Infrastructure Engineer with hands-on experience in virtualization, Linux, Windows Server, and enterprise infrastructure troubleshooting. I work with real-world infrastructure environments and technical labs, focusing on diagnosing problems, understanding root causes, and documenting practical solutions. DPC Virtual Tips was created to share hands-on troubleshooting guides, lab experiences, technical procedures, and lessons learned while working with technologies such as VMware, Linux, HPC/Slurm, networking, storage, and infrastructure automation with Python.
This guide describes a lab deployment of the Dell PowerFlex Management Platform (PFMP) on Linux. It covers the temporary installer VM, the configuration file, the three-node management cluster, and initial access to the web interface. The original lab was built with a PFMP2-4.5.2.0-173.tgz installer archive and a CentOS 9-based installer VM. Treat those as the versions used in that lab, not as a current support recommendation. Dell’s PowerFlex 4.5.x guide lists different operating systems for Linux management deployment, and Dell’s later guide pairs PowerFlex 4.5.2 and later with PowerFlex Manager 4.6.x. Before reproducing these steps, confirm the supported PowerFlex core,…
This hands-on lab shows how to deploy a nested Dell PowerFlex 3.6.4 cluster on VMware vSphere. The environment uses virtual machines to model PowerFlex storage nodes, a five-node MDM cluster, VLAN-separated traffic, a PowerFlex Gateway, a Presentation Server, and Windows and ESXi Storage Data Clients (SDCs). Lab warning: This is a nested learning environment. It is intended to demonstrate PowerFlex concepts and deployment workflows, not to provide a production design. Virtualizing storage nodes on a single physical ESXi host introduces shared failure domains and does not reproduce the performance, availability, or hardware-validation characteristics of a production PowerFlex system. If you…
Introducing the Dell PowerFlex Solution provides an overview of Dell PowerFlex, a software-defined storage platform designed for modern data center environments. The solution combines storage and compute resources into a flexible architecture focused on performance, scalability, and operational efficiency. In this article, we will explore the main components that build the PowerFlex software architecture, including Meta Data Manager (MDM), Storage Data Server (SDS), Storage Data Client (SDC), File Services Node (FSN), and other essential services that enable the platform capabilities. First and foremost, what is Dell PowerFlex? Dell PowerFlex is a software-defined storage platform that combines storage and compute resources…
NSX Manager maintains important management-plane configuration for an NSX-T Data Center environment, so a recoverable backup should be part of the operational plan. VMware snapshots are not a supported backup or rollback method for NSX Manager or Edge appliances. Use the built-in NSX backup workflow and send backups to a supported remote SFTP server instead. This guide walks through configuring the SFTP destination, verifying its SSH fingerprint, running a manual backup, and enabling recurring backups in the NSX Manager interface. The lab uses TrueNAS as the SFTP destination. Menu names, supported SFTP software, and schedule options can vary by NSX…
