Integrating San Technology; Fibre Channel Topologies - HP Surestore 64 - Director Switch Planning Manual

•
Scalability to meet growth requirements. A director with planned excess port capacity
provides OSI connectivity for future servers, devices, and applications. Refer to
Capacity Planning on page 53 for additional information.
As part of the director planning and installation process, define the enterprise's computing
assets (operating systems, hardware, communication networks, database management
systems, and business applications), and document all business and technical issues to be
addressed. Ensure these issues are considered and the resulting implications are factored
into the director installation and SAN implementation plan.

Integrating SAN Technology

Prior to director installation in a Fibre Channel SAN configuration, examine and document
the enterprise's topology and physical infrastructure. In particular:
• Ensure fiber-optic cables with small form factor pluggable (SFP) LC connectors are
installed and documented, and are of sufficient length to meet planned distance
requirements. Refer to Task 2: Plan Fiber-Optic Cable Routing on page 89 for additional
information.
•
Determine if the SAN design will coexist with or replace the existing topology, and
ensure director interoperability with end devices provided by separate original
equipment manufacturers (OEMs). Refer to Task 3: Consider Interoperability with
Fabric Elements and End Devices on page 90 for additional information.
• Document existing device node names and internet protocol (IP) addresses, along with
naming and address assignment conventions. Refer to Task 6: Plan Network Addresses
on page 93 for additional information.

Fibre Channel Topologies

The Fibre Channel director supports both point-to-point and multiswitch fabric topologies,
and indirectly supports arbitrated loop topology. A combination of these topologies (hybrid
topology) is also supported.
