VMware vSphere 8 Update 2
One of the most important new features at VMware Explore 2023 will be vSphere 8 Update 2 (U2). This includes a cloud service for ESXi lifecycle management, faster vCenter upgrades, Azure AD support and improved GPU scalability. This move is part of a new release model where updates not only fix bugs, but continuously add new features.
ESXi Lifecycle Management: New Cloud Service in vSphere+
Lifecycle management is a top priority for VMware. Updates and upgrades to vSphere need to be done on a regular basis. This can be challenging as they can be very large. Rapid response is essential. This is where VMware comes in. It also makes it easier for IT administrators to centrally manage authentication.
The ESXi Lifecycle Management Service is a significant and important enhancement. It allows administrators to centrally orchestrate updates for their entire fleet of ESXi hosts. This reduces the time and effort required to manage the lifecycle of ESXi hosts.
Significantly reduced downtime for vCenter upgrades.
vCenter downtime during an upgrade is reduced from approximately one hour to a few minutes. This is essentially the time it takes to stop services on the old vCenter and start them on the new vCenter. As a result, scheduled maintenance windows are shortened and upgrades can be performed more frequently.
Simplify security audits with Entra ID
For example, VMware has expanded support for Microsoft Entra ID (formerly Azure AD) in recent years, including Microsoft Active Directory Federation Service (ADFS) and, more recently, Okta Identity Service. When authentication is performed using a third-party provider such as Entra ID, the authentication is no longer handled by vSphere. Logins and passwords are therefore no longer stored in vSphere, making security checks easier, faster or even unnecessary.
Double workload performance
Increases the maximum number of vGPUs per VM from 8 to 16. Larger workloads require more GPU power. This latest release increases the maximum number of vGPU devices that can be assigned to a single VM to 16. VMware has doubled the upper performance limit.
At the same time, the GPU-enabled DRS workload has also been improved. DRS now recognises vGPU profile sizes and consolidates vGPUs of the same size on the same host. As a result, the improved GPU resource utilisation results in lower costs because less GPU hardware resources need to be purchased to achieve the desired performance level.
Accelerate innovation for DevOps
In vSphere 7 Update 2a, VMware introduced the Virtual Machine Service, which enables developers and DevOps to manage VMs using Kubernetes APIs. In vSphere 8 U2, the VM Image Registry Service is added to make it easier to reuse VM images. This service allows images to be published, customised and deleted via Kubernetes APIs.
Previously limited to Linux VMs, the Virtual Machine Service in vSphere 8 U2 now supports Windows VMs and removes many hardware restrictions, including the use of GPUs. In addition, Update 2 provides the ability to export the configuration of a Supervisor cluster and import it onto a new cluster, greatly simplifying setup.
