IBM Debuts New Ultrium Tapes with Lower TCO by Timothy Prickett Morgan IBM has announced a new series of Ultrium tape subsystems and autoloaders for midrange shops. The Ultrium tape format was jointly developed by IBM, Hewlett-Packard, and Seagate Technology, and is based on the Linear Tape-Open that bears some resemblance to the Magstar technology developed by IBM, yet is incompatible with that Magstar format. The new IBM Ultrium drives can be attached to OS/400, Unix, Linux, Windows, and mainframe servers.
Like IBM's prior Ultrium 3580-H11 and -L11 drives, the 3580-H13 and -L13 Ultrium tape drives attach to servers through a normal SCSI peripheral connection. Both machines use Ultrium tapes with 100 GB of native capacity and sustained data transfer rates of up to 15 GB/sec. With 2:1 data compression activated, customers can cram 200 GB on a tape and see sustained data transfer rates approach 30 GB/sec. The 3580-H11 and -H13 models use a regular Ultra SCSI interface, while the 3580-L11 and -L13 use an Ultra2 SCSI interface. A second derivative of the LTO spec called Accelis, using a two reel format instead of the single reel in the Ultrium design, and loading from the midpoint of the tape (both of which speed up data read times), is under development. Ultrium tapes are available in 10 GB, 30 GB, 50 GB, and 100 GB native formats. The first generation of IBM Ultrium tape drives, the 3580-H11 and 3580-L11 units, which shipped in September 2000, offered the same basic feeds and speeds as the new ones. However, new models have lower-cost-of-ownership prices because IBM is offering different warranty terms on the H13/L13 tape drives than it did on the older H11/L11 units. The original machines have IBM's standard one-year onsite warranty, which customers know and (presumably) love, while the new Ultrium units have a three-year parts-exchange warranty service, under which customers will help to identify parts that have failed in the unit and then send them back to IBM to be replaced. Customers save money because they don't pay those minimum monthly maintenance fees, which used to be an easy source of revenue for IBM, but now that the machines are so reliable, no one wants to pay those maintenance fees. The H11 and H13 units cost $5,375, and the L11 and L13 units cost $5,175. A three-year onsite warranty (24/7 support) for an H11 or L11 machine costs $2,091, but the three-year exchange maintenance plan for the H13 or L13 machines with support during the business hours of 9 to 5 only costs $900, and a 24/7 support version of this exchange plan costs only $1,200. This lower-cost maintenance plan is meant for customers who aren't concerned with the availability of their tape units, perhaps because they have many of them. The 3581-H13 and L13 units are the same single-deck Ultrium drives, except that they include a seven-tape autoloader that provides a total unattended backup capacity of 700 GB in native mode and 1.4 TB in compressed mode. The 3581-H13 costs $8,060, while the 3581-L13 costs $7,860. The three-year exchange maintenance plan for these machines with 9-to-5 support costs $1,500, while the 24/7 support plan costs $2,000. IBM's Ultrium drives require OS/400 V4R4 or higher on iSeries and AS/400 servers, and run on RS/6000 and pSeries servers with AIX 4.3.2 or higher, on Sun Microsystem's Sparc servers running Solaris 2.6, 2.7, and 8 (not the new Solaris 9), on HP Unix servers running HP-UX 11.0 or higher, and on Wintel servers running Microsoft's Windows NT 4.0 (SP6) and Windows 2000 operating systems.
