Summit X670V Series
|
The Summit® X670V-48t switches are
purpose-built top-of-rack switches designed
to support emerging 10 Gigabit Ethernetenabled
servers in enterprise and cloud data
centers. Summit X670 helps optimize new
server deployments with its optional,
future-proofing 40 GbE uplink support while
providing seamless support from existing
Gigabit Ethernet-based servers to 10
GbE-based high-performance servers to
start the transition to the new virtualized
environment.
The Summit X670V-48t provides high density for 10 Gigabit Ethernet switching in a small
1RU form factor. These switches support up to 64 10GbE ports in one system and 448 10GbE
ports in a stacked system using high-speed SummitStack-V160, which provides 160 Gbps
throughput and distributed forwarding. And, additionally, these switches support up to 384
10GbE ports of 10GbE in a stacked system using high-speed SummitStack-V320, which
provides 320 Gbps throughput and distributed forwarding.
With its versatile design, the Summit X670 provides high density Layer 2/3 switching with
low latency cut-through switching, and IPv4 and IPv6 unicast and multicast routing to
enable enterprise aggregation and core backbone deployment in AC-powered and
DC-powered environments.
Summit X670 series simplifies network operation with the ExtremeXOS® modular operating
system (OS), which is used amongst all Extreme Networks® Summit and BlackDiamond®
Ethernet switches. The high availability ExtremeXOS operating system provides simplicity
and ease of operation through the use of one OS everywhere in the network.
10 Gigabit Ethernet Switching
The Summit X670 model offers 48-port 10 Gigabit Ethernet non-blocking switching with
10GBASE-T interfaces. Summit X670 is capable of Layer 2 and Layer 3 forwarding at up to
714 million packets per second forwarding rate in a small 1RU form factor, enabling
next-generation high-performance server deployment in data centers. And the X670
supports SummitStack-V high-speed, longer distance stacking over the 10GbE ports.
SummitStack-V–Flexible Stacking Over 10
Gigabit Ethernet
SummitStack-V capability utilizes 10 GbE ports as stacking ports, enabling the use of
standard cabling and optics technologies used for 10GbE BASE-T RJ45 and BASE-X SFP+
available on the X670V-48t. SummitStack-V provides long-distance stacking connectivity of
up to 40 km while reducing the cable complexity of implementing a stacking solution.
SummitStack-V enabled 10 GbE ports must be physically direct-connected. SummitStack-V
is compatible with Summit X450e, X450a, X460, X480, X650 and X670 switches running
the same version of ExtremeXOS.
40 Gigabit Ethernet Uplinks and
High-Speed 320 and 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 952 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-efficient hardware design. The power supplies are also
highly efficient, 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 traffic to be controlled independently
based on Class of Service. PFC allows network traffic that requires lossless
throughput to be prioritized, while other traffic types that do not require or
perform better without PFC can continue as normal.
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
the same time, the Summit X670 series offers more cost-effective 10
Gigabit Ethernet switches, for both small-sized core backbone and
traditional three-tier network architectures. Summit X670 series can
support 10 Gigabit Ethernet campus aggregation with its core class routing
and switching scalability. The Summit X670 series can support up to 16,000
IPv6 longest prefix matching routing tables, 6,000 IP ARP entries and
3,000 IP multicast group entries.
One Operating System
Extreme Networks simplifies network operation by offering one common
OS – ExtremeXOS – throughout the BlackDiamond and Summit switchIng
portfolio. From 10/100 Mbps switching products such as Summit X150
and Summit X250e to the multi-10 gigabit core backbone BlackDiamond
modular chassis switches, all switches can run the same version of the OS,
which helps deploy, operate and maintain your entire network and reduce
operating costs.
10 Gigabit Ethernet Copper
The Summit X670-48t switch supports 48 10GBase-T interfaces.
10GBASE-T supports simpler cabling infrastructure, industry- standard and
commonly used unshielded twisted pair cable, and can support up to 100
meters with Category 6a or 55 meters with Category 6 or 5e cable. The
10GbE copper ports autonegotiate for 100Mbps, 1Gbps, or 10Gbps speeds.
|
10 Gigabit Ethernet SFP+
The Summit X670-48t switch supports 4 ports SFP+ optics on shared
combination ports, which can support passive copper cable for up to 10
meters. The switches also support fiber-optical cable installation with SFP+
transceivers such as 10GBASE-SR, LR, LRM, and ER. Summit X670 SFP+
ports support dual interface speeds of Gigabit Ethernet and 10 GbE. SFP+
ports can accept both gigabit SFP and 10 gigabit SFP, and depending upon
the pluggable optics you choose, SFP+ can work in both modes.
40 Gigabit Ethernet QSFP+
The Summit X670V model provides a VIM4 slot for the optional VIM4-
40G4X module. The VIM4-40G4X module supports four QSFP+ optics,
and supports up to four ports of 40 GbE. 40 GbE QSFP+ ports can accept
QSFP+ passive and active cables, as well as QSFP+ transceivers. Each
40 GbE port can be configured as a 40 GbE port or as four 10 GbE ports.
The 10 GbE port mode can be supported by a 40GBASE-SR4 QSFP+
transceiver and fan-out optical cables, and is compatible with the
10GBASE-SR optical interface for distances up to 100 meters.
Low Power Consumption with
Optimized Cooling Options
The Summit X670-48t switch consumes low power and provides optimized
cooling options. Most servers installed in a standard 19-inch rack system
flow air from front to back to maximize cooling performance. Compared to
side-to-side air flow, front-to-back air flow provides more effective cooling
throughout the rack system in the data center. The Summit X670 series has
2+1 hot swappable fan tray offering effective front-to-back air flow, or
back-to-front air flow.
Back-to-front air flow allows placement of 10 Gigabit
Ethernet SFP+ ports in the back side of the rack and reduces distance
between switches and servers for 10GBASE-CR SFP+ passive copper cable
installations.
Modular Operating System for
Non-Stop Operation
- Preemptive Multitasking and Protected Memory
Summit X670 series switches allow each of many applications—such as
Open Shortest Path First (OSPF) and Spanning Tree Protocol (STP)—to run
as separate OS processes that are protected from each other. This drives
increased system integrity and inherently protects against DoS attacks.
- Process Monitoring and Restart
ExtremeXOS increases network availability using process monitoring and
restart. Each independent OS process is monitored in real time. If a process
becomes unresponsive or stops running, it can be automatically restarted.
- Loadable Software Modules
The modular design of the ExtremeXOS OS allows the upgrading of
individual software modules, should this be necessary, leading to higher
availability in the network.
- Spanning Tree/Rapid Spanning Tree Protocols
Summit X670 supports Spanning Tree (802.1D), Per VLAN Spanning Tree
(PVST+), Rapid Spanning Tree (802.1w) and Multiple Instances of Spanning
Tree (802.1s) protocols for Layer 2 resiliency.
- Software-Enhanced Availability
Software-enhanced availability allows users to remain connected to the
network even if part of the network infrastructure is down. Summit X670
continuously checks for problems in the uplink connections using advanced
Layer 3 protocols such as OSPF, VRRP and Extreme Standby Router
Protocol™ (ESRP, supported in Layer 2 or Layer 3), and dynamically routes
traffic around the problem.
- Equal Cost Multipath
Equal Cost Multipath (ECMP) routing allows uplinks to be load balanced for
performance and cost savings while also supporting redundant failover. If
an uplink fails, traffic is automatically routed to the remaining uplinks and
connectivity is maintained.
- Link Aggregation (802.3ad)
Link aggregation allows trunking of up to eight links on a single
logical connection, for up to 80 Gbps of redundant bandwidth per
logical connection.
- Multi-Switch LAG (Ì-LAG)
M-LAG can address bandwidth limitations and improve network resiliency, in
part by routing network traffic around bottlenecks, reducing the risks of a
single point of failure, and allowing load balancing across multiple switches.
- Hardware Redundancy
Summit X670 series switches support a dual redundant AC/DC power
supply to provide high availability. The power supply can be hot-swapped
and replaced should it fail. Summit X670 also supports N+1 redundant
hot-swappable fan trays.

Robust IP and MAC Security Framework
-
Media Access Control (MAC) Lockdown
MAC security allows the lockdown of a port to a given MAC address and
limiting the number of MAC addresses on a port. This capability can be
used to dedicate ports to specific hosts or devices such as VoIP phones or
printers and avoid abuse of the port—a capability that can be especially
useful in environments such as hotels. In addition, an aging timer can be
configured for the MAC lockdown, protecting the network from the effects
of attacks using (often rapidly) changing MAC addresses.
- IP Security
ExtremeXOS IP security framework helps protect the network
infrastructure, network services such as DHCP and DNS and host
computers from spoofing and man-in-the-middle attacks. It also protects
the network from statically configured and/or spoofed IP addresses and
builds an external trusted database of MAC/IP/port bindings providing the
traffic’s source from a specific address for immediate defense.
- Identity Manager
Identity Manager allows network managers to track users who access their
network. User identity is captured based on NetLogin authentication, LLDP
discovery and Kerberos snooping. ExtremeXOS uses the information to
then report on the MAC, VLAN, computer hostname, and port location of
the user. Further, Identity Manager can create both roles and policies,
and then bind them together to create role-based profiles based on
organizational structure or other logical groupings, and apply them across
multiple users to allow appropriate access to network resources. In
addition, support for Wide Key ACLs further improves security by going
beyond the typical source/destination and MAC address as identification
criteria access mechanism to provide filtering capabilities.
Threat Detection and Response
- CLEAR-Flow Security Rules Engine
CLEAR-Flow Security Rules Engine provides first-order threat detection
and mitigation, and mirrors traffic to security appliances for further analysis
of suspicious traffic in the network.
- sFlow
Summit X670 series supports hardware-based sFlow® sampling that
provides the ability to sample application-level traffic flows on all
interfaces simultaneously.
- Port Mirroring
To allow threat detection and prevention, Summit X670 supports
many-to-one and one-to-many port mirroring. This allows the mirroring
of traffic to an external network appliance such as an intrusion detection
device for trend analysis or for utilization by a network administrator for
diagnostic purposes. Port mirroring can also be enabled across switches in
a stack.
- Line-Rate Ingress and Egress ACLs
ACLs are one of the most powerful components used in controlling
network resource utilization as well as in protecting the network.
Summit X670 series supports up to 2,048 ingress ACLs and 1,024 egress
ACLs per system based on Layer 2-, 3- or 4-header information such as the
MAC or IP source/destination address. ACLs are used for filtering the traffic,
as well as classifying the traffic flow to control bandwidth, priority,
mirroring, and policy-based routing/switching.
- Denial of Service Protection
Summit X670 series effectively handles Denial of Service (DoS) attacks. If
the switch detects an unusually large number of packets in the CPU input
queue, it assembles ACLs that automatically stop these packets from
reaching the CPU. After a period of time these ACLs are removed, and
reinstalled if the attack continues. ASIC-based LPM routing eliminates the
need for control plane software to learn new flows, allowing more network
resilience against DoS attacks.
- Secure and Comprehensive Network Management
As the network becomes a foundation of the enterprise application,
network management becomes an important piece of the solution.
Summit X670 supports comprehensive network management through
Command Line Interface (CLI), SNMP v1, v2c, v3, and ExtremeXOS
ScreenPlay™ embedded XML-based Web user interface. With a variety of
management options and consistency across other Extreme Networks
modular and stackable switches, Summit X670 series switches provide
ease of management for demanding converged applications.
Extreme Networks has developed tools that simplify and help in efficiently
managing your network. Ridgeline network and service management
provides fault, configuration, accounting, performance and security
functions, allowing more effective management of Extreme Networks
products, solutions and third-party devices in a converged network.
