Summary and conclusions IBM's System Storage DS series is a stable high-end storage system that is well positioned to cover current and future user requirements. How it works The October announcement complements the existing pro. The SE FlashCopy is licensed, chargeable storgae. Initiallythe DS used the Sequential Prefetching in Adaptive Replacement Cache SARC algorithm, which is a self-tuning, self-optimizing cache management managed for a wide range of sequential or random workloads.
Global Mirror interfaces IBM's System Storage DS October release enhances performance, functionality, and provides the ability to reduce costs, and simplify storage management. The general availability of most of the enhancements is the 7th December System Storage Productivity Center is designed to provide an integrated view for simplified management of all IBM-installed storage devices.

The new feature Dynamic Volume Expansion, as its name suggests, is designed to provide the ability to increase the space on a volume non-disruptively. Geographically Dispersed Parallel Sysplex overview The DS series internal design, based on commercial server technology, has some significant design advantages, allows easy deployment of future enhancements in performance or functionality and also may enable IBM to be competitive with its rs8000.
This book provides the details managre to implement and ds0800 each of the Copy Services functions. XRC was one of first remote copy techniques introduced more than a decade ago. Metro Mirror implementation considerations Global Copy examples Ranks reserved for FlashCopy Chapter Announcement impact The winners are end-users which will gain from the functionality, performance and potential TCO improvements.
AMP optimizes cache efficiency by incorporating an autonomic, workload-responsive, self-optimizing pre-fetching technology which delivers up to a two-fold increase in the sequential managet capacity of RAID-5 arrays, including for smaller-than-maximum configurations. With this technique, data modifications are temporarily stored in a side-file of the cache and retrieved periodically by the host based System Data Mover SDM.
