RedHat Enterprise Linux 7t Introduction

I'm here to list some of the areas where programmers might be more interested.

1. System Architecture

RedHat Enterprise Linux 7.0 supports more CPUs, cores and memory. Only 64-bit hardware supports Redhat Enterprise Linux 7.0 installation.

2. Installation and boot tools

RedHat Enterprise Linux 7.0 has redesigned and improved the installer Anaconda to improve the installation process for RedHat Enterprise Linux 7.0. In addition, it uses the new boot loader GRUB2, which is more robust, more convenient, and more powerful than its predecessor, Grub. In addition to the Linux file system, GRUB2 also supports non-Linux file systems such as Apple's extended tiered file system (hfs+) and Microsoft's NTFS file system.

3. xfs File System

The default file system used in Redhat Enterprise Linux 7.0, which is currently installed with Anaconda, is XFS, which replaces the fourth-generation extended file System (EXT4) used in Redhat Enterprise Linux 6. The Ext4 and Btrfs (b-tree) file systems are available as an alternative to XFS. XFS is a highly scalable, high-performance file system originally designed by Silicon Graphics, Inc. to support up to 16 bytes (about 16 million TB) of file systems, up to 8 bytes (about 8 million TB) and a directory structure containing tens of millions of purposes. XFS supports metadata journaling, which speeds up the recovery of crashes.
