"Storage Networks Explained has much to recommend it.... ararity in the literature of digital data storage – a completeexposition of both the base subject matter and its applications,which at the same time offers a level of readability making itsuitable as an introduction to the subject. Storage NetworksExplained is also flexible. It can be read cover-to-cover,browsed, or used as a reference. I recommend Storage NetworksExplained as an essential component of any active informationtechnology library." —Paul Massiglia, Technical Director, VERITASSoftware Corporation Storage networks will become a basic technology likedatabases or local area networks. According to market research, 70%of external storage devices will be connected via storage networksin 2003. The authors have hands-on experience of network storagehardware and software, they teach customers about concrete networkstorage products, they understand the concepts behind storagenetworks, and show customers how storage networks address theirbusiness needs. Storage networks provide shared access to stored data frommultiple computers and servers, thus increasing storageefficiency and availability. They permit informationmanagement functions such as backup and recovery, data mirroring,disaster recovery, and data migration to be performed quickly andefficiently, with a minimum of system overhead. This book explains how to use storage networks to fixmalfunctioning business processes, covering the technologies aswell as applications. A hot topic that will become increasinglyimportant in the coming years. One of the first books to focus on using rather than buildingstorage networks, and how to solve problems. Looking beyond technology and showing the true benefits ofstorage networks. Covers fibre channel SAN, Network Attached Storage, iSCSI andInfiniBand technologies. Contains several case studies (e.g. the example of a travelportal, protecting a critical database) Endorsed by the Storage Networking Industry Association. Written by very experienced professionals who tailored the bookspecifically to meet customer needs including support withsupplementry material on Troppens website and Preface written byTony Clark. Provides basic application information key for systemsadministrators, database administrators and managers who need toknow about the networking aspects of their systems. As well assystems architects, network managers, information managementdirectors and decision makers. This book also supports applications for graduate students andother relevant courses in the field.

What exactly is virtualization? As this concise book explains, virtualization is a smorgasbord of technologies that offer organizations many advantages, whether you're managing extremely large stores of rapidly changing data, scaling out an application, or harnessing huge amounts of computational power. With this guide, you get an overview of the five main types of virtualization technology, along with information on security, management, and modern use cases. Topics include: Access virtualization—Allows access to any application from any device Application virtualization—Enables applications to run on many different operating systems and hardware platforms Processing virtualization—Makes one system seem like many, or many seem like one Network virtualization—Presents an artificial view of the network that differs from the physical reality Storage virtualization—Allows many systems to share the same storage devices, enables concealing the location of storage systems, and more

The superabundance of data that is created by today's businesses is making storage a strategic investment priority for companies of all sizes. As storage takes precedence, the following major initiatives emerge: Flatten and converge your network: IBM® takes an open, standards-based approach to implement the latest advances in the flat, converged data center network designs of today. IBM Storage solutions enable clients to deploy a high-speed, low-latency Unified Fabric Architecture. Optimize and automate virtualization: Advanced virtualization awareness reduces the cost and complexity of deploying physical and virtual data center infrastructure. Simplify management: IBM data center networks are easy to deploy, maintain, scale, and virtualize, delivering the foundation of consolidated operations for dynamic infrastructure management. Storage is no longer an afterthought. Too much is at stake. Companies are searching for more ways to efficiently manage expanding volumes of data, and to make that data accessible throughout the enterprise. This demand is propelling the move of storage into the network. Also, the increasing complexity of managing large numbers of storage devices and vast amounts of data is driving greater business value into software and services. With current estimates of the amount of data to be managed and made available increasing at 60% each year, this outlook is where a storage area network (SAN) enters the arena. SANs are the leading storage infrastructure for the global economy of today. SANs offer simplified storage management, scalability, flexibility, and availability; and improved data access, movement, and backup. Welcome to the cognitive era. The smarter data center with the improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric. A smarter data center that hosts IBM Storage solutions can provide an environment that is smarter, faster, greener, open, and easy to manage. This IBM® Redbooks® publication provides an introduction to SAN and Ethernet networking, and how these networks help to achieve a smarter data center. This book is intended for people who are not very familiar with IT, or who are just starting out in the IT world.

"Virtual storage devices...are simply representations of the behavior of physical devices of the same type. These representations are made to the devices' clients-usually application programs- in the form of responses I/O requests. If these responses are sufficiently like those of the actual devices, clients need not be aware that the devices are not "real". This simple but powerful concept is what makes all of storage virtualization work-no application changes are required to reap benefits. any application or system software that can use disk drives, tape drives, libraries, or file systems can use equivalent virtual devices without being specifically adapted to do so." -Virtual Storage Redefined, Chapter 1. With these words, the authors embark on the journey through the techniques and applications of virtual disk storage that explains the what, why, and how clearly and directly. This book is a must for architects, planners, and administrators who are responsible for enterprise data storage.

Virtualization has become a “megatrend”—and for good reason. Implementing virtualization allows for more efficient utilization of network server capacity, simpler storage administration, reduced energy costs, and better use of corporate capital. In other words: virtualization helps you save money, energy, and space. Not bad, huh? If you’re thinking about “going virtual” but have the feeling everyone else in the world understands exactly what that means while you’re still virtually in the dark, take heart. Virtualization for Dummies gives you a thorough introduction to this hot topic and helps you evaluate if making the switch to a virtual environment is right for you. This fun and friendly guide starts with a detailed overview of exactly what virtualization is and exactly how it works, and then takes you on a tour of the benefits of a virtualized environment, such as added space in overcrowded data centers, lower operations costs through more efficient infrastructure administration, and reduced energy costs through server consolidation. Next, you’ll get step-by-step guidance on how to: Perform a server virtualization cost versus benefit analysis Weigh server virtualization options Choose hardware for your server virtualization project Create a virtualized software environment Migrate to—and manage—your new virtualized environment Whether you’re an IT manager looking to sell the idea to your boss, or just want to learn more about how to create, migrate to, and successfully manage a virtualized environment, Virtualization for Dummies is your go-to guide for virtually everything you need to know.
