vSphere 4.1 released

Well after the not so quiet news about vSphere 4.1 being due for release, shock and horror it’s been released. As there are a multitude of people that have had the the opportunity to play and use the RC for a while and therefore have a better understanding of all the new technologies and features I thought I would just summarise all the postings that explained all the new features to me and interested me as there’s sadly a very large number of the RC-enabled bloggers that have almost just cut and pasted the same information from a What’s New news release/PowerPoint slide deck into their blog posts.

  • Eric Siebert has posted I think the best resource and posting of all the features and all the changes since the last release/s. It has all the detail you could need and it is being constantly updated by him on the new features. This is what I hoped many more of the top RC-bloggers to have done.
  • Eric Sloof has posted all about the KB articles pertaining to this release. These links are always a great way of learning the best practices for installing and or upgrading your environment to the latest level and warning of possible problems. This is a page I have set a bookmark to for future reference.
  • Eric has also posted a load of amazing postings all about the Emergence of 10 GigE ,improved vMotion speeds , Memory Enhancements – Compression. I would highly recommend reading these as he’s given some really great details all about these features.
  • Gabrie van Zanten has done a brilliant posting with all of the features and comparisons of the varying versions you can choose and the features they contain. As well as all the new features in the new release.
  • One of the big changes in vSphere 4.1 is licensing has changed for a number of the management tools/products that come with the suite. Erik Scholten has detailed this in his blog posting here
  • Luc Dekens has posted all about the new PowerCLI cmdlets with PowerCLI 4.1 and what the cmdlets can do for you. The open source software for vSphere PowerCLI 4.1 is available from here and here
  • Maish Saidel-Keesing has posted up screenshots of the PowerPoint presentation a lot of people are reposting the information of the new release from but has done the New features and enhancements for ESXi 4.1 side of it so it is an interesting read to see how VMware believe ESXi is good enough to push all their current full ESX customers to ESXi. I still can’t see it happening and no matter what anyone says I think they’ll make plans to accommodate people who don’t want to change as not everyone can change over their whole environments in a short space of time and I know a few people who are still to upgrade to vSphere and they are all very large corporations.
  • On the training side Scott Vessey has posted that there will be a new Install Configure Manage course for vSphere 4.1. I asked if the new VCAP and the VCP4 exams will now be related to 4 Update 2 and 4.1 on twitter and Scott replied with loads of information as per usual.

  • Keep an eye on Scott’s blog for all the latest information about all the training courses and exams here

Well that’s all the best bits and information I’ve come across, I’m sure there will loads of postings in the coming weeks and months about it all. I’m already downloading it to test out in my lab. Hopefully they don’t bring out 4.1 Update 1 too quickly as it feels as soon as I’ve patched and upgraded all my hosts a new update or version comes out.

*UPDATE* Eric Siebert has done an INSANE list off all the links and news for 4.1 on his site here. 🙂 Killed my list by miles.

All things virtual X

The past two weeks have brought some really great news and views in the virtualisation arena.

On the 6th of this month i was able to attend the London VMware User Group for the second time. There were some very interesting discussions and presentations. I wrote up a blog posting on the day here if you’re interested. I would firmly recommend anyone interested in this field to find out where and when your local VMUG is happening and get your spot as conversing with fellow virtualisation administrators can increase your knowledge on new things very quickly and easily. Hopefully the content from the user group will be uploaded to the normal location soon.

If you somehow haven’t heard about it yet the features due to be in vSphere 4.1 were “leaked” a few weeks back now. There are quite a few new features I’d welcome with open arms like support for up to 4 vMotion concurrent live migrations in 1GbE networks and up to 8 concurrent live migrations in 10GbE networks and Support for 8GB Fibre Channel HBAs. As the article says there is no guarantee that the features will actually be in the public release. I say “leaked” as personally i think if they didn’t want it getting out it wouldn’t have got out, i think it’s just a perfect way of judging people reactions to the features mentioned and see see how they can make some minor changes before making it available.

One of the people i got to meet in person at the London VMUG was Ricky El-Qasem of Veeam. As I’ve said numerous times before I’m hoping to better my powershell/PowerCLI skills as at the moment they are terribly basic and therefore are in dire need of bettering to enable me to script portions of my work to save me time and hopefully prepare me for the lack of the COS in possibly vSphere 4.1. Ricky has posted a few blogs all about his journey in learning PowerCLI in PowerCLI lessons and the resources he has used to grow his skills. Embarrassingly i still haven’t forced myself the time to sit down and get through all of the posts but after speed reading most it it looks like it is going to be highly beneficial to me when I stop being lazy and start working at it.

EMC world that ran from the 10th to the 13th of May brought some really interesting news.The most interesting to me was the announcement of the VPLEX which will enable “VM teleportation”. I won’t try and describe what the technology does and enables you as Chad Sakac has done a brilliant blog posting all about it and what it enables you to do. I can’t wait to be able to play with VPLEX once it’s available. There is also a very interesting KB article all about Enabling long distance vMotion with EMC VPLEX here

Last week the Call for Papers Public Voting opened up for VMworld 2010. Quite a few of the guys I’m friendly with on twitter have made the cut and their sessions have been made available to be voted on. I’m quite amazed by the massive amount of cloud sessions that have been selected. I’m really hoping that VMworld isn’t overshadowed(pun kind of intended) by all the cloud talk. I’ve cast my votes some of which were for fellow UK virtualisation friends and others obviously for ones i really want to be able to see/attend. If you’re like me and gain loads of information and help from Alan Renouf’s PowerCLI scripts then I would recommend a vote for his and Luc Dekens’ “ PowerCLI is for administrators! “ session. There are also sessions by Simon Seagrave of TechHead fame with “Building A Successful vSphere Lab” and “Network Segmentation in a Virtualized Environment ñ Best Practices and Approaches” by Nicholas Weaver of Nickapedia fame to name but a few. So go vote if you’re going to make it to either of the events and hopefully we’ll have loads of really great sessions. If you haven’t registered to attend VMworld then you can still register and get a $250 or €200 early bird discount.
