Host systems attachment overview

The DS6000™ storage unit provides a variety of host attachments so that you can consolidate storage capacity and workloads for open-systems hosts, S/390^® hosts, and eServer™ zSeries^® hosts.

You can configure the storage unit for fibre-channel adapters, for support of Fibre Channel Protocol (FCP) and fibre connection (FICON^®) protocol .

For fibre-channel attachments, you can establish zones. The zones must contain a single port that is attached to a system adapter with the desired number of ports that are attached to the storage unit. By establishing zones, you reduce the possibility of interactions between system adapters in switched configurations. You can establish the zones by using either of two zoning methods:

Port number
Worldwide port name

You can configure switch ports that are attached to the storage unit in more than one zone. This enables multiple host system adapters to share access to the storage unit fibre-channel ports. Shared access to a storage unit fibre-channel port might come from host platforms that support a combination of bus adapter types and the operating systems.
