Technical question 2 x SAN

[Al-S]

For sure you can create a volume with 8TB size with Open-E, you even can create a volume with much bigger capacity from that. We have some customers who's have a one volume with size over 200TB.

For the dual controller, it should work, and trying the DSS as trial in your environment will give you the best result to be sure about all compatibility.

MSA1500 have i limit to max 2TB LUN, SCSI limit.

And you want to get a bigger storage, so the reason for the question if you could merge the LUN to a larger volum on DSS.

Then, should the performance be better with 4 x RAID 5 together?
