Extreme Networks Data Sheet: Summit X670-48t
Technical Specifications
40 Gigabit Ethernet Uplinks and
High-Speed 160 Gbps Stacking
The Summit X670V-48t switch can support an additional four QSFP+ ports
of 40 GbE with the optional VIM4-40G4X module. With this option, you
can maximize the number of interfaces for servers up to 48 ports while
using the dedicated four-port 40 GbE module for uplink connectivity. The
optional VIM4-40G4X provides 160 Gbps aggregated bandwidth to the
backbone. Each 40 Gigabit Ethernet port can be independently configured
as 40 Gigabit Ethernet or 4 x 10 Gigabit Ethernet; thus with the VIM4-
40G4X module, Summit X670V-48t can support up to 64 ports of 10
Gigabit Ethernet in a 1RU form factor and is capable of Layer 2 and Layer 3
forwarding at up to 960 million packets per second forwarding rate. This
configuration provides 3:1 oversubscription from front ports (total 480
Gbps bandwidth) to uplink ports (total 160 Gbps bandwidth) and
maximizes server port density.
Summit X670V-48t together with VIM4-40G4X provides high speed
stacking options running at 160 Gbps or 320 Gpbs through the
SummitStack technology. SummitStack-V160 can be enabled on two 40
Gigabit Ethernet QSFP+ ports on the VIM4-40G4X, using half of the
module’s four ports as stacking interfaces. SummitStack-V320 can be
enabled on all four 40 Gigabit Ethernet QSFP+ ports on the VIM4-40G4X,
using all of the module’s four ports as stacking interfaces.
SummitStack-V320 on the X670 is compatible with SummitStack-V320 on
Summit X480 and Summit X650 series switches. SummitStack-V160 on the
X670 is compatible with SummitStack-V160 on Summit X480 and Summit
X650 series switches and is also compatible with SummitStack-V80, which
is available for Summit X460 and Summit X480 series switches.
Green Design
The Summit X670 series is designed to be environmentally green. System
power consumption is very low at both high-load and idle situations
through the power-ecient hardware design. The power supplies are also
highly ecient, which minimizes the loss of power and unnecessary heat
generated by the power supply. Summit X670 series switches can be used
in AC or DC powered environments.
Supports Virtualized Data Centers
With the optional feature pack, Summit X670 switches can also support
Direct Attach™ (VEPA), which eliminates the virtual switch layer, simplifying
the network and improving performance. Direct Attach enables data center
simplification by reducing network tiers from 4 or 5 tiers to just 3 or 2 tiers,
depending on the size of the data center.
To further enhance data center operations, Summit X670 switches support
XNV™ (ExtremeXOS Network Virtualization), which is natively supported in
the ExtremeXOS operating system and is a licensable feature pack for
Ridgeline™, a network and service management application, sold
separately. XNV provides insight, control and automation for virtualized
data centers.
Summit X670 switches also support Priority-based Flow Control (PFC, or
IEEE 802.1Qbb), which allows network trac to be controlled
independently based on Class of Service. PFC allows network trac that
requires lossless throughput to be prioritized, while other trac types that
do not require or perform better without PFC can continue as normal.
Software Defined Networking (SDN)
ExtremeXOS implementations of OpenFlow APIs allow an external
OpenFlow-based SDN controller to access and control the forwarding
plane of ExtremeXOS network devices. ExtremeXOS-based switches oer a
programming interface through OpenFlow to enable high degree of
automation in provisioning network services for many upper layer business
critical applications running the OpenFlow-based SDN controller.
Extreme XOS-based switches also allow for integration with the OpenStack
open source cloud computing platform for public and private clouds
through the Extreme Networks Quantum plugin. The plugin provides a
scalable, automated, rich API-driven system that enables networking-as-a-
service model managing data center interconnect solutions and large
multi-tenant networks.
Audio Video Bridging (AVB)
ExtremeXOS supports IEEE Audio Video Bridging (AVB) standards to
enable reliable real-time audio and video transmissions over Ethernet, for
high-definition and time-sensitive multimedia streams with assigned
Quality of Service (QoS). ExtremeXOS leverages AVB to identify and
reserve network resources for A/V trac streams and supports
synchronous streaming capabilities to ensure reliable and high-quality A/V
transmissions over Ethernet. AVB also enables time sensitive multimedia
streams to be sent over the Ethernet network with low latency and
provides service quality for high definition information and entertainment
applications.
DCB Support with Enterprise Core Class
Scalability
The Summit X670 series supports Data Center Bridging features such as
Priority Flow Control (PFC), Enhanced Transmission Selection (ETS) and
Data Center Bridging eXchange (DCBX) for data center convergence. At
