Difference between vSphere 4.0 and 4.1

VMware vSphere is a suite of virtualization products designed to provide efficient, reliable, and scalable server consolidation. The first version, VMware vSphere 4.0 (codenamed “Vienna”), was released on August 9, 2009. The second major release, VMware vSphere 4.1 (codenamed “Bordeaux”), was released on September 22, 2010. This paper discusses the key features of VMware vSphere 4.0 and how they compare to those in VMware vSphere 4.1. It also covers some of the changes in licensing between the two releases.

What is vSphere 4.0?

vSphere 4.0 is the latest release of VMware’s virtualization platform. It offers a number of significant improvements over previous versions, including enhanced performance, scalability, and security. vSphere 4.0 also introduces a new storage architecture that allows for more efficient use of storage resources. In addition, vSphere 4.0 includes a number of other features and enhancements that make it the most powerful and comprehensive virtualization platform available today. Whether you’re looking to improve your server utilization or consolidate your data center, vSphere 4.0 has the features and functionality you need to get the job done.

What is vSphere 4.1?

vSphere 4.1 is a virtualization platform from VMware that enables the creation of virtual machines (VMs) on a physical server. By creating VMs, multiple operating systems and applications can run on the same server, increasing utilization and reducing server costs. vSphere 4.1 provides features such as high availability, fault tolerance, and live migration that help to ensure the continuous operation of business-critical workloads. In addition, vSphere 4.1 offers powerful security features that can help to protect sensitive data. Overall, vSphere 4.1 is a robust virtualization platform that can help organizations to improve efficiency and reduce costs.

Difference between vSphere 4.0 and 4.1

VMware vSphere is a virtualization platform that enables you to run multiple virtual machines on a single physical server. vSphere 4.0 was released in 2010 and vSphere 4.1 was released in 2011. Both versions offer significant advantages over previous versions, including increased scalability, performance, and security.

  • One of the biggest differences between vSphere 4.0 and 4.1 is scalability. vSphere 4.0 supports up to 320 logical processors and 64TB of memory, while vSphere 4.1 supports up to 640 logical processors and 2PB of memory. This means that vSphere 4.1 can handle far more demanding workloads than its predecessor.
  • Another difference is performance. vSphere 4.0 introduced a number of features designed to improve performance, including CPU overcommitment and memory ballooning. vSphere 4.1 builds on these foundations by adding support for hardware-accelerated 3D graphics and solid-state drives. These enhancements mean that vSphere 4.1 can deliver even better performance than its predecessor.
  • Finally, vSphere 4.1 includes a number of security enhancements that are not present in vSphere 4.0. These include support for encrypted vMotion and data at rest encryption. These features make it even more difficult for attackers to gain access to sensitive data or disrupt operations.

Overall, both vSphere 4.0 and 4..1 offer significant advantages over previous versions of the platform. However, vSphere 41 provides even greater scalability, performance, and security than its predecessor, making it the best choice for most organizations.


If you are looking to upgrade your virtualization software, it is important to understand the differences between vSphere 4.0 and 4.1. The changes in 4.1 may be just what you need to take your business to the next level.
