Re: New Optical Form Factors for 400 Gigabit Ethernet
#12Does aanyone here work with consuming (not just passing it kn) these amounts of traffic? How do you manage to get anything meaningful out of it?
Can’t you saturate 100GB easily with a single disk array these days?

Not working on anything like that myself, but if the direction going forward it to stream not just 4k TV, but also 4k video games (console in the cloud), you will need some healthy backbones (even if they still run only IPv4 in 5 years!)

#14What are distance limitations at 400?
Trans-Pacific :) But more seriously, this article is about the device-side electrical interfaces -- the modules will transceive on any one of a number of physical interfaces depending on the specific needs (ultra-short-range for in-rack/in-DC, though that's a less likely application of this technology). Most multi-lane paths like these are using multi-strand optical cabling for short-range, and typically multiplexing the signal using on-board DWDM in/around the 1550nm band for two-strand long-range (which is primarily constrained by the power available to the module). This band is used because it can also be amplified inline (ref: erbium-doped amplifier) to extend the range.
(this is an oversimplification, I am not your network engineer, I am not a network engineer, consult a qualified network engineer in your jurisdiction)

#15I remember having to schedule a 780Kb download overnight and hoping no one picked the phone up. Or years later having to download shows in advance (illegally because they weren’t available) because streaming wasn’t possible. Now I casually (and legally) boot up any show I feel like within seconds at HD resolutions. I love thinking about the sheer amount of data that is traversing around the internet now. And it’s mor…
Multiplayer gaming has more issues with latency than a lack of raw bandwidth.
Not necessarily, depending on how the game is implemented a player with bad ping can be the only one who suffers the majority of the effects of their bad connection.
I am currently working with this tech:

And it does deliver on their promises, impressive stuff.

60hz even is low today by competitive standards for FPS games. 128 is nice, it should be a minimum.

In-wall cabling ends up being the limiting factor for a lot of this -- definitely check out the Nbase-T stuff coming out, which can negotiate from 1Gb up to 10Gb depending on what the cable can support (Ubiquiti just announced an AP using it, Juniper should have switches coming out this quarter IIRC).
10Gb ethernet works fine, but the power requirements for copper (base-t) are high and SFP+ is a bad standard for consumers (finicky connectors, low mating cycle rating, etc).

Often it’s only on LAN games for tourneys where the tick rate is that high. With internet latency or bandwidth requirements at that rate you are going to start dropping more and more packets and suffer from potentially more client side mispredictions.

Yes, I've worked with several that can do that. The interesting thing with disk arrays now is the controller heads are becoming the bottleneck.
You used to have many many shelves of SAS drives per controller pair, now the SSDs are so fast that the CPUs are saturated and you have to scale out, not up.

It's a fair question; I suspect most of the reason for the lag is that consumer internet connections rarely offer >1gbps, consumer LAN applications requiring >1gbps of traffic haven't emerged (for NAS/SAN, a directly connected USB 3 is probably the way to go for 10gbps transfer, which is what you're looking for here), and WiFi - how most people are connecting their consumer devices to the network - doesn't offer more than a gigabit of goodput in almost any consumer configuration. (e.g. 802.11ac with two spatial streams and 80MHz channels gets ~700mbps at MCS8)
That said, the NBASE-T and MGBASE-T efforts did consolidate to produce a 802.3bz standard that can carry up to 2.5gbps on a Cat 5e line and 5gbps on Cat 6, and we are starting to see consumer and SMB switches, APs, and NICs that support bz.
Moral of the story is wire for Cat 6 and look to upgrade to bz in the next year or so.
