Increase Disk Space In Windows Server 2016

This post will cover how to increase the disk space for a Windows Server 2016 virtual machine running in VMware, however the steps apply to any virtualization solution.

The server can stay online while the disk space is upgraded with this method which is ideal for most production servers, there’s no need to perform a system reboot.

Gzip vs Bzip2 vs XZ Performance Comparison

Compression

Gzip, Bzip2 and XZ are all popular compression tools used in UNIX based operating systems, but which should you use? Here we are going to benchmark and compare them against each other to get an idea of the trade off between the level of compression and time taken to achieve it.

For further information on how to use gzip, bzip2 or xz see our guides below:

Free up disk space in Citrix XenServer

A Citrix XenServer dom0 currently runs with a 4GB root partition which is pretty small by today’s standards. A small amount of usable storage space can be quite easy to quickly fill. It is therefore important that dom0 has free space in order for it to operate correctly. Here we will cover some different methods that can be used to free up disk space within XenServer.
