Designing Service Networks—Basic Workflow

Table 13-1 is an overview of the steps you take to design a service network in VFrame.

Table 13-1 Designing Service Networks—Basic Workflow 

 
Task

Step 1 

Create a service network (see Creating and Modifying Service Networks).

As part of this task and depending on your service network design, define the following element and endpoint parameters, as required:

Block variables (see Defining Block Variable Values).

Variable values (see Defining Port Variable Values).

Resource pools (see Assigning Resource Pools).

Server groups (see Defining Server Groups).

Step 2 

Save your service network design (see Saving Service Networks).


Understanding Service Network Design

You create service networks based on service network templates. The template identifies generic information, and the service network identifies the actual resources (resource pools, variable values, server configuration, and so on) that are required to start and operate your service network.

In some service network designs, there are special considerations pertaining to network virtualization.

The following topics help you understand key concepts to help you design your service network:

Understanding Service Network Design Elements

Changing Service Networks

Understanding Service Network Design Elements

Before designing your service network, it is helpful to understand these service network design elements:

Block Variables—Most logical elements have system actions or macros associated with them, and these system actions or macros have variables. You must supply the values for these variables. The values are substituted for the variables in the system actions or macros at run time.

An example of a block variable is the VLAN variable required for defining a Layer 2 Switch in a service network.

Pool Selection— All logical elements, except Layer 2 switches, require that you select the resource or resource pool to use when the service network is deployed. When you deploy your service network, resources are acquired based on the resource or resource pool you have selected. For more details about resource pools, see Resource Pool Overview, page 9-2.

Server Group Definition—In order for VFrame to create and image the servers in your service network, you must define the server group parameter values, such as the storage type, location, and golden image. This information is used to create, image, and start your servers when you deploy your service network.

Changing Service Networks

After you define and deploy a service network, you can add and remove resources and resource pools. However, the change does not take effect until the next time the service network tries to acquire a resource from the assigned resources or resource pools.

You can change certain variable values in a service network while the network is running. The variable values you can change are those to which VFrame does not attach any specific meanings or relationships, for example, strings, numbers, or Boolean values. These are called primitive variables.

Another variable type, called resource variables, can also be changed; however, changes do not take effect until the next time the service network attempts to acquire resources. Resource variables are those that require a resource, such as an IP address, VLAN, or storage resource (LUN or Qtree).

Designing a Service Network—Scenario

This scenario builds upon the service network template you created in Chapter 11, "Designing Templates." The template is based on a sample network design in which you have a switch with a CSM connected in single subnet (bridge) mode to a group of servers, as shown in Figure 11-11.

This scenario assumes that the VFrame administrator has already completed all of the prerequisites for creating a service network template and created the CSM service network template. For details on these prerequisites, see Creating a Service Network Template—Scenario, page 11-42.

This scenario shows you how to:

Create the Service Network

Define Variable Values for the Layer 3 Switch and Its Port

Define Variable Values for the Layer 2 Switch and Its Ports

Define Variable Values for the Load Balancer and Its Ports

Define the Server Group

Verify Your Service Network Definitions

Create the Service Network

You create service networks based on service network templates. The template identifies generic information, and the service network identifies the actual resources (resource pools, variable values, server configuration, and so on) that are required to deploy your service network.

In this scenario, you create a service network called CSM-Network from the template called CSM-Template.

Procedure


Step 1 Select Design > Service Networks.

Step 2 Select the template, CSM-Template, and click New. The Input dialog box opens.

Step 3 Enter the service network name in Network name field. In this case, enter CSM-Network.

The service network opens, and its name appears in the Service Networks selector, in the Opened Service Network selector (specified by the service network name), and in a tab above the work area.


Define Variable Values for the Layer 3 Switch and Its Port

Whenever you include a logical element in your service network template, default macros, called system actions, are included as well. These system actions have their own set of default variables. For a complete list of system actions and default variables by logical element, see "System Actions, Default Variables, and Resource Attribute Variables."

In addition to these, there might be additional variables that have been included in the user macros added to the template.

In either case, you need to assign values to these variables so that when you start your network, VFrame can acquire the resources and values you need.

Procedure


Step 1 Select Design > Service Networks.

Step 2 Open the network you just created if it is not already open.

Step 3 Select the Layer 3 switch. The Pool Selection tab opens.

Step 4 Select the check box next to the Layer 3 switch or range of Layer 3 switches you need. In this case, select AdminContext: All Cisco Catalyst 6500(Layer 3 Enabled). (This is a resource pool of Layer 3 switches. VFrame automatically picks from the list of available and unused Layer 3 switches.)

Step 5 Select the To_LoadBalancer port from the Open Service Networks selector. The Port Variables tab opens containing a list of variables required for the port. Enter values in the following fields:

SviVlanGroup > Vlan—No entry is required because this variable is aliased to the LoadBalancer > CSM_container_dflt_grp > ClientVlanID variable.

SviIpAddressGroup > IPAddress—No entry is required because this variable is aliased to the LoadBalancer > ClientVlanGtw > IPAddress variable.

HelperAddressGroup > HelperAddr—10.11.2.10.

Step 6 Click Save.


Define Variable Values for the Layer 2 Switch and Its Ports

Similar to Layer 3 switches, when you include Layer 2 switches in your network design, system actions and default variables are included as well. For a complete list of system actions and default variables by logical element, see "System Actions, Default Variables, and Resource Attribute Variables."

In addition to these, there might be additional variables that have been included in the user macros added to the template.

In either case, you need to assign values to these variables so that when you start your network, VFrame can acquire the resources and values you need.

In this scenario, the only variable value required is VLAN and this variable is aliased to another variable. When you enter the value for that variable, the value for the Layer 2 VLAN variable will automatically be entered.

Define Variable Values for the Load Balancer and Its Ports

You need to provide values for variables and assign resource pools to the load balancer. The values for the load balancer ports connected to the Layer 2 and Layer 3 switches are derived from variable aliases, so you do not need to enter values for these.

Procedure


Step 1 Select Design > Service Networks.

Step 2 Open the network you just created if it is not already open.

Step 3 Select the load balancer. The Block Variables tab opens containing a list of variables required for the load balancer. Enter values in the following fields:

ClientVlanIP > IPAddress (Primary)—10.100.11.2

ClientVlanGtw > IPAddress (Primary)—10.100.11.1

ServerVlanIP > IPAddress—No entry required, because this variable is aliased to the LoadBalancer > ClientVlanIP > IPAddress variable.

RealServerIP > IPAddress (Primary)—10.100.11.1-10.100.11.254 (resource pool)

VServerIP > IPAddress—10.100.11.3

CSM_container_dflt_grp

ClientVlanID (Primary)—AdminContext: All VLAN (VFrame Created) (This is a resource pool of VLANs. VFrame automatically picks from the list of available and unused VLANs.)

ServerVlanID (Primary)—AdminContext: All VLAN (VFrame Created) (This is a resource pool of VLANs. VFrame automatically picks from the list of available and unused VLANs.)

ClientVlanType (Primary)—client

ServerVlanType (Primary)—server

VServerName—VS1

ServerFarmName—SF1

RealServerWeight—8

Step 4 Click the Pool Selection tab and select the check box next to the load balancer or pool of load balancers you need. In this case, select AdminContext: All Content Service Module. (This is a resource pool of load balancers. VFrame automatically picks from the list of available and unused load balancers.)

Step 5 Click Save.


Define the Server Group

Similar to Layer 3 and Layer 2 switches, when you include server groups in your network design, system actions and default variables are included as well. For a complete list of system actions and default variables by logical element, see "System Actions, Default Variables, and Resource Attribute Variables."

In addition to these, there might be additional variables that have been included in the user macros added to the template.

In either case, you need to assign values to these variables so that when you start your network, VFrame can acquire the resources and values you need.

You need to assign variables and resource pools to the server group and values to the server group port connected to the Layer 2 switch. In addition, you need to configure the server group definition, which configures server group properties, such as the golden image name, network interface (DHCP or Teaming), storage (NAS or SAN), sysprep, and swap size.

Procedure


Step 1 Select Design > Service Networks.

Step 2 Open the network you just created if it is not already open.

Step 3 Select the server group. The Block Variables tab opens containing fields for the variables needed for this logical element.

Step 4 Enter the appropriate values for these variables, as follows:

HostName > HostName—test

DefaultGateway

GatewayIPAddress—No entry is required because this variable is aliased to the LoadBalancer > ClientVlanGtw > IPAddress variable.

GatewayMetric—10

Step 5 Click the Pool Selection tab.

Step 6 Select the check box next to the server group or pool of server groups you need. For example, select AdminContext: All Server.

Step 7 Click the Server Group Definition tab.

Step 8 Click Configure... to open the Server Group Configuration Wizard.

Step 9 Click Next to open the next dialog box.

Step 10 In the Golden Image Selection dialog box (see Golden Image Selection Dialog Box), do the following:

a. Select the golden image to be used to image servers. For example, webserver_nas.

b. Indicate the boot image type: NAS or SAN. Boot image is based on whether the golden image is block based or file based. File-based boot images are typically NAS, and block-based boot images are typically SAN. For this scenario, select NAS.

c. Click Next to open the next dialog box.

Step 11 In the Fabric and SAN Storage Selection dialog box (see Fabric and SAN Storage Selection Dialog Box), do the following:

a. Specify the type of fabric connectivity used. Valid values are No Fabric, Single Fabric, and Dual Fabric. Fabric mode is optional for NAS networks. For this scenario, select No Fabric.

b. Click Next to open the next dialog box.

Step 12 In the NAS Storage Selection dialog box (see NAS Storage Selection Dialog Box), do the following:

a. Specify the root NFS storage pool where server images will be stored. If necessary, you can create additional storage partitions by clicking the Add button and specifying the partition name, size, and NFS volume. For this scenario, select AdminContext: All Server.

b. Click Next to open the next dialog box.

Step 13 In the Additional Logical Server Routing Configuration dialog box (see Additional Logical Server Routing Configuration Dialog Box), do the following:

a. If the default route specified under the Block Variables tab is sufficient, click Next and go to Step 14. Otherwise, configure additional routes for the server group by clicking Add and specifying the network address, netmask, gateway, and metric. In this case, the default route is sufficient.

b. Click Next to open the next dialog box.

Step 14 In the Interface Properties for Link To_Layer2Switch dialog box (see Interface Properties for Link To_Layer2Switch Dialog Box), do the following:

a. Select the number and speed of Ethernet links. For example, select One as the number of Ethernet links and Speed100Mbps as the interface speed.

b. If there are multiple interfaces, one interface must be marked as the VFrame communication interface by selecting the PXE Boot Interface check box. For this scenario, select the check box to designate this interface as the VFrame communication interface.

c. Select the Requires Port Fast on Switch Port check box if spanning tree PortFast should be configured on the switch ports attached to the deployed servers. If you select this check box, the following two commands are applied to the access switch ports:

spanning-tree portfast

spanning-tree bpduguard enable

For this scenario, select this check box.

d. Click Next to open the next dialog box.

Step 15 Review the information in the Configuration Summary dialog box, and click Finish.

Step 16 Click Save.


Verify Your Service Network Definitions

After you have defined all of the variables values, resource pools, and server group information for your service network, you need to verify that your selections are correct.

Procedure


Step 1 Select Design > Service Networks.

Step 2 Open the network that you just created if it is not already open.

Step 3 Click Summary. The Service Network Summary dialog box opens.

Step 4 Verify that the variable values you selected are correct.

Defining Server Groups

To define server groups, you must configure server group properties, such as the golden image, network interface (DHCP or Teaming mode), storage (NAS or SAN), sysprep, and swap size.

This procedure steps you through the process of defining server groups using the Server Group Configuration wizard.

Before You Begin

If you are using SAN management in fabric mode, make sure that your server is configured to boot from a Fibre Channel and LUN. Also, make a note of the LUN number because you will need to specify this number when you configure the server group. For details about configuring servers, Setting Up Application Servers, page 3-20.

Procedure


Step 1 Select Design > Service Networks.

Step 2 Open a service network and select a server group. The Server Group Definition tab opens.

Step 3 Click Configure... to open the Server Group Configuration wizard (see Server Group Configuration Wizard).

Step 4 Click Next to open the next dialog box.

Step 5 In the Golden Image Selection dialog box (see Golden Image Selection Dialog Box), do the following:

a. Select the golden image to be used to image servers.

b. Indicate the boot image type: NAS or SAN. Boot image is based on whether the golden image is block based or file based. File-based boot images are typically NAS, and block-based boot images are typically SAN.

c. If the boot image is file based, enter the minimum swap and memory size. When your service network is deployed, VFrame does not create the swap space you specify. It instead acquires servers with enough swap space already configured to accommodate your specification.

d. Click Next to open the next dialog box.

Step 6 If you have not defined variables for your golden image, proceed to Step 7. If you have defined variables for your golden image, the Golden Image User Variables dialog box opens (see Golden Image User Variables Dialog Box).

In this dialog box, do the following:

a. View or edit values for the golden image variables.

b. Click Next to open the next dialog box.

Step 7 In the Fabric and SAN Storage Selection dialog box (see Fabric and SAN Storage Selection Dialog Box), do the following:

a. Specify the type of fabric connectivity used. Valid values are No Fabric, Single Fabric, and Dual Fabric. Fabric mode is optional for NAS networks.

b. If single fabric is used, assign a VSAN to Fabric 1. If dual fabric is used assign VSANs to both Fabric 1 and Fabric 2.

c. Indicate the number of ports per fabric (1 through 8).

d. Click Next to open the next dialog box.

Step 8 If you selected SAN for the boot image type (Step 5), go to Step 9. If you selected NAS for the boot image type (Step 5), the NAS Storage Selection dialog box opens (see NAS Storage Selection Dialog Box).

In this dialog box, do the following:

a. Specify the NFS storage pool where server images will be stored. If necessary, you can create additional storage partitions by clicking the Add button and specifying the partition name, size, and NFS volume.

b. If your network is UNIX based, select the appropriate Qtree. If your network is Windows based, select the appropriate CIFS volume.

c. Click Next to open the next dialog box.

Step 9 In the LUN Selection for SAN Storage dialog box (see LUN Selection for SAN Storage Dialog Box), do the following:

a. If you selected single or dual fabric mode for NFS, one additional LUN must be created. Click Add, enter the name of the LUN, and select the storage pool from the available list.

b. If you selected single or dual fabric mode for SAN, one root LUN is already configured. Select that LUN in the table, click Edit and choose the storage pool for the root LUN.


Note Additional LUNs cannot be created for SAN root.


c. Click Next to open the next dialog box.

Step 10 In the Additional Logical Server Routing Configuration dialog box (see Additional Logical Server Routing Configuration Dialog Box), do the following:

a. If the default route specified under the Block Variables tab is sufficient, click Next and go to Step 11. Otherwise, configure additional routes for the server group by clicking Add and specifying the network address, netmask, gateway, and metric.

b. Click Next to open the next dialog box.

Step 11 In the Interface Properties for Link To_Layer2Switch dialog box (see Interface Properties for Link To_Layer2Switch Dialog Box), do the following:

a. Select the number and speed of Ethernet links.

b. If there are multiple interfaces, one interface must be marked as the VFrame communication interface by selecting the PXE Boot Interface check box.

c. If spanning tree PortFast should be configured on the switch ports attached to the deployed servers, select this check box. If selected, the following two commands are applied to the access switch ports:

spanning-tree portfast

spanning-tree bpduguard enable

d. Click Next to open the next dialog box.

Step 12 If you did not select the PXE Boot Interface check box, go to Step 13. If you selected the PXE Boot Interface check box (Step 11), the DHCP Options for Link To_Layer2Switch dialog box opens (see Teaming Mode for Link To_Layer2Switch Dialog Box).

In this dialog box, do the following:

a. Click Add and define a DHCP entry.

b. Click Next to open the next dialog box.

Step 13 If you selected only one Ethernet link, go to Step 18. If you selected two or more Ethernet links (Step 11), the Teaming Mode for Link To_Layer2Switch dialog box opens (see Teaming Mode for Link To_Layer2Switch Dialog Box).

In this dialog box, do the following:

a. Select the mode used for teaming. Valid values are active backup or balance TLB.

b. Select the Enable NIC HA check box to require NIC interfaces on different physical cards for this team.

c. Select the Switch HA check box to require NIC interfaces connected to different physical Ethernet switches for this team.

d. Click Next to open the next dialog box.

Step 14 In the Teaming Parameters for Link To_Layer2Swtich dialog box (see Teaming Parameters for Link To_Layer2Switch Dialog Box), do the following:

a. Click Edit to change the existing parameter name or values to meet your needs, or click Add to create new parameters.

b. Click Next to open the next dialog box.

Step 15 If the golden image you selected is not a Windows image, go to Step 17. If the golden image you selected is a Windows image, the Sysprep File Selection dialog box opens (see Sysprep File Selection Dialog Box).

In the Sysprep field, select the Sysprep file used to configure all the servers for the selected server group.

Step 16 If the golden image you selected is a Windows image, the Sysprep Variables dialog box opens (see Sysprep Variables Dialog Box). If you defined variables for the Sysprep file, enter values for those variables in the fields provided and click Next.

Step 17 If you defined variables for the golden image using the Server Images tab (see "Managing Server Images"), the Golden Image User Variables dialog box opens (see Golden Image Selection Dialog Box). Enter values for those variables in the fields provided and click Next.
