Cisco Catalyst 4900M Switch is made for details middle community major-of-rack switching and midmarket collapsed core and aggregation layer deployment. Optimized for best deployment flexibility for the information center, the Cisco Catalyst 4900M is typically deployed for ten/a hundred/1000 or 1/10GBASE-T server access with 1:one uplink-to-downlink oversubscription and environments making use of a mix of 10/a hundred/1000 and ten Gigabit Ethernet servers or all ten Gigabit Ethernet servers.
Cisco Catalyst 4900M is genuinely a 320-Gbps, 250-million-packets-for each-second (mpps), two-rack-device (2RU) mounted-configuration switch with 8 fixed wire-velocity X2 ports on the base device and two optional 50 percent-card slots for deployment flexibility and financial investment safety. Small latency, scalable buffer memory, and superior availability with one+one scorching-swappable AC or DC electric power provides and a field-replaceable fan tray optimize the Cisco Catalyst 4900M for information and facts centers of any size.
For the midmarket collapsed core and aggregation layer and in the department workplace, the Cisco Catalyst 4900M gives an best resolution for space-constrained deployments that simply call for substantial-performance wire-pace expert services and superior availability. With all the unique semifixed architecture and enable in the Cisco TwinGig Converter Module, the Cisco Catalyst 4900M could be applied inside a collapsed core and aggregation layer LAN deployment, providing the overall flexibility to deploy Gigabit Ethernet now and amount-successfully migrate to ten Gigabit Ethernet as specs alter.
The Cisco Catalyst 4900M configuration offers wire-pace relationship, buffers to take care of bursty web-site readers, and a complete set of Layer three attributes vital at the collapsed core and aggregation layer of the community. The Cisco Catalyst 4900M also supports a suite of relieve-of-administration characteristics to simplify operations
The Cisco Catalyst 4948 ten Gigabit Ethernet Switch is seriously a wire-velocity, very low-latency, Layer 2 to 4, 1-rack-unit (1RU), fastened-configuration switch for rack-optimized server switching. Centered on the proven CiscoÂ® Catalyst 4500 Series components and program architecture, the Cisco Catalyst 4948 ten Gigabit Ethernet Switch gives excellent effectiveness, bandwidth, and reliability for lower-density, multilayer aggregation of superior-effectiveness servers and workstations. Substantial efficiency and scalability of intelligent community services is produced prospective with committed specialized sources known as ternary subject material addressable memory (TCAM). Sufficient TCAM means (sixty four,000 entries) allow superior function potential, supplying wire-pace routing and switching effectiveness with concurrent provisioning of solutions like excellent superior of services (QoS) and stability and aiding ensure scalability for todays community requirements with sufficient house for foreseeable future expansion.
The Cisco Catalyst 4948 10 Gigabit Ethernet Switch offers forty eight ports of wire-velocity 10/a hundred/1000BASE-T with two ports of wire-velocity 10 Gigabit Ethernet (X2 optics). Outstanding dependability and serviceability are delivered with optional inner AC or DC one+one hot-swappable energy provides and a incredibly hot-swappable fan tray with redundant. The 10 Gigabit Ethernet Switching for Large-Functionality, Rack-Optimized Server Switching
Wire-Velocity Efficiency in All Directions
The Cisco Catalyst 4948 ten Gigabit Ethernet Switch offers wire-pace throughput with small latency for information-intensive apps building use of a 136-Gbps changing material obtaining a forwarding rate of 102 million packets per 2nd (mpps) in components for Layer 2 to four customers. Large-performance switching is managed no make a difference the range of route entries or Layer a few and 4 companies enabled. Components-dependent Cisco Specific Forwarding routing architecture permits higher scalability and efficiency. X2 10 Gigabit Ethernet optics existing twenty Gigabit Ethernet wire-velocity uplinks for outstanding throughput of focused site visitors.
Power-Supply Redundancy for Nonstop Operation
The Cisco Catalyst 4948 ten Gigabit Ethernet Switch gives reliability for important applications with one+one redundant, very hot-swappable inner AC or DC electricity provides. The one+one power offer layout materials A-to-B failover when strength materials are linked to many circuits. AC and DC strength supplies is often combined within the identical device for fantastic deployment overall flexibility. The Cisco Catalyst 4948 10 Gigabit Ethernet Switch also characteristics a warm-swappable admirer tray with 4 redundant lovers for additional serviceability and availability.
