A member of the Danish Arrow Blogger Board – Updated with Video

Wow, I’ve been selected as one of the top bloggers in Denmark, along with quite a lot of my own technical heroes in Denmark. Namely the Arrow ECS Blogger Board.

I’m very honored to be considered one of the bloggers that gives information back to the community,  even though my blog posts aren’t often that technical as the rest of this blogger board. All 6 of the selected people are also designated vExperts, so its a really nice selection of people.

The board consist of people like Mads Fog Albrechtlund, one of Denmark’s leading VRO/VRA specialists, who works at Proact. Michael Ryom also works at Proact as an ESXi and vRealize specialist.

There’s also the Party Duo Frank Brix and Rasmus Haslund, who works for Cohesity and Veeam, and the last member at the moment is Robert Jensen from VMware Denmark, who is the one of the new vExperts from Denmark in 2016.

So I expect that this board of bloggers will post quite a few posts about VMware and virtualization in general. Today Frank Brix and myself was interviewed by Liselotte Foverskov from Arrow about our careers and community and VMware in general.

Update: here with a link to the video in danish though

 

PernixData FVP in the Home Lab Part 3. (SUCCESS)

I must admit that I think I have made quite a few mistakes in this Install.

I was told that 6.0 is not supported by PernixData yet, but it has been known to work. So I installed a 5.5 VCSA instead, and voila it joined my AD without any problems that the 6.0 had. (Guess I need to try the 6.0 VCSA again).  Then Uninstalled and Reinstalled the PernixData Management Software, and still no plugin showed up. My friend @FrankBrix told me to look at the log files of the FVP software, and yes it would obviously there. The logfiles clearly showed that the software couldn’t connect to the SQL server, and I Discovered I had entered the wrong password!. One thing there, I do think the Installed could have checked that instead of just writing it to a config file. After correcting that, the FVP plugin worked on 5.5.

I thought that I would give 6.0 a shot again before configuring anything in FVP, and I could also get the FVP plugin to the 6.0 vCenter. However it kept giving me authentication errors, each time I tried anything with FVP. So I went back to 5.5 (now my 4.th vCenter install) and followed the guide to create an FVP cluster. After that I tried to add resources to my cluster, but it kept saying that “No PernixData compatible hosts have been detected…” So I double checked that the VIB was actually installed and I tried rebooting the ESXi, but to no avail.

Again @FrankBrix to the rescue. We setup a WebEx and in like 30 seconds after he took over my screen he had solved my problem. After reinstalling and creating datacenters and clusters 4 times, the last time I had accidently forgotten to put my host INTO the cluster. No wonder FVP couldnt get any hosts.

With that fixed PernixData started its magic. And WOW I must say, I can already feel a big difference from the last days without caching, and I’m looking forward to seeing the write Cache in action once I get all my machines up to speed again.

And damn here 1½ hours after it was created look at these stats

FVP in action

57.000 IOPS saved from my small little 4 disk Synology, no wonder I can feel a big difference.

FVP Latency

And the Latency really has gotten down as well. you can see a Big spike at around 10:22PM from the datastore, but the VM never saw it. And this is from a single cheap Kingston SSD. Will have to try this out in a heavier environment than my homelab sometime soon. I will post more stats when this has been running for some time.

Once again a big thanks to @frankbrix http://www.vfrank.org/ for the help.

 

Great VMUG Meeting in Denmark

On April 3rd VMUG Denmark held its first vMug of the year, the place was a repeat of a nice setting that was done last year as well. It was held in a Cinema and afterwards there were a showing of the new Captain America: The Winter Soldier Movie. More than 100 vMuggers had claimed a ticket for this VMUG so the cinema was filled to capacity.

It started off with Nicolai Sandager bidding us all welcome, talked about the next VMUGs in june 19th and november 20th. There will also be a VMUG in Jutland but the date hasn’t been set yet. He proceeded to give a shoutout to the 11 freshly awarded Danish vExperts, and seemingly on purpose omitting Frank Brix on the list on the screen :).

The first presentation, was done by one of the sponsors of the event Bitdefender, who talked about their antivirus products. To be honest that was the low point of the day. Not that many people really care about antivirus, its one of those things you have to do, and causes problems once in a while, but no more than that. I’m thinking its kinda hard to make such a topic interesting for a room full of VMware geeks.

The next presentation was something entirely different. Mads Fog, one of a new vExperts, did a very interesting presentation on his ventures into getting vSphere to run on Apple hardware. Seems like a real niche thing, but i’m guessing it has some use cases around the world. You can read more about Mads’ work here

After a break PernixData founder and CEO Poojan Kumar took the stage with Frank Brix as his Wingman doing a product demo. Poojan took us through the basics of how PernixData was created “2 guys and a Powerpoint”. And gave us a really nice presentation on PernixData FVP. The product actually seems very nice, but I havent seen many Danish companies adopting it yet. But it shows great promise, and I do believe that i could find more than one use case for FVP at my job.

Next up was Scott Lowe who gave a very good introduction to Cloud Networking. And even though the presentation simply was called “NSX – Scott Lowe” most of the time was spent on talking about what you would require of a technology that was deemed Cloud Networking. For those of us who aren’t working with networking on a daily basis this was a really great introduction. And of course it’s always a great help that Scott is a such a good presenter.

After his presentation Scott had a meeting with the Danish VCDX Study group, while the rest of us networked.

The last presentation of the day was done by Lego Geek Simon Gallagher about his vTardis platform, and its evolution from a noisy and heat producing Compaq server to his latest version that ran on his way more wife friendly 32Gb Laptop. vTardis is his lab setup for vSphere, running nested ESXi’s inside VMware Workstation. This actually seems like a very good way to do test labs. 2 of the key take-aways from this was, Autodeploy is your friend, and DO invest in an SSD disc for your lab, otherwise you’ll end up waiting for hours for stuff to boot.

That concluded the days presentation and after a run to grab Coke and Popcorn it was time for Captain America: The Winter Soldier. In my opinion very american movie with a lot of action, which let you switch off your brain and just watch 🙂

The day ended with a vBeers event, in which more than 30 vMuggers partook, a great conclusion on another great VMUG by the Danish VMUG-team. Looking forward to the next VMUG
