RainStor releases next-gen big data repository

New RainStor 4.5 structured data repository adds 'intra column' deduplication capabilities

RainStor today announced the next generation of its online data repository. The update adds data deduplication capabilities and improved optimization for storing computer-generated historical data.

The new RainStor 4.5 version can run on a storage area network (SAN) or network-attached storage (NAS) system as a repository for structured data. The latest generation of the software is aimed at capturing and then serving up online transaction processing (OLTP) data sets, user log data and metadata.

The software comes with a resource description framework (RDF) interface to automatically join data from relational databases to the repository.

RainStor 4.5 adds "intra-column" deduplication, which is a single-instance storage feature that captures one copy of repetitive data and creates a pointer back to it for search queries. For example, online transaction databases may capture the same URL address over and over filling up millions of columns with repetitive data. RainStor will capture only a single copy of the URL and use it over and over when retrieving online transactions related to that particular online site.

"We're able to reduce the data footprint by 95 per cent because of deduplication," said Ramon Chen, RainStor's vice president of product management.

The product's user interface replicates a standard relational database management system versus a data warehouse. Thus, administrators won't need additional training, Chen said.

Unlike an Oracle or a SQL database, which are optimized to find a single record among millions, RainStor's repository pre-analyzes data it stores. The product places millions of related records in large blocks that can be quickly retrieved by a computer system's memory for faster search results.

"It's like a global positioning system. In the search window, you can type in the city or type in the exact address. An Oracle database will immediately search for an exact address, which can take a long time. With RainStor, it first gets you to the city, then it narrows the search down to the exact address," Chen said.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.

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.
