  Storage area network - Wikipedia, the free encyclopedia
Storage networks are distinguished from other forms of network storage by the low-level access method that they use.
Most storage networks use the SCSI protocol for communication between servers and devices, though they do not use its low-level physical interface..
Sharing storage usually simplifies storage administration and adds flexibility since cables and storage devices do not have to be physically moved to move storage from one server to another.

 InfoStor - Part I: Building storage networks: A book excerpt
Storage networks demand a high degree of precision from all components to implement a reliable and predictable environment.
Storage networking requires new methods for starting, establishing, and managing communications, which are considerably different than those used in bus technologies such as parallel SCSI or ATA.
Storage devices and subsystems on storage networks have to be able to screen all of them and accept or reject them with 100% accuracy.

Upgrading your storage network should be a lot easier than it was to implement it in the first place.
The process is called storage resource management, or SRM, and it might help you defer the expense of adding new SAN hardware or networking gear by maximizing the potential of what you've already got.
Most industry watchers expect storage needs to grow by 25% or so this year, which is healthy but a far cry from the annual doubling of storage that most firms had been seeing in the past several years.

 Internet Protocol storage area networks
The fundamental premise of a storage area network is the ability of host servers to share storage resources in the network, enabling a higher degree of utilization than that achieved in the host-server-attached storage model.
Traditional management of storage devices involves tasks such as configuring the RAID (redundant array of independent disks) levels and stripe size for the data to be stored, adding and managing storage capacity, configuring backup, managing restoring and mirroring schedules, monitoring the status and performance of storage devices, handling device errors and configuring storage volume parameters.
The framework should be able to properly authenticate and authorize the different components of the storage area network (storage servers, storage clients, and communication endpoints) and grant access to data based on the security requirements of the data storage subsystem and the entities authorized to access it.

 Reap the benefits of storage networks   (Site not responding. Last check: 2007-10-11)
The goal behind storage virtualization is to isolate the server OS and its applications from the technicalities of storage devices, thereby simplifying media management and the allocation of storage space to each server, or host, computer.
From a broader perspective, storage virtualization could be the "killer application" of networked storage, and become one of the crucial factors driving a company's choice of storage vendor.
Storage virtualization is likely to play a similar role in the adoption of networked storage, by offsetting high hardware acquisition costs with otherwise unattainable functionality and administrative efficiency.

 Storage Area Network or Networks (SAN) - Important to your business!
Typically, finding storage area network (SAN) interoperability information usually requires countless hours of searching and contacting vendors who want to sell you their product with no regard to your current network setup or networked storage needs.
There are many great reasons for enterprises to move to a storage network from DAS (a local disk solution): dramatically simplified storage management, much more efficient utilization of storage capacity, high availability, scalability — all benefits impossible to achieve in a DAS environments.
We believe that storage area networks (SAN) are the wave of the future, and we talk with certified vendors all over the United States about their interoperability needs and concerns.

In very basic terms, a SAN can be anything from two servers on a network accessing a central pool of storage devices to several thousand servers accessing many millions of megabytes of storage.

Issues stemming from storage systems running across local-area networks or wide-area networks make security "a fragile proposition," says report co-author Jamie Gruener.
Data-storage management and storage-network management involve protecting data both "at rest" and "in flight" -- that is, stationary on particular media or traveling over network conduits -- as it is routed by management systems to various devices.
