The landscape for VMware ESXi 5.5 licensing has shifted dramatically since its release. While once widely available through official VMware portals, the acquisition of VMware by Broadcom has fundamentally changed how legacy licenses and "Free Edition" keys are handled. Current State of ESXi 5.5 Licensing
VMware ESXi 5.5 is a legacy product that reached its End of General Support (EOGS) years ago. Because of its age, Broadcom has discontinued the issuance of new "free" license keys for this version.
Broadcom Portal Changes: Recent updates to the Broadcom Support Portal mean that standard registration for ESXi 5.5 is no longer an option for new users.
Evaluation Mode: By default, an installation of ESXi 5.5 starts in a 60-day evaluation mode with all features unlocked. After this period, virtual machines cannot be powered on or managed unless a valid license is applied. How to Assign a License Key
If you have an existing key, the process for applying it to your ESXi 5.5 host is straightforward:
Open the vSphere Client: Connect directly to your ESXi host.
Navigate to Licensing: Go to the Configuration tab, then select Licensed Features under the Software section.
Edit License: Click Edit in the top right corner and choose Assign a new license key to this host.
Enter Key: Input your 25-character alphanumeric key and click OK. Common Licensing Types for 5.5 License Tier Primary Use Case Free Hypervisor Home labs / Single hosts No vCenter support, limited physical CPUs, no vMotion. Essentials / Essentials Plus Small businesses
Includes vCenter Server and features like vMotion and High Availability. Enterprise Plus Large-scale production
Full suite of features including Distributed Switch and Storage DRS. Important Considerations
Hardware Compatibility: 5.5 is often used for older hardware that cannot run newer versions like ESXi 7.0 or 8.0. However, it does not receive critical security patches.
EULA Compliance: Free license keys are typically tied to a specific account and are non-transferable according to VMware's End User Licensing Agreement (EULA).
Upgrades and Downgrades: If you own a license for a newer version (e.g., vSphere 6.0), you may be able to downgrade the key in your Broadcom/VMware portal to generate a valid 5.5 key for your lab. vSphere 5.5 Free version licensing - physical CPU's limit
VMware ESXi 5.5, while a legacy hypervisor, remains a standard for managing virtual machines on older hardware. Licensing this version is essential to move beyond the 60-day evaluation period. Licensing Options for ESXi 5.5 Free Hypervisor License
: VMware previously offered a "Free" version of ESXi 5.5 with no physical RAM limits (a major upgrade from the 32GB limit in version 5.0). However, following Broadcom's acquisition of VMware, these free keys are no longer officially issued. Paid vSphere Licenses
: Standard, Enterprise, or Enterprise Plus keys unlock advanced features like vMotion, High Availability, and central management via vCenter. Evaluation Mode
: By default, ESXi 5.5 starts with a 60-day trial of all Enterprise Plus features. After 60 days, you must apply a key or the VMs will no longer power on. How to Apply a License Key You can apply your license key through the vSphere Client (the legacy Windows application required for version 5.5): Connect to your ESXi host using the vSphere Client Select the host in the inventory on the left. Configuration Under the "Software" section, click Licensed Features in the top right corner. Assign a new license key to this host and enter your 25-character key. Important Considerations for Version 5.5
Guide to Licensing VMware ESXi 5.5 Licensing VMware ESXi 5.5—an legacy version of the hypervisor—now requires navigating a landscape of end-of-life support and shifting ownership under Broadcom. This paper outlines how to obtain and apply keys for both free and paid versions, while addressing current availability. 1. Availability of Free License Keys
Historically, VMware provided a "Free Hypervisor" license for ESXi 5.5 that removed the 60-day evaluation period and allowed for unlimited physical CPUs.
Current Status: As of 2024, Broadcom has discontinued the free version of ESXi. Keys for legacy versions like 5.5 are no longer officially issued.
Legacy Keys: If you previously registered a key, it may still be accessible via your historical My VMware account portal.
Alternative Versions: Newer versions of VMware tools, such as VMware Workstation Pro, are now free for personal use. 2. How to Apply a License Key
If you possess a valid 25-character license key, follow these steps to activate your host: Using the vSphere Client:
Connect to your ESXi host or vCenter Server using the vSphere Client. Select the host in the inventory. Navigate to the Configuration tab. Under Software, select Licensed Features. Click Edit in the top right corner.
Select Assign a new license key to this host, enter your key, and click OK. Using the vSphere Web Client: Log in to vCenter Server and go to Administration. Select Licenses and click the License Keys tab. Click the + (Add) icon to enter your new key. 3. Critical Limitations & Considerations vSphere 5.5 Free version licensing - physical CPU's limit
VMware ESXi 5.5 reached its End of General Support on September 19, 2018, and its Technical Guidance Phase license key vmware esxi 5.5
concluded on September 19, 2020. Because it is a legacy, unsupported version, obtaining new license keys directly from the official Broadcom (formerly VMware) portal is no longer possible through standard modern channels. Obtaining and Managing License Keys
This review explores the legacy of VMware ESXi 5.5, an pivotal release in the virtualization world that fundamentally changed how users approached free-tier licensing. While this version is now largely obsolete and no longer officially supported, it remains a case study in high-value hypervisor features and the start of a major shift in enterprise licensing. The Big Shift: Removing the 32GB RAM Limit
The most significant "feature" of the ESXi 5.5 license was the removal of the 32GB physical RAM limit for the free version. Prior to this 2013 release, free-tier users were capped at 32GB, which severely limited home labs and small business servers.
Impact: By lifting this restriction, ESXi 5.5 allowed users to leverage affordable, high-memory hardware without paying for a Standard or Enterprise license.
Unlimited Physical CPUs: The free license worked for single-CPU and multi-CPU hosts, allowing for significant vertical scaling on a single machine. Features and Restrictions
While the RAM limit vanished, the ESXi 5.5 free license maintained several key constraints to encourage enterprise upgrades:
Management Limitations: It could not be managed by vCenter Server. Without vCenter, premium features like vMotion and High Availability (HA) remained locked.
API Write-Access: The free license provides "read-only" API access, meaning many third-party backup tools (like Veeam) could not perform automated backups without a paid version.
Virtual SMP: A hard limit of 8-way virtual SMP (8 vCPUs per VM) was enforced. Performance and Usability vSphere 5.5 Free version licensing - physical CPU's limit
