NPP 5.0 Study Tips

NPP 5.0 Study Tips

So after the below happening this week I thought it would be best if I get a study guide/tips up to try and help others. I also have to put out a massive thanks to James Brown who helped with my studies and put me on the right track


The first biggest tip I can give is forget anything 5.5! I went in the first time and after reflection speaking with James I put down way to many answers as 5.5 and not 5.0. Remember this is a 5.0 exam at the time of writing and not 5.5.

The next bit of advise I can give is play with the system and do a few things outside of the norm or what you may only do once but a few times as this will help. The other bit is read plenty of Nutanix blogs as this goes into some of the detail you may need. A few to note are below that I used

Nutanix Bible

Nutanixpedia and their study guide

Also Josh Odgers blog has a wealth of information that’s great to study over

Finally the Nutanix corporate blog posts are great one example I used studying was here and the support portal on your account oh and don’t forget Nu.School

A few of my thoughts on the exam and courseware though for a second is I think it’s great especially for people like me trying to move from technical to architecture. The depth of which it covers the hypervisor such as Zeus and Medusa so you have a true understanding on how things talk and what they are protecting when you are building your system is outstanding.

It also provides some real work example you may not touch day to day such as migration from VMware to AHV

If this isn’t enough I can only say get more day to day exposure and why not by using the CE version in your lab or even in the cloud, failing that reach out to the community! I am glad I did and you will find people are more than happy to mentor

So what does that mean next for me… Well its a blog post in its own right but after a chat with James and am certainly thinking of trying to set a goal of passing my NPX. Once I get on this journey I know this will spawn a whole series of posts not just one but that’s for another day so watch out!

Some news for 2018 and a new job

Some news for 2018 and a new job

A few of you may already know some of the below but I wanted to put a few notes up about the start of the year and some of my achievements after my goal post mainly so I can look back on this

First things first I have moved to a new role and one week down I am already loving it. It was an incredibly hard decision to make and I have even gone for a sector I haven’t had that much experience in but tech is tech and the way the cloud is accelerating things I thought there was no harm.

I have left what others would describe as a very comfortable (yet busy) life at Commercial and started to work for one of the UKs biggest green energy suppliers Ecotricity. Commercial were a great company but Ecotricity have some amazing projects lined up some of which I have some experience in and some where I really feel I can push myself onto the next level. I am also hoping that this can elevate and expose me to more architecture decisions so that I can learn from them and of course gain experience so I can take that movement from engineer to architect.

I have also recently had my first NTC (Nutanix Technology Champion) call after being selected as a candidate late 2017. After the role change I have found some more time for the lab again and I now have my first 3 node Nutanix cluster running alongside the rest of my stuff. I will be writing an NTC post very shortly.

I have already eluded to it before but I also want to see what else I can get done with the VR stuff and see what else I can integrate with it. I really want to get better with APIs as have recently seen a few Meraki ones based on the below video and something like turning off the kids WiFi would be great

 

 

I am also super excited that VMware on AWS is coming to Europe soon so hoping I can get on a workshop on it this year and this along with AWS and Azure of course. I then want to see if I can tie all these and Nutanix together somehow and lets not forget about Oracle & Ravello.

I know myself and the team and also hoping to make a some more podcasts for OpenTechCast and I know I have a few things to do for the lab including a Xeon upgrade once I can find a suitable motherboard. If you have any ideas for the podcast do reach out!

 

 

 

 

VMware VRDCEX Live & Tech UG Meetings

Of late I have been a little behind with blogging due to a few bush fires sidelining me during projects and the recent weather in the UK but I really wanted to get this post out along with a few others over the next few days.

I was lucky enough to be invited to not only one but two TechUG meetings and drove some discussions there. I tried to keep this as interactive as possible and after the first live demo success I re ran my home lab slides. If you wanted my slides from that day they are here don’t forget your books!

TechUGNov2017Slides

But the most interesting bit was I decided to live demo of VRDCEX and each time it went fairly well. This is an absolutely awesome project and can’t wait to see it grow. I certainly don’t match up to Alan or Pat’s delivery but I think I will get better with practise.

They are both in 4K so if anything I will use these as testers on things

The next big thing for me is now that I have this going on the Oculus I want to see if I can I get this going on my HP Mixed Reality Headset and then where can I further expand on this. Can I get APIs on here for switches and firewalls etc and then produce smoke coming out of them if they are broken! Again with mixed reality can I look at the server and then expand it out!!!

If you haven’t do so already go grab the files or my post here on how to make this work with the Oculus if you don’t have a HTC Vive

Sunday of VMWorld US 2017 & General Session

Sunday of VMWorld US 2017 & General Session

Firstly I have to put out a major thanks to Rubrik for making this possible by selecting me as their competition winner. They are a great bunch of people and it was amazing to meet them in person at long last.

I also managed to meet loads of other people who I aspire to. It was just a shame I was too tired to get any photos but Angelo did manage to grab a snap

 


I know I will be covering this in a podcast I am doing on conference differences but America does it way bigger than us in Europe.

Firstly I want to cover a few key tips on VMworld survival

 

  1. Hydrate – This is key to beating jet lag and also so you don’t feel rough by the end of the day
  2. Don’t over pack – Just don’t! You will get tons of t-shirts, socks and other random things you will need to get home. Also check with your airline as you may be able to carry on an extra bag like British Airways. I can have a hand luggage bag and a laptop bag
  3. Plan Plan and then unplan – It is key to book sessions that are a must for you like I am doing NSX and VMware on AWS but book other interesting sessions and make as many as you can.
  4. Take a break – Go hunt out the hands on labs and go relax for a bit to let things settle in. It’s also a great place to learn and get on CloudCredibility also meeting NoellGrier @CloudCredGeek If I get time I may even relax by the pool for an hour with Melissa (@VMiss33) new book
  5. Community – This leads me in nicely to the community stuff. Do you see the VMTN guys and also get involved in the collaborative events such as the Hackathon. I will be writing a post about this once I have done it tonight. Community is key and make our whole ecosystem so vibrant and there are some many interesting people to meet and learn from.
  6. Network – Go meet new people, people you know of online or go find a friend from local VMUGs
  7. Power – Make sure you have adaptors and power packs…. You will need them! If you don’t have one there is always someone giving them away and go try and get one.
  8. Accommodation – Book this early and plan out any parties that you can. Luckily most mine appears to be near my hotel or a short walk between the hotels so that will save on transport
  9. Enjoy yourself – Also remember to enjoy yourself as you are around like minded individuals and you are all trying to achieve your goals

 

The hall holding the general session was also very large and I hope they take some of the cool bits from here and do them in Barcelona. The live art work was pretty cool

The keynote was pretty exciting for me and many great things have become generally available

  • VMware on AWS
  • VMware App Defence
  • Cyber Hygiene
  • NSX being the “secret sauce”

 

Here are a few of my tweets and resources for this

 

 

Here is a link thanks to Anthony Hook about the Cyber Hygiene White Paper https://t.co/NI9zU4Mi93 This excites me from my security perspective in the fact the industry is taking this more seriously

 

I have just finished my 1st few session of the day on AWS and again this is a really interesting technology. Not having to worry about rack and stacking or even running things at 80% + as well because host failures will only take a few hours till they are fixed and are no longer your issue.

This takes me back to my things of America does this way bigger than Europe.  As you can see below the rooms are much bigger than the one in Barcelona and also the lunch hall is massive

Also please do check out some of the official bloggers  such as Chris Bradshaw who I know from the London VMUG https://twitter.com/aldershotchris/status/902226011277975553

 

Ravello 2017 Bloggers Conference – Opening Post #RBD1

Ravello 2017 Bloggers Conference – Opening Post #RBD1

Firstly I just wanted to open this up and thank John, Kat, Amy, Oracle and Ravello for selecting me as a delegate for this event. I thoroughly enjoyed it and I certainly hope we can stay engaged and make it to the next one. I certainly hope this is many more events to come.

The main point I want to make even if you don’t read all this and subsequent posts is that wow Oracle is back in the game. I know like many I did not know what to expect out of the day but I am glad about the way Oracle/Ravello handled the day and it’s certainly put Oracle back on my roadmap. I feel they are really bringing something to the cloud table and yes this is not a one size fits all but I can see why they have chosen to do things the way they have. For me being able to have the Oracle support and the cost/flexibility of running up a baremetal machine like a cloud server is great!

I also love they fact as they put it this was a good, bad and/or ugly warts and all session of which they wanted our feedback. It was great to see a vendor willing to engage with the community and even offer us a chance to say no that’s not a good idea and take it on board as you could clearly see they wanted to be transparent to allow the product to grow in the right direction.

The most powerful message for me of the day to take away was that what you have to change is nothing

Screen Shot 2017-05-24 at 11.04.59.png

We all arrived at Oracle’s conference center just after 08:00 and by this time my body was slowly starting to catch up

The day was kicked off by a good breakfast and we were provided time to network around our table and get to know one another.

John provided a great opening speech as always

At this point he handed the baton over to Navin Thadani and he at long last let us know why the industry felt they had gone quiet. Their first objective was to tackle integration the 2nd was product development. I felt this helped put all our minds at rest and set the tone for the day.

Clay Magouyrk was then up and started to cover off Oracle’s cloud vision and how they are looking to execute this. He covered off their background and how Software as a service is not new to them, they have been at this for 10+ years. The main driver for all this was customer integrations and customers wanting to modify the software. Eventually, restrictions started to stop the users flexibility so things needed to change.

Because of this Oracle took a step back and started up Clay’s team as they wanted to go into this for the long game. This is where the 2nd generation cloud came in and they started to work on the limitations of each of the already existing systems in their portfolio. Everything was started from the ground up even down to people, systems, infrastructure and networking.

What this drove Oracle to do is to try and retain the best bits such as self-service, pay for what you use with it being elastic but they need to balance this with the enterprise requirements such as security, pricing, performance and SLAs

Here come the acronyms now though…. There is now High Available zones and Domains. Their spin on zones is a DC within a region of which I feel is a much easier way of understanding this.

OracleNGCloud_Page_03.jpgOracleNGCloud_Page_04.jpg

The network in their instance is that it’s not oversubscribed along with off box networking virtualisation to allow the customer to manage theses aspects. The nice thing here they noted is none of this management is running on the compute nodes thus it will not affect any performance.

OracleNGCloud_Page_05.jpgOracleNGCloud_Page_06.jpg

The key thing this allows is that them to run is baremetals systems so it’s possible to have full root access to the compute node (apart from ILOM) to integrate into the rest of your stack. It then also allows intergrations with other devices such as F5s and other nodes that can be plugged in but still managed.

OracleNGCloud_Page_08

They also support direct connections with cross connects and VPN to gain access to these networks along with load balancing.

OracleNGCloud_Page_10.jpgOracleNGCloud_Page_11.jpg

I dont have pricing to hand but I know transit is by far one of the most expensive components of the Cloud of which ties you know. This is one thing they want to change so that you have choice. They have shown us some very attractive offerings and once these are published I will share them as they are a breath of fresh air in our industry.

To ensure all this all works there are redundant links between that data centres of which work in opposite paths. This does mean the minimum buy-in is always two ie 2 VPN or MPLS connections into each availability domain. The key thing is this needs to scale and no matter what a DC can always lose connectivity.

The Dyn DNS was a shock to me. I didn’t know they had bought them but this will also start to integrate throughout the year to even allow this withinside the network. This could help with DC failovers and public IPs

OracleNGCloud_Page_12.jpg

I did certainly like Eric’s marketing advice for this slide

 

As expected this offering is the best in breed for Oracle databases in the cloud

The next slide showed us why we were all there, the Ravello integration.  My only issue with this slide and it says great for X but again it can also be great for Production usage with the right architecture. I feel they really missed this punch line but didnt expand and offer this message throughour the rest of the day.

OracleNGCloud_Page_15.jpg

To follow up from this we started to cover the cloud table stakes. I think this summarizes many organisations plus and pain points really well.

OracleNGCloud_Page_17.jpg

Next Clay highlighted the main points, Uncompromised security such as covering physical isolation, high-security network, segregated zones and audits along with governance and control ensuring separate production/test/dev and separate IT and Dev responsibilities.

The next part was quite exciting for me which is the bare metal solution. In essence, they don’t care what you run on here it could be VMware, Microsoft, Citrix etc but for me, this is a great idea. At the moment it’s great putting apps in the cloud but this way you could host VDIs close to the app to prevent data ingress charges or even old CRM or Backoffice packages to reduce your latency but it takes away they headache of managing a data centre and the other bits that go with it.

OracleNGCloud_Page_20.jpg

At this stage I did ask about  a London DC ws on their roadmap somewhat selfishly but I have been advised they hope this is coming very late in 2017 to expand on from Frankfurt.

The slides then went off with some NDA stuff of which when I can share I will but it all very excting things.

At this point I am going to stop this post as I feel the other topics deserve posts of their own with what is coming up, a deep dive on HVX and the Ravello roadmap as it currently stands. But overall the day was great and I cannot wait for the next one and what they team will share with us over the coming weeks so watch this space.

VCSA 6.5 Installation Errors

VCSA 6.5 Installation Errors

If like a few of you I rushed off to install the latest VCSA, you may have come across some errors. I attempted multiple installs prior to consulting with Google and then came across this article by Olivier Gosselin.

With my limited French I was able to get enough out of this to spark an idea. The first thing I did was of course try was using an IP as the host name but it still failed. I can only assume this was still down to DNS and the NTP server.

Most of you would think this is not an issue but for me it was as I was starting from nothing. I also thought this was a good time to start my domain again too.

I fired up a new Windows 2016 DC on local disks attached to another server, then I got the bare basics up on including an A record for the VCSA. From here I tried the install again. I pointed the DNS and NTP to this server also using the default SSO settings and it worked!

This has made me want to try and install one more time later this week to see if this is a bug or not. The main thing that puzzles me is what does this mean for completely clean installs for a new site or even customer…. is there still an assumption here you have the DC, DNS and NTP all configured elsewhere. I know some sites I have gone to the DC is set up on the new environment and how can you do this if lets say you have a nice new 3 node VSAN… don’t you need the VCSA to create this in the first place?
