Subject: impact of 4k sector size on the IO & FS stack
Date: Sun, 11 Mar 2007 18:51:53 -0400 [thread overview]
Message-ID: <45F48809.2060908@emc.com> (raw)
During the recent IO/FS workshop, we spoke briefly about the coming
change to a 4k sector size for disks on linux. If I recall correctly,
the general feeling was that the impact was not significant since we
already do most file system IO in 4k page sizes and should be fine as
long as we partition drives correctly and avoid non-4k aligned partitions.
Are there other concerns in the IO or FS stack that we should bring up
with vendors? I have been asked to summarize the impact of 4k sectors
on linux for a disk vendor gathering and want to make sure that I put
all of our linux specific items into that summary...
