Understanding Memory Compression in vSphere 4.1

vSphere 4.1 comes with a new performance-enhancing feature called memory compression. It can give your system a performance boost when it starts running low on RAM. Just like swap memory, memory compression is not equal to real memory but can help to prevent degradation of performance when you're running low on memory. For comparison, memory compression is faster than swap on disk but slower than real memory. --> The rest of the article and explanation is on the blog : http://www.petri.co.il/memory-compression-in-vsphere-4-1.htm

ESXi disk size requirement?

I’ve seen this question passing by a couple of times now and I found myself going through the document to dig up the reference. I thought it would come in handy to document it: Q) What is the disk size requirements for ESXi installable?A) The minimal required disk size is 5GB (Page 24, ESXi Installable and vCenter Server Setup Guide), recommend is 6GB (KB: http://kb.vmware.com/kb/1026500) http://www.yellow-bricks.com/2010/10/27/esxi-disk-size-requirement/

Thinking of upgrading to vSphere 4.1?

Just keep in mind that certain changes from older versions should be identified before upgrading to enable a smooth transition. These are just some pointers for what should be thought about from the outset. As with most new versions of software, there are always simple things that might cause unnecessary pain. The main thing to point out is that if you upgrade your ESX or ESXi hosts to vSphere 4.1 first then you won’t be able to add them to vCenter 4.0.x or older so the best process would be to upgrade vCenter first to 4.1 as this...

ESX 4.1 sera le dernier avec un COS ...

ESX 4.1 is the Last ESX! What Do I Do Now?VMware shipped ESX Server 1.0 way back in 2001. While the word “Server” was lost over time, another bigger thing was not: the Console Operating System (a.k.a. Service Console or COS), a Linux instance that facilitated local management operations. While this administrative environment had an important role early on when centralized management with vCenter Server wasn’t as common as today, it also introduced overhead and made our platform less secure and robust as it could have been without...
