The Tape Renaissance
The Tape Renaissance By: Fred Moore President, Horison Information Strategies www.horison.com The magnetic tape data storage industry has withstood numerous challenges from its own past performance, from the HDD industry, and mainly from those who are simply uninformed about the major transformation the tape industry has delivered. Early experience with numerous non-mainframe tape technologies were troublesome and turned many data centers away from using tape in favor of HDDs. Mainframe tape technology was more robust. Many data centers still perceive tape as mired in the world of legacy tape as a result. However, this view is completely out of date. The Legacy Tape Era The tape problems of the past were numerous and resulted in time-consuming reliability and management issues. Edge, stretch, tear, cartridge load problems and crimping were common. The servo tracks were written on the edge of the tape media and dropping a cartridge often meant damage to the servo leaving a non-readable tape. Metal particle (non-oxidized) media life was typically 4-10 years before concerns about re-readability arose. As the issues persisted, the HDD industry took advantage of these concerns and actively pronounced “tape is dead”. The Tape Renaissance Changes the Game The advent of LTO (Linear Tape Open) from the LTO consortium marked the beginning of the tape renaissance. LTO was originally developed in the late 1990s as an open standard alternative to the numerous proprietary magnetic tape formats that were available at the time. Today, Hewlett Packard Enterprise, IBM, and Quantum comprise the LTO Consortium, which directs development and manages licensing and certification of media and mechanism manufacturers. -

The DLT Tape Drive Maintains Internal Information About the Tape on a Tape Directory Track
Question 1: Why does my DLT tape drive pause when cataloging some tapes? Answer: The DLT tape drive maintains internal information about the tape on a tape directory track. The directory track is updated before the tape is ejected from the drive. If the drive is powered off without ejecting the tape first, this information is lost. Re-generating the tape directory information takes several hours to complete, which makes it seem like the drive is hung. Allow sufficient time for the operation to complete and then eject the tape. Normal operation will resume after the directory track has been updated. Question 2: A backup to my DLT tape drive is stuck at 99% complete. What should I do? Answer: The backup most likely fails to complete because the Eject media after job completes option is selected on tape drives that require you to manually remove the tape (such as Digital Linear Tape (DLT), Linear Tape-Open (LTO), Travan, and On-stream drives). To remedy this situation, either deselects the Eject media... option or using BEUTILITY, you can configure Backup Exec to set automatic responses to the media alert. Question 3: After I recovered my cluster and all shared disks, the cluster services will not start. Why won’t it start and how can I get it started? Answer: The cluster service may not start because the disk signature on the Quorum disk is different from the original signature. If you have the Microsoft 2000 Resource Kit use Dumpcfg.exe or Cluster recovery from the Microsoft 2003 Resource Kit to replace the disk. -

Magneto-Optical Drives, Flash Memory Devices, and Tape Drives Are Useful Supplements to Primary Storage
13 0789729741 ch12 7/15/03 4:11 PM Page 663 CHAPTER 12 High-Capacity Removable Storage 13 0789729741 ch12 7/15/03 4:11 PM Page 664 664 Chapter 12 High-Capacity Removable Storage The Role of Removable-Media Drives Since the mid-1980s, the primary storage device used by computers has been the hard disk drive. However, for data backup, data transport between computers, and temporary storage, secondary storage devices such as high-capacity removable media drives, floptical drives, magneto-optical drives, flash memory devices, and tape drives are useful supplements to primary storage. Pure optical storage—such as CD-R, CD-RW, DVD-RAM, DVD+RW, DVD-RW, and others—is covered in Chapter 13, “Optical Storage.” These types of drives can also be used as a supplement to hard disk storage as well as for pri- mary storage. The options for purchasing removable devices vary. Some removable-media drives use media as small as a quarter or your index finger, whereas others use larger media up to 5 1/4''. Most popular removable- storage drives today have capacities that range from as little as 16MB to as much as 100GB or more. These drives offer fairly speedy performance and the capability to store anything from a few data files or less frequently used programs to complete hard disk images on a removable disk or tape. The next two sections examine the primary roles of these devices. Extra Storage As operating systems and applications continue to grow in size and features, more and more storage space is needed for these programs as well as for the data they create. -
