    Microsoft® Windows Storage Server 2003 White Paper Overview of Windows Storage Server 2003 What is Windows Storage Server 2003? Microsoft® Windows® Storage Server 2003 is a network attached storage (NAS) operating system that enables original equipment manufacturers to build appliances that provide dedicated file serving capabilities and storage on the network.
  • Page 20 Microsoft® Windows Storage Server 2003 White Paper • Enhanced Data Protection. Through built-in point-in-time shadow technology, Windows Storage Server 2003 helps businesses keep their data online 24x7 year-round. Using the infrastructure provided by Windows Server 2003 Volume Shadow Copy Service (VSS), the system administrator can use point-in-time shadow copy technologies to make up to 512 snapshots per volume using NTBACKUP (of which 64 are reserved for Shadow Copies for Shared Folders).

  • Page 21: The Basics: How Nas Works

    Microsoft® Windows Storage Server 2003 White Paper The Basics: How NAS Works This section provides a brief introduction to how the NAS server works, and is included to help provide the context for many of the NAS features available with Windows Storage Server 2003. Like all NAS servers, Windows Storage Server 2003 functionally and architecturally consists of three components: the filing system, the wiring (and related hardware), and the storage (disk ).

  • Page 22: Optimizing Nas

    Microsoft® Windows Storage Server 2003 White Paper Optimizing NAS Vendors can configure NAS hardware (and firmware ) such that it is optimized for network file I/O processing and storage. These components include the NAS processor, memory and caching, and the storage devices. There are many different ways to optimize file serving, and the particular approaches taken are vendor specific.

    Microsoft® Windows Storage Server 2003 White Paper New Features in Windows Storage Server 2003 The following are new features in Windows Storage Server 2003. • Volume Shadow Copy Service • Virtual Disk Service • MPIO • Volume Shadow Copy Service (VSS) The Volume Shadow Copy Service (VSS) is an infrastructure that makes possible enhanced data protection though high fidelity backups, rapid data restores, and data transport.

  • Page 32: Virtual Disk Service (Vds)

    Microsoft® Windows Storage Server 2003 White Paper Shadow Copy Transport All of the functionality discussed above is provided with the in-box shadow copy technology on the operating system. The exception to this is shadow copy transport among systems—whether for backup, data mining, testing or fast restores—which requires a hardware provider on the SAN. In a direct attached storage configuration, this data transport between servers is physical.

  • Page 33: Multipath I/O (Mpio)

    Microsoft® Windows Storage Server 2003 White Paper Although many vendors provide NAS appliances preconfigured with RAID, system administrators might want to use VDS to customize the storage solution to meet specific data storage needs, whether relating to capacity, performance or data protection. VDS can also be used to attach a NAS device to a back-end SAN.

  • Page 34: Distributed File System (Dfs)

    Microsoft® Windows Storage Server 2003 White Paper Distributed File System (DFS) The Distributed File System enables the system administrator to create single hierarchical mapping of all systems and shares on the network. By uniting files on different computers into a single namespace, users do not have to sort through a network of dozens of servers, each with their own separate directory structure, but instead see the files as if they resided on a single computer.

  • Page 35: Nas Deployment Scenarios

    Microsoft® Windows Storage Server 2003 White Paper NAS Deployment Scenarios The following are common NAS deployment scenarios. • File Serving • Server Consolidation • Local and Remote Site Replication for Business Continuity • NAS-SAN Fusion File Serving Businesses need reliable file servers that can provide highly available data at a reasonable cost. Off- the-shelf, general-purpose servers are not typically configured with fully redundant hardware components.
  • Page 36 Microsoft® Windows Storage Server 2003 White Paper Figure 4. File serving between network clients and Windows Storage Server 2003.

  • Page 37: Server Consolidation

    Microsoft® Windows Storage Server 2003 White Paper Server Consolidation As companies add more and more servers to meet demands for increased storage capacity, equipment, licensing, maintenance (power, space, servicing) and management costs all escalate. Adding a Windows Storage Server 2003 based device to the network allows businesses to consolidate multiple file servers into a single more powerful NAS device.

  • Page 39: Nas-San Fusion

    Microsoft® Windows Storage Server 2003 White Paper NAS-SAN Fusion NAS devices can be seamlessly integrated into a storage area network, providing clients access to unlimited storage. In this configuration, NAS storage is separated from the NAS filing function and placed on the SAN. The NAS head now acts as a gateway to the SAN, controlling distribution of the data over the network and providing clients with maximum scalability and high-performance storage solutions.

  • Page 40: Summary

    Microsoft® Windows Storage Server 2003 White Paper Summary Windows Storage Server 2003 provides scalable, high performance storage solutions to businesses of all sizes. Built on the Windows Server 2003 operating system, this successor to Windows Powered NAS broadens usability and interoperability for both end users and system administrators. Using Shadow Copies for Shared Folders, end users are empowered to recover their own lost data without IT intervention, thereby improving their own efficiencies and helping the business save money.
