Cisco Nexus 4001I Switch Module

• Lower Total Cost of Operation, High Performance, Enhanced Server Virtualization, and Increased Resilience

The Cisco Nexus™ 4001I Switch Module for Bull Blade Series is a blade switch solution for Bull Blade Chassis - Enterprise, providing the server I/O solution required for high-performance, scale-out, virtualized and nonvirtualized x86 computing architectures. It is a line-rate, extremely low-latency, nonblocking, Layer 2, 10 Gigabit Ethernet blade switch that is fully compliant with the INCITS Fibre Channel over Ethernet (FCoE) and IEEE 802.1 Data Center Bridging (DCB) standards.

End-to-end 10Gb switch offers a high-performance, low-latency solution that seamlessly integrates with other Cisco® Nexus family products.

Optional upgrade license key enables easy transition to FCoE.

20 ports of 10Gb (14 internal and 6 external) bandwidth.

Supported on Bull Blade Châssis - Enterprise and compatible with Open Fabric Manager.

Common Nexus CLI and web based management tool.


	At the center of the Cisco Nexus 4001I is the unified switch application-specific integrated circuit (ASIC), a new, purpose-built, high-performance, line-rate switch ASIC that delivers extremely low and consistent latency across all packet sizes independent of the configured networking features. The unified switch ASIC supports standard Ethernet as well as Priority Flow Control (PFC) and Enhanced Transmission Selection, required for lossless Ethernet transmission. LAN and SAN networking protocols are delivered through Cisco® NX-OS Software, the industry’s first modular, fault-tolerant, highly available operating system designed specifically to support unified fabric data center networks. Using the combination of the unified switch ASIC and Cisco NX-OS, the Cisco Nexus 4001I extends the benefits of the Cisco Nexus Family of data center switches to blade servers: the fastest growing segment of the server market.
Lower total cost of operation (TCO):
	Deployment of unified fabric with the Cisco Nexus 4001I at the blade server access enables a significant reduction in the number of switches, LAN and SAN network interface cards (NICs), ports, optic modules, and cables. This consolidation of server access network elements significantly reduces the overall capital and operation costs of the data center network through reduction in the number of network elements that need to be purchased, managed, powered, and cooled.
High performance:
	The Cisco Nexus 4001I is a line-rate, feature-rich, extremely low-latency switch capable of enabling server access migration from Gigabit Ethernet to 10 Gigabit Ethernet to lossless 10 Gigabit Ethernet, as well as supporting the demanding latency requirements of high-frequency trading applications.
Enhanced server virtualization:
	Using unified fabric at the server access with Cisco Nexus 4001I provides the uniform interfaces, simplified cabling, and consistent server access design required to gain the advantages of automated virtual machine mobility. The Cisco Nexus 4001I used in conjunction with the Cisco Nexus 1000V Switch delivers an operationally consistent and transparent server access design for virtual machine deployments, substantially reducing the overhead needed to configure, troubleshoot, and repair the server access link between the virtual NIC (vNIC), virtual switch, and the blade switch.
Increased resilience:
	The Cisco Nexus 4001I extends Cisco NX-OS to the blade server access, providing a fault-tolerant network with single modular operating system across the data center.
