Worst case (may be different currently due to improvements
in ipmi<br>
stack) was about 10-15 minutes.</blockquote>

We have different issues on the SSH console though, we can
end up<br>
dropping chunks of console output under load (BMC CPU load
or high<br>
console usage).<br>

I think Jeremy can relive the trauma of heading into the TTY
layer, but<br>
I wonder if the solution here has something to do with
having a<br>
end-to-end flow control story.<br>

<div>I was looking in the spec and I saw that the packet
length for SOL is configurable in the session header, but I
didn't find the layout for the header. It's definitely not
configurable past 255B?</div>

Even though character data field is a variable length field, the
accepted character count in the SOL payload is a single byte. It is
based on the accepted character count that console acknowledges to
BMC and offset is changed. That is the 255 character limitation
mentioned.<br>

<div>It really doesn't sound like IPMI is well-suited to this
task. Tom, can you post a proposal for the OEM command
you'd like to see, or if you've tried one internally?</div>
</div>

I haven't tried this option, the OEM option is to bump the accepted
character count field. It will need changes on the clients (like
ipmitool).<br>
