What ports does the Cisco WS-CBS3130X-S support?

It includes 4 external 10/100/1000BASE-T ports and 2 X2-based 10 Gigabit Ethernet uplink ports. High-speed stack connectors enable VBS integration, with optional SFP Gigabit via TwinGig converters. Management via RJ-45 console port. This configuration suits 10GbE fabric connections in Dell M1000e chassis.

What is the switching performance of this blade switch?

Features a 128-Gbps switching fabric with up to 59.2 mpps forwarding rate for 64-byte packets. Supports configurable MTUs to 9018 bytes for jumbo frames and 256 MB DDR SDRAM with 64 MB Flash. Optimized for reduced latency and high port density in Layer 2/3 operations.

Is this switch compatible with Dell M1000e chassis?

Yes, designed as a blade module exclusively for Dell PowerEdge M1000e enclosures. Dell PN HR521/WS-CBS3130X-S (replaces WN446). Integrates via fabric slots, providing up to 160 Gbps out-of-rack bandwidth with dual active links per blade server for high availability.

What QoS capabilities are available?

Supports wire-rate granular QoS with 802.1p CoS and DSCP classification, rate limiting to 8 Kbps CIR increments. Cross-switch QoS via VBS, using ACLs for source/destination IP/MAC/L4 TCP/UDP. Ensures prioritized traffic in demanding data center environments.

What power and form factor details apply?

Blade form factor for M1000e chassis slots, power consumption 12V at 6.25A (75W max). 19 LEDs including 12 for uplink status and 5 switch LEDs. Compact design with management console for out-of-band access via CLI, SNMP v1/v2c/v3.

How does VBS architecture benefit deployment?

Virtual Blade Switch (VBS) appears as a single node, simplifying Layer 2/3 topologies and reducing convergence times. Delivers dual active links doubling bandwidth per server, up to 160 Gbps rack output. Increases fabric stability and redundancy for enterprise blade clusters.
