vSphere 8 – What’s New

I know many customers were waiting for the next release of VMware vSphere to realize the new capabilities and features. So there you go, Let’s check what’s new in vSphere 8!

VMware vSphere is the base solution on which most private cloud datacenters are running on. As VMware defines, vSphere 8 is the enterprise workload platform that brings the benefits of the cloud to on-premises workloads, supercharges performance through DPUs and GPUs, and accelerates innovation with an enterprise-ready integrated Kubernetes runtime.

In this post, I want to introduce the new and unique features that I found useful and interesting in vSphere 8.0!

My IT Journey!

I am thrilled to announce that I am starting a new position as a Senior Solution Engineer at VMware!

My name is Sadaf, I am originally Iranian, but I live in Sweden! I am a double VCIX, vExpert, and vSAN specialist with more than ten years of experience in Information Technology!

In this post, I want to share my journey with you, especially for women who want to start their career in IT but are hesitant because they are afraid of not being accepted or judged in this man-dominant field! I just forgot! Heh! I am also an expert at being judged and bullied but never get surrendered, thanks to my non-relevant bachelor’s! But you know what? I could do it, so can you!

I have studied Business Administration, but my path crossed with IT when I was on an internship about 12 years ago!

I was part of the sales engineering team responsible for helping customers get certified in the Information Security Management System(ISMS)/ISO 27001.

Configure vSAN Stretched Cluster

vSAN Stretched cluster introduced in vSAN 6.1 and it brings high availability in an active-active fashion. In this architecture, ESXi hosts would be placed in two different physical locations and join together with high bandwidth low latency networking. But from a management perspective despite hosts being in two different sites they belong to one single vSAN Cluster and share their resources. So this solution can be used in environments where disaster avoidance is a critical matter. Because it gives you the ability to avoid disaster, or recover from a disaster by having two different physical sites that host your applications. So you need to group the hosts based on their physical locations and put them in two different fault domains.

vSAN Deployment without existing vCenter Server

VMware vSAN is Software-Defined Storage(SDS) solution from VMware that is fully integrated into vSphere. To enable vSAN, we need to have a minimum of three ESXi hosts, and each host needs at least one cache disk and one capacity disk. The local disks of ESXi hosts should be formatted by VMFS. Since vSAN is a vSphere clustering feature, we should also have Center Server in place before start implementing it.

If you are a System Administrator or even a Solutions Architect, you might a face a challenge to build a vSAN Cluster with minimum ESXi servers without having a vCenter in place. In many green field environments, vCenter has not been installed and you want to keep ESXi’s disks intact and unformatted. In addition, there are some customers that want to build and manage vSAN Cluster in a separate vCenter and they do not have any additional ESXi host for vCenter deployment.

Critical vCenter Server Vulnerability – Patch Immediately!
