How to configure backup on the NSX Manager is an article that explains how to configure automatic backup for the NSX Manager data. Configuring NSX Manager backup is an essential task to protect critical data in an NSX-T Data Center environment. In this guide, we will demonstrate how to configure the built-in backup feature available on NSX Manager and send backup files to an SFTP server. On the NSX-T Data Center, we have a lot of critical components and it is crucial to have a working backup and restore plan. Nowadays, is usually using VMware Snapshots to back up desired…
How to use iperf on ESXi host in an article that explains how to use iperf to test network performance on an ESXi host. Using iperf on an ESXi host is a practical way to measure network performance and validate bandwidth between virtualization components. In this guide, we will demonstrate how to use iperf and iperf3 for network testing scenarios involving ESXi hosts and virtual machines. Basically, what is iperf/iperf3? Based on the website https://iperf.fr/, iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning various parameters related to timing, buffers, and…
Configuring NSX Manager Virtual IP (VIP) is an important step to improve availability and simplify access in an NSX-T Data Center environment. In this guide, we will demonstrate how to configure the built-in Virtual IP feature available on NSX Manager. VMware recommends deploying multiple NSX Manager appliances to provide redundancy and reliability for the NSX-T management plane. When a Virtual IP is configured, administrators can use a single IP address to access the NSX Manager environment instead of connecting to each appliance individually. If you are interested to know more about NSX-T, we wrote an article that introduces the NSX-T…
Increasing the heartbeat timeout in vCenter value can help administrators adjust how long vCenter Server waits before marking an ESXi host as not responding. In this guide, we will show how to configure a new timeout value through vCenter Server advanced settings. Before we get started, we have an article that explains how to debug the heartbeat communication between vCenter and ESXi host. Click HERE to read this article. As a normal communication, each ESXi host inside a vCenter Server sends a UDP heartbeat packet every 10 seconds to the vCenter Server. Basically, when the vCenter receives this packet, it…
