Improving Storage Expansion for Servers and Applications
What administrators really need is more capability than is offered by many storage area network (SAN) vendors. Vendors may say that customers can add storage and place it into production online, but only mean that disks can be added to a cabinet — rather than put into expanded and balanced application use — online. Unless customers ask probing questions, this distinction may not be apparent. With Dell EqualLogic™ PS Series arrays, expansion provides additional components without adding management tasks. Each unit not only provides disks, but also controllers, cache and network links to avoid bottlenecks.
