Product Overview

The Cisco Nexus ® 1100 Series Virtual Services Appliances (VSAs) offer dedicated hardware platforms for the deployment of network services critical to virtualized data center infrastructure (Figure 1). The appliances host a number of virtual service blades (VSBs), including the following: the Cisco Nexus 1000V Virtual Supervisor Module (VSM), the Cisco Virtual Security Gateway (VSG), the Cisco Prime Network Analysis Module (NAM), and the Cisco Data Center Network Manager (DCNM) for both LAN and SAN management. These VSBs provide a comprehensive solution for virtual networking services in the data center. Dedicated hardware for the Cisco Nexus 1000V VSM eases virtual access switch deployment for the network administrator, and with its support for additional VSBs, the Cisco Nexus 1100 Series VSAs are crucial components of a virtualized data center.

Cisco Nexus 1000V Series Switches

Cisco Nexus 1000V Series Switches are intelligent virtual machine access switches designed for hypervisor environments. Operating inside a hypervisor, the Cisco Nexus 1000V Series supports server virtualization technology to provide:

• Policy-based virtual machine connectivity

• Mobile virtual machine security and network policy

• Nondisruptive operation model for your server virtualization and networking teams

Server virtualization usually changes the deployment and management of server operating systems, leading to longer deployment times, with a greater degree of coordination among server, network, storage, and security administrators. The Cisco Nexus 1000V Series offers a consistent networking feature set and provisioning process all the way from the virtual machine access layer to the core of the data center network infrastructure. Virtual servers can use the same network configuration, security policy, diagnostic tools, and operation models as their physical server counterparts attached to dedicated physical network ports. Virtualization administrators can access predefined network policies that follow mobile virtual machines to help ensure proper connectivity, saving valuable time that administrators can use to focus on virtual machine administration. This comprehensive set of capabilities helps you deploy server virtualization faster and achieve its benefits sooner (Figure 2).

Product Architecture

The Cisco Nexus 1100 Series VSAs offer dedicated hardware for the Cisco Nexus 1000V VSM and other virtual network services. Network administrators can install and configure virtual access switches similar to the way they install and configure physical switches. Dedicated VSM hardware is especially helpful during data center power up, because there is no dependency in finding server resources for the VSM. Thus, the Cisco Nexus 1100 Series VSAs allow network administrators to manage the Cisco Nexus 1000V Series virtual access switch like physical switches and scale server virtualization deployments (Figure 3).

Figure 3. Cisco Nexus 1100 Series Architecture

Figure 4 shows the internal architecture of the Cisco Nexus 1100 Series. The Cisco Nexus VSA Manager, based on the Cisco ® NX-OS Software, manages VSBs, installation, and blade configuration. The Cisco Nexus VSA Manager offers a familiar Cisco NX-OS interface for network administrators installing and configuring VSBs. The Cisco Nexus VSA Manager also supports Cisco NX-OS high availability, allowing a standby Cisco Nexus 1100 Series VSA to become active if the primary Cisco Nexus 1100 Series VSA fails.

Figure 4. Cisco Nexus 1100 Series Internal Architecture

Cisco Nexus 1100 Series High Availability (HA)

Cisco Nexus 1100 Series VSAs offer high-availability features for large-scale networking. Within a single appliance, a Cisco Nexus 1100 Series VSA offers process-level availability conferred by the modular nature of Cisco NX-OS, as well as VSB availability features such as restart-on-failure. Cisco Nexus 1000V VSM active-standby high availability is fully supported on the Cisco Nexus 1100 Series. With dual Cisco Nexus 1100 Series VSAs deployed in a high-availability cluster, active-standby failover of Cisco Nexus VSA Manager and VSBs is also supported.

VSM on Cisco Nexus 1100 Series VSA Compared to VSM as a Virtual Machine

Table 1 compares deployment of a Cisco Nexus 1000V VSM as a virtual machine and on the Cisco Nexus 1100 Series. For customers who want a complete software deployment of the Cisco Nexus 1000V Series, deployment of the VSM as a virtual machine provides flexibility in VSM placement and even mobility with VMware vMotion. However, for network administrators who want greater control over the management of the VSM, the Cisco Nexus 1100 Series provides a complete Cisco NX-OS experience while installing the Cisco Nexus 1000V Series virtual access switch. In addition, the Cisco Nexus 1100 Series offers fewer dependencies when the data center is powered on because the VSM can be initiated at the same time as the Cisco Nexus 1000V Virtual Ethernet Modules (VEMs).
