In my opinion (as a 12-year customer), the 16TB limit is the number one deficiency in NetApp software at the moment, and perhaps their biggest deficiency ever. I would be very surprised if they weren't losing customers over this issue.
Acknowledged. I think they changed the limit from 10TB to 16TB with Ontap7, correct? Disc sizes are growing and growing - unless NetApp changes to solid state disks (flash), a higher limit would be nice to have.
BTW, I'm searching for a way to securely wipe out all data at our R200 disks. (ATA, 154x274gig) I wanted to build a big volume, but the 16TB hit me too. Has anyone ever played with 'dd' at Ontap side? Is there a hidden random device (/dev/random) I can use to create random data? Any hints? :)
acquire the /*free*/ disk_sanitization code.
WARNING: once enable, you cannot remove...short of zeroing your system
If you install this code, you can run:
disk sanitization start -d d<disk_list>
and it will write these bit patterns in this order to disk: 01010101 (0x55) 10101010 (0xaa) 11000011 (0x3c)
Once the disks are done, they are no longer in the spare pool but can be re-added easily.
Search NOW for more info.
