Mellanox SwitchX-2 ASIC and its switches, not to scale

Mellanox pumps up channel for InfiniBand, Ethernet pushes

Switch and server adapter maker Mellanox Technologies gave Wall Street a bit of a shock with some cable issues and a big revenue shortfall in its most recent quarter and a projected one for the current quarter after one of its OEM customers bought more product in the latter part of 2012 than they could sell even into the first …

Drilling into a half-decent gigabit small-biz switch... from D-Link

Review I have a confession to make, dear readers. While I'm aware that this admission opens me up to virtually unlimited heckling from the Cisco-indoctrinated crowd, the truth of the matter is that D-Link switches have served me in good stead for over a decade. After having spent the past month reviewing D-Link's DGS-3420-28TC, I've …

The wireless card for the HP 10500/7500 modular switches

HP brings wired and wireless nets under single SDN umbrella

Wireless networks are becoming as important as wired ones for companies, and if you want to manage both and provide both wireless and wired functionality, it makes sense to mash up a hybrid switch that has physical and ethereal ports and is all managed by the same software stack. If you can slap a "software-defined networking" …
The BladeSystem c7000 Platinum edition chassis populated with blades

HP cranks up bandwidth on BladeSystem sheaths, adds pretty platinum stripe

When Hewlett-Packard launched the BladeSystem blade enclosures nearly seven years ago alongside its "blade everything" strategy, no one but Google was doing custom, high-density machines and it looked like blade servers would be the corporate platform of choice. And so HP built the c7000 chassis, and its smaller "Shorty" c3000 …

Arista wants to DANZ for high freaky traders

Arista Networks, the brainchild of serial entrepreneur Andy Bechtolsheim, is chasing a new market by reversing the polarity on its Ethernet switches, turning them into packet sniffers that feed into network analyzer equipment instead of packet shufflers. As is the case with most hardware these days, the trick is all in the …

Mellanox shoots higher and lower with long-haul switches

InfiniBand and Ethernet switch maker Mellanox Technologies, recently hammered because it missed its latest quarterly results big-time and gave a weak forecast for the first quarter, is sticking to its switched-fabric knitting and expanding its product portfolio, making good on its promise to flesh out a series of long-haul …

IBM rounds out 10GE/40GE RackSwitches with a switch hitter

Big Blue is rounding out its RackSwitch top-of-rack switches in conjunction with the launch of entry and midrange Power7+ servers earlier this week. IBM is kicking out two new switches, the RackSwitch G8264CS and G8264T, both of which offer a base number 10 Gigabit Ethernet ports and then additional uplinks or so-called " …
The big bad Nexus 6004 40GE fixed port switch

Cisco revs up Nexus switches to 40GE with fresh ASICs

Cisco has vowed to push 40GE Ethernet switches into the mainstream while also improving its 10GE/40GE Nexus boxes. The transition to 10GE networking is well under way, and the convergence of server and storage traffic onto switches continues apace, albeit at a slower rate than Cisco Systems had hoped. Despite this, the …

Juniper carbon copies sales and profits in Q4

If you squint real hard and tilt your head a little bit, you can see the difference between this year's fourth quarter at Juniper Networks and the quarter it turned in a year ago as 2011 came to a close. In the quarter ended in December, Juniper's product sales were down a barely perceptible two-hundredths of a point to $847. …
Mellanox SwitchX-2 ASIC and its switches, not to scale

Mellanox profits explode even as sales slip in Q4

Networking chip, switch, and adapter supplier Mellanox Technologies gave Wall Street a bit of a start earlier this month when faulty InfiniBand FDR cables caused it to miss its revenue estimates for the fourth quarter. But the company still turned in a record year and has squeezed a lot more profit out of its InfiniBand and …

Juniper to build its own software-defined networking stack

Juniper Networks is not, it turns out, all that enthusiastic about the OpenFlow technology that is at the heart of a lot of software-defined network (SDN) strategies these days. But don't be confused. That does not mean that Juniper doesn't believe in SDN or has not been quietly putting together its own SDN battle plan to take …
The Arista 7150S malleable 10GE/40GE switches

Ethernet sales fizzle, but self-aware networks set to explode

The switching and server markets are loosely coupled, just like the machines themselves in the data center. When one goes up or down, the other tends to either lead or follow, depending on the technology transitions underway in both markets at any given time. The server market is in a bit of a slump, and the Ethernet switch …

Cisco cuts costs, boosts profits faster than sales

After a number of other big IT players stumbled in the third calendar quarter, Wall Street was braced for a possible slowdown at networking giant and now converged-system supplier Cisco Systems. It seems that all that muscle tightening was for naught, because Cisco was able to do better than expected in the quarter ended in …

Mellanox stretches InfiniBand across campuses, metro areas

SC12 With InfiniBand on the march, taking market share away from Ethernet in the upper echelons of the supercomputer racket, Mellanox Technology could sit back and enjoy itself a little. But instead, the company is tweaking its InfiniBand lineup to make its switches and adapters more appealing and to keep InfiniBand rolling. The …

Big deals push Mellanox sales and profits in Q3

In the quarter ended in September, Mellanox posted sales of $156.5m, more than double that of year ago period, and the $48.4m in net income the company raked in was ten times--as in 10X--that of the black ink it had in the third quarter of 2011, when the Xeon E5s were expected but did not come out. The InfiniBand and Ethernet …

Juniper chops workforce by 5.3 per cent

In July, Juniper Networks reported a 50.1 per cent drop in net earnings for the second quarter and said that it would be restructuring as well as forming a partnership with Riverbed Technologies. We now know a bit more about exactly what they meant by "restructuring". At the time, Juniper – which has seen increasing pressure …

Sun men bump bellies in Cisco v Arista freaky trade battle

High frequency trading and certain parallel computing tasks need low-latency switches with as little jitter as possible, and they are willing to pay a hefty premium for those qualities. This was one of the founding premises of switch upstart Arista Networks, and Cisco Systems has revved up its Nexus 3000 series switches to try …

Arista touts next-gen switch as malleable as a T-1000 Terminator

Nobody has had his fingers in so much of the data centre pie as Andy Bechtolsheim, founder of Sun Microsystems, Granite Systems, Kealia, and Arista Networks. When Bechtolsheim and his team of techies at Arista say they have come up with their own way of doing software-defined networks (SDN) with their switches, people will stop …
