• How do you enable centralized vCenter logging?

  Centralize vCenter log files with vRealize Log Insight. Configuration with vSphere is simple and enables the centralization and transmission of event and task logs. Continue Reading

• How do you reconfigure access to a VMkernel port?

  Use ESXi firewall configuration settings and VMkernel ports to control the levels of access that different services, such as Secure Shell, have to your management network. Continue Reading

• How do you prevent host isolation during network maintenance?

  The host in a VMware high availability cluster uses a heartbeat network that can incorrectly report host isolation. Reconfigure your settings to prevent this during maintenance. Continue Reading

• Set up a vSAN 2-node cluster for small or remote deployments

  Use a vSAN 2-node cluster for small and branch office deployments. Use a cluster with two physical hosts for data storage and a third server as a witness appliance. Continue Reading

• VMware microsegmentation in NSX trumps going sans SDN

  Software-defined networking can help plug security holes and minimize microsegmentation management tasks; it's worth a look for companies that haven't virtualized their networks yet. Continue Reading

• Keep tabs on your data center for VM sprawl management

  Having too many unnecessary VMs on a network strains CPU, memory and storage resources. It's up to the virtualization administrator to create a VM sprawl management plan.Continue Reading

• Control VM sprawl with the right management tools

  Virtualization sprawl is the result of careless resource provisioning, and it can waste valuable computing resources, but, with the right tactics, it's possible to control VM sprawl.Continue Reading

• How do you upgrade VM hardware, and what are the benefits?

  You can set up your infrastructure to better take advantage of new technology in just a few steps. Perform a VM version upgrade to get the most out of what you have.Continue Reading

• Configure ESXi Autostart to streamline host patching

  Enabling ESXi Autostart can save you time and effort when managing VMs. Learn how to configure Autostart VMs in VMware host settings to make patching hosts easier.Continue Reading

• Use ESXi host logs to troubleshoot an unexpected reboot

  When your ESXi host abruptly reboots, you can use logs to track the potential causes, whether they be planned, environmental or hardware-related.Continue Reading

• Recover an ESXi root password for stand-alone and vCenter hosts

  A forgotten ESXi root password can stop you in your tracks. Avoid dodgy quick fixes and learn the proper way to recover a root password for vCenter-connected and stand-alone hosts.Continue Reading

• How do you use VMware ESXi logs to troubleshoot your host?

  With access to logs, you can troubleshoot your ESXi host and track issues as they crop up. You can access your logs via the console or a web browser with only a few simple steps.Continue Reading

• How can a vSAN-HCI combination complete your VM environment?

  HCI can streamline data centers, but its modular approach poses storage challenges. Use vSAN to complete your virtual environment, and avoid unnecessary work.Continue Reading

• Change VMkernel port MTU size to reduce packet fragmentation

  A high maximum transmission unit size creates fewer frames, which lowers the risk of collisions and reduces overhead. The key is figuring out how high an MTU size is too high.Continue Reading

• VMware uses machine learning algorithms for proactive problem solving

  Machine learning requires massive amounts of data to identify issues before they occur. VMware uses Skyline proactive support technology to more efficiently farm that data.Continue Reading
