SAN requirements and considerations

These requirements and considerations can help you plan for a DS8000® series that attaches to a SAN.

A Fibre Channel storage area network (SAN) is a specialized, high-speed network that attaches servers and storage devices. With a SAN, you can perform an any-to-any connection across the network using interconnect elements such as routers, gateways, hubs, and switches.

For a DS8000 series configuration, you can use SANs to attach storage unit disks and to attach hosts to the storage unit.

When you connect your DS8000 storage units to a SAN, you must meet the following requirements:

Also consider the following facts:
  • Fibre Channel SANs can provide the capability to interconnect open systems and storage in the same network as System z® or S/390® host systems and storage.
  • A single Fibre Channel I/O adapter can have physical access to multiple Fibre Channel ports on the storage unit.
