This is the first comprehensive book to cover Novell's hot new clustering and storage area network solutions -- a security, collaboration and 100% high-availability must for any business. The book is a modular, comprehensive look at the design of SAN's and clusters. Also included are solutions supported by NCS, NCS and SAN features, functions, implementation and troubleshooting and configuration within the SAN and cluster. The authors have taken a unique, modular approach in the book so in cases where perhaps SAN's are being implemented in a mixed NetWare and Microsoft Windows 2000 operating system environment to share an Oracle database.
