Description
At least 75% of IT hardware expenditures in the next five years will be for data storage. This book shows IT executives how to create a comprehensive strategy for maximizing the availability, performance, and cost-effectiveness of enterprise storage.KEY TOPICS:A revolution in data storage is coming, as IT organizations realize that they must apply the same architectural, scalability, and investment protection criteria to storage purchases as they already apply to servers and other hardware. New categories of products are coming as well: network-attached storage, IBM's storage array architecture, JBOD ("just a bunch of disks") configurations, storage appliances, near-line storage, SANs (storage area networks); and more. Learn how to move towards the "holy grail" of data storage management. Toigo shows how define an enterprise storage framework that maps directly to a specific business and its technical needs, and helps make sense of any new storage alternative.MARKET:For all IT decision-makers responsible for enterprise storage, planning, architecture, and/or distributed systems.
