What is the switching capacity and port configuration of HPE QW938B?

The HPE QW938B SN3000B offers 768 Gbit/s full-duplex throughput with 24 active SFP+ ports supporting 4/8/16 Gbps speeds. Any eight ports can trunk for 128Gb ISLs, enabling non-blocking wire-speed forwarding ideal for dense SAN deployments with high east-west traffic.

How does D_Ports benefit SAN management on this switch?

D_Ports allow administrators to isolate optics/cable faults, test latency, distance, and signal integrity without disrupting fabrics. This reduces deployment times and diagnostics, supporting proactive maintenance in large-scale enterprise SANs with minimal downtime.

What management protocols does the QW938B support?

Supports SNMP v1/v3, Telnet, SSH-2, HTTP/HTTPS, SMI-S for remote management. Integrates with SAN Network Advisor for fabric-wide monitoring, configuration, and best-practices validation across B-series switches, directors, and HBAs.

Is the HPE QW938B suitable for virtualized environments?

Yes, it excels in highly virtualized setups with broad 4-16 Gbps support, DPS for path optimization, QoS prioritization, and high ISL performance. Scales to 24 ports in 1U, protecting investments while handling cloud-optimized workloads efficiently.

What power and environmental specs does it have?

Typical 80W consumption from single 85-264V AC PSU, operates 0-40°C at 10-85% humidity up to 3000m altitude. 1U form (438x443x43mm, 7.82kg) with rack kit fits standard data center racks reliably.

How does it compare to previous FC switches?

16Gb ISLs provide twice the performance of 8Gb generations, requiring fewer ports/cables/power for equivalent bandwidth. Aggregate 768Gb throughput and DPS ensure superior load balancing and fabric efficiency in modern SANs.

Product overview

The HPE QW938B, model SN3000B 16Gb 24-port/24-port Active Fibre Channel Switch, provides market-leading 16Gb/s Fibre Channel technology for hyper-scale private cloud and highly virtualized storage environments. It scales from 12-24 ports in a compact 1U rack-mountable design, supporting 4/8/16 Gbps speeds with 768 Gbit/s full-duplex throughput. Key features include high-speed 16Gb ISLs for doubled performance over prior generations, reducing links, cables, power, and ports. Diagnostic Ports (D_Ports) enable rapid fault isolation for optics, cables, latency, and distance. Exchange-based Dynamic Path Selection (DPS) optimizes load balancing across fabrics. Ideal for enterprise SANs, it offers RADIUS/LDAP authentication, SNMP/Telnet/SSH management, and SAN Network Advisor integration for comprehensive monitoring and diagnostics. With low-latency transfers and trunking up to 128Gb ISLs, it ensures reliable connectivity for servers, storage arrays, backups, and disaster recovery in data centers.
