vSphere 7 highlights include native Kubernetes support

vSphere 7 highlights include native Kubernetes support
All too often, companies release new versions of their solutions that promise big enhancements, but then fall short of delivering anything genuinely innovative. This is not the case with VMware’s recent release of vSphere 7.

Here are just a few of the significant enhancements to vSphere that can impact the solutions you’re offering to your customers:

vSphere with Kubernetes
Probably the most significant improvement to vSphere 7 is native Kubernetes support, allowing you to run VMs and containers on the same platform. vSphere with Kubernetes uses what VMware is calling Namespace, which should appeal to both admins and developers. According to Michael Cui, member of technical staff, office of the CTO at VMware, “a Namespace defines a logical set of resources, permissions and policies that enable application-centric management at scale for system admins. At the same time, AI/ML developers and users now gain access to the infrastructure through familiar Kubernetes APIs.” The integration of vSphere and Kubernetes is significant, delivering exciting new possibilities for streamlined development, agile operations and accelerated innovation to you and your customers.

Improved DRS (distributed resource scheduler)
A new DRS algorithm in vSphere 7 takes a workload-centric approach to decide placements and keep VMs operating efficiently. “The new DRS quantifies VM efficiency and effectiveness by using a VM DRS score, which considers various resource contention metrics, such as CPU Ready Time and memory swap, and also resource headroom for application bursting,” explains Cui. “Rather than using the previous five-minute interval, DRS now runs every minute to achieve finer granularity and better responsiveness.”

VMware Bitfusion in vSphere
With the release of vSphere 7, VMware Bitfusion is now available via beta. Cui reports that Bitfusion allows workloads to run anywhere while redirecting accelerated portions of code to be run on a remote accelerator-attached host. With VMware Bitfusion, admins can create a resource pool of accelerators that can power a broader collection of AI/ML users efficiently and flexibly.

Simplified lifecycle management
Cui says that vSphere 7 also introduced the next generation of vSphere Lifecycle Manager (vLCM) that allows users to manage the lifecycle of a cluster using a declarative approach. “Admins can now use vCenter Server Profiles to standardize on a configuration for all of their vCenter servers and use Cluster Image Management to create images that dictate how hosts within the cluster will be configured or updated to.”

vMotion enhancements
An update to vMotion includes several performance advances. “vMotion now supports live migration of VMs that run large databases and mission-critical workloads as well as large VMs used for HPC and ML workloads,” says Cui. “Page tracers are changed from running on all vCPUs inside a VM to a dedicated vCPU to mitigate application performance interference. Additionally, updating page table entries become more efficient with support for ‘Huge Pages’ in vSphere. Finally, the size of bitmap that records modified memory pages has been reduced to minimize switch-over time.”
