Software defined networking takes off

Datacentre, Wikimedia CommonsA report said that data centre and enterprise local area network software defined networking (SDN) is beginning to take off.

A report from IHS Technology said that the market for SDN Ethernet switches and controllers will hit $1.4 billion in 2015, double the revenues in this sector in 2014.

Cliff Grossner, a senior analyst at IHS, said in the first half of 2015 bare metal switches represented 45 percent of global SDN capable Ethernet switches.

White box vendors are number one in bare metal switch revenue. Dell owns 100 percent of branded bare metal switches, while HP has the largest share of SDN capable branded Ethernet switch ports.

In-use virtual switch ports will make up 11 percent of ports shipped by the end of this year. SDN physical Ethernet switches will represent 15 percent of Ethernet switch market revenues in 2017 – now it’s only four percent.

IDT launches chip to connect four displays

Integrated Device Technology has launched what it says is the world’s first DisplayPort based device which allows users to connect up to four monitors to a single DisplayPort connection.

The IDT VMM1400 multi-monitor controller is compatible with the VESA DisplayPort v1.1a and HDMI v1.3. It uses one DisplayPort input port and four HDMI or DVI output ports.

It also lets users connect up up to four monitors from a single digital output port. The output can be configured to be in expand mode or clone mode across four displays, which means users can shift between apps such as gaming, graphics design or spreadsheet analysis. Users can also dedicate each monitor to a separate application.

When configured for expanded resolution, the IDT VMM1400 can treat all attached monitors as one single monitor. When the user selects a display resolution that is the same or smaller than the original monitor’s native resolution, the IDT VMM1400 will send identical PC screens to each attached monitor.

In hub mode, the VMM1400 supports four HDMI or DVI outputs that can display on up to four monitors. In “daisy chain” mode, the ViewXpand device supports a connection to downstream devices – for example, another VMM1400 – to form the daisy chain of monitors compatible with the current DisplayPort standard. It is also said to automatically detect the number of monitors connected and adjusts the resolution accordingly.

Ji Park, vice president and general manger of the Video and Display Operation at IDT, said: “When you spread a PC or consumer platform across up to four screens, you can see more, toggle windows less, make clearer decisions, accomplish more work in less time and generally have an improved user experience.”
