Note: FICON host channels support more devices than the 4096 possible devices
on a storage unit. This enables you to attach other control units or other
storage units to the same host channel up to the limit that the host supports.
The storage unit supports the following operating systems for S/390 and zSeries
hosts:
v
Transaction Processing Facility (TPF)
v Virtual Storage Extended/Enterprise Storage Architecture (VSE/ESA
™
)
v z/OS
®
v
z/VM
®
v Linux
™
For details about models, versions of operating systems, and releases that the
storage unit supports for these host systems, see the Interoperability Matrix at

General information about attaching to open-systems host with
fibre-channel adapters
You can attach a storage unit to host systems with fibre channel-adapters.
Fibre-channel architecture
Fibre-channel architecture provides communications protocols on the storage unit.
The storage unit provides a fibre-channel connection in the storage unit. For more
information about hosts and operating systems that the storage unit supports on the
fibre-channel adapters, see the Interoperability Matrix at
http://www.ibm.com/servers/storage/disk/ds6000/interop.html.
Fibre-channel architecture provides a variety of communication protocols on the
storage unit. The units that are interconnected are referred to as nodes . Each node
has one or more ports.
A storage unit is a node in a fibre-channel network. Each port on a storage unit
fibre-channel host adapter is a fibre-channel port. A host is also a node in a
fibre-channel network. Each port attaches to a serial-transmission medium that
provides duplex communication with the node at the other end of the medium.
Storage unit architecture supports these basic interconnection topologies (network
structure):
v
Point-to-point
v Switched fabric
Point-to-point topology
The point-to-point topology, also known as direct connect, enables you to
interconnect ports directly. Figure 1 on page 13 shows an illustration of a
point-to-point topology.
