What are the port configurations of the IBM QLogic 20-Port 4Gb Switch Module?

It features 20 Fibre Channel ports: 14 internal ports connecting to BladeCenter blades via midplane and 6 external autosensing ports at 4Gb/s. External ports support F_ports, FL_ports, or E_ports for fabric integration, with dual internal 100 Mbps Ethernet for management.

What speeds does this switch module support?

Ports operate at 1, 2, or 4 Gbps autosensing speeds, full-duplex. Internal ports match blade FC cards up to 4Gb/s in compatible chassis bays 3/4. It supports standards-based FC-SW2 for interoperability.

Which BladeCenter chassis is it compatible with?

Designed for IBM BladeCenter E, S, H, and HT chassis in switch bays 3 or 4. Provides 14 internal FC ports for blade connectivity and 6 external for SAN uplinks, ensuring seamless integration.

Does it support non-disruptive operations?

Yes, includes Non-Disruptive Code Load Activation (NDCLA) for firmware updates without downtime, plus Registered State Change Notification (RSCN) and power-on self-test diagnostics for reliable SAN management.

What protocols are supported?

Supports Fibre Channel Protocol SCSI (FCP-SCSI) and Fibre Channel Internet Protocol (FC-IP), enabling full-fabric mode for open-standards SANs. Operates in pass-thru or fabric modes for flexible deployments.

Is it suitable for existing SAN integration?

Yes, external ports connect to upstream switches or storage at 4Gb/s, with NPIV-like interoperability for non-disruptive BladeCenter addition to fabrics. Ideal for enterprise scalability without changes to core SAN management.
