• Optimized for virtualization and cloud deployments
  The data center today must meet the demands of virtualization and cloud-based computing. High-performance servers deployed in the cloud can support many more virtual machines and workloads than ever before. The requirement to deploy more servers on demand puts additional strain on the network fabric. The Cisco Nexus 6001 addresses this challenge by providing scalability and performance, making it an excellent platform for meeting current and future needs.
• Density and resilience
  Built for today's data centers, the switches are designed just like the servers they support. Ports and power connections are at the rear, close to server ports, helping keep cable lengths as short and efficient as possible and delivering to rack servers benefits traditionally offered only on blade servers. Hot-swappable power and fan modules can be accessed from the front panel, where status lights offer an at-a-glance view of switch operation. Front-to-back or back-to-front cooling is consistent with server designs, supporting efficient data center hot- and cold-aisle designs. Serviceability is enhanced with all customer-replaceable units accessible from the front panel.
• Energy efficiency
  The Cisco Nexus 6001 helps data centers operate within their space, power, and cooling parameters while reducing their carbon footprints. The switch power supplies are also capable of maintaining 90 percent efficiency at load conditions of as low as 25 percent utilization. This capability allows the switch to make efficient use of power while still being appropriately sized to support the conditions of a full system load.
• Intelligent Cisco Switched Port Analyzer (SPAN) and Encapsulated SPAN (ERSPAN)
  SPAN and ERSPAN can be used for troubleshooting and robust monitoring of traffic. The SPAN and ERSPAN capabilities in the Cisco Nexus 6001 are nondisruptive, with only extra bandwidth capacity used for SPAN and ERSPAN traffic. SPAN and ERSPAN traffic is categorized as best effort, and in the event of link congestion, SPAN and ERSPAN traffic is dropped first. Enhancements include more efficient allocation of bandwidth to SPAN and ERSPAN traffic whereby any fabric bandwidth not used for data traffic can be allocated to SPAN or ERSPAN traffic. The switch can support up to 31 line-rate SPAN and ERSPAN sessions.
• Multicast enhancements
  The Cisco Nexus 6001 supports line-rate layer 2 and 3 multicast throughput for all frame sizes. The Cisco Nexus 6001 offers optimized multicast replication through the fabric and at the egress point. The large buffers allow absorption of bursty traffic. Support is provided for 32,000 multicast routes and for Internet Group Management Protocol (IGMP) snooping tables in hardware. Multicast enhancements include flow-based hashing for multicast traffic over a PortChannel and enhanced Bidirectional Protocol-Independent Multicast (Bidir-PIM) support. The switch also supports IP-based forwarding for IGMP snooping.

The Cisco Nexus 6001T switch is a 1 RU 10 and 40 Gigabit Ethernet switch offering wire-speed performance for up to sixty-four 10 Gigabit Ethernet ports (using Quad Small Form-Factor Pluggable breakout cables) for Ethernet and FCoE traffic, with an overall throughput of 1.28 terabits per second. The Cisco Nexus 6001T offers 48 fixed 1/10G BASE-T and four 40 Gigabit Ethernet QSFP+ ports. Each 40 Gigabit Ethernet port can be split into four 10 Gigabit Ethernet ports using a QSFP breakout cable. The Cisco Nexus 6001T delivers low port-to-port latency of approximately 3.3 microsecond and low jitter independent of packet size using cut-through switching architecture and with features enabled. QSFP interface supports 1 microsecond latency. The hardware of 6001T is capable of supporting FCoE over 10G BASE-T interface.
The Cisco Nexus 6001T can be deployed in multiple scenarios - direct-attach 10 and 40 Gigabit Ethernet server access and high-density fabric extender aggregation deployments, leaf and spine designs, and compact aggregation - to build scalable Cisco Unified Fabric across a diverse set of physical and virtual server environments in the data center.
