Standards compliance HP products conform to these standards in a manner consistent with accepted engineering practices and procedures. In certain cases, HP may add proprietary supplemental functions to those specified in the standards. We verify conformance with Fibre Channel Standards by subjecting our switches to SANmark Conformance Tests developed by the Fibre Channel Industry Association. Our switches have earned the SANmark logo indicating such conformance.

SAN Switch platform support The SAN Switch has the following characteristics: • Passive air cooling • 256 MB compact flash • Eight internal 2 Gb/sec FC server Blade ports (2 Gb/sec default speed) with the following characteristics: • Automatic negotiation to the highest common speed of all servers connected to port • Universal and self-configuring ports, which are capable of becoming an F_Port (fabric enabled) or FL_Port (fabric loop enabled) • Four external 1/2/4 Gb/sec FC small form-factor pluggable (SFP)
• Identification to HP chassis management via HP specified SEEPROMs • Dynamic path selection (DPS) with the exchange-based and device-based polices. The SAN Switch uses the exchange information to determine the routing paths dynamically. Reliability Fabric OS 5.0.0 features RSCN suppression which is the ability to control RSCNs that originate from hosts on a port-by-port basis. Problem determination Fabric OS 5.0.
Long-distance enhancements Table 1 provides the maximum distances available on E_Ports when the four external E_Ports are available for long-distance connections. Note that these distances would be achieved under ideal circumstances; actual maximum distances might be lower for a given distance and port speed.

Documentation updates The HP StorageWorks Fabric OS 5.0.0 addendum is new to the switch documentation set and lists all changes to the standard switch documentation set. The user and reference guides for OS 4.x are identical in content to OS 5.0.0 unless noted otherwise in the addendum. These same changes are listed in Chapter 1 of each guide in a section entitled “Changes to this guide for OS v5.0.0.
