Spotlight: A DIY Guide of ESXi Host Product Locker

Introduction

In VMware vSphere, ESXi hypervisor is the backbone of many virtualization environments, and optimizing its configuration and management is crucial for a smooth vSphere experience. One often-overlooked aspect is the Product Locker, a directory on ESXi hosts that stores installation and update packages. In this article, we’ll explore the tips and tricks for effectively managing the ESXi Host Product Locker for your vSphere environment.

Prerequisites

Before we begin, make sure you have the following:

1. Access to the vSphere environment.
2. A basic understanding of ESXi and vSphere concepts.

Understanding ESXi Host Product Locker

Let us understand. What is the Product Locker – The Product Locker is a directory on each ESXi host that contains installation and update packages for the ESXi software, drivers, and other software components.  It’s an essential part of maintaining and updating it within a vSphere environment.

The Role of the Product Locker

The Product Locker serves several vital functions, including how to store installation packages for ESXi, which can be used for fresh installations and updates. It also keeps the copies of third-party software, drivers, and CIM providers that are used on the host. It provides easy access to these packages for installations and updates without requiring external repositories or resources.

Configuring and Managing the Product Locker - To configure shared VMware Tools Repository

Step 1: Log in to the ESXi host using the vSphere Client or SSH.

Step 2: Navigate to the /locker directory to access the Product Locker.

Step 3: Create a folder on shared iscsi datastore.

Step 4: Bring all contents from, Host’s local product locker to shared datastore.

Step 5: Restart your ESXi host.

Step 6: Make sure to repeat above steps for all ESXi hosts of your environment to maintain consistency.

Step 7: Validate all ESXi settings.

Increasing Product Locker Capacity

To prevent the Product Locker from running out of space, you can increase its capacity:

1. Identify the local storage where the Product Locker is located.
2. Add additional storage to the ESXi host if needed.
3. Relocate the Product Locker to the newly added storage if necessary.

Managing Packages in the Product Locker

Regularly update it with the latest patches and updates using the packages stored in the Product Locker.  Always remove old or unnecessary packages to free up space.

Best Practices and Tips

Keep It Updated:  Ensure that your Product Locker contains the latest ESXi patches and updates to maintain the security and reliability of it.

Regularly Audit Storage

Periodically review the Product Locker’s storage usage. If it’s running low on space, consider offloading older packages to external storage.

Automate Updates

Leverage vSphere Update Manager (VUM) to automate the process of updating ESXi hosts. VUM can use the Product Locker to stage updates.

Documentation and Naming Conventions

Document the contents of your Product Locker, especially when adding third-party software and drivers. Use clear and consistent naming conventions for packages.

Backup the Product Locker

Consider regular backups of the Product Locker to prevent data loss in case of hardware failure.

Conclusion

The ESXi Host Product Locker is a critical component for managing and maintaining your hosts within a vSphere environment. By understanding its role, configuring it efficiently, and following best practices, you can ensure the smooth operation and security of your virtualization infrastructure. Regular audits, updates, and proper documentation will contribute to a well-managed Product Locker and a more reliable vSphere environment.
