IDC announced that IBM was number #1 in storage hardware (disk and tape combined)for 2006. Here are some excerpts from the IBM press release:
The newly released May 2007 report  by leading industry analyst firm IDC, "Worldwide Combined Disk and Tape Storage 2006 Market Share Update," shows IBM in the #1 overall position for all disk and tape storage hardware for the full year 2006.
In a total disk and tape storage hardware segment that increased to $28.2 billion in 2006, IBM captured 22.2 percent of the combined revenue for full year 2006, besting HP's 20.9 percent and EMC's 13.2 percent.
Five years ago, IBM was only #3 in this area, butis this new standing from IBM doing things better, or HP and EMC doing things poorly? Probably a little of both, but since it's not polite to point out the flaws of others in a blog, I will focus on what IBM is doing right, and I think our leadership in tape accounts for a good measure of this.
The resurgence of tape comes from a variety of factors:
- The focus on being "green", to conserve energy power and cooling costs. Tape is the cheapest storage in this regard, as the tape cartridges only consume power when read or written.
- Government regulations where more data must be stored for longer periods of time, such as theFederal Rules of Civil Procedures (FRCP), Sarbanes-Oxley, SEC regulations, and so on.
- The widening gap in dollars per MB. Advancements in tape are outpacing disk. Disk is slowing down to about 25% improvement year on year, but tape continues its 30-40% improvement curve. A solution like Information Lifecycle Management (ILM) that moves older less valuable data from disk to tape can result in excellent cost savings.
- Exciting "combined storage" solutions like the IBM System Storage DR550 and the IBM Grid Medical Archive Solution (GMAS) that combine disk and tape with internal hierarchy storage management of data, based on policies.
