"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.
The Holy 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.
