[Aoetools-discuss] Ethernet CRC-32 and Data integrity?

[David L. <ta...@gm...>]

Folks,

I've been looking at AoE and I'm trying to understand what affect the
Ethernet CRC-32 data integrity checking has on the AoE communications?
Particularly when going to GbE and jumbo frames support there seems to be
some data out there that there is a chance that the CRC32 won't detect the
error in the frame and with a protocol like AoE that error would most
probably end up being written to the target disk.

Has anyone done any analysis or have any response to AoE's ultimate
reliability for missed error detection of bad frames?

I think that there is a further problem to understand and that is with
network connection points. AoE is not routable but that doesn't mean you
can't use network switches to interconnect initiators with their AoE targets
and at these switches there seems to be a possible error point introduced
which AoE isn't protecting against? Are there best practices for AoE
installations to protect against these error points?
