  ERTFS – ProPlus64 – Functionality Highlights


Functionality Highlight


Terabyte file support

A 64-bit file interface shatters the 4 gigabyte file size barrier making it possible to create files that in theory could be 24 terabytes in length. In practice, the files are large enough for storing video and high volume streaming data on today’s 100 gigabyte plus disk drives

Failsafe operation

Eliminates volume corruption from power failures and media removals.

Zero disk latency

Guaranteed zero disk latency to follow or allocate cluster segments on file seek, file append, file read, file write. Operations occur at memory speeds except for data transfer interval.
The file pointer may be moved from anywhere to anywhere within a multi-terabyte file with virtually no overhead.

Real Time file IO operations

Files may be read written and extended incurring virtually no overhead allocating and tracking file extents.

Deterministic Asynchronous Operations

Provides asynchronous API calls to ensure smooth and deterministic operation

Programmer controlled extent management

Allows programmers to control fragmentation, pre-allocation of file extents and data placement.

Volume defragmenter subsystem

Defragmenter tool and monitor provided

Drop in support for Digital Video Recorder applications

Sophisticated circular data buffering and zero copy file extract routines allow easy creation of demanding DVR products

Real-time data logging routines

Provided for developing DVR applications or industrial, military or scientific streaming data applications.
