Five unique features of ibm I single-level storesingle-level store

IBM I customers need not be aware of any of the storage technologies that underlie the huge address space because the IBM I manages them automatically. as far as MERS MERs are concerned, all programs and data simply reside in this massive space. users don't have to worry about where a program resides; they need only reference it by name.

Similarly, customers don't have to worry about extending files that are full. the IBM I handles this automatically, too. and when customers add storage devices to the machine, they don't have to redistribute data into SS them; the system recognizes the new available storage and uses it. just try to do that with a Unix or Windows system. most IBM I installations don't even have a traditional database administrator because they don't need one. the system does much of this type of work on its own.

Processing business applications in a multi-application, multi-user environment involves frequent switching between different tasks. because of its single-level store, the IBM I accomplishes this function much more efficiently than conventional systems. switching to a new task in the IBM I is as simple as inserting a branch instruction to the location where the new task resides. there's no need (as in UNIX and Windows systems) to re-create a separate address space before a new task can be executed. because the IBM I is designed for the frequent task switching that characterizes business environments, the system's single-level store not only simplifies storage management but also delivers predictional performance.
