The Cisco VSG has the following requirements:
- Microsoft SCVMM R2
- Virtual Machine (VM)
- 64-bit VM is required.
- x86 Intel or AMD server with a 64-bit processor.
- 2 GB RAM, recommended space is 4 GB RAM.
- 3 NICs.
- Minimum 3 GB hard disk space with LSI Logic Parallel adapter (default), recommended space is 4 GB hard disk.
- Minimum CPU speed of 1.5 GHz.
Cisco VSG and Supported Cisco Nexus 1000V Series Device Terminology
This table lists the terminology used in the Cisco VSG implementation.
Term |
Description |
---|---|
Logical Switch |
Logical switch that spans one or more servers. It is controlled by one VSM instance. |
NIC |
Network interface card. |
Server hosting SCVMM |
Service that acts as a central administrator for Microsoft Hyper-V hosts that are connected on a network. The server directs actions on the VMs and the VM hosts. |
Virtual Ethernet Module (VEM) |
Part of the Cisco Nexus 1000V Series switch that switches data traffic. It runs on a Microsoft Hyper-V host. Up to 64 VEMs are controlled by one VSM. All the VEMs that form a switch domain should be in the same virtual data center as defined by the Hyper-V server. |
Virtual Machine (VM) |
Virtualized x86 PC environment in which a guest operating system and associated application software can run. Multiple VMs can operate on the same host system concurrently. |
vPath |
Component in the Cisco Nexus 1000V Series switch with a VEM that directs the appropriate traffic to the Cisco VSG for policy evaluation. It also acts as fast path and can short circuit part of the traffic without sending it to the Cisco VSG. |
Virtual Security Gateway (VSG) |
Cisco software that secures virtual networks and provides firewall functions in virtual environments using the Cisco Nexus 1000V Series switch by providing network segmentation. |
Virtual Supervisor Module (VSM) |
Control software for the Cisco Nexus 1000V Series distributed virtual device that runs on a Virtual Machine (VM) and is based on Cisco NX-OS. |
SCVMM |
System Center Virtual Machine Manager Connect remotely to Hyper-V server. It is the primary interface for creating, managing, and monitoring VMs, their resources, and their hosts. It also provides console access to VMs. |
