  • Data storage management

    Successful data storage management uses a comprehensive suite of tools to configure, provision, archive and report storage activities, according to a well-defined set of management policies or processes. The tools and the processes must work together -- the best tools are useless if they're applied inconsistently, and the most refined policies cannot be implemented without capable tools. This chapter will get you started learning about data storage management.

  • Storage area network

    Traditional network storage was located inside, or directly connected to, individual file servers that were often scattered across workgroups throughout an organization. A storage area network (SAN) overcomes the problems associated with traditional systems by moving storage resources off of the common user network and reorganizing those storage components into an independent, high-performance network. This guide will help you get started learning about SANs.

  • Network attached storage-Data Storage Basics

    Network attached storage (NAS) offers accessibility and performance that falls between server storage and SAN storage. NAS devices attach to the LAN through an ordinary Ethernet connection and IP address, providing disk storage as an independent network device. This chapter will get you started learning about NAS, covering such topics as NAS backup, hardware and architecture, protocols and more.
