NetApp FAS2020 aggregate capacity on ONTAP 7.3.1 – now 16TB

2 comments

My NetApp FAS 2020 Sizing post remains popular nearly a year after I wrote it. However, with ONTAP 7.3.1 (and later releases) out, it’s also out of date. Here’s current information from p. 33 of the ONTAP 7.3.1.1 release notes (NOW login required):

Beginning with Data ONTAP 7.3.1, FAS2020 systems support aggregates up to 16 TB raw capacity,
provided that the root volume is hosted in a dedicated aggregate (that is, one that contains only the root
volume and no user data).

The release notes go on to point out an alternative to the dedicated root aggregate – having two spare disks per controller.

It’s nice to see the FAS2020 finally getting a maximum aggregate size on par with the rest of NetApp’s product line. However, in an era where 2TB drives are available from Western Digital – and presumably other manufacturers before too long – ONTAP’s 16TB aggregate limit grows increasingly anachronistic.

Here’s a summary of what I know:
