Today we bring you an interesting article that explains how to clean up snapshot files to free disk space in VMware server. This tip may result very useful for those who are looking for a way to recover some virtual hard disk space and are frustrated with how much space the virtual machines demand.
In some cases, when analyzing the storage needs for a VDI platform we look at saving disk space when using template-based or non-persistent desktops. Nevertheless, it is necessary to bear in mind that all the I/O operations on disc in a standard job platform are made on local discs located in each post.
In a VDI environment, all these I/O operations take place concurrently on shared storage. Tasks such as updates of OS patches, antivirus, user logins scans… produce a large amount of concurrent I/O operations that are referred to as “storms”. These storms produce a deterioration in the performance of the storage because these I/O operations are accumulated in queues and this, obviously, causes an irregular performance of the virtual desktops.
At the end of a class, each student has changed many aspects of virtual machines (VM). In order to prepare them for the next class, it is important to be able to return them to its original state as soon as possible. The Logical Volume Manager snapshots are useful in these cases.
The Logical Volume Manager (LVM) is a method that has been used successfully on Linux for many years and managing storage in a flexible way. Instead of working with fixed storage allocation units, LVM work with versatile volumes that can be extended or reduced very easily. These volumes offer also other benefits, like the snapshots.
Online learning through virtual classrooms is becoming increasingly widespread. For companies that wish to join this trend, virtualization with KVM is a good option, because that enables you to deliver a remote high-quality education at a very affordable price. In this article, we explain the hardware and memory requirements to set up an environment based on KVM to offer online courses. Our VDI multiplatform connection broker for Windows and Linux, UDS Enterprise, is fully compatible with KVM.
Considering the current development of hardware, it is not necessary to pay a lot of money for hardware that work properly. You only should look for the most suitable according to quality and price, like Intel NUC.
A very common mistake when you dimension the necessary platform to host your VDI environment is to base the sizing calculations according to the current resources.
When you purchase hardware PC, these equipments are essentially acquired according to market standards. In most cases, the resources offered by these PCs are underused, so you are sizing a VDI platform with resources that won’t be necessary, with the consequent costs increase.
In other cases, resource calculations are performed without taking into account the future growth of the platform of users, having resource contention issues in a short period of time.
