VMworld 2009 Europe Linkage

· ·

Because I haven’t been able to write as much as I would have liked I created this link list. I didn’t include all VMworld articles, just the ones I think are worth reading.

I want to highlight these 4 blogs cause they covered VMworld by far the best in my opinion and deserve some more exposure. Martijn, Simon and Jason wrote a couple of outstanding articles. And Eric Sloof video coverage was top notch again. Here are the links:

VMworld day 2 – Random stuff and Data recovery

· ·

What a day again, and it’s actually not finished cause within a couple of minutes the VMworld Europe 2009 party will start.

The VMTN Experts session was actually, in my opinion, pretty good today. We had way more people coming over that were asking questions or just came over to have a chat with one of the Experts! With the vExperts being announced this morning there was a good atmosphere, even Statler and Waldorf euuuh Boche and Laverick were having fun. For those on twitter and those who have been following the story about VMDougs snuggie, check the video Gabe published, lol.

Now today I did one of the labs together with Eric Sloof, Data Recovery. There are a couple of write-ups on the product for instance this one by VM-Aware so I’m going to write about all the features and scheduling possibilities. One thing I’ve noticed no one writing about is that the Appliance actually uses the hot-add feature which is part of VCB. So basically what happens when you do a backup:

  1. Create a snapshot of disk(s)
  2. Hot add disk(s) to Data Recovery appliance
  3. Create hashes of (hopefully variable) blocks
  4. Read data of changed blocks
  5. Dedupe(using variable chunk sizes) and create hash
  6. Store data
  7. Remove hot add disk(s)
  8. Remove snapshot

    So this is what I’m guessing will happen cause I actually haven’t seen the documentation, but it makes sense in my opinion.. The cool thing about this way of running backups is that doesn’t really matter if you do a full backup or do an incremental/differential it’s always small because of the deduplication. Full backup it is! Although some blogs aren’t sure yet, it will contain file level restore in the future!

    By using the hot add mode it’s a LAN free backup, all I/O is being handled by the ESX Server I/O stack. This will however cause overhead on the ESX Server so you might not want to start 20 backups on the same host. Also keep in mind that the deduplication will be rather CPU intensive so this might also slow down the process if you run multiple backups. The deduplication is “inline” by the way which means that the data will be deduped before it will be written to disk.

    Now there’s more to write about, and especially about the Cloud Plugin that has been demoed today… But I really need to get ready for the VMworld party called “Cloud9” this year! See you guys in a few minutes 🙂 and for those that didn’t come to Cannes, please join John Troyer tonight(wednesday) at the weekly podcast and remind him he’s really missing out on this! 😛

    VMworld Day 1

    · ·

    It’s been chaos all day long yesterday. Some of you might have expected me to do actually live blogging and that’s what I had originally planned indeed. But after being added to the SRM Lab and last minute Community Lounge there’s no way I can find the time to do some actual blogging, or even twitter these days.

    I’m not even going to try to recap yesterday in terms of announcements. No way I can keep up with the constant flow of information/announcements being published / exposed by my fellow bloggers. Most of them are featured on PlanetV12N or use twitter anyway so you can easily keep track of what’s happening at VMworld.

    I do want to tell you guys about the VMTN Experts Session we had yesterday. Although the turn up wasn’t what we hoped for I do think the session was useful. All the VMTN experts and important bloggers, and I guess we can openly call them vExperts today, were there and you actually had the chance to talk to people who’s avatar you normally only see on Twitter or the forums. The conversations we had were awesome.

    I’ve got a totally different view of some people. Some of them I only know via their short tweets or replies on the forum or even blog articles. Some posts/tweets get interpreted a certain way because of a feeling/association you have with the person. Interpreting posts on the internet is hard and I know I will definitely think different about certain people and posts, which is a good thing.

    I was really honored to meet people like Mike Laverick, Scott Herold, Jason Boche and Tom Howarth. There contributions in terms of VMTN community posts and moderation, blog articles, books and just VMware / Virtualization evangelism in general is outstanding and I highly respect their input, effort and knowledge! Great to finally meet you guys!

    Now head over to PlanetV12n and read up. I will give my take on all the announcements when the storm is over though!

    PS: A reminder to some of the bloggers out there, if you visit the Live Labs and want to take pictures / film the technology preview please ask the VMware Employees if you’re allowed to do so…

    VMTN Meet the Expert, free shirt?!!

    · ·

    Now I want to see a full packed booth tomorrow at 13:00 – the Community Booth(next to the Dell Booth). So as a incentive we will give a free t-shirt to everyone that comes and drops a question to the Experts or even starts a discussion!

    If you’re scared to asks question just head over and vote for the best of the VMworld show poll, we will also be giving away shirts for that during the day. Just come and visit the booth during the day or during the VMTN Experts Session / Meet and Greet… who doesn’t want to have a cool looking VMworld Community shirt? I know I want one so I might just ask the famous Tom Howarth a question!
