Subject: [LSF/MM TOPIC] ZAC/ZBC Update
Date: Fri, 19 Dec 2014 15:40:49 +0100 [thread overview]
Message-ID: <549438F1.8070604@suse.de> (raw)
Hi all,
(my favourite topic again :-)
I'd like to give a short update for ZAC/ZBC implementation.
The T10 and T13 standards have been updated with some features
like SATA autosense which requires changes to the various subsystems
and the implementation itself.
These features would also allow for a simpler ZBC implementation,
but would require a more in-depth analysis of the filesystem
behaviour. Additionally the zone model has been modified, which
would require some changes to the block layer when formatting the I/O.
Also I'd like to discuss if and how generic filesystems could be
supported on ZBC drives.
Cheers,
Hannes
