How to Install VMware Tools in Ubuntu 13.04 (Raring Ringtail)

Linux, Video Tutorials

VMware Tools is an optional, free set of drivers and utilities that enhances both the performance of a virtual machine’s guest operating system and interaction between the guest and the host. From time to time I find clients have not installed the VMware tools in their virtual machine’s (VM) operating system. I find it more often in Linux VMs than Windows. Installing VMware Tools in the guest operating system is vital. Although the guest operating system can run without VMware Tools, you lose important functionality and convenience.

Installing Red Hat Enterprise Linux 6.4 (RHEL 6.4) in VMware Workstation 9.0.2

Linux, Video Tutorials

Red Hat Enterprise Linux (RHEL) is a Linux-based operating system from Red Hat designed for businesses. RHEL can work on desktops, on servers, in hypervisors or in the cloud.

Introducing VMFS 5: What you need to know in a nutshell – vSphere 5

VMware

It?s new, and it?s good :) VMFS-5 increases limits (without increasing extents) to 64TB. It enables 2TB+ RDMs. It uses a common allocation size of 1MB. It increases the small block allocations available for total use. It is a dependency for SCSI UNMAP It uses the VAAI HW accelerated locking more extensively. Be aware: While it can non-disruptively be upgraded from VMFS-3 to VMFS-5 - if it were my environment - I would tend to create new datastores and svmotion.

How to Deploy Windows Server 2008 Read Only Domain Controller (RODC)

Video Tutorials, Windows Server

Read-Only Domain Controller (RODC) is an additional domain controller for a domain that hosts read-only partitions of the Active Directory database. An RODC is designed primarily to be deployed in a branch office environment. Branch offices typically have relatively few users, poor physical security, relatively poor network bandwidth to a hub site, and little local IT knowledge. RODC is primarily aimed at providing additional security on an Active Directory Database for a server that is not physically secured. In this video we'll deploy Windows Server 2008 Read Only Domain Controller (RODC).

Installing CentOS 6.4 in VMware Workstation 9.0.2

Linux, Video Tutorials, Workstation

What is CentOS? CentOS, which stands for the Community Enterprise Operating System, is a distribution of the Linux operating system based on Red Hat Enterprise Linux (RHEL). It is currently the most popular Linux distribution for web servers. CentOS uses the Red Hat source code base to create a product similar to RHEL. Unlike RHEL however, CentOS does not require a paid subscription. In January 2014, Red Hat announced that it would sponsor the CentOS project. As the result of these changes, ownership of CentOS trademarks was transferred to Red Hat. Related Video: https://www.youtube.com/watch?v=pO7iZbuTYJU
