precision time protocol (PTP) with leap second

percision Time protocol (PTP) is new time keeping protocol enables network device into the timing measurements.

windows server 2019 even introduces supports for leap second
(occasional 1-second additions to UTC to adjust as earths  rotation slows) increases accuracy compliance, and traceability.

Improved Storage Spaces Direct

1. Storage spaces Direct is Microsoft's software defined solution for HVL(Hyper-converged infrastructure)deployments.

2. it allows making use of local storage in each windows server and aggregating the storage together for a distributed storage system that can be used for virtual machines.

Faster sdn (software-Defined Networking) gateways

windows server 2019 provides leaps and bounds better performance  for SDN gateways.

it boasts improvements up to 3x for GRE tunnels and IPSec site-to-site VPN.

Encrypted Subnets/Virtual Network (Vnet) Encryption

.Virtual network encryption Provides the ability for the virtual  network traffic to be encrypted between Vims that communicate with each other within subnets.

HGS(Host Guardian services) offline Mode for shielded VMs

Another new feature with windows server 2019 is that ability to have offline mode for shielded VMs.

offline mode allows shielded VNs to turn on when HGS cannot be reached.

server core features on demand

Features on Demand (FOD) significantly improve the app compatibility of windows server core by including a set of binaries and packages from Windows server with Desktop without adding any of the windows server Desktop GUI

Nano Server Role Changes

windows server 2016 included a new server role know as Nano server  which was primarily a headless OS  meant for use as a host OS  for Hyper-V

The Nano Server in windows 2016 can be installed on bare metal (type 1 Hypervisor).

The windows server 2019 Nano server role can be used only with containers' rather than bare meta

Crontab in linux- Examples and Command

A cron job in Linux is a time-based job scheduler. It is a utility that allows you to schedule and automate the execution of scripts, commands, or programs at specific intervals or at predetermined times. Cron jobs are commonly used in Linux and other Unix-like operating systems to automate repetitive tasks, such as system maintenance, log rotation, backups, and periodic data processing. The cron service is responsible for running these scheduled tasks. It reads a configuration file called the "crontab" (short for cron table) to determine when and which commands to execute. Each user on a Linux system can have their own crontab file, which lists the cron jobs specific to that user The crontab file uses a specific format to define the schedule of a cron job. It consists of six fields that specify the timing of the job: scss * * * * * command_to_be_executed | | | | | | | | | +----- Day of the Week ( 0 - 7 ) (Sunday = 0 or 7 ) | | | +------- Month ( 1 - 12 ) | | +--

How TO Manage Groups Ad User on linux

Linux Admin - User Managemen When discussing user management, we have three important terms to understand − Users   Groups Permissions We have already discussed in-depth permissions as applied to files and folders. In this chapter, let's discuss about users and groups. CentOS Users In CentOS, there are two types accounts –  System accounts − Used for a daemon or other piece of software .   Interactive accounts − Usually assigned to a user for accessing system resources . The main difference between the two user types is − System accounts are used by daemons to access files and directories. These will usually be disallowed from interactive login via shell or physical console login .. Interactive accounts are used by end-users to access computing resources from either a shell or physical console login. With this basic understanding of users, let's now create a new user for Bob Jones in the Accounting Department. A new user is added with the adduser command. Following

User quota in Linux step by step

  Linux Admin – Quota Management As a Linux administrator, quota management is an important aspect of managing file systems and controlling disk usage by users. Quotas allow you to set limits on the amount of disk space a user or a group can consume. Here's a general guide on how to manage quotas in Linux:                Enabling Quota Management in C Linux is basically a 4 step process – Step 1  − Enable quota management for groups and users in /etc/fstab. Step 2  − Remount the filesystem. Step 3  − Create Quota database and generate disk usage table. Step 4  − Assign quota policies. Enable Quota Management in /etc/fstab First, we want to backup our /etc/fstab filen − [root@localhost ~]#   cp -r /etc/fstab ./ We now have a copy of our  known working  /etc/fstab in the current working directory. We made the following changes in the options section of  /etc/fstab  for the volume or Label to where quotas are to be applied for users and groups. usrquota grpquota  As you can see, we

Why use vSAN in VMware?

 VMware vSAN, which stands for VMware Virtual SAN, is a software-defined storage solution offered by VMware. It is a component of VMware's vSphere virtualization platform and is designed to provide highly scalable, high-performance shared storage for virtual machines (VMs) in a vSphere environment. vSAN allows you to pool together the direct-attached storage devices (such as hard drives or solid-state drives) from multiple servers in a vSphere cluster and create a distributed storage infrastructure. By aggregating the storage resources from these servers, vSAN creates a shared storage pool that can be utilized by VMs running on those servers. Key features and benefits of VMware vSAN include: Hyperconverged Infrastructure (HCI): vSAN is a key component of VMware's HCI solution. It combines compute, storage, and virtualization resources into a single software-defined platform, simplifying data center operations and reducing hardware costs. Highly scalable and elastic : vSAN a
