Want to be a vExpert?

Reading Time: 3 minutes

vExpert 2020 applications are open!

vexpertlogo2020

From November 25th to January 10th, you can apply to be a vExpert 2020 through many different paths and you must do it if you think you contributed to the VMware community.

What is a vExpert?

It’s an award that VMware gives to individuals who have contributed (a lot) to the VMware community.

Only the contributions over the past year are evaluated, therefore, it is a program that requires constant dedication every year by being an evangelist and advocacy of VMware products.

vExpert is not a certification! It’s an award that is given to individuals and not companies so, companies must not claim that title.

Why become one?

vExperts who participate in the program have access to exclusive benefits. One of the challenges that you will see is, the journey to be and to maintain it. As I will explain later, being active in the community (through different ways) is the key to become one!

At VMworld there are some exclusive gifts, access and parties that are only accessible to vExperts but, interacting with the community will be always your best gift in my opinion.

Here is a list of some of the benefits:

  • Join the private Slack channel (which is quite active!).
  • Permission to use the vExpert certificate and logo on your website, social media, etc.
  • Private forums on communities.vmware.com.
  • Private webinars with VMware partners as well as NFRs.
  • Evaluation licenses (1 year period) for many VMware products for your home lab!
  • Blogger early access program for vSphere and some other products.
  • Your profile will be listed in a public vExpert online directory.
  • Access to vExpert parties and exclusive gifts at both VMworld events.
  • Preferent seating at VMworld Keynotes.

How-to

Being a VMware vExpert is not a sprint and it doesn’t consist of making the greatest amount of blog-posts about VMware.

To become a VMware vExpert, you must be active in the community: This can be achieved by knowing and replying to people on Twitter, writing blog posts about VMware technologies, reply to the VMTN forums even if you don’t know the exact answer.

Assisting or presenting to VMUG events is one of the best things you can do, not just to know people, promote yourself and learn new things also because you participate in the community and let yourself know.

To apply just do it here and list all the contributions from this year (2019).

If you still have doubts, you can reach your local vExpert PRO, which will help you with your submission. I can help you if you need some guidance or need any advice, just reach me on Twitter!

Once you apply, your submission will be evaluated and once the applications are closed, the vExpert 2020 will be awarded.

Summary

By being part of the community and involving yourself more in evangelizing VMware products through posts, VMUG events/UserCons, VMTN forums, etc. you will have a high chance of being a vExpert.

 

 

Remember that in only will count the contributions from the previous year (2019 in this case) so, if you are not one know, don’t worry, apply if you think you contributed enough to the VMware community.

You didn’t contribute enough or nothing this year? Set yourself a goal and make it happen for the next year!

For me, being a vExpert gave me, not just licenses, gifts, etc. but many new friends of the community and a better knowledge of VMware products and culture.

VCAP-DCV Design exam notes

Reading Time: 4 minutes

 

As the VCAP-DCV Design 2020 certification is going to be released (but the 3V0-624 exam is not scheduled to be retired yet) on Jan 1, 2020.

Recently I made another post about my experience with this exam where I failed, check it here.

For your information, at the moment the 3V0-624 is the current exam code for the VCAP-DCV 6.5 Design certification (Also named VCAP-DCV Design 2019), always check the code for the exam no matter which is the certification name.

I decided to share with you some notes for this kind of exams no matter which version.

This information will be more helpful for people that have never taken this exam rather than those who are experienced in these advanced exams.

Audience

The Design exams (VCAP-XXX Design) are mainly for IT Architects (sounds cool?) but, why for architects? Well, if you check the blueprint, you will see a couple of sections and not many objectives. The truth is hidden inside each section, which is huge and covers many aspects.

Could you pass this exam without being an IT architect? Of course!

trust_me_architect

Many did it (not in my case yet) by studying and having a lot of design experience, or also helped doing designs with other peers for example. Also, you can gain all the knowledge of all areas and study your main gaps.

The goal is to design VMware solutions to meet specific goals and requirements, ideally, you should have advanced knowledge of storage, network, compute, end-user computing environments and other components.

You will have to develop a conceptual design given a set of customer requirements, determining which requirements needed to create a logical design and after that creating a physical design with these items.

Technical background

As you are aiming for a VMware certification, you must think in all solutions, features, and elements from vSphere.

Here is a list of the solutions that appear in the Blueprint and are related to VMware of course:

  • vSphere
  • vSAN
  • SRM
  • vROps
  • VVOLs
  • vCenter Converter

Inside each solution, you should know at least the most of the features, functionalities that they offer, dependencies between them and test them (if you can).

Apart from knowing about these technologies related to VMware, there are obviously the core areas that compose a general IT infrastructure: Storage, networking and compute.

So, be prepared to dig on each area and know about dependencies between each other and with other solutions.

Advanced knowledge is desirable (and you will be tested) on each area would deserve more than post so, I am not going to explain anything right now about it 🙂

Aiming for the exam

Your main guide must be the blueprint, no matter what other unofficial guides say (although they are very helpful). In the blueprint you will have all the sections and objectives that will be qualified.

This exam requires to read a lot (more if your daily job isn’t designing solutions) and not just books to gather information about how to gather requirements from the customer and match them to terminologies like RAMPS or RRAC (I will explain a bit of those later), also all the technical papers that the blueprint mention (+50).

Conceptual, Logical and Physical Design, you will see this a lot and once you understand it, you will see why.

You must check all the references (documents) that the blueprint mentions because most of them will appear in the exam.

Some key points from all the features, elements or products I think will be:

  • Dependencies: Know the dependencies between solutions. What do you need to enable vSAN, apart from at least 1 SSD/Flash and 1 SAS/SATA disk? It also requires vCenter and DNS.
  • Advantages and disadvantages: Does SRM perform replication? Is HA better to ensure availability than FT? Which solution can achieve a 5-minute RPO? vSAN
  • Maximums and limitations: vSphere 6.5U1 supports a maximum of 4 PSCs per site, behind an LB. Also a maximum of 10 PSCs per vSphere Domain.
  • Upgrade paths: How would you upgrade a vSphere 6.0 environment to 6.5 with external PSC?
  • Determine RCAR: Differentiate between requirements, constraints, assumptions, and risks.
  • RAMPS: Build recoverability, availability, manageability, performance, and security into a vSphere Logical Design.
  • Gather and analyze business and application requirements from customer interview data, determine customer priorities for defined objectives and categorize those requirements by infrastructure qualities.

In the post, I mentioned to you at the beginning there are some resources which are quite helpful in order to learn and improve your non-tech skills.

Summary

There is so much information to digest if you don’t have a certain level of knowledge in vSphere and the “art” of designing solutions, which could lead you to study a lot of products, methodologies, and features in probably, a great amount of time.

But don’t be impatient, it will take you time but, review each section and check the concepts, products or features that you’re not familiar with.

Check videos and other unofficial guides that probably will make other fellows from the community.

This exam is about theory so, you will be tested as an architect who designs solutions based on customer or application requirements and how to match them to a VMware design.

It is difficult to generalize all the things that can appear in past, present, and future VCAP-DCV Design certifications but I tried to give you as much information as I can.

VCAP6.5-DCV Design failed exam experience

fail-better
Reading Time: 4 minutes

Recently I took the 3V0-624 exam (a.k.a. VMware Certified Advanced Professional 6.5 – Data Center Virtualization Design Exam) and I failed (266/500).

fail-better

I took it on September, 4th (a month and a half ago) and as I was on holiday and now preparing things for VMworld Europe I won’t be able to study after the event.

I recognize, I study a bit in a rush. In just one month for someone who is daily tasks aren’t about architecture, it can be hard (or not). In my case, this rush was influenced due to leaving on vacation for more than 2 weeks. Then, I decided to give it a try before leaving but, the outcome wasn’t what someone would like!

Let me share my experience in the exam, some thoughts, resources, and notes that maybe can help you.

Know yourself

What I want to say in this section is knowing your limitations and experience against the exam. I am not going to do a comparison against the blueprint right now but, check the blueprint and be honest to yourself.

This exam is called “Design” and that means having a broad knowledge on many areas (like networking, storage, computing, hardware, etc.), a different mindset than an engineer (the famous “holistic” view that architects have).

So, basically, check all the sections in the blueprint and match them against your knowledge. Are there too many gaps? Then, you probably need more experience and a lot of time to study (or both) but definitely, the experience becomes very handy for this exam.

(I recommend you to check the blueprint from the VCAP6-DCV Design which is quite better than the 6.5 version (in fact, it has the resources split into sections instead of giving you a list of 50+ resources like in the 6.5 version).

I am not an architect but I did some projects from the scratch (small ones) and participated in others that were normal (I don’t want to say big because it is subjective) as a technical reference so, I had some of the knowledge regarding how to approach a project

Expect to gather the requirements, find “RRAC” (Requirements, Risks, Assumptions and Constraints) and also I had knowledge in DC architecture, vSphere (obviously) and other products from VMware (this is a VMware exam so don’t expect another thing!).

Study Resources

There are many resources that you can find on the internet:

Blog posts:

 

The books I read:

  • VCAP5-DCD guide
  • IT Architect: Foundation in the Art of Infrastructure Design: A Practical Guide for IT Architects
  • VMware vSphere Design 2nd Edition

Obviously I reviewed all the technical papers from the blueprint and you should too (at least check if you understand the main concept).

The exam

As the official webpage states, there are 60 questions and you have 135 minutes (2 hours and 15 minutes) to complete the exam. This is plenty of time for anyone I think.

I read other experiences and almost anyone had a lot of time left in the clock before finishing the exam. When I took it, I reviewed the questions and there were almost 30 minutes.

Questions can be large so, maybe you want to read it a couple of times or even when you’re answering it.

The format of the exam is multiple-choice, matching and drag and drop. That means that all questions won’t have a single choice solution.

Even I had time to finish the exam without looking at the clock too much, I failed with a score of 266 (passing score is 300 like many other VMware exams). That means that I need to review which were my weakest points, resolve my doubts and catch up with all I studied a couple of months ago.

Notes

As far as I know, this exam goes until ESXi 6.5 U1 (which is the latest release before the blueprint came out).

Review dependencies between all products and features within vSphere (especially the ones related to the RAMPS concept).

The conceptual, logical and physical design concepts must be mastered.

Review limitations on each feature (HA, DRS, FT, etc.) or product (vSAN, SRM, etc.).

The vBrownbag videos and books like the “VCAP5-DCD guide” can be very helpful even though are “older”. About books. the “vSphere Design 2nd edition” along with the “IT Architect series: Foundation in the art of infrastructure design” will give you a general vision of all concepts that an architect must know.

Check the blueprint from the VCAP6-DCV Design as the objectives are the same as the 6.5 version but better explained and with references on each section.

 

So, that’s all I wanted to say and I hope that even I didn’t pass in this first attempt, it can help other people willing to take it in the future.

Sometimes you have to fail better before succeed.

VMworld 2019 Europe local guide

Reading Time: 10 minutes

VMworld 2019 Europe is almost here! And I made a local guide with tips about transport, restaurants, places to go, etc. to ensure you can enjoy more your experience in VMworld.

General information

This event will take place from the 4th (Monday) to 7th (Thursday) of November at Fira Gran Via in Barcelona, Spain.

VMworld is always an amazing opportunity to learn from all the events that will happen there like the Hands-on Lab, Breakout sessions, General sessions, etc.

Also, it is a great way to connect with a lot of people from the community, vendors or other persons that you are interested in.

People are really friendly so, don’t be shy (you can try first on Twitter!) and try to speak to members from the vCommunity. Besides, be sure to meet the vBrownbag team in the VMTN Tech talks area 🙂

If you are interested in attending this amazing international event and enjoy many other advantages, you can register here.

Some notes

In Spain, tipping is entirely optional and it’s not very common so, it’s up to you if you want to leave a tip in case the service was exceptional or you think it deserves it.

In restaurants, shops, etc. the VAT tax is included. Therefore, you don’t have to worry to calculate an extra amount of money.

Also, once you pay with credit card (VISA branded cards are the most used here) they will make you enter the PIN code of your credit card (a bit different than the US).

I know it’s late but, hotels near Fira are nice and a bit expensive. The best zone I think it is near Sants where there are cheaper hotels, nice transport connections, and great ambient.

The official language in Barcelona is Spanish but most of the population speak in Catalan. Saying that, don’t worry if you don’t understand some signboards from the street or public places.

Transportation

There are 3 different train services: Renfe (Local Train), TMB (metro/subway/underground) and FGC (Regional Train).

Renfe and TMB are the most used because they have more combinations than the FGC and also better schedules. So, basically, you will see in this guide mentioning train for Renfe and metro/subway/underground for TMB.

Coming from the airport

Once you land at El Prat airport, there are a few ways to go to the city of Barcelona:

  • You can take a taxi (expensive but more convenient for people with less time or when the hotel is located in an isolated area). It will costs between 20-30 € from the Airport to Sants (always depending on the traffic). Put the hand luggage on the taxi trunk costs an additional euro.
    You can use the app myTaxi to order one.
    Uber and Cabifiy are not available in Barcelona.

You can go to the Aeroport (airport) stop of the R2 Nord line (you must go to Terminal 2 to take the train). This line will take you to Sants-Estacio and will be great for people staying near Sants.

This line is less frequent than the next option but it takes less time. Pricing is subjected to zones. In that case, From Aeroport to Sants-Estacio the price for a single ticket will be 4.20 €.

  • By metro (TMB):

Use the L9 Sud line, this is the Metro (subway/underground) service and can be combined with other lines (like L5 at Collblanc stop for example) within the same ticket.

This metro service is more frequent than the train service and it costs 4.60 €. This can be the best option for most people because you can use the same single ticket to go to other places by combining lines.

  • By bus (Aerobus):

The least recommended option as it will be crowded but it depends on your preferences and where do you want to go.

The Aerobus will take you to “Plaça Catalunya” (Catalunya Plaza) but it costs a bit more than other services (5,90 € at the moment), you can review more information in this link.

T-10 card

If you plan to visit Barcelona, consider buying a T-10 ticket (which includes 10 single tickets or 10 journeys) as it will save you half the price of many single tickets. This T-10 card can be used for many people as you want so, consider it if you are a group.

T-10 cards are sold by zones (because they have other public services integrated), as you are going to stay in Barcelona, you only need 1 zone. Price for a T-10 1 Zone card is 10.20€, versus buying 10 single tickets (1 zone) will cost 2.20 € x 10 = 22€.

T-10 tickets can be used on any public transport (bus, Metro, Renfe and FGC services) with some exceptions covered here:

  • You cannot use the T-10 ticket from the airport on the Metro Line L9 Sud. This means the T10 ticket is not valid at the stops Aeroport T1 or Aeroport T2 on the airport metro link.
  • The T10 ticket is also not valid on the Aerobus express bus.

Moving inside of Barcelona

The Metro (subway/underground) is your best choice whatever you stay in Barcelona if you want a cheaper, frequent and reliable service.

With the metro (remember the name) you can travel through lines at the same cost. The main stops to consider will be Fira in L9 Sud, Plaça Espanya in L1/L3 and Sants-Estacio in L5/L3.

The fastest way to VMworld?

The closest stop to the VMworld event is Fira in L9 Sud or the Europa-Fira stop which is another stop from the L9-Sud line that also combines with another train service (FGC trains) which is a different transport service than the metro and it has different stops.

If you stay near Sants, the Sants-Estacio stop in L5 will be your choice. Then, in Sants-Estacio station take the L5 to Collblanc stop and after that, change the line to L9 Sud until you arrive at Fira stop.

You can see in the following map the VMworld precinct highlighted in yellow and the closest stops (marked in blue): Europa-Fira stop which combines FGC and Metro services and, Fira stop at L9 Sud.

FiraGranVia-map

Last year VMworld provided a free metro card; As I don’t know if it will be the same but if you are aiming to visit Barcelona and visit other places, consider to buy a T-10 travel card (10 single rides) which is multi personal and quite cheaper than buying 10 single tickets.

 

Events around VMworld

Fred Hofer has a magnificent post where it summarizes all the events and parties that will happen on these dates, check it here

I organized the vFit runs, review my post for more detailed information

In my case besides the vFit event (Monday and Wednesday morning), I will attend the vSoccer event on Monday night and vBreakfast on Tuesday.

 

Outside VMworld (Sightseeing)

Here is a summary of the places that you could visit if you come to Barcelona:

La Sagrada Familia

Probably the most iconic building in Barcelona. It is an unfinished church designed by Gaudí, an architect who made many iconic buildings here in Barcelona.

Location: https://cutt.ly/5eoPoBU

Las Ramblas

The most famous pedestrian street of Barcelona, you will see many kiosks and artists there while walking in the middle of the city. Note: Keep an eye on your belongings if you are watching an exhibition as pickpockets could be near you.

Location: https://bit.ly/35zkqXQ

font-montjuic

La Font Màgica de Montjuïc (Magic fountain of Montjuïc)

This fountain is amazing at night. You should check the exhibitions scheduled with lights and streams creating shapes. It is located near the Veeam party that will be on Tuesday so, maybe you can go earlier and check it out!

Location: https://bit.ly/2VBo9zc

Park-guell

Park Güell

A gorgeous park with some designs from Gaudí and other architects that are interesting. You must buy a ticket in order to gain entrance to the Monumental Area (where you can see some monuments from Gaudí).

Location: https://bit.ly/319oIS3

casa-batllo

Casa Batlló

A famous building designed by Gaudí also named “House of bones”. Look at the facade which is something that you probably never seen before with the sculpted stonework, the windows or the painting. It is also a museum where you can visit (you need to buy a ticket) the inside of this building.

Location: https://cutt.ly/ieoPssI

la-pedrera

Casa Milà – La Pedrera (The stone quarry)

Another famous building designed by Gaudí. It has unique balconies and a courtyard that defines the style of Gaudí and also his last private residence.

Location: https://cutt.ly/reoPjYM

port-olimpic

The Olympic port of Barcelona (since recent events in the past months, I will avoid going at night)

It is one of the most exciting leisure and touristic spots throughout Barcelona, with a wide offering of shops, clubs, and restaurants. It’s the gateway to the Barcelona beaches and also there is the Barcelona zoo near to it.

Location: https://cutt.ly/seoPx1J

In general, avoid going alone in the night, especially in “Las Ramblas”, “El Raval” or near “Olympic Port of Barcelona”.

Also, avoid the neighborhood known as “La Mina” which is farther from Barcelona but it still accessible by Metro.

Restaurants

The food in Barcelona is nice and some of you probably know it.

Let me suggest a couple of restaurants near Fira Gran Via (VMworld):

  • Gran Varela: A restaurant with great food (especially octopus). Also, the wines are great!
  • In Gran Via 2 (a shopping center pretty close to Fira Gran via) I can suggest you:
    • A great Japanese (Udon)
    • A good Italian (La Tagliatella
    • Beers and tapas (Cañas y tapa)
  • Restaurant La Vid: A nice restaurant where you can try local food like the bread with spread tomato, the Spanish omelet, or the ham! This is also the restaurant that will be hosting the vBreakfast event on Tuesday morning.

 

The best places aren’t near Fira Gran Via but if you want to try better food, here are a couple of restaurants that are really nice:

    • Bacoa Burger: Amazing and customized burgers, also hand-made fries and sauces.
    • König: Amazing restaurant where you can try almost everything: tapas, amazing beer, flatbread, and many other options!
    • La Bella Napoli: Not many choices on the menu in this Italian restaurant but the food quality is amazing.
    • Buenos Aires Grill Restaurant: Steak, ribs, Argentinian Beef, special cuts?
    • Ramen-Ya Hiro: Best ramen in Barcelona without a doubt! The queue won’t be short to get the Ramen…

Local food

Let me put a short section about local food here. The food you must try while staying here would be: Paella, Spanish omelet, Bread with (spread) tomato and of course Ham (Jamón)!

Despite there many restaurants that they prepare all these dishes, I will avoid the ones in Las Ramblas because they’re usually not the best option…

Bread with (spread) tomato can be found in almost any bar or restaurant so, just ask for it. They are also served at breakfast!pa_amb_tomaquet

 

If you don’t want to lose a lot of time by going far from VMworld to taste many of these dishes, I would suggest you go Restaurant La Vid, which I talked in the previous section.

 

Also, on these dates, it is common for street vendors to sell hot toasted chestnuts wrapped in newspaper, give it a try!

chestnuts

Finally, you should try a sweety called “panellets” (special almond balls covered in pine nuts), you can find them in bakeries:

panellets

 

There are many other places and foods not included here. If you want something specific just let me know in the comments or via DM on Twitter.

Conclusion

That will be a summary of things to do at VMworld and in the city of Barcelona.

Be sure to enjoy VMworld with all the events, parties, people and more things that can give you but overall, have fun!

If you think that something is missing, let me know.

See you at VMworld!

 

 

 

vCSA 6.x installer error: “No networks on the host. Cannot proceed with the installation.”

Reading Time: 2 minutes

This is a quick post of an error I found sometimes while deploying a new vCenter server appliance with an embedded PSC on the vCSA 6.x installer.

The problem

In my case, I was trying to install vCSA 6.5 without DNS (this is why the system name has an IP address and the DNS is itself). Also, notice that the network section is empty:

If you try to continue with the installation, it will show you an error:

No networks on the host. Cannot proceed with the installation.

 

Solution

I checked the ESXi host and obviously, it has other port groups created in a standard virtual switch, then, which was the problem? Why I can’t see them in the drop-down list?

 

Checking on the internet I found this: https://serverfault.com/questions/886776/vcenter-server-appliance-6-5-installer-error-no-networks-on-the-host-cannot-p

So, that web page mentions the “VM network” port group that is a default port group that is created once you deploy an ESXi host. In my case, it was auto-deployed with different port groups and that one didn’t exist.

Hence, I decided to create a port group called “VM Network” in the host that I am trying to deploy the vCSA and…it worked!

Now, as you can see, I can see that port group and I was able to continue the installation with success!

It seems that with you must have this port group if you are deploying a vCSA at least from your PC, so, bear in mind if you are trying to deploy a new vCSA and you don’t have the default port groups when deploying a vCenter Server.

 

I hope this helps if someone has this issue.
