Mellanox says 25 Gbps is the Goldilocks speed for flashy data flows

Enterprises are starting to roll 25 Gbps Ethernet into their data centres, and Mellanox is using this week's Open Compute Project (OCP) Summit in San Jose to plant its flag in the emerging market. The launch represents a chance for Mellanox to catch up in the high speed Ethernet market, having been outpaced in the 10 Gbps …

Confused by crazy crashes? Check your Linux kernel virtual Ethernet code

A chunk of code added to the Linux kernel to help inter-container communication turned out to mess up checksum handling on Ethernet networks. Described here, the bug was in veth (Virtual Ethernet). As the description notes, the coding error allowed corrupt packets to get passed to a veth device for delivery to the application …

Ethernet switch sales flatten but 40 Gbps starts to take off

The Ethernet market remains pretty dull: flat on a year-on-year basis, prone to quarter-on-quarter swings in individual segments, and dominated by Cisco. One vendor that can wave IDC's latest numbers in front of its investors is Juniper Networks, which piled on 39.4 per cent year-on-year, but at US$230 million for the quarter …

Broadcom builds better backbone for WiFi

Broadcom is getting ready for the arrival of 802.11ac Wave 2 in 2016, announcing a pair of chipsets for its OEMs. The two new chips in its StrataXGS range bring 2.5 Gbps Ethernet over Cat 5e cable, so as companies roll out Wave 2 access points, they don't have to pull new Ethernet cables. The BCM56160, targeting 24 and 48 …

Arista joins data centre 25/50/100 Gbps switch battle

Arista Networks has joined the race to get 25 Gbps Ethernet kit into hyperscale data centres. The company, a member of the cabal that last year kicked off the 25/50/100 Gbps effort along with Google, Microsoft, Broadcom, and Mellanox, has now lifted the cloth from a range of switches in leaf and spine form factors. Using the …

Evil computers sense you’re in a hurry and mess with your head

Something for the Weekend, Sir? Error 51: Consult service manual. Error 51? Is that supposed to be a joke? I mean, it sounds like a bad pun on “Area 51”. Oh, those wacky error-message coders on the firmware development team, they kill me, they really do. Let’s try again. Print. Error 51: Consult service manual. Come on, come on, don’t give me that. …

Does your company really need all that storage?

I was chatting not long ago to a sales guy from one of the big storage vendors. The market he serves is one of those where some of his customers buy a petabyte at a time – which I am sure he is happy about when it comes to hitting his sales quotas. The thing is, though, most companies have much more modest requirements. These …

Brocade targets SDN planners in campus switch range refresh

Brocade has announced a new bunch of campus switches, and with them support for new software defined network (SDN) features and a nifty ability to mix different switches in the stack as if they were all the same kind. While the press release tries to grab the eye with stuff like port density and speeds-and-feeds, the Switch …

Snakes on a backplane: Server-room cabling horrors

Twisted Pair The internet is not something you can just dump something on. It’s not a big truck. Nor is it a series of tubes. It’s an unimaginably large collection of computers connected by cables and radio waves. The more computers you have, the more cables you need. And that’s a problem. We’re now moving into the era of software-defined …

Broadcom targets terabit switch markets with fat StrataDNX chipset

Broadcom wants a bigger footprint in the router and switch market with the next iteration of its top-line silicon, the StrataDNX line. While conceding that merchant silicon isn't going to push Cisco or Juniper Networks out of the network core where the biggest traffic flows exist, Broadcom reckons the ability to support beyond …

Oracle finds a port in the SDN/NFV storm with two new ethernet switches

Who said Ethernet was dull? Oracle certainly doesn't: it's floated a couple of switches down the slipway and off into the oceans of the data centre. It's nearly refreshing to have something as vanilla as an Ethernet switch, sorry two Ethernet switches, announced among all the foam emitted by aspirant supplanters of the handful …

Interop lab cranks up speed for a 100 G Ethernet world

As standards bodies and vendors gear up for Ethernet to speed up all the way to all the way out to 100 Gbps, end users are also going to need confidence that their kit will do what it says on the box – and that it'll be interoperable. To that end, the University of New Hampshire's InterOperability Laboratory (IOL) has …
