High-performance, low latency flexible design to help migrate to 10Gb
Organizations seeking a top-of-rack switch that delivers the buffering, latency and performance characteristics necessary to excel in that role.
HighlightsThe Cisco® Catalyst® 4900M is a two-rack-unit (2RU) top-of-server rack Ethernet switch optimized for 10/100/1000 and 10 Gigabit Ethernet access devices. It is unique in the top-of-rack space because it is semi-fixed. This flexibility provides a simplified modular migration path from Gigabit Ethernet to 10 Gigabit Ethernet.
Fast, Reliable 10 Gbit/sec Performance
- Simplified and flexible infrastructure provides 10 Gigabit Ethernet configurations ranging from 8 to 24 ports
- Offers more than nine combinations of media types, including Gigabit Ethernet ,copper and fiber interfaces and 10 Gigabit Ethernet copper and fiber interfaces
- Delivers an investment protection path for 10GBASE-T access upgradability
- Offers wire-speed Layer 2+ Ethernet switching with 320 Gbps and 250 million packets per second (mpps) of aggregate capacity in 2RU
- Eliminates access port–to–uplink-port oversubscription bottlenecks with up to 40 ports of wire-speed 10/100/1000 at the access to 8 wire-speed 10 Gigabit Ethernet uplinks
- Provides Cisco TwinGig Converter Module support on the 8-port X2 half-cards, allowing up to 32 Gbps over fiber optics per switch
- Allows control of transmit queue sizing: default size of TX queue is 8000 packets (irrespective of packet size); this can be configured into up to 8 queues with different sizes and graded priorities
