Network Attached Storage

Did you know that as much as 500f your storage capacity may be wasted or underutilized? Efficient management of stored data is becoming a necessity for every enterprise. The high cost of downtime creates a need for the increased reliability provided by distributed storage systems. Thus the use of storage networks to manage access to data not only provides an increase in performance and survivability, but also generates real and immediate cost savings. This book focuses on three primary areas: architectures for distributed storage networks, storage protocols and their inherent distance limitations, and management techniques for distributed storage networks. "Distributed Storage Networksdescribes the evolution of data processing from a computer-centric to a storage-centric modelintroduces the concept of a distributed storage-centric processing modelexplains common storage network functional components, such as fabric switches, storage directors, file managers, and gateways, and their roles in a distributed storage environmentdiscusses distributed storage network applications, including storage integration, remote database synchronization, and backup/recovery functionsprovides a comparative view of Storage Area Network (SAN) and Network Attached Storage (NAS) functions and capabilities, and points out the advantages of each One of the primary obstacles to implementing a storage network cited by enterprise IT managers is a lack of knowledge about storage networking technology and the specific issues involved in extending a SAN or NAS over the MAN or WAN. The primary goal of this book is to provide IT managers, planners, and telecommunications professionals with the information theyneed in order to choose the technologies best suited for their particular environment.

""Dilip Naik's Inside Windows Storage is an invaluable reference for developers and customers alike and is a must-read for anyone wishing to implement Windows-based storage networking." --Tom Clark, Director, Technical Marketing, Nishan Systems The Windows and enterprise storage markets are converging. Migrating upwards from low-end servers, Windows is becoming a genuine platform for running mission-critical applications. The enterprise storage market is moving from high-end servers to also include medium range servers. Thanks to a slew of enterprise storage related features, Microsoft Windows storage technologies are rapidly gaining widespread acceptance. System administrators, programmers, and technical managers need to learn to appreciate and to tap the full potential of Windows enterprise storage. "Inside Windows Storage is the first book to provide a comprehensive look at new and emerging Microsoft storage technologies. The text begins with an overview of the enterprise storage industry and Windows Server architecture, including the Windows NT I/O subsystem. With that foundation in place, readers explore the ins and outs of current Windows offerings, upcoming Windows server releases, and third-party products. Key topic coverage includes: Direct Attached Storage, including the new Windows Storport driver modelFibre Channel Storage Area Networks (SANs)Network Attached Storage (NAS), including the Windows NT network stack and an overview of CIFSBackup and restore technologies, including Windows XP and Windows Server 2003 Volume Shadow Copy ServiceFile systems and disk virtualization, including a detailed overview of NTFS as well as a study of Windows cluster filesystemsStorage management, including the new Windows Virtual Disk ServiceIP Storage and InfinibandHigh availability, including RAID mirroring as well as multi path I/O solutions This extensive guide concludes by tracing Windows NT storage features as they appear in Windows NT 4.

Network attached processing - Network attached processing is the industry’s first solution specifically targeting virtual machine based applications and the transaction processing needs of the modern application tier. Network attached processing provides massive amounts of compute power as a shared network service, similar to the manner in which network attached storage provides shared storage capacity to the data center.

Direct Attached Storage - Direct Attached Storage (DAS) refers to a storage system directly attached to a server or workstation, without a storage network in between.

Storage area network - In computing, a storage area network (SAN) is a network designed to attach computer storage devices such as disk array controllers and tape libraries to servers. As of 2005, SANs are common in enterprise storage.

Storage Area Network A Storage Area Network (SAN) in computing is a network which is designed to attach computer storage devices such as Disk Array Controllers and Tape Silos to servers. The SAN allows the hard disks are 'pooled' in this case the switches would be Fibre Channel fabric protocol and in this way, the utilisation of the members of the members of the storage capacity is usually made using optical fiber links. nas-san comparison - including NAS and SAN whitepapers. Many systems were pushed to the Ethernet network traffic. NAS devices also suffer from the delays introduced by the operating systems' network stacks. A SAN is made up of a number of fabric switches which are connected together to form the network. iSCSI - attempt to re-unify storage and communication networks. As of 2003, SANs are increasingly considered the best way of storing large volumes of data. This problem began to be shared amongst the servers.
