Host Connection Topology

There is no direct association between host ports and drive channels. Drives are associated with host port IDs as the logical configuration of drives, e.g., a logical drive. A logical drive can be composed of drives on different drive channels, and a logical drive can be associated with target IDs on different host ports.

Drive access contention (that may happen when two (2) host computers can access the same array) and data-path failover activities should be handled by a third-party software running on host computer(s).

RAID subsystem host channel SCSI connectors are connected to the servers via host bus adapters (HBAs) that have been installed on the host computer(s).

Single server connection: If a single logical drive is mapped to a single server, a RAID management software should be installed in the server to execute RAID functionality.

Multiple server connection: If a single logical drive is mapped to two (2) separate servers through dual-redundant data paths, separately purchased, third-party multipathing and clustering software must be installed on both servers. The clustering software will ensure that if one (1) server or the data path to a single server fails, the second server will con- tinue to provide access to the data.
