Before I’ll report on this major upcoming VMware event, I’d like to inform all ESX Virtualization Blog readers about my recent changes. My life change was programmed and planned. We moved back to France (continental) last month. After 17 years living in Reunion Island (Fr), we decided to discover more countries in Europe and elsewhere. […]
Infrastructure Modeller by Akasia shows you the savings before you migrate to the cloud – check it out
Today I’d like to write about a service from one of our partners which is providing a very cool service. A cloud modeling before migration. They are able to simulate costs based on your on-prem environment and they are neutral (not biased). I’m sure that all major software vendors such as VMware or Microsoft, or cloud […]
VCP-DCV Objective 4.14 Configure Different Network Stacks
One of the last topics we need to cover on the VCP-DCV study guide is a configuration of different networking stacks. You can create a custom TCP/IP stack on a host to forward networking traffic through a custom application. Once you set a TCP/IP stack for the VMkernel adapter, you cannot change it later. If […]
Monitor resources of vCenter Server Appliance and vSphere environment – VCP-DCV Objective 5.2
VMware vCenter Server Appliance (VCSA) has regular updates which bring new features. Not so long ago it was only a black box that you could only monitor with CLI or via console session. Today, VCSA has it’s own management and offers the monitoring of several components like CPU, disks, network, or even services through UI. […]
VCP-DCV Objective 5.7 Plan for upgrading various vSphere components
Upgrades are safe if done right and in the right order. Prior to upgrade you should always backup your vCenter server appliance. This topic isn’t complete without reading other chapters from our VCP-DCV Study Guide here. When studying for the exam, you have to use VMware documentation as our guide isn’t covering ALL, but guiding […]
VCP-DCV Explain shares, limits, and reservations (resource management) – Objective 5.1.1
When you do over-provisioning on ESXi host, on memory, and CPU, you basically need a tool that makes sure that the VMs get the correct amount of resources. Let’s say we have a VM that needs to get 3500MHZ (Reservation) and make sure that another VM for testing never gets more than 1000MHZ (Limit). The […]
vSphere 7 ESXi Secure Boot Options
ESXi provides the option of using UEFI Secure Boot. UEFI Secure Boot is a mechanism that makes sure that only trusted code is loaded by the EFI firmware. Then only the ESXi OS is loaded and you get finally to the UI where you can log in. When Secure Boot is enabled, the UEFI firmware […]
VCP-DCV Objective 7.11.2 – Describe ESXi Updates
After upgrading to vCenter Server 7.0, you can use Lifecycle Manager to upgrade ESXi hosts and virtual machines. Within the lifecycle manager, there you can use the Update Planner to examine available vCenter Server updates and upgrades. You can generate interoperability reports for installed VMware products within your environment as well. You can also compare […]
VCP-DCV 2021 Objective 4.11 – Configure vSphere certificates
vSphere certificates you can basically stick to the defaults when it comes to provision vCenter server components and ESXi hosts with certificates. The certificates are managed and issued by VMware Certificate Authority (VMCA). You have another option to use custom certificates stored in the VMware Endpoint Certificate Store (VECS). vCenter Server supports custom certificates generated […]
VCP-DCV 2021 Objective 2.3 – Identify migration options
VMware vSphere can do different types of migrations of VMs. In this post which is part of the free Study guide for VCP-DCV Certification exam, we’ll be talking and Identify migration options under vSphere. You can migrate virtual machines (VMs) from one compute resource or storage location to another while the virtual machine is stopped […]
