  • Secure Data Storage – White Paper Storage Technologies 2008
    1 Secure Data Storage – White Paper Storage Technologies 2008 Secure Data Storage - An overview of storage technology - Long time archiving from extensive data supplies requires more then only big storage capacity to be economical. Different requirements need different solutions! A technology comparison repays. Author: Dr. Klaus Engelhardt Dr. K. Engelhardt 2 Secure Data Storage – White Paper Storage Technologies 2008 Secure Data Storage - An overview of storage technology - Author: Dr. Klaus Engelhardt Audit-compliant storage of large amounts of data is a key task in the modern business world. It is a mistake to see this task merely as a matter of storage technology. Instead, companies must take account of essential strategic and economic parameters as well as legal regulations. Often one single technology alone is not sufficient to cover all needs. Thus storage management is seldom a question of one solution verses another, but a combination of solutions to achieve the best possible result. This can frequently be seen in the overly narrow emphasis in many projects on hard disk-based solutions, an approach that is heavily promoted in advertising, and one that imprudently neglects the considerable application benefits of optical storage media (as well as those of tape-based solutions). This overly simplistic perspective has caused many professional users, particularly in the field of long-term archiving, to encounter unnecessary technical difficulties and economic consequences. Even a simple energy efficiency analysis would provide many users with helpful insights. Within the ongoing energy debate there is a simple truth: it is one thing to talk about ‘green IT’, but finding and implementing a solution is a completely different matter.

Snyder • j' 1964 r .-I ,_ Department of Defense Washington, D. c. 20301 -FOR OFFICIAL USE ONLY DocI. ID: 6586784 r PREFACE The author has attempted to write this material so that it will be easily understood by those who have had only limited experience with computers. To aid those readers, several terms and concepts have been defined, and Chapter 1 includes a brief discussion of principles of computer operation, programming, data-preparation prob­ lems, and automatic programming.

To some small extent, the comments on operational utility bring out the very real usefulness of computers for the solution of data-processing problems. T--·-----i !
