Data storage system and method

Apparatus for transmitting and storing data from high speed data streams from a host computer comprising:

• a plurality of serially accessed storage devices in predetermined storage arrays coupled to said storage and access controllers receiving said high speed data streams from the host computer;
• higher speed random accessed storage means receiving said data for staging and storing the data on said serially accessed storage devices;
• a plurality of storage access controllers providing a redundancy of access and sequencing control to said high speed random accessed storage means;
• and
• means for controlling and correcting errors in the data streams transmitted between the serially accessed storage devices and the higher speed random accessed storage means;
• whereby a redundant, fault tolerant apparatus transmits and accessibly stores data from high speed data streams wherein slower speed serially accessed storage devices service higher speed random accessed storage means receiving high speed data streams from a host computer.

The method of transmitting high speed data streams comprising the steps of:

• providing a plurality of serially accessed storage devices in predetermined storage arrays transmitting said high speed data streams;
• providing a higher speed random accessed storage means for staging said data from said serially accessed storage devices;
• coupling a redundancy of access control and sequencing means including a plurality of storage and access controllers to said higher speed random accessed storage means;
• providing error correction means for said storage arrays coupled to said storage and access controllers for correcting errors resulting from failure of a storage array;
• and
• providing means for controlling and correcting errors in the data streams transmitted between the serially accessed storage devices and the higher speed random accessed storage means;
• whereby a redundant, fault tolerant method of transmitting and retrieving data from high speed data streams is provided wherein slower speed serially accessed storage devices service higher speed random accessed storage means receiving high speed data streams.
