Rate this book. The superabundance of data that is created by today's businesses is making storage a strategic investment priority for companies of all sizes.

As storage takes precedence, the following major initiatives emerge: Storage is no longer an afterthought. Too much is at stake. Companies are searching for more ways to efficiently manage expanding volumes of data, and to make that data accessible throughout the enterprise.

This demand is propelling the move of storage into the network. Also, the increasing complexity of managing large numbers of storage devices and vast amounts of data is driving greater business value into software and services.

SANs are the leading storage infrastructure for the global economy of today. SANs offer simplified storage management, scalability, flexibility, and availability; and improved data access, movement, and backup.

The smarter data center with the improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric. A smarter data center that hosts IBM Storage solutions can provide an environment that is smarter, faster, greener, open, and easy to manage. This book is intended for people who are not very familiar with IT, or who are just starting out in the IT world.

In a SAN data is transferred, stored and accessed on a block level. As such a SAN does not provide data file abstraction, only block-level storage and operations. But file systems have been developed to work with SAN software to provide file-level access.

These are known as SAN file systems, or shared disk file system. If multiple systems were simply to attempt to share a LUN, these would interfere with each other and quickly corrupt the data. Any planned sharing of data on different computers within a LUN requires software, such as SAN file systems or clustered computing.

Video editing systems require very high data transfer rates and very low latency. SANs in media and entertainment are often referred to as serverless due to the nature of the configuration which places the video workflow ingest, editing, playout desktop clients directly on the SAN rather than attaching to servers.

Control of data flow is managed by a distributed file system such as StorNext by Quantum. SAN Storage QoS enables the desired storage performance to be calculated and maintained for network customers accessing the device.

QoS can be impacted in a SAN storage system by an unexpected increase in data traffic usage spike from one network user that can cause performance to decrease for other users on the same network. Over-provisioning can be used to provide additional capacity to compensate for peak network traffic loads. However, where network loads are not predictable, over-provisioning can eventually cause all bandwidth to be fully consumed and latency to increase significantly resulting in SAN performance degradation.

Storage virtualization is the process of abstracting logical storage from physical storage. The physical storage resources are aggregated into storage pools, from which the logical storage is created.

It presents to the user a logical space for data storage and transparently handles the process of mapping it to the physical location, a concept called location transparency. This is implemented in modern disk arrays, often using vendor proprietary technology. However, the goal of storage virtualization is to group multiple disk arrays from different vendors, scattered over a network, into a single storage device.
