Data Domain Inc., a provider of deduplication storage systems, announced Monday the Data Domain DD880, a high-performance inline deduplication storage system for enterprise backup and archive applications.
With aggregate throughput up to 5.4 TB/hour (terabytes-per-hour), faster per controller than conventional virtual tape library (VTL) systems, and single-stream throughput up to 1.2 TB/hour to enable protection of large databases in short backup windows, the DD880 establishes consistently high benchmarks across the spectrum of common data center backup metrics.
A DD880 system supports up to 71 TB (terabytes) of associated addressable, post-RAID (redundant array of independent), pre-deduplication disk storage. Read the rest of this entry »
Mono—the open-source runtime for .NET applications—is stealing some of the thunder from Java applications for the Linux desktop. Recent Linux distros have featured new .NET consumer applications that run under Mono. Part of the reason is that the distributions contain up-to-date Mono development tools, while their Java tools are obsolete.
“We have seen a real spike in Mono [application] development for the Linux desktop over the last two to three years,” said RedMonk analyst Stephen O’Grady. He cited Mono applications, including the Banshee music player, the GNOME Do desktop search tool, and the tomboy note-taking application as examples of Mono applications that have no Java counterpart equivalent in popularity.

Is Hadoop the cloud’s killer app?
Posted on: July 20, 2009
It’s named after a stuffed elephant, but the Apache Hadoop project is no toy. It’s designed to handle the largest datasets in the world, as well as perform the double duty of both cluster management and distributed file system. Developers in enterprises around the world have been building such systems from scratch since the dawn of grid computing, and with Hadoop approaching version 1.0, an alternative is at hand.
That’s not to say that Hadoop is without warts. For the past three years of formal development, the project has consistently broken backward compatibility, and many users have cited security as an ongoing concern. But Hadoop creator Doug Cutting, also an employee of Yahoo, says that both of these issues should see solutions in the next two releases.
Mike Fitzgerald, COO of Adknowledge, said that his company has been using Hadoop for almost a year now. His team runs Hadoop in Amazon’s EC2 cloud, but it uses its own implementation rather than Amazon’s official Hadoop services.
Adknowledge uses its Hadoop cluster to sift through customer data to determine which ads are best suited to which customers. He said that, on average, his team’s Hadoop cluster sifts through approximately 40 terabytes of data at a time in a batch job. Read the rest of this entry »
