Summit X650 Series
High-Performance Switching and Routing
Summit X650 offers intelligent switching and routing with exceptional high-performance stacking technology for next
generation enterprise data centers—as well as dedicated 10 Gigabit Ethernet uplink capabilities powered by the
ExtremeXOS modular OS. With its low packet forwarding latency, Summit X650 helps enhance the data center and the
HPCC environment.
for 10 GbE such as XFP, SFP+, 10GBASE-T and XENPAK.
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/X670V
switches running the same version of ExtremeXOS.
SummitStack-V80, V160, & V320 –
Flexible Stacking Over 40 Gigabit
Ethernet
SummitStack-V80, V160, & V320 capability utilizes 40 GbE ports
as stacking ports, enabling the use of standard cabling and optics
technologies used for 40 GbE such as QSFP+. SummitStack- V80,
V160, & V320 enabled 40 GbE ports must be physically direct-
connected. SummitStack- V80, V160, & V320 is compatible with
Summit X460, X480, X650 and X670/X670V switches running the
same version of ExtremeXOS.
Dedicated Uplinks at 160 Gbps
Summit X650 can support 4 ports of 40 Gigabit Ethernet by
installing the optional VIM3-40G4X. These ports can be used 40
GbE data ports or broken out into 4 ports each of 10 GbE using a
QSFP+ to SFP+ breakout cable. These ports can also be used for
SummitStack V80, V160, or V320.
Summit X650 can also support an additional 8-ports of 10 Gigabit
Ethernet by installing the optional VIM-10G8X module which offers
8-port 10 Gigabit Ethernet SFP+ ports as well as SummitStack
40G ports. With this option, you can maximize the number of
interfaces for servers up to 24 ports while using the dedicated
8-port 10 Gigabit Ethernet for uplink connectivity. The optional
VIM1-10G8X provides ideal bandwidth to the backbone by offering
80 Gbps aggregated bandwidth. With this 8-port 10 Gigabit
Ethernet SFP+ module, Summit X650 can support up to 32 ports
of 10 Gigabit Ethernet in a 1RU form factor. This option provides 3:1
oversubscription from front ports (total 24 ports) to uplink ports
(total 8 ports) and maximizes server port density.
10 Gigabit Ethernet Switching
Summit X650 offers 24-port 10 Gigabit Ethernet non-blocking
switching with IEEE 802.3an standard-based 10GBASE-T interfaces or
10GBASE-X SFP+ interfaces. Summit X650 is capable of Layer 2 and
Layer 3 forwarding at 363 million packets per second forwarding rate
in a small 1RU form factor, enabling the next generation high-
performance server deployment in
data centers.
With its flexible architecture provided by the Versatile Interface
Modules (VIMs), you can configure Summit X650 to best suit your
network needs (see Figure 1).
SummitStack Support
Summit X650 supports compatible SummitStack solutions
available in the popular Summit X250e, X450e, X450a, X460 and
X480 series switches. Support for SummitStack offers a great
migration path from gigabit-enabled servers to high-performance
10 gigabit-enabled servers. You can configure two SummitStack
40G stacking ports to provide ease of management for gigabit and
10 gigabit mixed stacking. SummitStack is provided through the
standard VIM1-SummitStack module installed by default.
10 Gigabit Optimized Stacking
Support
For higher density 10 Gigabit Ethernet requirements now or
in the future, Summit X650 provides a 10 gigabit optimized
stacking solution. Summit X650 offers an optional
SummitStack256 module which provides up to 256 Gbps full
duplex stacking bandwidth. With the SummitStack256 solution,
Summit X650 can provide 256 Gbps stacking bandwidth
optimized for high-density 10 Gigabit Ethernet switching and
provides up to 192 10 Gigabit Ethernet ports with only 8RU of
height in a fully redundant configuration. Summit X650 also offers
an optional 48-port 10 Gigabit Ethernet non-blocking configuration
by stacking two Summit X650 switches together with an optional
VIM1-SummitStack512 module.
