Managing Resource Pools

---

Resource pools help you organize your resources to make it easier to make appropriate allocations to your virtual contexts. Each asset type in each virtual context has a default resource pool, but administrators in the Admin context, or in virtual contexts that have more than one service network, will probably benefit from creating additional pools to create subsets of resources.

These topics more fully describe resource pools, how to create them, and what you can do with them:

Resource Pool Overview

A resource pool is a named collection of assets of a particular type of resource. For example, you can create a pool of servers, or a pool of Catalyst 6500 switches, but you cannot create a pool that contains a mix of servers and switches.

Each virtual context, including the Admin context, has a set of default resource pools, one for each type of resource, that start with the word "All." Pool names include the name of the context plus the name of the pool. For example, AdminContext: All Server is the name of the default server pool in the Admin context.

Default pools contain all resources (of the given type) that appear within the context. Admin context default pools contain all assets; virtual context default pools contain the assets assigned to the virtual context from the Admin context.

With two exceptions, all pools, whether default or user-created, contain resources added only through discovery (performed in the Admin context). However, in the Admin context, you can also add undiscovered resources to these pools (and to user-created pools for these types of resources):

•AdminContext: All IP Address Range—The IP address range pool contains the ranges of IP addresses that can be assigned to resources acquired for use by service networks. The administrator must add IP address ranges and assign at least one IP address pool to each virtual context.

•AdminContext: All VLAN (VFrame Created)—You can add VLANs that have not been discovered. If you assign one of these VLANs to a service network, VFrame to creates it on the managed Ethernet switches.

After creating resource pools, you can assign them to virtual contexts if you are using virtual contexts. Nondefault pools appear in the virtual context and the contents of the all assigned pools appear in the virtual context's default pools.

Keep in mind that a resource can belong to more than one pool. All resources show up in the default pools, and each resource can show up in one or more additional pools based on your needs.

Static and Dynamic Resource Pools

There are two functional types of resource pools:

•Static—A static resource pool contains only those resource you specifically assign to the pool. Resources are removed from the pool only if you manually remove them or if they are marked as unmanaged in the Admin context.

•Dynamic—A dynamic pool is defined by a set of rules that specify what types of resources belong to the pool. For example, you could create a dynamic pool of servers whose processor speed is greater than 2000 MHz. The software evaluates your rules, compares them to the resources defined in the system, and adds only those resources that satisfy your rule set. As you manage or unmanage resources, a dynamic pool's contents change accordingly without requiring manual intervention.

Dynamic pools are especially valuable if your applications require specific types of hardware or performance characteristics. You can create a pool whose rules define these characteristics and assign only that pool to the service network that runs the application.

VFrame reassesses membership of dynamic pools whenever you modify the pool, change the managed state of an asset within the pool, assign a pool to a virtual context (the default pools in the virtual context are reassessed), or remove an asset from a static pool in the Admin context (virtual context default pools are reassessed).

Dynamic Pool Rules and Expressions

Membership in dynamic resource pools is controlled by an expression made up of rules. These rules define the attributes that a resource must have to be included in a group.

The types of attributes on which you can define rules depend on the type of resource. For example, server attributes differ from logical unit number (LUN) attributes. Explore the attributes available for your type of resource before deciding how you want to define pool membership. For information on viewing these attributes, see Creating Dynamic Resource Pools.

When you create dynamic resource pools, try to keep your rule set simple by keeping these points in mind:

•If you select Match all of the following, every rule must be satisfied by a resource for it to be placed in the pool.

•If you select Match any of the following, if a resource satisfies any single rule in the expression, it is placed in the pool.

When defining a rule, you select the attribute, then the operator that defines the relationship to the value you are testing for, and then the value. For example, the following rule is based on CPU speed, selecting only those servers with greater than 1 GHz CPU speed:

PhysicalServer.cpuSpeedInMHz > 1000

In this example, PhysicalServer.cpuSpeedInMHz is the attribute, > is the operator, and 1000 is the value (for this attribute, in megahertz).

The next example adds an additional constraint: The server must also have more than 1 GB of memory:

PhysicalServer.cpuSpeedInMHz > 1000 AND

PhysicalServer.memorySizeInMB > 1000

You can also do exact-value and partial-value matching by using these operators:

•= (the equals sign)—The attribute must contain the exact value. For example, the following rule matches only those servers that have Qlogic HBAs (the attribute associates an integer to each HBA vendor, and the mapping is displayed in the GUI):

PhysicalServer.fcInterfaces.vendor = 2

•!= (an exclamation point followed by an equals sign)—The attribute must not contain the exact value. Use this operator to apply a negative exact-match test. For example, the following rule excludes all servers that have unsupported HBAs (those defined as "other vendor"):

PhysicalServer.fcInterfaces.vendor = 3

•contains—The attribute must contain the value anywhere within the attribute. For example, the following rule matches any IP address that includes 100 in any octet:

PhysicalServer.lom.ipAddress contains 100

•does-not-contain—The opposite of contains, the attribute cannot include the value anywhere within it. For example, the following rule excludes all IP addresses that include 100 in any octet:

PhysicalServer.lom.ipAddress does-not-contain 100

•begins-with—The attribute must start with the value. For example, the following rule selects all IP addresses on 10.100.0.0 network:

PhysicalServer.lom.ipAddress begins-with 10.100

•ends-with—The attribute must end with the value. For example, the following rule selects all IP addresses that end in 13, including 13, 113, and 213, on all subnets:

PhysicalServer.lom.ipAddress ends-with 13

How VFrame Uses Resource Pools

VFrame uses resource pools when acquiring resources whenever you deploy a service network. In the service network definition, you select a pool or resources from within a pool. When you deploy the service network, if you selected a pool, VFrame finds an available resource in the pool and acquires it. If you selected a specific resource within a pool, that resource must be available or you cannot deploy the network.

If you later remove the resource from the pool, nothing happens to the service network. The resource is not suddenly removed from operation. Only if you undeploy and redeploy the service network does VFrame acquire a new resource from the pool. Thus, changes to dynamic pools, or changes you make to static pools, do not affect your running applications; they are protected.

Working with Resource Pools

These topics describe how to create and manage resource pools:

•Creating Static Resource Pools

•Creating Dynamic Resource Pools

•Changing the Contents of a Static Resource Pool

•Adding IP Address Resources

•Adding New VLAN Resources

•Editing or Modifying Resource Pools

•Deleting IP Address Ranges or VFrame-Created VLANs

•Deleting Resource Pools

Creating Static Resource Pools

Static resource pools contain only those resources you assign to them manually. These pools are useful if you are dealing with only a small number of assets, or if your selection criteria are too complex to develop a rule-based dynamic pool. For example, if you know that your finance group owns specific servers, you can create a static pool and add just those specific servers.

Before You Begin

Obtain a list of the resources that should be placed in the pool. Most resources must already be discovered and placed in the managed state before you can put them into pools. If you are creating a pool for IP address ranges or VFrame-created VLANs, you must add these resources to the default pools before you can copy them to your new static pools. See these sections for information on adding these types of resources:

•Adding IP Address Resources

•Adding New VLAN Resources

If you are creating a pool within a virtual context, you can pick only from resources that the Admin context administrator assigned to your virtual context.

Procedure

---

Step 1 Select Tools > Pools to open the Pools tab (see Pools Tab).

Step 2 Click New > Resource Pool to open the Create Resource Pool dialog box (see Create and Edit Resource Pool Dialog Boxes).

Step 3 In the Create Resource Pool dialog box:

•Enter a name and optionally a description for the pool.

The name of the virtual context in which you are creating the pool is prefixed to this name (for example, if you enter Finance Servers in the Admin context, the full name is AdminContext: Finance Servers).

•Select Static for Pool Type to create a static pool.

•Select the type of resource the pool contains.

Step 4 Click OK when finished and the pool is created and added to the list of pools.

Step 5 Add resources to the pool:

a. Find the pool that contains the resource that you want to add to the pool. It is typically the default pool for the resource type, but you can use user-created pools.

b. Select the desired resource and click Copy to Pool. The Copy Resources dialog box is opened, where you can choose the resource pool to which you want to add the resource.

c. Select the pool and click OK. Repeat this process until you have copied all desired assets into the pool.

Creating Dynamic Resource Pools

Dynamic resource pools contain only those resources that satisfy the rules you define for the pool. You define the criteria that a resource must meet in order to be included in the pool.

Dynamic pools are useful if you are dealing with a large number of assets, or if you frequently add resources to or remove them from the system. They are also useful if you must ensure that resources meet certain minimum criteria to be used in the service networks to which you assign the pool. For example, if you know that a service network can use only servers that run above a certain processor speed, you can use that attribute to define the membership of the pool.

Before You Begin

You can use many different attributes to build rules, and the available attributes differ depending on the type of resource. To explore the types of attributes you can use, follow this procedure to get to the Create Resource Pool dialog box. In this dialog box, you can explore the attributes available for the selected resource type and plan how to create meaningful rules to fit your specific requirements.

You can also select the default pool for the type of resource your pool will contain, and click Properties. This displays the values for some of the attributes you can use to create dynamic rules. This will help you identify strings or other values to use in dynamic rules.

Procedure

---

Step 1 Select Tools > Pools to open the Pools tab (see Pools Tab).

Step 2 Click New > Resource Pool to open the Create Resource Pool dialog box (see Create and Edit Resource Pool Dialog Boxes).

Step 3 In the Create Resources Pool dialog box:

•Enter a name and optionally a description for the pool.

The name of the virtual context in which you are creating the pool is prefixed to this name (for example, if you enter Finance Servers in the Admin context, the full name is AdminContext: Finance Servers).

•Select Dynamic for Pool Type to create a dynamic pool. The Rules and Expression groups are enabled.

•Select the type of resource the pool contains.

Step 4 In the Rule and Expression sections of the dialog box, add the rules that define the resource to be included in the pool. Before creating an expression, read the conceptual information and examples in Dynamic Pool Rules and Expressions.

To create the expression, add as many rules as you require:

•In the Match all/any of the following field, select how multiple rules should be evaluated. Select all if all rules must be satisfied for pool membership; rules are linked by AND. Select any if only one of the rules must be satisfied for pool membership; rules are linked by OR.

•To create a rule, select the attribute you want from the Attribute list, then select the desired operator and enter the value for which you want to test. Click Add to add it to the expression.

•To delete a rule, select the rule in the Expression Panel and click Delete. The logical operand preceding the rule is also deleted.

•To test your rule, click Preview Resources. VFrame evaluates your rule and opens the Resources List dialog box to show you the resources that would be part of the pool based on the rule.

Step 5 When your expression is correct, click OK to create the resource pool.

Changing the Contents of a Static Resource Pool

You can add resources to or remove them from a static resource pool.

If a resource is being used by an operating service network, removing the resource from a pool does not affect the service network. The resource remains part of the network until the network needs to reacquire resources.

You cannot manually change the contents of a dynamic resource pool. Instead, you must modify the pool's rules that define its contents. For more information, see these topics:

•Creating Dynamic Resource Pools

•Editing or Modifying Resource Pools

Before You Begin

Most resources must already be discovered and placed in the managed state before you can put them into pools. You must add IP address ranges or VFrame-created VLANs to the default pools before you can copy them to a user-created pool. See these sections for information on adding these types of resources:

•Adding IP Address Resources

•Adding New VLAN Resources

If you are in a user-created virtual context, you are able to choose only from resources assigned to your context.

Procedure

---

Step 1 Select Tools > Pools to open the Pools tab (see Pools Tab).

Step 2 To add a resource to a static resource pool:

a. Find the pool that contains the resource that you want to add to the pool. This is typically the default pool for the resource type, but you can use user-created pools.

b. Select the desired resource and click Copy to Pool. The Copy Resources dialog box is opened, where you can choose the resource pool to which you want to add the resource.

c. Select the pool and click OK.

Step 3 To remove a resource from a static resource pool:

a. Select the resource pool from which you want to delete the resource.

b. Either select the resource in the right pane or click the + icon for the resource pool and select the desired resource in the left pane.

c. Click Remove From Pool. The resource is removed from the pool, but it is not removed from the system, and its managed state does not change.

Adding IP Address Resources

Resources pools for IP address ranges do not contain discovered assets; you manually enter the address ranges included in the pool. VFrame uses the IP addresses identified by these ranges when assigning IP addresses to acquired resources during service network operations. You cannot operate a service network without defining at least one IP address range.

If you are logged into the Admin context, you can add any routable IP address range. If you are logged into a user-defined virtual context, you can define ranges only within the range already assigned to the virtual context from the Admin context.

The range cannot overlap the IP addresses ranges defined for DHCP address ranges. The DHCP addresses are exclusively used for server discovery and golden image creation. For more information about DHCP IP address ranges, see Understanding How VFrame Uses DHCP.

Procedure

---

Step 1 Select Tools > Pools to open the Pools tab (see Pools Tab).

Step 2 Click the New > IP Address Range Resource button. The Create New IP Address Resource dialog box opens (see Create New IP Address Resource Dialog Box).

Step 3 Enter the IP address range using one of these methods:

•Select Network Address and enter the address of a network VFrame can use. For example, 10.100.50.0. Then, select the subnet mask.

All addresses except the network address and the broadcast address are added to the pool. For example, 10.100.50.0/24 defines the address range 10.100.50.1 to 10.100.50.254.

•Select Begin IP and enter the first IP address number in the desired range and enter the last IP address in the End IP field. Then, select the subnet mask.

Specifying an address range is useful if some addresses in the network are statically assigned to certain devices (for example, a router interface), or addresses that VFrame should not manage.

To enter a single IP address, enter the same address in both the Begin and End IP address fields.

Step 4 Click Save. Before saving the changes, VFrame does the following:

•Verifies that the IP address ranges do not overlap with any address ranges defined in the DHCP IP address range table, whose ranges are used for server discovery and golden image creation. VFrame cannot use these addresses for service network operations.

•Verifies that the IP address ranges do not include any IP addresses assigned to VFrame's interfaces.

If the address range passes the tests, it is created in the All IP Address Range pool.

---

Tips

•If you want the new resources to reside in a user-created static pool, select them in the default pool, click Copy to Pool and select the desired pool.

•You cannot modify the properties for an IP address range after you create it. To change properties, delete the resource and recreate it.

•VFrame must have a route to these address ranges. If VFrame's default gateway does not include a route, configure a static route as described in Configuring Static Routes, page 18-8.

Adding New VLAN Resources

When VFrame discovers your Ethernet switches, it also discovers the VLANs defined on them. If you want to allow VFrame to create additional VLANs, you can identify them in a VLAN (VFrame-created) pool. When you assign a VFrame-created VLAN to a service network, VFrame configures the necessary switched virtual interface (SVI) and DHCP helper addresses for the VLAN.

VFrame cannot use VLANs numbered higher than VLAN 1001.

You can add VFrame-created VLANs only when you are logged into the Admin context.

Procedure

---

Step 1 Select Tools > Pools to open the Pools tab (see Pools Tab).

Step 2 Click the New > VLAN Resource button. The Create New VLAN Resource dialog box opens.

Step 3 Enter the first and last VLAN identifiers in the range you want to add.

For example, to add all VLANs in the 200 range, enter 200 as the beginning ID, and 299 as the ending ID. To add a single VLAN, enter the VLAN ID in both the BeginVLAN ID and End VLAN ID fields.

When finished, click OK in the dialog box to add the resource to the All VLAN (VFrame Created) pool.

---

Tips

•If you want the new resources to reside in a user-created static pool, select them in the default pool, click Copy to Pool and select the desired pool.

Editing or Modifying Resource Pools

After creating a resource pool, you can modify its properties as your needs change.

If you make a change to the expression that defines the content of a dynamic pool, and the change affects which resources are contained in the pool, these changes do not affect any service networks that have acquired a resource from the pool. Even if you remove that resource from the pool, service networks do not release these resources just because they are no longer in the assigned pool.

If you want to change the resources assigned to a static resource pool, see Changing the Contents of a Static Resource Pool.

Procedure

---

Step 1 Select Tools > Pools to open the Pools tab (see Pools Tab).

Step 2 To change the characteristics of the pool, select it and click Edit to open the Edit Resource Pool dialog box (Create and Edit Resource Pool Dialog Boxes).

You can change these characteristics:

•The description.

•For dynamic pools, the expression that defines the pool's contents. For information on building expressions, see these topics:

Deleting IP Address Ranges or VFrame-Created VLANs

You can delete IP address ranges or VFrame-created VLANs from their default resource pools. These are resources you define in VFrame, rather than those that are discovered in your network.

Before You Begin

Ensure that the resource you are deleting is not being used by a service network.

Procedure

---

Step 1 Select the resource you want to delete in either the All IP Address Range or All VLAN (VFrame Created) resource pools.

Step 2 Click Delete. The resource is removed from the pool and deleted from the system.

Troubleshooting Resource Pools

These are some problems you might encounter with resource pools and their solutions:

•You cannot see a pool that you expect to see within a particular virtual context.

•You cannot see any pools within a virtual context.

•A resource is not included in a dynamic pool when you think it should be.

•A resource is not included in a static pool when you think it should be.

•VFrame cannot communicate with an IP address in an IP Address Range pool.

Problem   You cannot see a pool that you expect to see within a particular virtual context.

Solution   Within a virtual context, you can see only pools that were created from within the context. Pools assigned from the Admin context define only the resources assigned to the context and these resources appear in the default resource pools. In addition, your user account might restrict you from seeing specific pools if your account specifies that you are allow to view specific service networks (this applies only in a virtual context). If you are not an administrator, ask your administrator to check on your user restrictions. If you are an administrator, log into the Admin context and check pool and user assignments for the virtual context, and whether the user is restricted by service network assignments.

Problem   You cannot see any pools within a virtual context.

Solution   When your user account is created for a virtual context, the account also includes a resource domain scope based on service networks. The person who creates your account must either select All, to give you access to all service network resources, or select specific service networks. A selection must be made or you will not see any resource pools, because you are not authorized to see any.

Problem   A resource is not included in a dynamic pool when you think it should be.

Solution   A dynamic resource pool contains only managed resources, so if a resource is marked as unmanaged, it is removed from the pool. If you do not have permission to view the resource on the Resources tab, ask the administrator to check on the managed state of the device. If this is not the problem, recheck the rules for the pool and compare them to the attributes of the resource (gather these from the device itself).

Problem   A resource is not included in a static pool when you think it should be.

Solution   Static pools contain just those resources that were specifically added to the pool. However, if a resource is unmanaged (in the Admin context), it is removed from all pools. If it is put into managed state again, the resource must again be manually added to the static pool: it is not added automatically. If the resource has been managed again, you can find it the default pool and add it back to the resource pool. If you cannot find it in the default pool, and you do not have permission to view the resource on the Resources tab, ask the administrator to check on the managed state of the resource and to remanage it or troubleshoot the problem as necessary.

Problem   VFrame cannot communicate with an IP address in an IP Address Range pool.

Solution   VFrame must have a route to a network address space in order to manage the network. If VFrame's default gateway does not have a route to the network, you must configure a static route on the VFrame Data Center Director to the network. For information on configuring static routes, see Configuring Static Routes, page 18-8.

Use the Create New IP Address Resource dialog box to define IP addresses that VFrame can use when assigning addresses to acquired resources such as servers. These addresses are used during service network operations.

VFrame must have a route to any network or IP address range you specify. If VFrame's default gateway does not have a route, you must configure a static route as described in Configuring Static Routes, page 18-8.

If you are logged into a user-defined virtual context (that is, not the Admin context), you can define ranges only within the range already assigned to the virtual context from the Admin context.

The range cannot overlap the IP addresses ranges defined for DHCP address ranges. The DHCP addresses are exclusively used for server discovery and golden image creation. For more information about DHCP IP address ranges, see Understanding How VFrame Uses DHCP.

How to Get to This Dialog Box

Click New > IP Address Range Resource on the Pools Tab (select Tools > Pools).

VFrame adds all addresses in the network to the pool except the network address and the broadcast address. For example, network 10.100.50.0/24 defines addresses 10.100.50.1 to 10.100.50.254.
Begin IP	Select to add a specific address range to the resource pool. Enter the first IP address in the range of addresses that VFrame can assign to acquired resources.
End IP	The last IP address in the range.
Subnet Mask	The subnet mask for the network address or the IP addresses in the identified range.
