Is It A Bird? Is It A Plane? No, It’s….The Cloud!

Mar 2nd, 2010 | By Simon Long | Category: Cloud Computing, Featured

Why, oh why, oh why, has every man and his dog started calling everything Cloud? Cloud Hosting, Cloud Apps, Cloud Services? Is it me, or was it only 6 months ago that these were called Virtual Hosting, Web Apps, Web Services? What’s changed?



Do I Upgrade to VMware Virtual Hardware Version 7?

Feb 10th, 2010 | By Simon Long | Category: Server Virtualization

I am in the process of planning for a large infrastructure upgrade from ESX3.5 to vSphere 4. As part of the planning I've been looking at Virtual Machine Virtual Hardware Versions. Currently all VM's are running Version 4, but as we migrate to ESX4 we will have the option to upgrade to Version 7.

VMware Hot-Add Memory/CPU Support

Dec 9th, 2009 | By Simon Long | Category: Server Virtualization

I've been asked to take a look into the Hot-Add Memory and CPU features which are available with vSphere 4. The concept seems pretty useful and straight forward, but what isn't is the list of Operating Systems that support these features. There doesn't seem to be a definitive list. Either that, or I should have [...]

Have you ever wanted to check your Network throughput between your ESX Hosts? or even between VM’s? Well I needed to do this, and I couldn’t find any straight forward how-to’s.

Allocated Unlimited Memory…Or Have You?

Nov 2nd, 2009 | By Simon Long | Category: Server Virtualization

After doing a range of Memory testing and analysis on a group of Vmware Virtual Machines, the subject of the “Unlimited” Memory/CPU tick box was brought up.
When Resource Allocation’s are setup on a VM there is the option of selecting an Unlimited Limit. It seems as though some people misunderstand exactly what that tick box [...]

VMware vCenter 4 minimum RAM requirement, is it 2GB or 3GB?

Sep 14th, 2009 | By Simon Long | Category: Server Virtualization

According to the VMware document: ESX and vCenter Server Installation Guide page 16, it clearly states;
Memory – 3GB RAM. Memory requirements might be higher if the database [...]
