Abstract

With most tightly coupled processor systems, the hardware may be split into multiple independent operating partitions (for hardware subsystems and/or concurrent maintenance). Typically, the hardware elements (I/O, CPU, storage) that comprise each partition are fixed in number and identification by implementation and packaging of the hardware.

Operator Complexities In Forming Variable Size Operating Partitions

With most tightly coupled processor systems, the hardware may be split into multiple independent operating partitions (for hardware subsystems and/or concurrent maintenance). Typically, the hardware elements (I/O, CPU, storage) that comprise each partition are fixed in number and identification by implementation and packaging of the hardware.

In tightly coupled processor systems containing large numbers of hardware elements, fixed partition definitions are undesirable. The problem is that fixed partitions infrequently meet the exact needs of the user. Too many elements are wasteful and too few are not enough. To address this problem, systems with many elements provide the capability bility to define variable partitions (i.e., partitions with variable numbers of I/O, storage, and processor elements). This permits the user to establish partitions which are tailored to meet the needs of the workload.

To define a variable partition, the operator faces the problem of dealing with specific hardware elements rather than fixed groups of elements. The operator must know which elements are currently in his partition, and which elements are available but offline. It should be noted that offline available elements must be distinguished from offline inoperative or in use elements (i.e., in use by another partition).

An enhancement to reduce operator complexity when defining variable partitions is described below. PARTITION ONLINE (OFFLINE) SCENARIO
