Fibre-channel host attachment

This section provides an overview of fibre-channel attachment to a DS6000™, including architecture, topology, and LUN access modes.

• 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.
• Fibre-channel architecture
  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.
• Fibre channel cables and adapter types
  This section provides information about fibre-channel cables and adapter types.
• Fibre-channel node-to-node distances
  The storage unit supports fibre-channel adapter for extended node-to-node distances.
• LUN considerations for fibre-channel attachment
  You can use a WWPN to associate a LUN for fibre-channel attachment.
• LUN access modes for fibre-channel attachment
  This section describes two LUN fibre-channel access modes: access-any and access-restricted. As well, an overview of access profiles and anonymous hosts is provided.
• Fibre-channel storage area networks
  Fibre-channel storage area networks connect servers and storage devices.
• Fibre-channel worldwide port name identification
  The DS6000 uses a worldwide port name (WWPN) to uniquely identify a host port that is connected to a storage unit. The WWPN consists of exactly 16 hexadecimal characters (0 - 9 and A - F).
• Open-systems hosts with fibre-channel adapters
  You can attach a DS6000 series to an open-systems host with fibre-channel adapters.
