Last week I upgraded a Virtual Center server from Win2003 & MSSQL 2000 (32-bit) to Win2008 & MSSQL 2005 (64-bit). During the installation of vCenter it asked for a 32-bit ODBC even though all the new systems was running 64-bit. After a some time on Google i found that Windows 64-bit also includes a 32-bit […]

Have you ever needed to document how secure your ESX servers are. If the answer is yes then take a look at these free fools (Compliance Checkers) from ConfigureSoft.com. http://www.configuresoft.com/compliance-checker.aspx If the answer is no I would sugest you took a look at the tools anyway…… Compliance Checker for VMware ESX, checks the compliance of […]

VMware have released a demo on YouTube that shows a “must have” for PowerShell users who automate and manage vSphere and vCenter through PowerShell. The project is named “Onyx” and works like a middelware between the vCenter Client and the vCenter Server. Onyx is unfortunately still in a private beta and therefore not acceble to […]
