Routing use cases
This section describes use cases for routing.
SAN island consolidation and scaling
B-series routing consolidates SAN islands (multiple independent fabrics) into a Meta SAN. This modular
SAN design offers:
• Simplified scalability that allows you to scale a SAN without having to merge fabrics.
• Selective sharing of devices in different fabrics so that only devices required for specific functions
are seen across fabrics.
• Limited sharing or specific times for data migrations and storage consolidation.
• Ability to access equipment without changing its physical location. Connecting multiple fabrics to
8 Gb/s switches with integrated Fibre Channel routing, 1606 Extension SAN Switches or DC Dir
Switch MP Extension Blades, or MP Router or Blades enables sharing of devices located anywhere
in the Meta SAN.
• Ability to connect B-series fabrics using Secure Fabric OS.
• Ability to connect B-series and M-series fabrics in a Meta SAN. See Table 33 on page 121 for
supported fabric modes and firmware versions.
Routing does not merge fabrics, so existing zoning definitions and assigned domain IDs can be used
without modification. Duplicate zoning definitions and domain IDs in fabrics are hidden by the MP
Router. Fabrics in a Meta SAN can be scaled without affecting other fabrics.
Multiple SANs can be centralized and consolidated into one Meta SAN, or partitioned into different
administrative domains or different logical fabrics using the Virtual Fabrics feature as required. HP
recommends the use of Fabric Manager to simplify management procedures when implementing a
Meta SAN.
Figure 35 shows a typical configuration for SAN island consolidation.

Integration of Fibre Channel routing and FCIP
You can use the 1606 Extension SAN Switch or MP Router's integrated FCIP capability to extend
disaster-tolerant applications such as HP Continuous Access for storage arrays.
