This is useful when you want to host multiple websites with different purposes or for different clients on a single server. Enabling SSL on your website is important for security and to establish trust with your users. SSL ... Read More

RAID stands for Redundant Array of Inexpensive Disks. It is a data storage technique that allows users to combine multiple disks into a single logical unit to provide performance, reliability, and storage capacity. RAID 0 (Stripe) is one of the RAID levels that uses striping to write data across multiple disks. In this article, we will learn how to create RAID 0 on two devices using the mdadm tool in Linux. What is RAID 0? RAID 0, also known as striping, is a RAID level that combines multiple disks into a single logical unit. Data is divided and written ... Read More

RAID (Redundant Array of Inexpensive Disks) is a technology that combines multiple disks into a single logical unit for performance, redundancy, or both. RAID 5 is a type of RAID that uses striping with distributed parity to provide both performance and redundancy. In this tutorial, we will show you how to create a RAID 5 array in Linux. Before we start, let's first understand the concept of striping with distributed parity. What is Striping with Distributed Parity?
