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? David |
