Albireo can be implemented in one of three ways, Floyd said.
When used as inline dedupe processing, it does the comparison to previously stored data before storing the new data. Floyd said there is a slight latency when using Albireo as an inline process. However, he said, it is the easiest way to implement the technology to storage arrays, and so this may be the first to be implemented by OEM vendors.
The second method is post processing. Using post-processing, the original data is copied directly to the target array, after which it goes through the dedupe process.
The most efficient method is parallel processing, in which the dedupe process is applied while data is still in memory before it is sent to the hard disk drives, Floyd said. “But there’s more work to integrate it this way,” he said. “Vendors might not want to start with this technology.”
Permabit is currently working with a number of primary storage vendors to integrate Albireo into their arrays, Cook said. He expects some of those vendors to roll out new arrays with the Albireo technology by late 2010 or early 2011. He declined to name specific vendors.
Albireo’s primary competition is expected to be deduplication technology from NetApp, which dedupes primary storage to NetApp arrays, Cook said.
“They’ve done a good job with it,” he said.
