Common Topologies; Transparent Routing; Six-Switch Stack - HP StorageWorks SN6000 Installation And Reference Manual

Figure 12 shows a six-switch stack of model SN6000 switches using eight XPAK switch stacking cables.
120 SFP ports are available for devices.

Common topologies

Although HP recommends using the XPAK stacking ports to achieve the highest cabling efficiency and
bandwidth, you can also create multiple switch configurations using the SFP ports. The HP StorageWorks
SN6000 Fibre Channel Switch switch supports the following topologies using the SFP ports:
• Cascaded fabric topology
• Ring fabric topology
• Meshed fabric topology
• Core-edge fabric topology
For additional information about topologies and Storage Area Network (SAN) connectivity, see the SAN
Design Reference Guide available at the HP website: http://www.hp.com/go/SANdesignguide.

Transparent routing

IMPORTANT:
Channel Switches with active TR_Ports; however, SSCM cannot manage or discover remote switches or
devices in the remote fabric. Use QuickTools and the storage management interface to present Logical Unit
Numbers (LUNs) to remote devices. SSCM displays the remote fabric as a grayed-out switch, and no
management can be performed. SSCM version 3.0 or later is required for the HP SN6000 Fibre Channel
Switch. SSCM version 2.0 and earlier versions do not support the management of fabrics that include
switches with active TR_Ports and may disrupt communication between an SN6000 or 8/20q Fibre
Channel Switch and the remote fabric.
The transparent routing feature provides inter-fabric routing to allow controlled and limited access between
devices on a SN6000 Fibre Channel Switch (local) fabric and devices on a remote fabric consisting of
B-series or C-series switches. For a list of switches that are supported in a remote fabric, see the HP
StorageWorks SN6000 Fibre Channel Switch Release Notes, and the HP StorageWorks SAN Design
Reference Guide on the HP website: http://www.hp.com/go/sandesignguide. This type of inter-fabric
connection uses the Fibre Channel industry N-Port ID Virtualization (NPIV), and makes local and remote
devices accessible to each other while maintaining the local and remote fabrics as separate fabrics.
