Abstract
This IBM® Redbooks® publication provides guidance for IBM AIX® administrators and storage architects who design, optimize, and protect mission-critical workloads on IBM Power with IBM Storage FlashSystem (formerly known as IBM FlashSystem®).
The book explains how AIX host configuration, storage virtualization, and modern IBM Storage FlashSystem capabilities work together to support performance, availability, and cyber resilience. It covers key topics such as multipath I/O (MPIO) tuning, AIX Logical Volume Manager (LVM) alignment, queue depth settings, reserve policies, and use of the Host Attachment Kit.
The publication also describes high availability and disaster recovery (HADR) options for AIX environments, including IBM PowerHA® SystemMirror®, IBM PowerVC™, IBM Copy Services Manager (CSM), policy-based replication (PBR), IBM HyperSwap®, three-site topologies, and Safeguarded Copy (SGC).
By aligning AIX host settings with IBM Storage FlashSystem capabilities, administrators can improve I/O performance, simplify operations, and select the appropriate orchestration tool for each HA, DR, and cyber-resiliency requirement.
