VMworld Europe 2014 – Day Three Roundup and Closing Thoughts

Well that’s it, its all over! Having never been to a VMworld prior to this week, I have to say the event does indeed live up to the hype!

Day Three
Day three started pretty subdued, not only from the point of view of the attendees, but a couple of the presenters as well; it definitely seems people had a good time at the VMworld party the night before!

Mixing in a bit of session time with a visit to the solution exchange and a bit of Hands on Labbing was the order of the day. I did have a quite amusing chat with one of the guys working on the Oracle stand. He said that the vast majority of people who had spoken to him had berated them about licensing and support in virtual environments, along with asking why they were advertising OVM at a VMware event. I think the poor guy was not far from the end of his tether!

My last role was at Oracle, so I can fully feel the pain around the license questions as it was almost always the first thing people asked me about when I told them I worked there! It doesn’t help the fact that the latest licensing hard vs soft partitioning guide is still only from 2011!

Oracle Tastiness!

Oracle Tastiness!

One thing I will be very interested to see is what becomes the defacto stance on how many hosts you must license once share-nothing VMotion between clusters, vCenters and DCs comes along in vSphere 6. It begs the question whether any Oracle auditor might have the audacity to suggest that you need to license all hosts in all DCs?

This of course assumes that the specific auditor will not accept mandatory cluster affinity as per Richard’s comments here: http://www.licenseconsulting.eu/vmworld-tv-oracle-on-licensing-vmware-virtualized-environments-updated/

Hopefully in this scenario, common sense would prevail, but that’s deep enough down that rabbit hole for now! 🙂

The sessions I managed to attend on day 3 were as follows:

STO2521 – VSAN Best Practices
Rawlinson Rivera & Kiran Madnani provided a very useful overview of a number of example use cases and how to apply different VSAN configurations. As this was covering multiple use cases there was some repetition of content, but not so far as to be distracting. Key takeaway, when it comes to disk groups, more = better!

STO2496 – Storage Best Practices for Next-Gen Storage Platforms
Being a bit of a storage geek, for me this was one of the best sessions of the entire week. Not only entertaining, but the quantity and quality of the information was intense to say the least! A couple of key areas which they covered were around benchmarking of storage (not just using the standard 4k 100% Read profiles which vendors use to produce stats for their marketing material).

TEX1985 – Lessons Learned from a Real Life VSAN POC at Trend Micro
It’s always interesting to see how real customers found the use of a technology. Arsenio Mateos from Trend Micro was not particularly detailed in any specific issues they experienced, as he concentrated more on the decisions behind the solution, and the benefits it broupght them.  Cormac on the other hand was very open and when into some detail as to some of the configuration issues and bugs which were common among other customer deployments. I was also the grateful recipient of a signed copy of the book Cormac co-wrote with Duncan Epping.

EUC2027 – Characterise Performance in Horizon 6
My final session rounded out the end of the day. I don’t currently use or design VMware Horizon View in my current role, when most commonly customers have managed RDS or Citrix XenApp farms. I mainly went to the session to see the VMware approach to sizing the new session host desktops on Horizon 6. Unsurprisingly it turns out that they come out with very similar ratios and guidelines as Citrix do (shocking)!  The really interesting takeaway for me from this session was the VMware View Planner tool, which looked like it could definitely have some value in load testing and gauging the requirements for customers with or without VMware View.

By this time it was 4.30, and everything had closed. If I’m honest I was a bit gutted as I had believed the HoLs were going to be open until 6. I was most of the way through my NSX lab, so I guess I’ll just have to finish it up from home!

After the event, my remaining colleagues and I wandered into town to check out the Sagrada Familia, and grab some light refreshments + tasty tapas.

Wrapping Up
Session Surveys – The one thing I didn’t actually get done at the show (but I plan to fill in this weekend), was the session surveys. I understand these are as valuable to the speakers as to VMware, so I have no issues spending a bit of time giving feedback. If you haven’t already, then I suggest you do, especially if you want to see the same guys & gals back next year!

If I were to be able to make any suggestions to VMware for next year they would be few and far between:

  • Keep the hang space and hands on labs and/or solution exchange open until 6pm on day 3. It’s minimal extra effort but it will allow attendees to make the absolute most of the event and facilities, especially those who don’t have an early flight back the same day.
  • Make the information on getting to the event a bit easier to find on the VMworld.com site (rather than burying it in the FAQs)
  • Free Segways or (or foot massages) for all attendees!

I enjoyed a wander or two around the solution hall, but for me the best and most useful elements of the entire week were the breakout sessions (and being there live giving me the opportunity to ask questions at the end), and networking with others both in the event and at the vendor sponsored evenings.

As a side note, I will probably be creating PDFs of all of my notes and posting these on the blog imminently for anyone who may find them useful.

So finally a big thank you to everyone who made VMworld a success; the organisers, the vendors, the speakers, the HoL team and all of the people with whom I had the such interesting and entertaining discussions!

VMware VCP5 Exam Prep Guide

So its that time of year again, when we VCPs have to bone up on the latest developments in the VCP world and get our exam done in time before we have to go cap in hand to our line management asking for them to pay for a course we never needed in the first place. In order to avoid this embarrassment, VMware kindly give us the opportunity (as existing VCPs) to pass the VCP-510 exam by 29th Feb 2012, bypassing the course attendance requirement (fair enough!).

As per usual, I have left this pretty much until as late as I feasibly can while still giving time for the (hopefully never required as yet) resit, meaning I am booked in to sit my exam on 1st Feb.

For the sake of others who are also planning to take this exam, I plan to post the links to all of my study aids below, along with any other hints/tips I come across for studying towards the VCP5 exam. If it only helps out one or two people it’ll be worth the effort.

One point worth highlighting is that reading books is all very well and good, but there’s no substitute for actually “doing it”. The best thing I would suggest is to create a home lab and use the vSphere 60 day evaluation to have a play with all the latest features. I have accomplished this in a couple of ways, but I found the most flexible to be running 2 x ESXi hosts and a copy of FreeNAS 7 inside VMware Workstation 8 (using NFS or iSCSI). I’ll try to create a post on this when I have time, but do a quick search on google for lots of other people with similar setups.

This should be considered a “living list” for now, and I will endeavour to update it as I find/use further resources.

  • Mastering VMware vSphere 5 by Scott Lowe (Kindle Edition)
    A superb resource. Even though I am already VCP3 and 4 certified, it is still worth a full read, in part as a refresher, and in part because it does highlight many of the updates with vSphere. Kindle edition is also cheaper, and lets be honest, as vSphere 5 will be out of date in another couple of years, do you really need 2 kgs of dead tree choking up your bookshelf, when you could just have an electronic copy, which you can share across all your devices?
    I have spent an hour or two a night reading and taking notes from this for a couple of weeks, which is a lot less painful than trying to get through it in one go, and hopefully should ensure slightly better retention!
  • VMware vSphere 5 Clustering Technical Deepdive by Duncan Epping and Frank Denneman (Kindle Edition)
    Having read the vSphere 4 version of this (first Kindle book I ever bought) in prep for my VCAP-DCD 4 (still to sit), I can confirm Duncan and Frank are very capable teachers! An excellent resource which goes above and beyond the VCP requirements, but will give you a much more in depth understanding of HA, DRS, DPM, SDRS, etc. This will be invaluable when the VCAP exams are out for vSphere 5!
  • VCP 5 Exam Blueprint
    If you know all this, then you cant fail!
  • What’s New in vSphere 5.0 Overview
    A quick reminder / highlight list of all the new features in vSphere 5
  • What’s New in vSphere 5.0 – Technical Whitepapers
    Licensing, Pricing and Packaging
    Particularly useful for a quick reminder skim for all the new features, prior to the exam.
  • vSphere Private Cloud Service Definition
    Whitepaper covering key terms.
  • vSphere Storage Appliance
    Official VMware blog post with documentation links for VSA stuff. Not covered in Scott Lowe’s Mastering Vsphere 5, but you will almost certainly be asked some questions on VSA in the exam.
  • Official VMware Mock VCP510 Exam
    An excellent resource, especially if you have never taken a VCP exam before. HINT: If you can pass this, you’re probably good to go for the real exam.
  • VCP5 Practice Questions by Paul McSharry
    A great set of practice questions being regularly updated with extra questions… I actually met Paul when he taught my VMware vSphere Design [4.x] workshop. A very knowledgeable guy, and his website (www.elasticsky.co.uk) is well worth checking out and subscribing.
  • VCP Practice Exams by Simon Long
    A boat-load of questions here coving general knowledge and config maximums per feature.

Please feel free to send me any links to practice questions and I’ll vet them and add them to the above list.

UPDATE: Passed the exam. See here for my exam review:
