VCDX Defense Presentation: Mapping it’s genome

May 10, 2017 Jason Grierson 1

So after hours of working on your design, submission, and with some patient waiting you finally get that email from VMware stating your design has been accepted for defense!  Quickly you go into over drive and start ferociously working on your defense presentation.  Now maybe you already started working on your design presentation, maybe you haven’t but I find the questions typically always have a trend of similarity with the biggest one being: HOW do I take a 100-500 page VMware design and cram it into 20-30 presentation slides and get the message across in 75min? So first off why 20-30 slides?  Well taking the 75min you have to defend and dividing that by 20 will leave you roughly 3.75min […]

WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9 Updated: 03/01/2017

So this has been an ongoing saga for quite a while: Repeated VDDK error 1 and 2 This is an issue I blogged about a little while ago too, right here: WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9 It has been causing people plenty of issues and although it’s simple to fix, it’s annoying and it shouldn’t be happening! Veeam and VMware have been pointing the finger at each other for months now. Personally I would lean to it being a VMware issue, simply because a restart of the management agents resolves the issue. So I have been following the thread on the Veeam forums and there has finally been an update! VMware have […]

The Host Virtual MAC Address Riddle

September 5, 2016 Bilal Ahmed 1

For ages I have been pondering over ‘something’ which seems very trivial and the fact I can’t get any solid info on it is driving me nuts: Why does every pNIC also have a virtual MAC address? So here with have the VMkernel ports, a VSS and pNICS: Just as you would expect, every physical NIC (pNIC) on a host has a MAC address. BUT when you type ‘esxcfg-info -n‘ in the shell, you will notice that every vmnic also has a Virtual MAC Address!   \==+Physical Nic : |—-Name…………………………………………..vmnic3 |—-PCI Segment…………………………………….0 |—-PCI Bus………………………………………..2 |—-PCI Slot……………………………………….0 |—-PCI function……………………………………1 |—-MAC Address…………………………………….XX:XX:XX:32:06:1f |—-Virtual MAC Address……………………………..00:50:56:52:06:1f |—-FPT Shareable………………………………..true Now as you can see the Virtual MAC Address starts off with a VMware MAC and then finishes at the […]

Bootstrap a Single-node VSAN Cluster under Running vCenter Server

July 23, 2016 Shady ElMalatawey 0

In my NSX Lab, I needed a single-node cluster with VSAN enabled beside another normal cluster with three nodes. William Lam has a genius post about how to bootstrap a single-node VSAN cluster to add your vCenter on it in your lab, but unfortunately even though his advice works perfectly when you have a single ESXi host, it does not work well when you already have a vCenter in place. My story begins from the VSAN Default Storage Policy. This policy enforces that a deployment of VMs needs to have: Failures to Tolerate set to 1 (FTT =1 ): That means that the minimum number of nodes has to be 3 nodes and each VM disk has to be configured in RAID-1. Number of disk stripes=1: […]

VCAP-DCD6 Just Went GA

July 22, 2016 Jason Grierson 0

Hey All So many of you have been waiting for the new VCAP6 line to launch it seems some of the exams went GA yesterday.  The newly renamed DCD6 – VCAP6-DCV Design has gone GA and information around it can be found here: https://mylearn.vmware.com/mgrReg/plan.cfm?plan=88743&ui=www_cert However it seems they are still working out some registration issues as when I tried to register it wasn’t showing up on Pearson Vue’s site.  So hopefully this will get squared away shortly.  Once I have a chance to sit the exam I will hard at work on developing new material for the DCD simulator 2.0 along with some new documentation to go along with it.  I look forward to getting this new material out there […]

WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9

June 7, 2016 Bilal Ahmed 4

Also read the follow up post: VeeAM Backup VDDK error Follow-up and solution So recently I came across a strange problem. Random VMs from various different jobs, would fail to back up, I would get a VDDK error. Now the last time I had this error, was when I had just joined a company and it turned out to be a faulty disk on a local host that had failed,  and it had been in a failed state for so long that the whole vdisk on the Dell host was compromised and I had a punctured RAID. There was no monitoring in place! rest assured that’s sorted now. But these were all SAN based, on different datastores and on different SANs. […]

VMAX3 with Solutions Enabler and vSphere SRM 6.0 Configuration Guide

June 5, 2016 Shady ElMalatawey 0

Last weekend, I was engaged by one of our biggest clients, a bank, to upgrade its virtual infrastructure to vSphere 6 and to migrate their infrastructure to new VMAX 3 storage arrays in both main and DR site. It’s one of only two customers in Egypt that uses vSphere SRM with VMAX Arrays for DR purposes. VMAX3 Arrays are enterprise-level arrays from EMC. They’re the descendant of the great Symmetrix Arrays and they use their own replication engine, Symmetrix Remote Data Facility (SRDF). To manage SRDF and integrate it with any other solution for DR Automation and Management, it requires a software component called Solutions Enabler (SE). This software consists of a client and a server component. SE server is either installed on a […]

The death of an icon – literally

May 18, 2016 Don Ward 2

As I type this we are about to go to a special WebEx meeting for vExperts only but by the time you read this; VMware would have announced this on their blog and the gag can come off! So after enduring a huge amount of pain due to typical conference call pings/rings/background noise we eventually got down to business. The meeting is basically telling us we are going to get a new GUI to manage VMware estates however there can be only one (cue Highlander movie MEME). What does this mean? Well it means: VMware are no longer offering C sharp client (VI CLIENT) in the next release of vSphere So what is the low down and why did VMware […]
