MD1220 you can put a max of 4 Enclosures can be daisy chained together (giving a total of 96 drives per SAS port).   2) Once virtual disks have been created across my original 6 devices, is it possible to resize or add to that configuration?  Or would I be required to blow it away and recreate? You can add drives to your virtual disk and can expand the size but depending on how much space you are adding it can be faster to backup the data and then recreate the virtual disk & restore your data.  The expansion of a virtual disk is really slow and can take weeks if not months depending on the size of the virtual disk.   Please let us know if you have any other questions.
I am looking to add 6 new MD1220's to a present configuration of 6 which are daisy chained.  Two quick questions on this... 1) Is there a limit to how many MD1220's can be connected? 2) Once virtual disks have been created across my original 6 devices, is it possible to resize or add to that configuration?  Or would I be required to blow it away and recreate? ThanksGreg
