Efficient, distributed data placement strategies for storage area networks (extended abstract)
André Brinkmann, Kay Salzwedel, Christian Scheideler · 2000
In the last couple of years a dramatic growth of enterprise data storage capacity can be observed. As a result, new strategies have been sought that allow servers and storage being centralized to better manage the explosion of data and the overall cost of ownership. Nowadays, a common approach is to combine storage devices into a dedicated network that is connected to LANs and/or servers. Such networks are usually called storage area networks (SAN). A very important aspect for these networks is scalability. If a SAN undergoes changes (for instance, due to insertions or removals of disks), it may be necessary to replace data in order to allow an efficient use of the system. To keep the influence of data replacements on the performance of the SAN small, this should be done as efficiently as possible.
