# Request a core limit increase
16
+
16
17
If you reach the cores limit for your subscription, you can request a core limit increase (sometimes called an increase in capacity, or a quota increase) to continue using Azure Lab Services. The request process allows the Azure Lab Services team to ensure your subscription isn't involved in any cases of fraud or unintentional, sudden large-scale deployments.

## Prepare to submit a request
22
+
20
23
Before you begin your request for a core limit increase, you should make sure that you have all the information you need available and verify that you have the appropriate permissions. Gather information like the number and size of cores you want to add, the regions you can use, and the location of resources like your existing labs and virtual networks.
21

25
### Permissions
26

23
27
To create a support request, you must be assigned to one of the following roles at the subscription level:
Before you begin calculating the number of extra cores you require, verify the capacity available in your subscription by [determining the current usage and quota](./how-to-determine-your-quota-usage.md). You'll be able to see exactly where your current capacity is used, and may discover extra capacity in an unused lab plan or lab.

### Determine the regions for your labs
38
+
32
39
Azure Lab Services resources can exist in many regions. You can choose to deploy resources in multiple regions close to your students. For more information about Azure regions, how they relate to global geographies, and which services are available in each region, see [Azure global infrastructure](https://azure.microsoft.com/explore/global-infrastructure/products-by-region/).

### Determine the total number of cores in your request
35
42
36
-
Your cores can be divided amongst virtual machines (VMs) of different sizes. You must calculate the total number of cores for each size. You must include the number of cores you already have, and the number of cores you want to add to determine the total number of cores. You must then map the total number of cores you want to the SKU size groups listed below.
43
+
In the request for additional VM cores, you need to calculate the total number of cores. This total includes both your existing number of cores, and the cores you want to add.

44
38

**Size groups**
45
+
Azure Lab Services groups some VM sizes together in size groups:
39
46
40
-
Azure Lab Services groups SKU sizes as follows:
41
47
- Small / Medium / Large Cores
42
48
- Medium (Nested Virtualization) / Large (Nested Virtualization) Cores
43
49
- Small (GPU Compute) Cores
44
50
- Small GPU (Visualization) Cores
45
51
- Medium GPU (Visualization) Cores
46
52
47
-
To determine the total number of cores for your request, you must:
48
-
1. Select the VM sizes you want
49
-
2. Calculate the total cores needed for each VM size
50
-
3. Map to SKU group and sum all cores under each group
51
-
4. Enter the resulting total number of cores for each group in your request

1. Select the VM size you want.

2.**Next calculate the total cores needed for each VM size.**

Using the figures in the table above and the number of cores for each size in the dropdown, you can calculate the total number of cores as shown:
67
-
- *Small:* 40 small VMs x 2 cores = 80 cores
68

- *Large:* 3 large VMs x 8 cores = 24 cores

75
-
Requested total core limit for Small / Medium / Large = 80 + 24 = 104 cores
76

The large nested virtualization VM is grouped separately:
78

Requested total core limit for Medium (Nested Virtualization) / Large (Nested Virtualization) = 8 cores

When you request core limit increase, you must supply some information to help the Azure Lab Services team evaluate and action your request as quickly as possible. The more information you can supply and the earlier you supply it, the more quickly the Azure Lab Services team will be able to process your request.
