Not a great comparison, the 10 gig switch is mostly SFP ports which are only useful for short run twinax or with fiber optic SFP modules for anything beyond twinax lengths. 10g copper SFP modules don't exist. Useful in a rack with servers with SFP NICs or if you want to fuck around with fiber, but in my mind that rates them as less useful than base-T which has much simpler and cheaper cabling demands.

I see a lot of twinax/optical deployments as converged core server + iSCSI storage but mostly in new cluster deployments where the expectation is everything is new and there's a few fiber handoffs or for core network deployments in larger networks.

But the most useful is always the base-T version because it drops in easily and handles pre-existing equipment with only 1g copper connections.

To be slightly fair with switch vendors, there is something complex about 10g-baset PHYs which makes them more expensive, but not THIS expensive for this long.

I still think IEEE messed up by not rolling variable (2.5/5/10) link speed into the 10g-base-t standard up front. It would have driven switches with broader footprints and driven more adoption by giving full speed where the cabling was good and 2-5x speed where cabling was just OK. More adoption, more unit volume and lower prices.

You mean it will cost a lot of money.

Vendors will end up playing games where the features you want won't be available unless you buy into their new product lines featuring 802.3bz ports at increased prices. Dumb, unmanaged 1 gig at today's managed 1 gig prices or managed L2/L3 802.3bz at the price you paid 5 years ago for 1 gig.

Server and desktop vendors will have a new upcharge option for 802.3bz ports that will allow them to hold the line on 10 gig port prices, and stupidly, many people will go for it thinking "bargain!" and we'll end up with a bunch of deployed 802.3bz as a sunk cost, further pushing out widespread adoption and the commensurate economies of scale and price cuts for 10 gig.

IMHO, this is a solution looking for a problem. Too much speed ot justify to the desktop and not enough speed to justify the price increase over 1 gig. If anything IEEE should have built this into the 10G-BaseT spec, knowing full well that the copper restrictions would hinder adoption and economies of scale. Had they put a variable signalling rate of 2.5/5/10 into the 10G-BaseT spec we'd be paying 1 gig prices for those ports now, instead of the highway robbery prices 10 gig gets now.

This will only be a useful spec if it replaces the commodity 10/100/1000 ports out there now and becomes the defacto baseline ethernet option.

I'm kind of struggling for what this is good for besides giving switch vendors a reason to push needless IDF upgrades and technology vendors yet another upcharge option.

1 gig Ethernet is already overkill for just about every desktop purpose and still has some useful life left in many data center applications, especially for lower performance areas, even in network storage.

The only place it becomes somewhat weak is in heavy use AC wireless deployments where it can be truly taxed, but most often even these deployments the vast majority of use reverts to the average of typical cabled clients.

It also feels like a reason to keep prices artificially high on 10 gig copper. 1 gig was sky high expensive when it first came out, but quickly became commoditized and very soon nearly everything came with 1 gig ports. 10 gig base T seems like it's been out for ages but prices really haven't dropped nearly as fast and I can't quite figure out why, other than it's fast enough to cut port densities by at least half while still providing 5x or greater throughput of 1 gig ports in most server deployments (ie, if you had 4x 1 gig ports and switch to 2x 10 gig ports, you have 20 gig aggregate vs. 4 gig aggregate and single stream throughput 10x the 1 gig solution).

And as usual, vendors can't stand the idea of the customer buying half of what they did before and getting 5-10x more value than they used to.

I guess the new standards will be great, but only if they replace 1 gig wherever you used to expect 1 gig, ie, everywhere. Otherwise it's either irrelevant or a new way to pay higher prices for 25-50% of the performance you should be getting out of 10 gig at the price -- or higher -- you ought to be paying for 10 gig these days.

Comment Re:Yay! Sharepoint! (Score 2) 44

My guess is that MS really wants to kill of basic (SMB) file sharing. The protocol is open enough that world+dog has already implemented in everything, so every file server upgrade faces the prospect of losing out to something else -- shit appliances all the way up to big ticket EMC devices.

Trying to move everyone to Sharepoint has so many layers of lock in I get dizzy just thinking about them. The endless licensing sales for server, SQL and 3 different kinds of CALs. Relentless sunk costs of developer time and migration. Files sequestered away in a database unmigratable to competing file sharing platforms.

It's a perpetual motion machine of IT spending, right up to and including Office365 hosted migrations once the painful costs of adopting and infrastructure become realized.

I've never understood the attraction to it. I work at an IT consulting firm that sells Sharepoint services and our site is a complete joke, used mostly as a way to host OneNote notebooks.

How could you call yourself culturally aware and not know of the Dead Kennedys? While "cult" stars at the peak of their performing career, they remain a defining element of punk rock music.

They and their lead singer Jello Biafra made the national TV news when they were charged with "obscenity" for a poster included in their albums. Tipper Gore, Al Gore's wife, a critic of "offensive" rock music, sparred with Jello.

In Minnesota user fees (of which gas taxes are just a subset) doesn't cover the maintenance cost of the roads and less than half the total cost of the roads. And the bitching about deferred maintenance and delayed capital spending for roads is endless.

Politically you would never get away with the $2-3 in statewide tax increase directly funneled to mass transit. The people who don't or can't use mass transit (ie, they live hundreds of miles from it) would never agree to a huge gas tax and the $4-6 increase you would need to impose on people who *could* use it in metro areas would be an economic disaster for almost everyone and a political impossibility.

If you imposed a metro-area transit gas tax of $5/gal to meaningfully fund transit improvements it would jack up my personal fuel expenses by 300% and I drive barely 10,000 miles a year.

I could probably afford it financially, but the reality is almost all of my driving for work to client sites is impossible *now* with mass transit -- and I live in the city and have clients in the city. The schedule and timing is not remotely viable for that, let alone reverse commuting to some suburb on a schedule designed around driving.

Explain to me the difference, if any, between Palmer 'retaliating' against Clinton, and Insomniac 'retaliating' against Palmer.

ANY claim Palmer can make to 'free speech' must also extend to Insomniac. Any claim Palmer makes against Insomniac must also apply against Palmer. Either both Palmer and Insomniac have the choice of who to associate with, who to engage in commerce with, and to attempt to sway others to similar thinking, or either of them can.

Apple's dictation software (PlainTalk) was running on System 7.1 Pro 20 years ago, using local hardware 100's of times slower than what I have in my pocket. Basic NLP code was running on the Newton, which was 1000x slower and still managed to handle the basics on top of the handwriting recognition. "Speakable Items" let me run user-writable AppleScripts to automate tasks and was just missing dictatable variable names.

I always thought the Netware IPX/SPX network numbering system was quite clever -- 32 bits of network addressing and a 48 bit node address, usually based on MAC addresses.

I always think of how much simpler IP would have been with a similar structure -- subnets could have scaled easily without renumbering or routing when common /24 limits were hit. The use of MAC addresses for node addresses would have eliminated DHCP for the most part or essentially automated it as clients would have only had to query for a network number, not a node address.

I'd take it more seriously if they were to directly power their data centers from renewables 24/7 only instead of some of the funny math of just spending more money to "buy" renewable energy from grid producers at a large enough volume to say they run on 100% renewable (or worse, carbon credits).

Because on the back end, they're still dependent in terms of actual consumption on grid baseload generation even if they have a balance sheet that says otherwise.

Further, trying to run full-time off wind+solar would require a substantial investment in energy storage to balance night/still air and storage is where we need the investment. And build-anywhere storage, not pumped hydro or other geographically dependent storage, either.
