Display available space vs. expected available space
I'm running a 516 with six 6TB drives under RAID 5 after a factory reset. The available space (during the rebuild) says 27.7 TB, though I would have expected it to say 30 TB given the drives I have in place. Is this due to the web interface using TiB instead of TB, or is it the case that the available space will jump to 30 once the rebuild is complete and it reboots?

- 27.7 TB sounds about right, you cannot really get an exact number on the size of the disk. Let's say that the 6TB disk only has 5.8TB, check the link below for a better explanation.
http://knowledge.seagate.com/articles/e ... uage=en_US - A better way to say this:
Disk Drive manufacturers mean 1 000 000 000 000 bytes when they say "1 TB".
Most computer operating systems mean 1 099 511 627 776 bytes when they say "1 TB" This unit (1024*1024*1024*1024) is properly called TiB, but most people drop the "i".
This creates a lot of confusion.
Your volume should be about 30 000 000 000 000 bytes (minus a few GB for the OS partition and some overhead). That is 27.28 TiB. So this is just a units of measure thing - the available space will not jump to 30 when the rebuild completes. - Thanks for the explanations.
