Management Secondary Storage

Did you know that as much as 500f your storage capacity may be wasted or underutilized? Efficient management of stored data is becoming a necessity for every enterprise. The high cost of downtime creates a need for the increased reliability provided by distributed storage systems. Thus the use of storage networks to manage access to data not only provides an increase in performance and survivability, but also generates real and immediate cost savings. This book focuses on three primary areas: architectures for distributed storage networks, storage protocols and their inherent distance limitations, and management techniques for distributed storage networks. "Distributed Storage Networksdescribes the evolution of data processing from a computer-centric to a storage-centric modelintroduces the concept of a distributed storage-centric processing modelexplains common storage network functional components, such as fabric switches, storage directors, file managers, and gateways, and their roles in a distributed storage environmentdiscusses distributed storage network applications, including storage integration, remote database synchronization, and backup/recovery functionsprovides a comparative view of Storage Area Network (SAN) and Network Attached Storage (NAS) functions and capabilities, and points out the advantages of each One of the primary obstacles to implementing a storage network cited by enterprise IT managers is a lack of knowledge about storage networking technology and the specific issues involved in extending a SAN or NAS over the MAN or WAN. The primary goal of this book is to provide IT managers, planners, and telecommunications professionals with the information theyneed in order to choose the technologies best suited for their particular environment.

"This is a great book at the right time . . . I found the book to be exactly what I was looking for and very well written." --Dr. David Spuler, Director of Advanced Research, BMC Software and Author, Enterprise Application Management with PATROL (1999) What Every Enterprise Needs to Know to Solve Its Data Deluge! Depending on the analyst one follows, corporate IT departments will spend between 75 and 90 cents of every dollar over the next five years on data storage products. The reason is simple: Companies are generating data at a phenomenal rate and increasing their requirements for data storage by 100 percent or more per year. In The Holy Grail of Data Storage Management, Jon William Toigo documents current trends in storage technology and shows IT executives exactly how to plan a comprehensive strategy for maximizing the availability, performance, and cost-effectiveness of enterprise storage. Discover how to: Map your storage strategy to long-term business goals and application data movement requirements Apply architectural, scalability, and investment protection criteria to every storage purchase Customize storage to key enterprise applications, including data warehousing, ERP, OLTP, and e-commerce Master the new skills needed to manage next-generation storage This vendor-neutral guide offers new insight into every next-generation storage technology: network attached storage (NAS), RAID array configurations, storage appliances, near on-line storage, Storage Area Networks (SANs), optical systems, and much more. If you're responsible for enterprise storage, planning, architecture, and/or distributed systems, you'll find this book absolutely indispensable. TheHoly Grail of Data Storage Management is complemented by a new website, http: //www.stormgt.org, which provides useful, up-to-the-minute information on the fast-changing world of storage and storage management technology. See the Introduction for more details.

Hierarchical Storage Management - Hierarchical Storage Management (HSM) is a data storage system that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as hard disk drives, are more expensive (per byte stored) than slower devices, such as optical discs and magnetic tape drives.

Hierarchical storage management - Hierarchical storage management, commonly known as HSM is a widely used technique in computer systems to reduce the cost of bulk data storage, improve performance, or both. The method relies on the tradeoff between high-capacity, low-cost, but slow storage such as magnetic tape media, and the relatively low capacity, expensive, but much faster hard disk storage found in most computers.

Secondary storage - Secondary storage, or external memory, is computer memory that is not directly accessible to the central processing unit of a computer, requiring the use of computer's input/output channels. Secondary storage is used to store data that is not in active use.

Logical volume management - In computer storage, logical volume management or LVM is a method of allocating space on mass storage devices that is more flexible than conventional partitioning schemes. In particular, a volume manager can concatenate, stripe together or otherwise combine partitions into larger virtual ones that can be resized or moved, possibly while it is being used.

Data Secondary Storage - Data Secondary Storage Secondary storage - Secondary storage, or external memory, is computer memory that is not directly accessible to the central processing unit of a computer, requiring the use of computer's input/output channels. Secondary storage is used to store data that is not in active use. Data storage device - In computing, a data storage device—as the name implies—is a device for storing data. It usually refers to permanent (non-volatile) storage, that is, the data will remain ...
