Been really busy today with the kids but did manage to get the top 5 ready for you guys…. Read it!
- Thomas Mackay – Understanding ESX/ESXi Equivalency…Are we there yet?
It is public knowledge that ESX is evolving to a pure ESXi model in the future release cycles of the product, though exact timelines are still under NDA. Convergence to a “console-less” ESX provides a number of benefits to our customers, with which many of you are, by now, well acquainted . It reduces the overall footprint that requires patching (see below) as well as removes the dependency on the vestigial RHEL-based Console Operating System, and sets the stage for future enhancements and technologies yet to be introduced. (Those who are under NDA might know to what I am referring! - Thakala(vReality) – VMware Data Recovery 1.2 Linux file level restore client
I have successfully tested it on 64-bit CentOS 5.5, and because so many versions of Ubuntu are listed I’d guess that FLR client works on any recent Debian releases also, just make sure it has support for FUSE 2.5 or later. If you have custom kernel make sure you have all FUSE dependencies compiled in. Note that even though your Linux distribution may be 64-bit version, 32-bit version of FUSE is required. Note the absence of any SuSE or Novell SLES distrubtions from tested and supported list, not that FLR client won’t work on them though, I am sure it will. - Jon Owings – All out of HA Slots
As you can see here the slot size is rather giant. We have the largest CPU and Memory reservation plus some overhead (for simplicity) and that blows the size of the slot way up. I didn’t set the reservation, but surely they were there. 8GB of reserved memory. 4000MHz of CPU. Ouch. Where did that come from? It followed the VM from the old host to the new one. One of the reasons I was there was to setup a new cluster since the older ones were performing so slow on the local storage. It seems like someone tried to help some critical VM’s along the way by adding the reservations. I removed the reservations and had plenty of slots as you see below. - Massimo Re Ferrre – Cloud and the New IT Pillars
In my previous IT life I was in the business of trying to homogenize heterogeneous virtualization platforms under a single management umbrella so I have to (strongly) agree with my colleague’s statement. In fact, these pillars are very different in the way you manage them. This is true not only from a technology perspective but also, and even more so, from a process perspective. For example, the process to request a partition on a legacy Unix system may be totally different than the process required to instantiate a new physical server, which in turn is totally different than the process to request a new vSphere virtual machine. To complicate things more, the Cloud pillar, by very definition, doesn’t require any process whatsoever to instantiate a new workload from the self-service portal. - Duncan Epping – vSphere 4 U2 and recovering from HA Split Brain
I had never noticed this until I was having a discussion around this feature with one of my colleagues. I asked our HA Product Manager and one of our developers and it appears that this mysteriously has slipped. As I personally believe that this is a very important feature of HA I wanted to rehash some of the info stated in that article. I did rewrite it slightly though…
