This IBM Redbook describes how to install and configure the very latest IBM storage solution and concept, the IBM TotalStorage Network Attached Storage 300G, in heterogeneous environments. The 300G series is an innovative Network Attached Storage (NAS) appliance that connects clients and servers on an IP network to Fibre Channel storage, efficiently bridging the gap between LAN storage needs and SAN storage capacities. The NAS 300G is a storage solution for Linux/UNIX and Windows NT/2000 environments. In this book, we show you how to integrate the NAS 300G and explain how it can benefit your company's business needs. This book is an easy-to-follow guide which describes the market segment that the 300G is aimed at, and explains NAS installation, ease-of-use, remote management, expansion capabilities, high availability (clustering), and backup and recovery techniques. It also explains cross platform storage concepts and methodologies for common data sharing for Linux/UNIX and Windows NT/2000 environments.

Providing shared access to files is an important aspect of today's computing environment, as it allows easier control and consolidation of data and other assets and enhances information flow through an organization. Traditionally filesharing has been done over the traditional TCP/IP LAN. Storage Area Networks (or SANs) provide the ability for storage to be accessed and moved across a separate dedicated high-speed network. Tivoli SANergy transparently brings these two concepts together, providing all the benefits of LAN-based filesharing at the speed of the SAN. This IBM Redbook provides an introduction to Tivoli SANergy in various environments, including various flavors of UNIX, Microsoft Windows NT, and Windows 2000. It covers installation and setup of the product, with advice and guidance on tuning and performance. It also describes integrating SANergy with other products, including Tivoli Storage Manager and Microsoft Cluster Services. This book is written for IBM, Tivoli, customer, vendor, and consulting personnel who wish to gain an understanding of the Tivoli SANergy product and how best to use it in their environments. We assume a basic understanding of filesharing concepts in various operating system environments, as well as SAN concepts and implementation.

Tivoli Storage Manager, the backbone product of the Tivoli Storage Management product set, is an enterprise-wide network storage management solution. Tivoli Storage Manager Version 4.1 was introduced in July 2000 and is the successor of Tivoli ADSM Version 3.1 and Tivoli Storage Manager Version 3.7. It provides many new functions such as support for mobile systems backup, LAN-free backup and restore of data using a Storage Area Network (SAN) environment, and Windows 2000 exploitation and support. This IBM Redbook presents an overview of Tivoli Storage Manager Version 3.7.3 and Version 4.1. The book provides updates on the Tivoli Storage Management product set, and it gives a detailed description of each of the new functions of Tivoli Storage Manager. The book also discusses in detail Tivoli Storage Manager Windows 2000 exploitation and support, and introduces two other members of the Tivoli Storage Management product set: Tivoli SANergy File Sharing, and Tivoli Decision Support for Storage Management Analysis. This book is intended for customers, consultants, IBM Business Partners, IBM employees, and Tivoli staff who are familiar with ADSM Version 3.1 and Tivoli Storage Manager Version 3.7, and who need to understand what is new in Tivoli Storage Manager Version 3.7.3 and 4.1.

As we now appear to have safely navigated the sea that was the transition from one century to the next, the focus today is not on preventing or avoiding a potential disaster, but exploiting current technology. There is a storm on the storage horizon. Some may call it a SAN-storm that is approaching. Storage Area Networks have lit up the storage world like nothing before it. SANs offer the ability to move data at astonishingly high speeds in a dedicated information management network. It is this dedicated network that provides the promise to alleviate the burden placed on the corporate network in this e-world. Traditional networks, like LANs and WANs, which have long been the workhorses of information movement are becoming tired with the amount of load that is placed upon them, and usually slow down just when you want them to go faster. SANs offer the thoroughbred solution. More importantly, an IBM SAN solution offers the pedigree and bloodlines which have been proven in the most competitive of arenas. Whichever way you look at the SAN-scape, IBM has a solution, product, architecture, or service, that will provide a comprehensive, enterprise-wide, SAN-itized environment. This redbook is written for those professionals tasked with designing a SAN to provide solutions to business problems that exist today. We propose and detail a number of solutions that are available today, rather than speculating on what tomorrow may bring. In this IBM Redbook we have two objectives. The first is to show why a SAN is a much-s
