FICON-attached zSeries hosts

The DS6000™ series supports FICON-attached and zSeries^® hosts.

The storage unit attaches to S/390^® and zSeries host systems with FICON™ channels. Each storage unit fibre-channel adapter has one port. You can configure the port to operate with the FICON upper-layer protocol. When configured for FICON, the fibre-channel port supports connections to a maximum of 128 FICON hosts. On FICON, the fibre-channel adapter can operate with fabric or point-to-point topologies. With fibre-channel adapters that are configured for FICON, the DS6800 series supports the following:

Either fabric or point-to-point topologies
A maximum of 128 channel connections per fibre-channel port
A maximum of 32 logical subsystems
A maximum of 8192 logical volumes
A maximum of 1040 volume groups

The DS6800 supports the following operating systems for zSeries hosts:

Transaction Processing Facility (TPF)
Virtual Storage Extended/Enterprise Storage Architecture (VSE/ESA™)
z/OS^®
z/VM^®

FICON is an optional feature on the DS6800 system, and is available with the FICON Attachment feature number 5915.
