Network interface cards (NICs) are often overlooked in server design. Their sheer ubiquity, combined with the ability to deal with most networking problems in software, can make them a component whose exact specifications are ignored. Some motherboard integrated NICs offer features such as jumbo frames and TCP offloading. These …
Recall the 21043?
That boring old chip was by concensus just about the best chip you could have. No great array of features, but it did what it did very, very well. Never gave up. That basic property is perhaps the most overlooked of all but is one reason why you don't put realtek anything in your servers.
Features, though, bit of a conundrum. Has anybody actually benchmarked the gain TOE provides? I recall some reports that the trouble of getting things just right to enable it actually cost more work than having the cpu do that bit of checksumming. The basic problem here is that without rigorous, thorough measurements such features amount to cargo culting and give rise to unreasonable price hikes.
Not saying they don't work or can't work, but I am very much questioning if this is something we've measured as opposed to taken it on faith or intuition. And that's before we start to look at systemic problems arising from poor choices earlier on in the chain.
I recall a 21040, and a 21140 and a 21041
21040 and 21140 and 21041 came from DEC, and were members of the Tulip family, and as you say "did what it said on the tin". They were also found on other folks cards too, later (I had one on a Netgear FA310, iirc, and on some no-name stuff via eBuyer, and...).
Is 21043 a relative? The usual search engine finds nothing much for 21043 NIC and related searches..
...tell the hypervisor to send all packets out to an external switch for processing.
Or maybe a better buzzword would be de-virtualisation.
What TLA is being planned for technology to tell the hypervisor to send all applications to an external computer for processing?
So it's true?
2 virtualizations equals a real?
Or as xkcd says "This shit just got real"
Any xkcd'ers out there know the link?
