What port configuration does the HPE QW940B provide?

The HPE QW940B SN8000B features 32 SFP ports supporting 4/2/1Gbps auto-negotiating to 8Gbps full-duplex Fibre Channel. This blade design fits HPE c-Class enclosures, enabling high-density SAN connectivity without external switches for up to 16 blades per chassis.

Is the QW940B suitable for VMware environments?

Yes, it supports N_Port ID Virtualization (NPIV) allowing multiple WWNs per physical port for VMware vSphere. Combined with zoning and QoS, it ensures prioritized access to FC storage for virtual machines in blade servers.

What chassis is compatible with this FC switch blade?

Designed for HPE BladeSystem c-Class enclosures including c7000 and c3000. Installs in interconnect bays with shared power and management via Onboard Administrator or Virtual Connect.

Does it support inter-switch links for fabrics?

Yes, E_Port ISL trunking up to 8Gbps with VE ports enables multi-switch fabrics. Supports up to 239 switches per fabric with advanced features like fabric-wide QoS and security.

What management options are available?

Managed via HPE B-series Fabric OS (FOS) through CLI, web GUI, or HPE SAN Network Advisor. Includes SNMP, SMI-S, and RADIUS for centralized enterprise SAN monitoring.

Can ports be expanded beyond 32?

Ports-on-demand licensing allows activation from 16 to 32 ports. Fabric expansion via ISLs; no optical port expansion modules as it's fixed blade configuration.
