Reading Time: 3 minutesVMware vSAN does not need anymore an introduction: is the Hyperconverged Infrastructure (HCI) solution from VMware integrated in the ESXi kernel… and is growing more and more in the last years and more more than 500,000 VMware customers for years. There are different way to implement a vSAN solution and one common approach remain to build yourself using vSAN Ready Nodes or certified hardware components.
Reading Time: 3 minutesVMware vSphere Update Manager (VUM) enables centralized, automated patch and version management for VMware vSphere and offers support for VMware ESXi hosts, virtual machines, and virtual appliances. For ESXi hosts it can manage both the update and the upgrade workflows, but can also be powerful for adding custom VIB package, like for example new drivers. Usually it takes the updated files from the VMware repository, but you can also add custom repositories (or depots).
Reading Time: < 1 minuteI had a lot of trouble with one particular “special” VMDK on a ESXi 6.5 system, which did not start after a reboot of the ESXi host. The VM power-on procedure failed with this message: “File system specific implementation of LookupAndOpen[…] failed”. However in the end it just gave me the overall error that it failed to start the machine.
Reading Time: 4 minutesVMware Cloud Foundation (VCF) is VMware’s unified SDDC platform for the hybrid cloud and it’s based on VMware’s compute, storage, and network virtualization technologies to deliver a native integrated software stack that can be used on-premises for private cloud deployment or run as a service from the public cloud with consistent and simple operations. The core components of VMware Cloud Foundation are VMware vSphere (for the compute part), vSAN (for the storage part), and NSX DataCenter (in version -v or -T, for the network and security part).
Reading Time: 6 minutesI’ve already wrote about the different reasons on Why upgrade to VMware vSphere 6.7 (or why not), but I’ve not yet provide tips and hints on how perform the upgrade process. If you are lucky enough to have a full VMware Cloud Foundation (VCF) stack, then you don’t have much problem… the VCF Lifecycle Manager that can make your life easier (see also Simplify VMware’s products update/upgrade). Otherwise you need to plan this activity carefully and perform different tasks, some manual, some automatic.
Reading Time: 6 minutesVMware NSX-T Data Center is the next generation product that provides a scalable network virtualization and micro-segmentation platform for multi-hypervisor environments, container deployments, and native workloads. Under this umbrella there are two main products: NSX-v and NSX-T. Also if NSX-T has not yet become features parity with NSX-v, it’s becoming clear that, in the future, it will replace the NSX-v product and become the only NSX Data Center line.
Reading Time: 3 minutesKubernetes (k8s) is an open-source system for automating deployment, scaling, and management of containerized applications and during the last years has become the standard de-facto of large containers management. VMware PKS (launched on August 2017) is a purpose-built product that enables enterprises and service providers to simplify the deployment and operations of Kubernetes clusters. It provides a production-grade Kubernetes distribution with deep NSX-T integration for advanced networking, a built-in private registry with enterprise security features and full life cycle management support of the clusters.
