Features And Specifications - Lenovo Flex System Fabric CN4093 Product Manual

CN4093 hybrid stacking capabilities simplify management for clients by stacking up to eight switches
(two CN4093 and from two to six EN4093/EN4093R switches) that share one IP address and one
management interface. Support for Switch Partition (SPAR) allows clients to virtualize the switch with
partitions that isolate communications for multi-tenancy environments.
Transparent networking capability
With a simple configuration change to "easy connect" mode, the CN4093 becomes a transparent
network device, invisible to the core, eliminating network administration concerns of Spanning Tree
Protocol configuration/interoperability, VLAN assignments and avoidance of possible loops.
By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by eliminating
the need to configure the typical access switch parameters.
Integrate network management
A key challenge is the management of a discrete network environment. The CN4093 supports a
command-line interface (CLI) for integration into existing scripting and automation. Network
management can be simplified by using port profiles, topology views, and virtualization management.
System Center is used for more advanced levels of management and control, which can significantly
reduce deployment and day-to-day maintenance times, while providing in-depth visibility into the
network performance and operations of Lenovo switches. Furthermore, when leveraging tools like
VMware vCenter Server or vSphere, Switch Center provides additional integration for better
optimization.

Features and specifications

The Flex System Fabric CN4093 10Gb Converged Scalable Switch has the following features and
specifications:
Internal ports
Forty-two internal full-duplex 10 Gigabit ports
Two internal full-duplex 1 GbE ports connected to the Chassis Management Module
External ports
Two ports for 1 Gb or 10 Gb Ethernet SFP/SFP+ transceivers (support for 1000BASE-SX,
1000BASE-LX, 1000BASE-T, 10GBASE-SR, 10GBASE-LR, or SFP+ direct-attach copper (DAC)
cables. SFP+ modules and DAC cables are not included and must be purchased separately.
Twelve Omni Ports, each of which can operate as a 10 Gb Ethernet (support for 10GBASE-SR,
10GBASE-LR, or 10 GbE SFP+ DAC cables), or auto-negotiating 4/8 Gb Fibre Channel,
depending on the SFP+ transceiver installed in the port. SFP+ modules and DAC cables are
not included and must be purchased separately.
Note: Omni Ports do not support 1 Gb SFP Ethernet transceivers.
Two ports for 40 Gb Ethernet QSFP+ transceivers or QSFP+ DAC cables. In addition, you can
use break-out cables to break out each 40 GbE port into four 10 GbE SFP+ connections.
QSFP+ modules and DAC cables are not included and must be purchased separately.
One RS-232 serial port (mini-USB connector) that provides an additional means to configure
the switch module.
