XenApp 6 – CPU Usage Management & Virtual memory optimization

En este documento veremos dos formas de optimizar nuestras granjas de XenApp mediante un par de directivas de Citrix, la Administración del uso de CPU e implementando la optimización de la memoria virtual. Con la primera administraremos el uso de la CPU donde podremos administrar el % de uso compartido por usuario para evitar que los consumos altos de CPU afecten al resto de usuarios consiguiendo además una mayor capacidad por servidor. Optimizando la memoria virtual mejoraremos el uso compartido de ficheros DLL entre las aplicaciones que se ejecutan, ahorrando ambas memorias (virtual y real).

Backing up VMware ESXi configuration

Once our hosts have been configured, it is advisable to keep a backup copy of their configuration, an easy way to back up the entire configuration of an ESXi host is by using the VMware vMA appliance or by using the VMware vSphere CLI (vCLI). Once we have the backup, we can restore it if necessary in a simple way, we will also see another command to reset ESXi hosts to factory values.

Using VMware Compliance Checker

The past 19 April, VMware introduced VMware Compliance Checker, a free VMware tool (written in Java) that will help us verify the security of our VMware hosts (ESX or ESXi), recommended as one of the best practices to be carried out in our environment in order to secure or detect problems, obtaining a detailed report of the recommendations to be made on each host.

Using VMware Go

Today we can see on the Shavlik website that it has been acquired by VMware, so I present to you (for those who may not know) VMware Go, that it is a tool developed by both companies in collaboration, it is free and online, that allows limited management of our VMware virtual infrastructure, it is a tool designed for new and small clients who are entering the new world of VMware and want to start with simple management. This tool has its free version (which is what we will see in this document) and the paid VMware Go Pro version which will address the shortcomings of its free version.
