1. How to fix slow VM performance? Where to start troubleshooting? Start: vCenter → VM → Performance tab → isolate resource bottleneck. 2. If ESXi host not responding, what’s next? 3. Management service restart command (ESXi Shell)? # Restart hostd (main management agent)/etc/init.d/hostd restart# Restart vpxa (vCenter agent)/etc/init.d/vpxa restart# Or restart all (use cautiously)services.sh restart

Netflix leverages Apache Kafka as a foundational component of its real-time data infrastructure to power personalized recommendations based on user behavior. Here’s how it works: 1. Real-Time Event Ingestion 2. Kafka as the Central Event Backbone 3. Stream Processing for Real-Time Signals 4. Feeding the Recommendation Engine 5. Feedback Loop and Model Updates 6. Scalability

Uber uses Apache Flink extensively for real-time data processing, including real-time trip tracking, monitoring, analytics, and alerting. While Uber doesn’t publish every internal detail, public talks, engineering blog posts, and conference presentations (e.g., at Flink Forward) reveal key aspects of how Flink powers Uber’s real-time tracking infrastructure. 🚕 Real-Time Trip Tracking at Uber: The Challenge

In HPE OneView, when configuring Blade Servers (typically within HPE BladeSystem enclosures like the c7000), you define networks that serve different purposes depending on their type and configuration. During network creation in HPE OneView, you can assign a network purpose, which determines how the network is used and how it behaves within the infrastructure. The

Configuring NIC (Network Interface Card) Teaming in Windows Server 2019 allows you to combine multiple physical network adapters into a single logical interface for increased bandwidth, load balancing, and fault tolerance. Here’s a step-by-step guide to configure NIC Teaming using both Server Manager (GUI) and PowerShell: ✅ Prerequisites 🖥️ Method 1: Using Server Manager (GUI)

The error “Object exists. An attempt was made to create an object and the object name already existed” when renaming a NIC teaming interface in Windows Server 2019 typically occurs because the new name you’re trying to assign is already in use—either by another network adapter, a previously deleted but not fully cleaned-up virtual adapter,

A Blockchain-Based Storage Platform is a decentralized data storage solution that leverages blockchain technology to securely store, manage, and retrieve files across a distributed network of nodes — instead of relying on centralized servers (like AWS, Google Cloud, or Dropbox). 🔑 Core Concepts 1. Decentralization Files are split into encrypted chunks and distributed across multiple

Managing data on the AWS platform involves leveraging a wide range of services designed for storage, databases, analytics, governance, security, and migration. AWS provides scalable, secure, and highly available solutions to handle structured, semi-structured, and unstructured data across various use cases—from simple file storage to complex data lakes and real-time analytics. Here’s a comprehensive overview

Open source plays a significant and growing role in the design, implementation, and management of Storage Area Networks (SAN) and Network Attached Storage (NAS) systems. While traditional enterprise SAN/NAS solutions have been dominated by proprietary hardware and software from vendors like Dell EMC, NetApp, and HPE, open source alternatives offer flexibility, cost-efficiency, and community-driven innovation.
