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.

The Dell PowerFlex Storage Data Client (SDC) lets a Windows server access block volumes presented by a PowerFlex cluster. This guide covers the manual SDC installation, verifies the connection to the MDM cluster, and shows how to map and prepare a PowerFlex volume for use in Windows Disk Management. The examples come from a nested lab using Windows Server 2022 Standard and PowerFlex 4.5.2. Dell’s support matrix lists Windows Server 2022 for the SDC with PowerFlex 4.5.2, but always confirm the exact SDC package, Windows build, and any matrix footnotes for your deployment before using the procedure in production.

This guide walks through expanding an existing Dell PowerFlex block volume and making the additional capacity available to an ext4 filesystem on a Linux Storage Data Client (SDC). The example uses PowerFlex 4.5.2 in a nested lab environment. The volume is already mapped to the Linux SDC and contains a GPT partition with an ext4 filesystem. Resizing happens at three separate layers: increase the PowerFlex volume’s capacity, extend the partition so it can use the added space, and then grow the ext4 filesystem. Increasing the volume alone does not expand the partition or filesystem. This procedure demonstrates a 64 GB…

A PowerFlex volume can be mapped to a Linux Storage Data Client (SDC) and mounted for applications to use. However, a manual mount does not automatically return after a server reboot. This guide shows how to configure /etc/fstab so a PowerFlex filesystem is mounted during startup, using the persistent device path supplied by PowerFlex and the appropriate systemd ordering options. The example uses a nested PowerFlex 4.5.2 lab with an Ubuntu-based Linux SDC. Device identifiers, mount points, filesystem types, and service names vary by environment. Confirm the exact operating-system and PowerFlex combination in Dell’s current support matrix before applying the…

Adding and Mapping a new Volume to a Linux SDC shows how to add a volume using the PowerFlex Manager interface and how to map it to a Linux SDC. Our PowerFlex cluster is running on a lab (nested environment). The PowerFlex version is 4.5.2, and our Linux SDC is CentOS-based. Important Notes: that mapping exposes the volume to the selected host as a block device; it does not create a partition, filesystem, or mount point. The Linux steps that follow are separate and must target the correct device! Dell’s PowerFlex 4.5.x guidance says /dev/sciniX names are not guaranteed to…

This guide shows how to assign a friendly name to a Dell PowerFlex Storage Data Client (SDC) by using the PowerFlex command-line interface (SCLI). The change updates the name associated with the SDC in PowerFlex; it does not rename the ESXi host itself or change its DNS and vSphere inventory names. The examples use two ESXi SDCs in a lab. Replace the GUIDs, IP addresses, and names with values from your environment. If you still need to install the client on an ESXi host, see Connecting VMware ESXi to PowerFlex: A Step-by-Step SDC Installation Guide. For an overview of PowerFlex…

Expanding the PowerFlex Cluster with New Disks shows how to add new disks to current SDS devices.Our PowerFlex cluster is running on a nested environment. So, all steps demonstrated here are not in a production environment. The PowerFlex cluster is 4.5.2, and all nodes are CentOS-based! If you are new to PowerFlex, start with this overview of PowerFlex architecture and its core components, including the role of SDS nodes and storage pools. For a related walkthrough of a nested PowerFlex 4.5.2 deployment, see the PowerFlex cluster deployment guide. Currently, which disks are used on each SDS? 1- Access the MDM…
