Abstract
The objective of this IBM Redbook is to provide information on the best configurations for distance solutions in a SAN environment. We show the particular business problems that distance solutions solve now; and with the future in mind, how these solutions can be expanded as the SAN world evolves.
We demonstrate the advantages that the IBM SAN and its OEM partners' and resellers' solutions bring to the marketplace. In addition, we provide information on the key factors to consider when choosing one particular solution over another, in order to protect and maximize your return on investment.
The distributed environment, particularly SAN, has resulted in a significant increase in communications. Data storage requirements have exploded. With these two developments in mind, it is vital to know how, where, and when data should be sent over distances quickly, and how to design and configure new and legacy systems while shaping them for the future.
