Sanbolic Accelerates Clustered NAS Performance with Network Oplocks.Support for Client-side Network Write Caching in Melio FS Increases Performance more than 10x for Write Intensive File Serving Workloads WATERTOWN, Mass. -- Sanbolic, Inc., a leading developer of software to simplify and share SAN storage, today announced a new component of Melio cluster file system which greatly improves the efficiency of network operations, resulting in much faster performance in clustered NAS (1) See network access server. (2) (Network Attached Storage) A specialized file server that connects to the network. A NAS device contains a slimmed-down operating system and a file system and processes only I/O requests by supporting the popular systems for write intensive applications using network file serving installations. Using Melio FS, multiple Windows Storage Server A Windows-based network attached storage (NAS) operating system from Microsoft. Originally released as Windows Powered NAS, Windows Storage Server provides file and print sharing, but does not execute applications. As of Windows Storage Server 2003, it also stores Exchange Server data. See NAS. file serving appliances can be clustered into a common file system on external SAN storage. All Storage Servers have concurrent read and write access to the shared storage using Sanbolic's clustered file system A clustered file system is a file system which is simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system. , so a file call can be processed by any of the Storage Servers. Melio FS now fully implements the network redirector (networking) network redirector - An operating system driver that sends data to and receives data from a remote device. A network redirector often provides mechanisms to locate, open, read, write, and delete files and submit print jobs. oplock protocol which defines the interaction between the file system and the network sharing service. This enables the clients to cache via their network redirector in clustered file serving installations and greatly improves performance in network operations such as file open, file attributes A file access classification that determines how a file can be viewed or whether it can be edited. File attributes are maintained in the file system's directories, and typical attributes are Read-Only, Hidden, System and Archive. updates, and file data write. This architecture yields enormous increase in performance as network communication is no longer required for each operation. For example, an application writing 200 bytes blocks would not wait for a network round-trip time round-trip time - (RTT) A measure of the current delay on a network, found by timing a packet bounced off some remote host. This can be done with ping -s. for each write, but the data would be grouped and sent asynchronously to the Storage Server running Melio FS, without blocking the application. "Sanbolic has worked with Microsoft to integrate new network oplock technology into clustered file serving systems utilizing the Microsoft Windows See Windows. (operating system) Microsoft Windows - Microsoft's proprietary window system and user interface software released in 1985 to run on top of MS-DOS. Widely criticised for being too slow (hence "Windoze", "Microsloth Windows") on the machines available then. Storage Server platform and Melio cluster file system," said Bala Kasiviswanathan, director of storage solutions marketing at Microsoft. "This enhancement provides greater scalability of the performance of Windows Storage Server based file serving solutions for demanding write-intensive applications." Sanbolic software currently supports Microsoft Windows 2000 Server, Microsoft Windows XP, Microsoft Windows Vista, and Microsoft Windows Server 2003 R2. Sanbolic distributes its product solutions worldwide through a network of distributors, OEMs, VARs and system integrators. Sanbolic will be exhibiting at the Microsoft Worldwide Partner Conference Booth No. 134 in Denver July 10-12. About Sanbolic, Inc.
