Features and Benefits
Coupled with Cisco NX-OS, the Cisco Nexus 7000 Series
delivers a comprehensive set of features with nonstop operation in four
chassis form factors:
● 18-slot
chassis with 18 front-accessible module slots and side-to-side airflow
in a compact horizontal form factor with purpose-built integrated cable
management.
● 10-slot
chassis with 10 front-accessible vertical module slots and
front-to-back airflow and an integrated cable management system.
● 9-slot
with 9 front-accessible module slots and side-to-side airflow in a
compact horizontal form factor with purpose-built integrated cable
management.
● 4-slot
chassis with all front-accessible module slots and side-to-back airflow
in a small form factor with purpose-built integrated cable management.
A scalable, fully distributed fabric architecture
composed of up to five fabric modules combined with the chassis midplane
delivers up to 550 Gbps per slot for 8.8 Tbps, 9.9 Tbps, and 18.7 Tbps
of forwarding capacity in the 9-slot, 10-slot, and 18-slot switches,
respectively. The 4-slot chassis delivers up to 1.92 Tbps of forwarding
capacity in combination with the built-in fabric system.
The midplane design on the 9-slot, 10-slot, and 18-slot chassis and the backplane design on the 4-slot chassis support flexible technology upgrades as your needs change, providing ongoing investment protection.
Cisco Nexus 7000 4-Slot Switch Chassis
The Cisco Nexus 7000 4-Slot chassis with two I/O module
slots supports up to 96 x 1 and 10 Gigabit Ethernet ports, 12 x 40
Gigabit Ethernet ports and 4 x 100 Gigabit Ethernet ports, meeting the
needs of small to medium-size data centers, co-locations, access- and
aggregation-layer deployments, high-speed core deployments, and smaller
operation zones. The Cisco Nexus 7000 4-Slot chassis also has two
dedicated supervisor slots to provide full redundancy and high
availability. The 4-slot chassis does not require fabric modules. The
local I/O module fabrics are connected back to back to form a two-stage
crossbar that interconnects the I/O modules and the supervisor engines.
The backplane capacity is determined by the installed I/O modules.
● Side-to-rear
airflow increases the system density in a seven-rack-unit (7RU)
footprint, optimizing the use of rack space. The optimized density
provides the capability to stack up to six 4-slot chassis in a 42RU
rack.
● The
fan tray with built-in fan and controller redundancy helps ensure
reliability of the system and support for hot swapping of fan trays. The
fan tray is on the top side of the chassis and draws the air from the
right side of the chassis through the line card and supervisor slots and
propagates it through the empty space on the left side of the chassis.
The air then flows up to the fan tray on the top side and finally flows
out from the vent holes on the back side of the chassis.
● Even
though Nexus 7004 does not have fabric modules, fabric redundancy is
still provided. If the local fabric on one of the I/O modules fails, the
entire I/O module is taken offline.
● All modules, including power supplies and the fan tray, are accessible from the front.
Cisco Nexus 7000 9-Slot Switch Chassis
● The
Cisco Nexus 7000 9-Slot chassis with up to seven I/O module slots
supports up to 336 x 1 and 10 Gigabit Ethernet ports, 42 x 40 Gigabit
Ethernet ports, and 14 x 100 Gigabit Ethernet ports, meeting the demands
of mission-critical campus core and data center deployments. It has two
dedicated supervisor slots to provide full redundancy.
● Side-to-side
airflow increases the system density in a 14RU footprint, optimizing
the use of rack space. Theoptimized density provides the capability to
stack up to three 9-slot chassis in a 42RU rack.
● Independent
variable-speed system and fabric fans provide efficient cooling
capacity to the entire system. Fan-tray redundancy features help ensure reliability of the system and support for hot swapping of fan trays.
● I/O
modules, supervisor modules, and fabric modules are accessible from the
front. Power supplies and fan trays are accessible from the back.
Cisco Nexus 7000 10-Slot Switch Chassis
● The
Cisco Nexus 7000 10-Slot chassis with up to eight I/O module slots
supports up to 384 x 1 and 10 Gigabit Ethernet ports, 48 x 40 Gigabit
Ethernet ports, and 16 x 100 Gigabit Ethernet ports, meeting the demands
of large data center deployments. It has two dedicated supervisor slots
to provide full redundancy.
● Front-to-back
airflow helps ensure that use of the Cisco Nexus 7000 10-Slot chassis
addresses the requirement for hot-aisle and cold-aisle deployments
without additional complexity.
● The
system uses dual system and fabric fan trays for cooling. Each fan tray
is redundant and composed of independent variable-speed fans that
automatically adjust to the ambient temperature, helping reduce power
consumption in well-managed facilities while helping enable optimum
operation of the switch. The system design increases cooling efficiency
and provides redundancy capabilities, allowing hot swapping without
affecting the system; if either a single fan or a complete fan tray
fails, the system continues to operate without a significant degradation
in cooling capacity.
● The
system supports an optional air filter to help ensure clean air flow
through the system. The addition of the air filter satisfies Network
Equipment Building Standards (NEBS) requirements.
● I/O
modules and supervisor modules are accessible from the front, and
fabric modules, power supplies, and fan trays are accessible from the
back.
Cisco Nexus 7000 18-Slot Switch Chassis
● The
Cisco Nexus 7000 18-Slot chassis with up to 16 I/O module slots
supports up to 768 x 1 and 10 Gigabit Ethernet ports, 96 x 40 Gigabit
Ethernet ports, and 32 x 100 Gigabit Ethernet ports, meeting the demands
of the largest data center deployments. It has two dedicated supervisor
slots to provide full redundancy.
● Side-to-side
airflow increases the system density in a 25RU footprint, optimizing
the use of rack space. Theoptimized density provides more than 16RU of
free space in a standard 42RU rack for cable management and patching
systems.
● Independent
variable-speed system and fabric fans provide efficient cooling
capacity to the entire system. Fan-tray redundancy features help ensure
reliability of the system and support for hot swapping of fan trays.
● I/O
modules and supervisor modules are accessible from the front, and
fabric modules, power supplies, and fan trays are accessible from the
back.
Cisco Nexus 7000 Series Chassis Common Components
All Cisco Nexus 7000 Series chassis have the following components:
● Integrated
cable management system designed to support the cabling requirements of
a fully configured system at either or both sides of the switch,
allowing outstanding flexibility. All system components can easily be
removed with the cabling in place, providing ease of maintenance tasks
with little disruption.
● A
series of LEDs at the top of the chassis provide a clear summary of the
status of the major system components, alerting operators to the need
to conduct further investigation. These LEDs report the power supply,
fan, fabric, supervisor, and I/O module status.
● A
purpose-built optional front-module door provides protection from
accidental interference with both the cabling and modules installed in
the system. The transparent front door allows easy observation of
cabling and module indicators and status lights without any need to open
the doors, reducing the likelihood of faults caused by human
interference. The door supports a dual-opening capability for flexible
operation and cable installation while fitted. The door can easily be
completely removed for both initial cabling and day-to-day management of
the system.
Energy-Efficient Design
The Cisco Nexus 7000 Series uses power supplies that
are up to 90 percent efficient, so less power is wasted as heat, and
more power is available for the system to use than with typical power
supplies.
The fan modules in the chassis adjust to compensate for
changing thermal characteristics. At lower speeds, they use less power.
In the 9-slot chassis, the fan tray is designed to completely turn off
the power for a row of fans when the corresponding slots are unused.
Consolidation of multiple switches in the Cisco Nexus
7000 Series is enabled by the powerful combination of high density and
performance, support for device virtualization, and comprehensive
reliability and availability features. This consolidation increases the
power efficiency by reducing wasted power from multiple partially loaded
and inflexible systems.
