Theory of Operation
Overview
StorageWorks Secure Path is a high availability software product providing
continuous data access for Fibre Channel RAID Array 8000 / Enterprise
Storage Array 12000 storage systems configured on Sun Sparc platforms
running Solaris 2.6 or Solaris 7 (32-bit mode only).
Redundant hardware, advanced RAID technology and automated failover
capability are used to enhance fault tolerance and availability. Secure Path, in
conjunction with the StorageWorks RAID system, eliminates the following as
single points of failure: RAID controllers, disk drives, hubs, cables and host
bus adapters.
Figure 1-1 illustrates a basic Secure Path hardware configuration. Note the
physical connections that define the two separate paths, each originating at a
separate host bus adapter on a Solaris server and ending at a port on a separate
RAID controller on the storage system.
