Sun acquires assets of Cluster File Systems

Sun will acquire most of the assets of Cluster File Systems, which distributes the Lustre open-source file system.

Almost lost in the clamor over Sun Microsystems's expanded partnership with Microsoft on Wednesday was a small acquisition that will bolster Sun's HPC storage offerings. Sun agreed to acquire a majority of the assets of Cluster File Systems.

Among other things, Sun will get the Lustre File System, an open-source software distribution widely used in large computing systems. The company did not disclose the terms of the deal, which it expects to close around the start of Sun's fiscal second quarter, beginning Oct. 1. The acquisition will be immaterial to Sun's earnings per share, the company said in a news release. Cluster is based in Boulder, Colorado.

Lustre can manage and retrieve files on clusters with tens of thousands of nodes. Sun will make Lustre work on Sun's Solaris OS and will continue developing and distributing it for Linux and Solaris on multiple vendors' systems. The file system complements the Sun Constellation Architecture for HPC systems, Sun said.

The two companies aren't strangers. They have already worked together on several large clusters, including one at the Texas Advanced Computing Center with 1.7 petabytes of storage, according to the release. In July, Cluster said Lustre would start using Sun's OpenSolaris ZFS disk file system on Lustre servers that run Linux.

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.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
