HP StorageWorks Secure Path for Windows Workgroup Edition provides continuous data access for RAID storage systems on Windows 2000 and Windows NT platforms. It allows HP's RAID storage systems to be cabled on two independent busses, using two separate host bus adapters in a single server. When combined with the inherent fault-tolerant features of the RAID Array, this configuration effectively eliminates single points of failure in the storage system. Should a failure on one path's host bus adapter, cable, or controller occur, the failure is detected and I/O is automatically re-routed to the functioning, alternate path. This process is called failover, and requires no resource downtime and ensures high availability of data. Failed-over storage units may be failed-back, through use of a configuration management utility, once failed components have been replaced.??Secure Path V4.0C for Windows Workgroup Edition supports the MSA1000 and the VA solutions
