81. e Guide 15 2 2 4 Multiple Data and Control Paths The 9900 subsystem uses a state of the art architecture called the Hierarchical Star HiStar Network HSN which utilizes multiple point to point data and command paths in order to provide redundancy and improve performance Each data and command path is independent The individual paths between the channel or disk adapters and cache are steered by high speed cache switch cards The 9900 does not have any common buses thus eliminating the performance degradation and contention that can occur in a bus architecture All data stored on the 9900 subsystem is moved into and out of cache via the redundant high speed paths 2 2 5 Redundant Power Supplies Each storage cluster is powered by its own set of redundant power supplies and each power supply is able to provide power for the entire subsystem if necessary Because of this redundancy the 9900 subsystem can sustain the loss of multiple power supplies and still continue operation To make use of this capability the 9900 should be connected either to dual power sources or to different power panels so if there is a failure on one of the power sources the 9900 can continue full operations using power from the alternate source 2 2 6 Client Host Interface Processors CHIPs and Channels The CHIPs contain the front end microprocessors which process the channel commands from the host s and manage host access to cache In the S 390 environment t
