IBM FlashSystem A9000, IBM FlashSystem A9000R, and IBM XIV Storage System: Host Attachment and Interoperability

Book Description

This IBM® Redbooks® publication provides information for attaching the IBM FlashSystem® A9000, IBM FlashSystem A9000R, and IBM XIV® Storage System to various host operating system platforms, such as IBM AIX® and Microsoft Windows.

This publication was last updated in May 2019 to cover the VLAN tagging and port trunking support available with software version 12.3.2 (see in particular section 2.4, "VLAN tagging" on page 67.

The goal is to give an overview of the versatility and compatibility of the IBM Spectrum™ Accelerate family of storage systems with various platforms and environments.

The information that is presented here is not meant as a replacement or substitute for the IBM Storage Host Attachment Kit publications or other product publications. It is meant as a complement and to provide usage guidance and practical illustrations.

This publication does not address attachments to a secondary system used for Remote Mirroring or data migration. These topics are covered in IBM FlashSystem A9000 and IBM FlashSystem A9000 and A9000R Business Continuity Solutions, REDP-5401.
