DESCRIPTION

Using or looking at Hyper-V for your workloads? Learn how the Cisco Nexus 1000V virtual access/distributed switch can help simplify your Hyper-V virtual environment through a non-disruptive operational model, policy based provisioning, and a strong services ecosystem. You will learn about the Cisco Nexus 1000V architecture, how it integrates with Microsoft's System Center Virtual Machine Manager (SCVMM) and the rich networking capabilities it brings to Hyper-V environments. Integrated into the Windows Server 2012 Extensible Switch, and fully compatible with System Center Virtual Machine Manager 2012 SP1, the Cisco® Nexus 1000V Series provides: Advanced virtual machine networking based on Cisco NX-OS operating system and IEEE 802.1Q switching technology Cisco vPath technology for efficient and optimized integration of virtual network services Tight integration with System Center Virtual Machine Manager 2012 SP1 Layer 2 Switching with Transmit side Rate Limiting Security Policy Mobility, inbuilt support for Private VLANs with local PVLAN Enforcement Provisioning Port Profiles with deep Integration with SCVMM Traffic Visibility, including VM Migration Tracking, NetFlow v.9 with NDE, Cisco Discovery Protocol v.2 And so much more ON-DEMAND RECORDING HERE : https://cisco.webex.com/ciscosales/lsr.php?AT=pb&SP=EC&rID=66514357&rKey=7b25fe3bee5c4796 ACCESS TO THE ON-LINE NEXUS 1000V COMMUNITY : https://communities.cisco.com/community/technology/datacenter/nexus1000v

What is the pricing associated with Nexus 1000V for Hyper-V?Ans: It will be consistent with the existing product. Does the product work with all vesions of Hyper-V?Ans: the product works only with Hyper-V 3.0 that version that is shippedwith WS2012. Also, you need to have SCVMM 2012 to use N1KV. Can the same N1KV manage both ESX & Hyper-V?Ans: No. Sepearate N1KV switches should be deployed for different hypervisorenvironments. 2010 Cisco and/or its affiliates. All rights reserved.
