Melio fs
Melio FS is a clustered file system designed specifically for SAN storage environments. It provides shared access to data on a SAN from multiple servers, enabling high availability, horizontal scaling of applications, and greatly simplified storage provisioning and management for virtual server environments. Users gain extensive new capability to utilize industry standard shared storage hardware, yet it is very simple to use.

Any user familiar with Windows disk administration tools can easily install and manage Melio. An installation on a small SAN can be done in 15 minutes. The only requirements for installation are Windows 2003, 2008, or 2008 R2 servers, iSCSI or Fibre Channel storage, and a TCP/IP network between the servers for lock traffic.

Melio FS was initially designed for very large scale clustered processing and file serving in telecom network operation centers. Its architecture is designed to support high availability computing, application scale-out using shared-data server clusters, and fast access to both small and large files. Melio FS incorporates multi-layer distributed locking mechanisms and advanced transaction managers, which provide performance, stability and reliability in very large storage environments. The symmetrical architecture, and advanced dynamic clustering capability provide both tremendous flexibility and reliability.

Melio incorporates Quality of Service management, so access to storage for specific servers can be given priority in storage-bandwidth constrained environments. Melio also provides reporting on I/O and transaction performance, which can be very useful in applications such as server virtualization that have a dependency on storage performance. Melio also includes distributed snapshot capability that can be used with any backup product utilizing a VSS client.
