The Cisco Nexus 6001P (Figure 1) is a 1RU, 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 [QSFP] breakout cables) for Ethernet and FCoE traffic, with an overall throughput of 1.28 terabits per second (Tbps). The Cisco Nexus 6001P offers 48 fixed 1/10 Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) ports 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 6001P delivers low port-to-port latency of approximately 1 microsecond and low jitter independent of packet size using cut-through switching architecture and with features enabled.

Line-rate traffic throughput on all ports.
Cisco Nexus 6001P: 48 fixed 1/10 Gigabit Ethernet SFP+ and 4 fixed 40 Gigabit Ethernet QSFP+ports, with 10 and 40 Gigabit Ethernet FCoE support on all respective ports.
Cisco Nexus 6001T: 48 fixed 1/10 Gigabit BASE-T and 4 fixed 40 Gigabit Ethernet QSFP+ ports, with 10 and 40 Gigabit Ethernet FCoE support on all respective ports.
40 Gigabit Ethernet ports can be converted to 10 Gigabit Ethernet interfaces through QSFP+breakout cable.
