This is a post I was about to write already 2 months ago as a summary of 2020 as it’s imporant to wrap-up a long time I spent preparing for VCDX and also say Thank You. However, due to other tasks, engagements, etc. I just managed to complete it right now! So first things first – finally, after a very long and extremely informative journey at 15 Dec 2020, I finally received probably the best e-mail ever. Hi Pawel, Congratulations! You passed!…
One of the most tricky parts of vCD – networks. It took my some time to to digest how those network relations between different types of network in vCD works. Just to remind we distinguish: External Networks VDC Organization Networks vApp Networks Moreover for both VDC Orgzanization and vApp networks we distinguish folowing types: Directly connected to upper layer network Routed network Isolated Network To complicate even further vApp directly connected network can be fenced 🙂 All networks apart from…
During recent Horizon deployment with GPUs for a Customer I’ve encounter an issue related to ECC on NVIDIA P40 GPU card. By the way as per documentation it applies to all cards with Pascal architecture. In NVIDIA documentation you can find an information that apart from installing NVIDIA’s VIB you need to disable ECC. Which is clear for me. However, using nvidia-smi command after installing that VIB the status looks as follows: ECC status is listed as N/A, which I…
It took me a while to figure out what information I see while displaying VTEP, MAC and ARP table on Controller Cluster in NSX. In documentation you can find what information are included in those tables but it might not be seemingly obvious which field contains what kind of data that’s why I decided to make a short reference for myself but maybe it will help also someone else. To understand those tables I started with Central CLI to display…
There are a few caveats that make the calculation and planning of VSAN capacity tough and gets even harder when you try to map it with real consumption on the VSAN datastore level. VSAN disks objects are thin provisioned by default. Configuring full reservation of storage space through Object Space Reservation rule in Storage Policy, does not mean disk object block will be inflated on a datastore. This only means the space will be reserved and showed as used in VSAN Datastore…
Whilst using RDM disks in your environment you might notice long (even extremely long) boot time of your ESXi hosts. That’s because ESXi host uses a different technique to determine if Raw Device Mapped (RDM) LUNs are used for MSCS cluster devices, by introducing a configuration flag to mark each device as perennially reserved that is participating in an MSCS cluster. During the start of an ESXi host, the storage mid-layer attempts to discover all devices presented to an ESXi host…

In the previous part importing steps of Dukes Bank Sample Application Blueprint were described. Now it’s time to perform additional configurations steps to makes it works. (If you thought that you will be able to request sample three-tier app out of the box after you import it, you were wrong! Do not worry I overinterpreted it also when first seeing it during a training long time ago ;)) But going back to vRA Dukes Bank App – after successful import…
It is almost a tradition or habbit for me to share my experience about VMware exmination taken so far. Well, it happened, I eventually passed the VCAP6-CMA Design exam which together with previos passed VCAP6-CMA Deploy exam gave me VCIX6-CMA tiltle and badge. It looks like this:Nothing special, it was not an easy way to get it, though! The biggest problem with that IMHO is that it is and old version which is based on vRA 6.X, whilst we currently…
