The XIV Storage System is a scalable enterprise storage system that is based on a grid array of hardware components. It can attach to both Fibre Channel Protocol (FCP) and IP network Small Computer System Interface (iSCSI) capable hosts. This system is a good fit for clients who want to be able to grow capacity without managing multiple tiers of storage.
The XIV Storage System is suited for mixed or random access workloads, including online transaction processing, video streamings, images, email, and emerging workload areas, such as Web 2.0 and storage cloud.
The focus of this edition is on the XIV Gen3 hardware Release 3.4, running Version 11.4 of the XIV system software. With this version, XIV Storage System offers 4 TB drives, and enhanced caching with optional 800GB flash cache devices (SSDs) per module. The IBM XIV software Version 11.4, XIV Gen3 supports encryption for all capacity points. This version also scales XIV snapshot management out with the new Hyper-Scale Consistency, by coordinating concurrent snapshots of volumes that are spread across multiple XIVsystems and belong to one application.
In the first few chapters of this book, we describe many of the unique and powerful concepts that form the basis of the XIV Storage System logical and physical architecture. We explain how the system is designed to eliminate direct dependencies between the hardware elements and the software that governs the system. In subsequent chapters, we explain the planning and preparation tasks that are required to deploy the system in your environment by using the intuitive, yet powerful XIV Storage Manager GUI or the XIV command-line interface (XCLI).
We describe the performance characteristics of the XIV Storage System and present options that are available for alerting and monitoring, including an enhanced secure remote support capability.
