Hello Wade, With the ME4 it is designed to run multiple pools.  With your setup of 84x12tb drives it you would max out your pool size.  If you need to add any more drives other than the 84 you would need to create a second pool.  With the ME4 you can set it up as either Virtual storage or Linear Storage.  There are major differences between the 2 modes, & you can read about that in the administrator guide.    We don’t recommend using software raid on top of hardware raid. There is not a way to do create a single mount point natively on an ME4.  Please let us know if you have any other questions.
Hello everyone, I am looking between two choices here if I am to purchase a new storage, Scv3000 (plus an expansion) and ME4084. Our main application is scientific computing with steady writing and occasional yet large amount of reading. Current Scv2080 seems to get the job done without much incident. It looks pretty apparent that ME4 has lower specs comparing to Scv3000 but I wonder if there is any perceivable difference if we populate both of them with all NL-SAS disks as we did on Scv2080. Thanks!
ME4084 comparing to Scv3000 and existing Scv2080
