Editor Sun Microsystems decided to purchase the Eagan, Minn.-based software firm LSC because of two complementary storage technologies which that company brings to the table, a Sun executive told searchSolaris. Sun's Director of Enterprise Storage, Bill Groth, said one of the main reasons Sun is buying the 40-person company is so it can get the rights to QFS, a file system which runs on Solaris, and SAM-FS, the archive management software that goes along with it. Sun has been working to ramp up its storage offering, and Groth said this acquisition is yet another step in that direction. Sun announced Friday that it is adding LSC to its long list of acquisitions (see related news article). Groth said other reasons Sun decided to go ahead with the $74 million stock-for-stock deal include LSC's strong engineering team and its customer base of hundreds of large companies with even larger storage needs. Some of LSC's clients include BMW, Xerox, Bristol-Myers Squibb and Hallmark. The beauty of QFS, said Groth, is that it plugs into Solaris just like any other file system, but it also offers unique capabilities that are geared toward customers with big storage requirements. "The file system is really designed around scalability and performance in that it can support file systems of 64 bits or 18.4 exabytes in terms of size," Groth said of QFS. "It also provides for data sharing between Solaris hosts so one physical file system can be read and written by a host and read by additional hosts across the storage networks. So it has inherent file and data sharing." From an architecture perspective, he said, QFS can separate actual data from the information about the data, or meta-data. What this enables, he continued, is the ability to move the data for back-ups or for performance tuning without impacting the application. Groth said the SAM-FS software integrates with QFS to provide an archive management function. It allows files stored within QFS to be migrated based on policy to different levels of storage. For instance, he said, a policy programmed into SAM-FS might dictate that files within QFS which are older than a particular date are to be automatically transferred to more cost effective storage such as tape. "The idea is that the user puts files into the storage system or file system and explicit back-ups are no longer required," Groth said. "It's all about separating the storage management functions from having explicit server ownership, and basically having them belong in the network and be managed by the storage system."
