\u00a0It\u2019s coming, it\u2019s really coming, and it\u2019s going to be huuuuugggge!<\/div>\n<\/div>\n

That was the message of the tech company executives keynoting the annual Open Compute Project Summit<\/a>, held this week in San Jose, Calif.<\/p>\n

They were talking about data. A tsunami of data. More data than anybody\u2014even in an era in which 300\u00a0hours of video is posted to YouTube every minute\u2014has yet seen.<\/p>\n

Before considering the challenges of this data deluge, the executives patted themselves on the back for launching the Open Compute Project in 2011<\/a>. They boasted that\u00a0it is leading to a far more adaptable and efficient infrastracture than would have been possible in an era of proprietary systems. And they welcomed several telecommunications companies, including AT&T, Verizon, Deutsche Telecom, and SK Telecom, that just joined<\/a> the consortium.<\/p>\n

Then they turned to their plans for\u00a0dealing with the coming wave of data\u2014driven by the growth of the Internet of Things and Virtual Reality\u2014that will soon hit the communications networks and data centers operated by companies like Facebook, Google, and Amazon.<\/p>\n

Mahmoud El-Assir, chief information officer for Verizon, said that\u00a0getting data quickly from the data center to the user will become more of an issue for virtual reality and things like connected cars, in which even small latency issues cause big problems. \u201cWe are moving to software defined networks,\u201d he explained, because, to serve VR and the IoT, \u201cthe current networks are impossible to scale.\u201d The future data center, Mahmoud said, will be small, unmanned, and closer to the customer.<\/p>\n

Kangwon Lee, senior vice president for R&D at SK Telecom, concurred, adding that,\u00a0\u201cVirtualizing the network gives flexibility and finer grain control.\u201d<\/p>\n

\u201cIf your customer [say, a gamer with a new Oculus VR] needs a lot of bandwidth,\u201d Lee said, \u201cwe can create a virtual pipe to that customer. For a connected car scenario, in which you want very low latency, we can route traffic at the edge of the mobile network.\u201d<\/p>\n

Jay Parikh, vice president of engineering at Facebook, pointed to Intel\u2019s Yosemite<\/a> server system on a chip and the new 100 Gbit Wedge<\/a> Ethernet switch as advances that will help cope with the coming data tsunami. Parikh indicated that the company is looking to artificial intelligence technology to help solve many of its other problems, but said that one frustrating bottleneck remains: storage.<\/p>\n

\u201cDisk drives are getting bigger, but not more reliable,\u201d Parikh said. \u201cLatency is not improving. Flash is getting bigger, but latency is only improving slightly.\u201d<\/p>\n

Urz Holze, senior vice president for technical infrastructure at Google, the most recent member of the Open Computer Project, is also looking for big improvements in storage.\u00a0 He called for disk manufacturers \u201cto think about alternate form factors and functionality for disks in data centers. Individual operators don\u2019t care about individual disks, they care about a lot of them tied together\u2014so there is a lot of room to save costs and complexity.\u201d<\/p>\n

Sony, it turns\u00a0out, was ready to answer that call. Later that day, the company exhibited for the first time its optical storage system designed specifically for data center use: the Everspan<\/a>. Horst Schellong, vice president of sales for Sony Optical Archive, said the system is a \u201cscalable, highly reliable product that stores data forever.\u201d (Well, at least what seems like forever compared with today\u2019s alternatives: Sony guarantees the archival disks for 100 years if stored under controlled conditions (under 35 \u00b0C\/95 \u00b0F);\u00a050 years otherwise.)<\/p>\n

The optical storage system uses a blue laser to read and write to optical disks (but Schellong emphasized that the format is not compatible with today\u2019s Blu-Ray disks). Each disk has two sides, with three recording layers on each side, for a total capacity of 300 gigabytes (the company has plans to increase this to 1000 GB). The drive reads and writes both sides simultaneously, using four lasers on each side, and has a peak transfer rate of 315 MB\/s. And each storage system includes 64 drives, for a data transfer rate, Schellong said, of 1 petabyte per day.<\/p>\n

The Everspan, it appears, does what Holze seems to want\u2014that is, offering expansion in an efficient way. One set of drives can serve up to 14 expansion units, each holding 680 trays with 64 disks in a tray, for\u00a0a total of 181 petabytes of data. The trays are collected and fed to the readers by two robots\u2014one to go and get the trays, and one to load and unload them. In other words, the system operates like a very smart jukebox. Sony will begin shipping Everspan systems in July.<\/p>\n<\/div>\n<\/article>\n<\/section>\n<\/div>\n<\/div>\n
