Securing SSH access using key-based authentication is an essential practice for enhancing the security of Linux servers. This method is more secure and convenient than password-based authentication. Here’s a step-by-step guide: Step 1: Generate SSH Key Pair On your local machine, open a terminal and generate an SSH key pair: bash ssh-keygen -t rsa -b […]
Troubleshooting frequent NIC (Network Interface Card) failures in servers is critical to maintaining a reliable IT infrastructure. Below are steps you can follow to identify and resolve the issue: 1. Gather Information Document the Issue: Note the frequency, nature, and patterns of NIC failures (e.g., specific times, workloads, or environmental conditions). Check Logs: Review system […]
Configuring iSCSI multipathing is essential for fault tolerance and improved performance in your storage environment. Multipathing allows an iSCSI initiator to use multiple network paths to access storage targets, ensuring high availability and load balancing. Below is a step-by-step guide to configure iSCSI multipathing: Prerequisites iSCSI Storage Array: Ensure your storage array supports multipathing. Multiple […]
Resolving “Out of Memory” (OOM) killer events on Linux servers requires a systematic approach to identify the cause and implement appropriate solutions. Here are the steps and strategies to address OOM issues: 1. Analyze Logs and Identify the Cause Check System Logs: Examine the /var/log/messages or /var/log/syslog file for OOM-related entries. Search for “oom-killer” or […]
Scaling GPU resources for AI training involves several considerations, including hardware, software, workload management, and infrastructure planning. Here are the steps to effectively scale GPU resources: 1. Assess Workload Requirements Understand the Model: Determine the size and complexity of the AI model you’re training. Larger models (e.g., transformer-based models like GPT) require more GPU memory […]
As an IT manager responsible for storage and datacenter operations, troubleshooting disk failures in RAID arrays requires a structured approach to ensure minimal downtime and data integrity. Here’s a step-by-step guide to troubleshoot disk failures in RAID arrays: 1. Verify Symptoms of Disk Failure Alerts: Check for alerts or notifications from the RAID controller, storage […]
