Are these technologies to improve storage utilization standard on most storage management solutions today?
Taneja: Well, they are certainly becoming standard. I would start with compression first. It is most popularly included in devices or software like backup software. So when you are doing backup, when the data comes into the backup software device, it is actually compressed and then put on tape. Many of the tape drives have built-in compression capabilities so the backup software can send the information in an uncompressed format all the way up to the tape drive and then the tape drive will squeeze it down. Data deduplication is relatively new and has just become popular in the last four or five years. And data deduplication is a very different concept — most applicable to backup-type information, where you are doing a lot of full backups from week to week and there’s a lot of commonality between week 1 and week 2’s backup, and it squeezes all of that kind of stuff out. In the grand scheme of things I would say that data deduplication has covered 10% of the overall data that exists in
