ATA企业的存储应用分析(pdf 11页)(英文)

The intent of this paper is to educate the reader about information that will
allow you to intelligently determine where Serial ATA fits in your environment and where it does not, and in fact where it should be avoided. It will be shown that Serial ATA solutions will not be better in performance than FC drives, but in many cases good enough to justify the lower dollar costs.
As we all know, the IT industry has been under an extreme budget squeeze for the
last 30 months. CIOs no longer have a blank check to spend on upgrading or implementing new systems. The trend to do more with less, applies not only to staff augmentation, but to hardware acquisition as well. Often it is a desirable tradeoff to obtain a lower cost solution, which may not feature the highest performance, but is perfectly sufficient for the application at hand.
Within this context, companies today face storage capacity requirements that are
increasing at a tremendous pace. Enterprises are generating massive amounts of data—e-mail, e-mail attachments, video, audio and databases—and IT managers are anxious to identify and purchase the most cost effective, easy-to-manage storage solutions available.
Information, now more than ever, is also seen as a vital corporate asset with intrinsic
value. Federal requirements for information storage and access mandated by The Health Insurance Portability and Accountability Act (HIPPA) and the Sarbanes-Oxley Act, as well as other legislation are accelerating companies into regulatory compliance to protect some of their most valuable and potentially dangerous information from improper use.
