How to Set Up Nutanix Objects

View as Markdown

Nutanix Objects implements an Object Storage S3™ * compatible solution on your Nutanix cluster, using Prism Central. You can read the description on this link.

This guide will show you how to set up Nutanix Objects on your cluster.

Requirements

  • A Nutanix cluster in your OVHcloud account.
  • Access to the OVHcloud Control Panel.
  • You must be connected to the cluster via Prism Central.

Instructions

From Prism Central, click your cluster in the Cluster Quick Access widget to connect to Prism Element.

Set up Nutanix objects - step 1

 

Click your cluster's name in the top left-hand corner next to the X.

Set up Nutanix objects - step 2

 

Verify the IP Address in the ISCSI Data Services IP section, then click Save.

Set up Nutanix objects - step 3

 

Configuring VLANs in Prism Central

You need to create two additional VLANs in your cluster configuration and have these VLANs access Prism Central and Prism Element to configure Nutanix Objects. These two VLANs must be able to distribute IP addresses. IPAM will be enabled on both VLANs.

From Prism Central, go to the main menu and click on Subnets in the Network & Security category.

Set up Nutanix objects - step 4

 

Click Create Subnet.

Set up Nutanix objects - step 5

 

Check the IP Address Management box and fill in this information :

Then click the blue validation button ✓ on the right.

Set up Nutanix objects - step 7

 

Scroll down and enter the OVHcloud DNS address 213.186.33.99 in Domain Name Servers and click Create.

Set up Nutanix objects - step 8

 

Your first VLAN is created. We will create the second VLAN, click on Create Subnet.

Set up Nutanix objects - step 9

 

Check the IP Address Management box and fill in this information :

  • Name: Type public-storage.
  • Type: Select VLAN.
  • VLAN ID: Type your VLAN number as 101.
  • Virtual Switch: Keep vs0.
  • Network IP Address / Prefix: Write your subnet 192.168.101.0/24.
  • Gateway IP Address: Enter your gateway address 192.168.101.254.

Then click Add IP Pool.

Set up Nutanix objects - step 10

 

Enter this information :

  • Start Address: Start address of your scope as 192.168.101.10.
  • End Address: End address of your scope as 192.168.101.200.

Next, click the blue validation button ✓ on the right.

Set up Nutanix objects - step 11

 

Scroll down and enter the OVHcloud DNS address 213.186.33.99 in Domain Name Servers and click Create.

Set up Nutanix objects - step 12

 

Your two VLANs are created, make sure they can connect to Prism Element and Prism Central through your gateway. You can use this guide to replace the default gateway and use your VLANs: OVHgateway replacement.

Set up Nutanix objects - step 13

 

Enabling Nutanix objects in Prism Central

Go to the main menu, scroll to the Services section, and click Objects.

Set up Nutanix objects - step 14

 

Click Enable.

Set up Nutanix objects - step 15

 

Click Enable to validate the activation of Nutanix Objects.

Set up Nutanix objects - step 16

 

The service checks your system compatibility.

Set up Nutanix objects - step 17

 

Click Next.

Set up Nutanix objects - step 18

 

Click Create Object Store.

Set up Nutanix objects - step 19

 

Fill in this information :

  • Object Store Name: the name of your object storage, such as nutanix-objects.
  • Domain: The domain name that will be used to access your storage, such as mydomain.com.
  • Cluster: The cluster that must have Nutanix Objects enabled.
  • Worker Nodes: The number of nodes that your Object storage will use, select the number 1.

Then click Next.

Set up Nutanix objects - step 20

 

Select the VLAN object-storage in Storage Network and enter these two addresses 192.168.100.1,192.168.100.2 in Object Store Storage Network static IPs (2 IPs required). These addresses must not be within the scope of the VLAN DHCP.

Then click Next.

Set up Nutanix objects - step 21

 

Select the public-storage VLAN in Storage Network and enter this range of four addresses 192.168.101.1-192.168.100.4 in Public Network static IPs. These addresses should not be within the scope of the VLAN DHCP.

Next, click Save & Continue.

Set up Nutanix objects - step 22

 

A connection check is performed between the VLANs, Prism Element, and Prism Central.

Set up Nutanix objects - step 23

 

When validation is complete, click Create Object Store.

Set up Nutanix objects - step 24

 

Wait twenty minutes for your Object Storage to be active and accessible through the address 192.168.101.1 that is located in your public-storage VLAN.

Set up Nutanix objects - step 25

 

Creating an Access Key to your storage

To be able to use Object storage, it is necessary to create associated Access Keys.

Go to the Access Keys tab.

Warning

Note: Your access credentials are only displayed once in your web browser. Please note down this information (Access Key and Secret Key) before closing this window.

Set up Nutanix objects - step 31

 

Your user is created with its login details. You can regenerate Access Keys and create a new login.

Set up Nutanix objects - step 32

 

Validation and functional testing

To confirm that our Object storage is working properly, we will use the AWS awscli command-line tool and create a bucket. You can use this guide for more information.

The awscli tool is available on Windows, Linux, and macOS.

Use the following command for help:

aws s3 help

After installing awscli, we will create two configuration files on a computer that has access to the public-storage VLAN and use the aws command to create a bucket.

Create a .aws subfolder in your %USERPROFILE% folder on Windows, or $HOME on Linux and macOS.

Add the credentials file and fill it in with this data:

[default]
aws_access_key_id=your-access-key
aws_secret_access_key=secret-access key

Then add a second file named config with this information :

[default]
region=region = us-east-1

Then use this command to create a bucket.

aws --endpoint-url https://192.168.101.1 s3 mb s3://my-bucket --region=us-east-1 --no-verify-ssl

The bucket is created with a warning message about the SSL certificate. In a production environment, it is necessary to use an SSL certificate.

Now that the bucket is created we will use a browser to connect to the web interface provided by Nutanix to check the existence of our bucket.

Using a web browser, connect to this URL https://192.168.101.1/objectsbrowser which corresponds to your Nutanix Objects access point, and enter your credentials (access_key and secret_key). Then click on Login.

Set up Nutanix objects - step 33

 

You can see the bucket you created in the command line. You can create and delete buckets or objects in your web interface.

Set up Nutanix objects - step 34
