<p>A redundant disk computer system (100) providing targeted data broadcast on the data bus (72) to a plurality of devices on the data bus (72), such as computer central memory (60) and a plurality of storage media disks (parity (50) and data (55)) under control of a real time operating system. The redundant array computer operating system (100) provides the control and selected designation of the disk adapters (95) as targeted receivers to read data 'broadcast' over the data bus, providing simultaneous transfer of data over the data bus (72). Each enhanced disk adapter further includes exclusive-OR logic (93A) thereon to provide direct calculation of parity from the newly received data and a subsequently received old data on a single subsequent data bus cycle.</p> |
