Preparing to configure shared memory

Before you configure the shared memory pool and create logical partitions that use shared memory (hereafter referred to as shared memory partitions), you need to plan for the shared memory pool, the shared memory partitions, the paging space devices, and the Virtual I/O Server logical partitions (hereafter referred to as paging VIOS partitions).

    Before you configure the shared memory pool and create logical partitions that use shared memory (hereafter referred to as shared memory partitions), you need to determine the size of the shared memory pool, the number of shared memory partitions to assign to the shared memory pool, and the amount of memory to assign to each shared memory partition.

    Before you configure the shared memory pool and create logical partitions that use shared memory (hereafter referred to as shared memory partitions), you need to determine the size of the shared memory pool, the amount of memory to assign to each shared memory partition, the number of paging space devices to assign to the shared memory pool, and the redundancy configuration of the Virtual I/O Server logical partitions that you assign to the shared memory pool.
