XXXX XXXX TEKTRONIX DATACENTRES
With the rapid proliferation of connected devices and sensors, we’re generating more data than ever before and this trend is expected to continue. In a world of exponential data growth, it raises some challenging questions: where do we store it, how do we get it where it needs to be when it’s needed and how do we access it quickly to extract value from it? Tektronix’ Sarah Boen and David Akerson discuss the broad trends shaping the datacentre and wired communication market. BROAD TRENDS SHAPING THE DATACENTRE AND WIRED COMMUNICATION MARKET
T he digitisation and of data that datacentre managers have to comprehend has changed dramatically. In this timeframe, the industry has gone from talking about managing the flow of gigabytes of data to exabytes and zettabytes of data,” says Akerson. “This data has a tremendous potential to make businesses operate more efficiently and profitably and in some cases, provide new services to end users.” To date, extracting the value of this data in real time has been somewhat limited by technology. Over the next decade, Tektronix predicts new technologies will emerge, allowing organisations to better capitalise on the potential this data provides. A second trend in datacentre is PCI Express’ emergence as a storage interface. This has been driven by PCI Express’ performance advantage in providing data faster with lower latency, significantly impacting an organisation’s efficiency and profitability. To illustrate why storage is getting greater attention, Amazon did a study and sensorisation of data in an Internet of Things world has sparked an explosion in the amount of data created. “Over the last decade, the amount HOT DATA.

quickly with PCI Express Gen 4 (16 GTps) storage products in development and Gen 5 (32 GTps) on the horizon. To keep pace, the SCSI Trade Association announced its 24G Serial Attached SCSI (SAS4) specification.” NEW TECHNOLOGIES, NEW COMPLEXITIES Along with changes in storage and server technology, network communication technologies are going through similarly dramatic changes to provide faster data transmission. With these changes, the level of complexity has, and will continue to increase. A key challenge facing manufacturers is also the uncertainty of which technology to use. “There’s a sheer lack of clarity on what technology is going to work,
determined that every 100ms of latency costs it one percent in sales. Google determined that an extra 500ms in search page generation time dropped traffic by 20 percent. Another study showed that a broker could lose US$4 million per millisecond if his or her electronic trading platform is 5ms behind the competition. For these companies, legacy interfaces don’t cut it, prompting them to move to NAND based storage utilising the PCI Express interface. “Whether an organisation is storing data in the cloud or locally, the challenge of delivering large amounts of data with low latency will continue to drive advancements in storage interface standards and the introduction of new technologies” says Boen. “Storage interfaces and standards such as PCIe Express are advancing
