What a week… For me personally of course the announcement of our upcoming book "vSphere Quickstart guide" was a highlight. But that wasn't the only thing that happened this week, VMware acquiring Springsource was probably one of the most discussed topics and of course I added one of the best articles on this acquisition to the top 5. Have fun!
- Steve Kaplan – VMware's got plenty of mojo
Although Kennedy contends that VMware lacks "real innovation", vSphere incorporates remarkable advances in compute, storage, network, security and management. But vSphere is much more than the sum of its 150+ new features – it fulfills the performance, reliability, management and security requirements to establish virtualization as the standard and the foundation of a 100% virtualized data center. - Jason Boche –
vSphere 4 Reference Card now available
Forbes Guthrie has done it again! His wildly successful VI3 reference card is now available in vSphere format. Head over to his site, vReference, and download your copy today. Be sure to thank him for his hard work! I for one appreciate all that he does. Thanks Forbes and I look forward to meeting you in a few weeks. - Bouke Groeneschij – Getting vmware-hostd memory usage
Now we want to be in control and determine ourselves to restart the
hostd process, but we do not run it against all server blindly. We
needed a list first which tell us what servers are running high with
hostd memory usage. Since vmware-hostd is a service console process,
powershell wasn't really an option. So I used plink and dos batch
scripting instead, giving me a perfect .csv list with the current
memory usage on each server. - Chris Wolf- SpringSource: VMware’s well-timed Acquisition
I see the move as astute because SpringSource gives VMware the right platform at the right time. Chris Haddad – with our Application and Platform Strategies Service – detailed how a combined VMware and SpringSource platform will impact application development. Virtualization (i.e., server, client, application, storage, I/O, and network) and cloud are fundamentally changing the way that both server and desktop applications are delivered. Last year I wrote about how this transformational period creates opportunity for Microsoft’s competitors such as Apple. Cloud-based application delivery (both internal and external) is equally disruptive to traditional server application delivery models. What this means is that the time to redefine application delivery and to unseat the incumbents is right now. - Duncan Epping – HA and Slot sizes
Of course we need to know what the slot size for memory and CPU is first. Then we divide the total available CPU resources of a host by the CPU slot size and the total available Memory Resources of a host by the memory slot size. This leaves us with a slot size for both memory and CPU. The most restrictive number is the amount of slots for this host. If you have 25 CPU slots but only 5 memory slots the amount of available slots for this host will be 5.
