IEEE Releases 802.3ba Standard
An anonymous reader writes "EEE announced the ratification of IEEE 802.3ba, a new standard governing 40Gbps and 100Gbps Ethernet operations. An amendment to the IEEE 802.3 Ethernet standard, IEEE 802.3ba, the first standard ever to simultaneously specify two new Ethernet speeds, paves the way for the next generation of high-rate server connectivity and core switching. The new standard will act as the catalyst needed for unlocking innovation across the greater Ethernet ecosystem. IEEE 802.3ba is expected to trigger further expansion of the 40 Gigabit and 100 Gigabit Ethernet family of technologies by driving new development efforts, as well as providing new aggregation speeds that will enable 10Gbps Ethernet network deployments."
You know networking exists outside of the internet, right?
Nah, thanks to DCE most storage will stay FC using FCoE. What this will do is eventually allow us to get to ridiculous port counts in top of rack and end of row switches and upload all that capacity without requiring a 6" diameter bundle of trunking cables. It will also allow 100Gb to be usable at metro distances since it only requires 4 pairs instead of 10.

I would rather have the adds and my 15Mb line, then my old 1200 baud connection to compuserve.
We only use 300 baud for internal stuff.

The original goal of iSCSI wasn't to avoid using Fiber, it was to avoid using Fiber Channel and requiring the creation of a second network, dedicated to storage, that is managed separately from the standard data network.
the original reason to go to iSCSI will be lost since fiber cables will have to be laid...
I'd guess your not aware that Fibre Channel runs on copper as well. This is cheaper and, therefore, common when distances are short. Here is Apple selling some.
The appeal of iSCSI, such as it has, is that it leverages relatively inexpensive and thoroughly ubiquitous Ethernet and IP infrastructure (switches and routers.) However, don't conflate Ethernet/IP with copper; there is a lot of optical in non-edge Ethernet.
iSCSI was never about optical verses copper.
Jumbo frames, dear boy. Jumbo frames.
Which have been around since 1Gb ethernet.
Tell that to my router... 20Mbps/1.3Mbps
Verizon FIOS here, my basic bundled rate is 25 Mbps/ 25Mbps. I could opt for faster
You are in a maze of twisted little posts, all alike.
But are we talking about 100Gb/s over copper or fiber?

Fibre and short-haul (~10m) copper, at least for the current standard. Historically, there's usually a lag of several years between a new Ethernet standard and a 100m copper version.
I'm a bit sceptical about folks who say they'll never be a copper version, because I've heard that tale often enough before. I confidently predict it will be the Year of Linux on the desktop before it's the year of Fibre to the Desktop.
They actually tried this with FireWire (IEEE-1394) in the consumer electronics industry back in 2000-ish, but then the whole HDCP thing came up, and that was that.
The idea is that you'd have a home theater receiver that just had a crapload of firewire ports on the back, and all your stuff would plug in via that, including speakers. Never happened though.
Slashdot still doesnâ(TM)t support Unicode after it was added to the HTML standard in 1997.
The standard includes specifications for copper. 40GBASE-CR4 for 40GB which specifies 4 lanes of twinax cable, and 100GBASE-CR10 for 100GB which specifies 10 lanes of twinax.
Surprise, surprise. Serial too slow? Try parallel!
The road to tyranny has always been paved with claims of necessity.
There's exactly one 4Gb copper FC card and zero 8Gb, the only use I've seen for copper FC is for connecting the bays back to the controllers, from there out it's always fiber optics.

Bow-ties are cool.
It's interesting how this will increase the adoption of iSCSI storage, yet the original reason to go to iSCSI will be lost since fiber cables will have to be laid.
That seems a tad disingenuous. The real reason for iSCSI was a
Microsoft price structure that made a network file service very
expensive unless it went in through the 'disk-on-SCSI-bus'
back door.
Linux and iSCSI was a way around the high cost of
a MS server/client system. None of the Linux-only or Macintosh
network systems were so encumbered, and worked
quite well without any iSCSI.
WTF are you talking about? Why was this modded up? Is it just because he's saying something negative about Microsoft?
I've worked in Microsoft Windows server environments for a decade, and I've never heard of SCSI specific MS licensing, or any kind of special licensing at all for file servers.
While it's true that a Linux server in general is cheaper from a licensing standpoint (hard to compete with free), that has nothing to do with iSCSI, SCSI, or FC.
The reason iSCSI is popular is because it's simpler to set up, halves the number of ports and switches required for a fully redundant server environment (minimum 2 ports and 2 switches vs 4 and 4), it has real authentication instead of the worthless "zones" crap in the FC world, provides user friendly names instead of numeric IDs, has encryption, 10Gb Ethernet can outperform even 8Gb FC, and even old 1GbE switches can perform adequately if port trunking is used properly.
What this all boils down to is that iSCSI is both better and cheaper than FC. Once popular SAN arrays from big vendors start to appear with 10GbE iSCSI as standard instead of an expensive "option", then FC will start to die a rapid and well deserved death.
I do not believe you've actually used iSCSI, at all.
The performance numbers are very different and so are the technologies, Microsoft filesharing is file-level and iSCSI is block level. It means with an iSCSI card, the machine can treat volumes as local disks and install any OS.
Secondly, you're confusing iSCSI with NFS. NFS has been freely available even back on Windows NT4. However it was not created to counter Microsoft, it was ALREADY there.
iSCSI until recently has been the only technology that provides block-level storage access and as efficiently as possible on a routable ethernet network. The recent FCoE is even more efficient but its not so easily routable.

Sorry to break it to you, but...
The image format changes the strip-tease.
BMP loads from the bottom-up. It's Sir Mix-a-lot's favorite format.
Progressive JPEG gets less blurry as it loads, simulating being drunk at a strip club.
There's no -1 for "I don't get it."
Twinax isn't too big, it's the bundle of 10 twinax you need to run 100gbit that are huge.
I'm a little confused, though. Cat6 is capable of 10GbE, so why not bundles of 4 and 10 Cat6 for the standard as well, instead of just twinaxial? I recognize you'd need a special port setup, but that would still be significantly smaller than twinax. They would then be capable of 100m, would they not?
