Hitachi Data Systems fights 'rogue data' with new tool

Taking the rage out of search.

Hitachi Data Systems has announced tools to search unstructured data stored across a range of enterprise applications, including Microsoft SharePoint.

The software, called Data Discovery Suite (DDS), is based on technology from Norwegian search specialist FAST, to which HDS has added its own indexing capabilities. FAST is currently the subject of a take-over bid from Microsoft.

Speaking at the CeBIT trade fair in Hanover, COO Jack Domme cited figures showing that unstructured or semi-structured data, such as files or email, is far more common than structured data such as databases and is growing much faster.

"80 percent of data is not in rows and columns - and that needs new ways of thinking," he said. "Not all data can go through a tagging process, yet the real value in data is the ability to search it."

He called this "rogue data" and said that unless it can be searched, users cannot get answers to their questions and organizations will lose out as a result - especially if one of those searches is compliance-related, and the organization gets fined as a result of its inability to find the required information.

The DDS software searches data stored on Hitachi NAS servers and also on the company's Content Archive systems. In effect, it creates a common content store for all of an organization's applications. It is accessed via either a Windows Vista search widget or a browser interface.

HDS also announced new NAS systems at CeBIT, updating both its Essential and High-performance ranges. The latter is based on technology from BlueArc (which is part-owned by HDS) and now stretches to as much as 4 petabytes per storage pool and 1600MB/sec per node, the company said.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
