Cisco SRE-V Overview

Cisco SRE-V is a branch-office infrastructure platform that combines computing, networking, storage access, virtualization, and unified management into a cohesive system. It enables the VMware vSphere HypervisorTM to be provisioned on a Cisco Services Ready Engine (SRE) Service Module and host one or multiple virtual machines running the Microsoft Windows Server operating system. The entire system is integrated with the Generation 2 of the Cisco Integrated Services Router (ISR G2).

Figure 1-1 provides an example of a Cisco SRE-V system deployment.

Cisco SRE-V Terms

The following Cisco SRE-V terms are used in this guide:

Cisco SRE Service Module—Intel x86 architecture blade server that is hosted in a Cisco ISR G2. The Cisco SRE Service module provides the dedicated processing, network, storage, and memory to run the VMware vSphere HypervisorTM.

VMware vSphere HypervisorTM—Bare-metal hypervisor from VMware that provides the platform to host virtual machines.

Console Manager—Embedded virtual machine running Cisco Linux that provides console access to the VMware vSphere HypervisorTM for functionality that is specific to Cisco.

Microsoft Windows Virtual Machine—User-created virtual machine that runs the Microsoft Windows Server operating system.

See Figure 1-2 to understand the Cisco SRE-V terms.

Figure 1-2 Cisco SRE-V Terms

Difference Between Cisco SRE-V and VMware vSphere Hypervisor

The Cisco SRE-V product is different from the VMware vSphere HypervisorTM in the following ways:

Cisco SRE-V enables VMware vSphere HypervisorTM to be provisioned on a Cisco SRE Service Module, which is integrated in the Cisco ISR G2.

Configuration of the VMware vSphere HypervisorTM IP address is done through the Cisco ISR G2.

Configuration of the user management tasks is done using the Cisco SRE-V CLI instead of the VMware vSphere Client.

License management for Cisco SRE-V is done through Cisco Software Licensing (CSL).

Software upgrade packages for Cisco SRE-V are obtained from Cisco.com. Software upgrades are done using the Cisco SRE-V CLI.

System operation such as firmware settings, advanced settings, and PCI PassThru settings are disabled.

vCenter server access support is not available in Cisco SRE-V.

Hardware Requirements

The Cisco SRE-V software runs on the Cisco SRE Service Module, which is the hardware component of Cisco SRE-V. The Cisco SRE Service Module can reside either in the Cisco 2900 series or 3900 series ISR G2.

The Cisco SRE-V software is supported on the following service modules:

Cisco SRE 700 Service Module

Cisco SRE 900 Service Module

Table 1-1 provides the hardware information for each of the supported service modules.

Software Requirements

This section provides information about third-party software, Cisco SRE-V options, and feature licenses.

Third-Party Software

Cisco SRE-V uses the following third-party software:

VMware vSphere HypervisorTM—For virtualization.

Microsoft Windows Server—For the operating system.

The following Microsoft Windows Servers are certified:

Windows Server 2003 SP2 Standard 32-bit and 64-bit

Windows Server 2003 SP2 Enterprise 32-bit and 64-bit

Windows Server 2008 R2 Standard 64-bit

Windows Server 2008 R2 Enterprise 64-bit

Cisco SRE-V Options

Cisco SRE-V is available in the following three options:

Hardware only (SM-SRE-700-K9 or SM-SRE-900-K9)Cisco SRE Service Module without any software installed on it. See Option 1 in Figure 1-3.

If you purchase this option, you must download and install Cisco SRE-V software as well as your own version of the Microsoft Windows Server 2003 or Microsoft Windows Server 2008 software.

Hardware plus Virtualization software (SM-SRE-700-K9 or SM-SRE-900-K9 + SW-SM-SRE-V-1.0-K9)—Cisco SRE Service Module with Cisco SRE-V software preinstalled. See Option 2 in Figure 1-3.

Purchase this option if you have your own version of Microsoft Windows Server 2003 or
Microsoft Windows Server 2008 software that you want to use. If you purchase this option, the Cisco SRE-V license is preactivated.

Hardware, plus Virtualization software, plus Microsoft Windows software (SM-SRE-700-K9 or SM-SRE-900-K9 + SW-SM-SRE-V-1.0 + MSWS-08R2ST-X86-K9)—Cisco SRE Service Module with both Cisco SRE-V and Microsoft Windows Server 2008 R2 Standard Edition 64-bit virtual machine preinstalled. See Option 3 in Figure 1-3.

If you purchase this option, both the Microsoft Windows Server 2008 R2 license and the
Cisco SRE-V license are preactivated.

Figure 1-3 shows the Cisco SRE-V options.

Feature Licenses

Table 1-3 provides the feature licenses that are available for Cisco SRE-V.

Table 1-3 License SKUs 

License SKUs
Description

FL-SRE-V-HOST

VMware vSphere Hypervisor Host pre-activated paper license purchased with the software.

FL-SRE-V-HOST=

VMware vSphere Hypervisor Host paper license purchased without the software (spare). You must activate this license.

L-FL-SRE-V-HOST=

VMware vSphere Hypervisor Host electronic license purchased without the software (spare). You must activate this license.


For information about Cisco SRE-V software licenses, see Chapter 5, "Managing the Cisco SRE-V Software Licenses."

Managing Cisco SRE-V

Cisco SRE-V uses several management interfaces:

Cisco IOS CLI

Use the Cisco IOS CLI to configure the host router and Cisco SRE Service Module interfaces. Cisco SRE-V resides on a Cisco SRE Service Module, which fits into a host Cisco router that runs the Cisco IOS software. For information about the supported Cisco IOS software, see the "Verifying the Router, Cisco SRE Service Module, and Cisco IOS Software Version Compatibility" section on page 2-2.

Cisco SRE-V CLI

Use the Cisco SRE-V CLI to configure users and assign those users with permissions to host and manage virtual machines. You can also use the Cisco SRE-V CLI to manage licenses and software upgrades. Cisco SRE-V has a virtual machine management engine with its own startup and run-time configurations and its own CLI, all of which are independent of the Cisco IOS configuration on the router.


Note Instead of the Cisco SRE-V CLI, you can use the Cisco License Manager to automate license-related work flow. See the "Cisco License Manager" section.


Cisco License Manager

Use the Cisco License Manager to automate all license-related work flow. Cisco License Manager securely communicates with the licensing back-end fulfillment systems at Cisco.com and deploys obtained licenses to managed devices on a network-wide basis. Cisco License Manager is available at no cost and can be downloaded by registered Cisco.com users from http://www.cisco.com/go/clm.

VMware vSphere Client

Use the VMware vSphere Client to manage virtual machines.

Basic Workflow

1. Install the Cisco SRE Service Module into the ISR G2.

2. Use the Cisco IOS commands to configure the Cisco SRE Service Module interfaces.

3. If you purchase a blank Cisco SRE Service Module, install the Cisco SRE-V software, and then activate the software license.

4. Use the Cisco SRE-V commands to create users and roles, and then assign permissions to those users.

5. Configure the VMware vSphere HypervisorTM default gateway.

6. Install the vSphere Client, and then use the vSphere Client GUI to create and manage the virtual machines.

7. Use the vSphere Client to create additional virtual machines.
