This IBM® Redbooks® publication captures several of the best practices based on field experience and describes the performance gains that can be achieved by implementing the IBM System Storage® SAN Volume Controller V6.2. This book begins with a look at the latest developments with SAN Volume Controller V6.2 and reviews the changes in the previous versions of the product. It highlights configuration guidelines and best practices for the storage area network (SAN) topology, clustered system, back-end storage, storage pools and managed disks, volumes, remote copy services, and hosts. Then, this book provides performance guidelines for SAN Volume Controller, back-end storage, and applications. It explains how you can optimize disk performance with the IBM System Storage Easy Tier® function. Next, it provides best practices for monitoring, maintaining, and troubleshooting SAN Volume Controller. Finally, this book highlights several scenarios that demonstrate the best practices and performance guidelines. This book is intended for experienced storage, SAN, and SAN Volume Controller administrators and technicians. Before reading this book, you must have advanced knowledge of the SAN Volume Controller and SAN environment. For background information, read the following Redbooks publications: Implementing the IBM System Storage SAN Volume Controller V5.1, SG24-6423 Introduction to Storage Area Networks, SG24-5470

IBM TotalStorage Productivity Center for Replication Version 3, Release 1 brings support for the advanced copy services capabilities on the DS8000 and DS6000, in addition to the support for ESS model 800 and SVC. This support focuses on automating administration and configuration of these services, operational control (starting, suspending, resuming) copy services tasks and monitoring and managing the copy services sessions. In addition to the support for FlashCopy and Metro Mirror, TotalStorage Productivity Center for Replication V3R1 supports Global Mirror on the ESS800, DS8000, and DS6000 hardware platforms. Advanced disaster recovery functions are also supported with failover/failback (planned and unplanned) from a primary site to a disaster recovery site. TotalStorage Productivity Center for Replication also can monitor the performance of the copy services that provide a measurement of the amount of replication and the amount of time that is required to complete the replication operations. This IBM Redbooks publication provides the information you need to install TotalStorage Productivity Center for Replication, and create and manage replication sessions on AIX. Scenarios are provided that document the work performed in our laboratory setting, using the GUI and CLI.

IBM TotalStorage Productivity Center is a suite of infrastructure management software that can centralize, automate, and simplify the management of complex and heterogeneous storage environments. It can help reduce the effort of managing complex storage infrastructures, improve storage capacity utilization, and improve administration efficiency. IBM TotalStorage Productivity Center allows you to respond to on demand storage needs and brings together, in a single point, the management of storage devices, fabric, and data. This IBM Redbooks publication is intended for administrators and users who are installing and using IBM TotalStorage Productivity Center. It provides an overview of the product components and functions. We describe the hardware and software environment required, provide a step-by-step installation procedure, and offer customization and usage hints and tips. This book is not a replacement for the existing IBM Redbooks, or product manuals, that detail the implementation and configuration of the individual products that make up the IBM TotalStorage Productivity Center , or the products as they may have been called in previous versions. We refer to those books as appropriate throughout this book.

Now that you have installed your SAN, how are you going to manage it? This IBM Redbooks publication describes the new product, IBM Tivoli Storage Area Network Manager, an active, intelligent, business-centric management solution for storage resources across the enterprise. IBM Tivoli Storage Area Network Manager provides effective discovery and presentation of SAN physical and logical topologies and provides multiple views of the SAN, including zones. Through its interface, it can be configured to show historical and real-time monitoring of SAN fabric devices. With IBM Tivoli Storage Area Network Manager, you will know what's on your SAN, how the devices are connected, and how storage is assigned to the hosts. If something goes wrong, or new devices are added, the topology display automatically updates to show the changed topology. SAN generated events can be displayed on the manager system, or forwarded to another SNMP manager or Tivoli Enterprise Console. This book is written for those who want to learn more about IBM Tivoli SAN Manager, as well as those who are about to implement it. This second edition of the book is current to IBM Tivoli SAN Manager V1.2. Please note that the additional material referenced in the text is not available from IBM.

Storage growth continues to accelerate, and the cost of disk can approach 80% of total system hardware costs. Yet, the storage in most businesses is typically only about 50% used. How can you take control of your storage assets to render utilization more efficient, and make the most of your storage dollars? The second edition of this book is updated for IBM Tivoli Storage Resource Manager Version 1.2 Please note that the additional material referenced in the text is not available from IBM.
