Bitdefender – True Agentless protection

June 13, 2017 Kim Bottu 0

Last week I was in London at the InfoSecurity convention having a look what is happening in the security world. If you have never attended InfoSecurity, it is a free event where most of the presentations are a bit loaded on the marketing side.  Of course there are always exceptions. The 2-hour workshops are truly gems. At least the workshops which I did attend to. What if you could protect VM’s without agents or without any other piece of installed software? The workshop which really caught my attention was the workshop presented by Andrei IONESCU and Adrian Liviu ARSENE who are both employed by Bitdefender: ‘Data Center Security – HYPERVISOR INTROSPECTION’. Starting with explaining how external and internal threats are evolving they quickly moved on to explain how their […]

Very persistent NTP issues on VCSA and PSC appliances

May 11, 2017 Kim Bottu 0

For the 2 weeks I had been having very annoying NTP sync issues on some of my VCSA and PSC appliances in one of the datacenters. While my SSO domain and vCenter enhanced linked mode were for the most part working properly, it still bugged me that the NTP clocks on my PSC and VCSA in datacenter 1 were properly syncing with the NTP source (windows NTP source), but the NTP time on my PSC and VCSA in datacenter 2 were always off with somewhere between 3 to 7 minutes with the clocks of all my other appliances and Windows VM’s.  They did how ever sync properly with each other.  (For trouble shooting purposes, I pointed all appliances to a single NTP source in a single […]

A different take on the SRM upgrade order

March 3, 2017 Kim Bottu 0

Upgrading a vSphere environment with SRM can be tricky. If you follow the official best practice on how to upgrade vSphere and SRM you might find yourself in a position where SRM is out of commission because the last part of the upgrade process,  the part where you upgrade the DR site, fails. The official recommended way to upgrade SRM The official recommended way to upgrade SRM connected sites is to upgrade all components in the Primary sites first and then upgrade the components in the DR site. This means that you upgrade vCenter components followed by the SRM components in Primary Site A first, followed by vCenter components and the SRM components in Primary Site B and then by the vCenter components […]

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

January 3, 2017 Bilal Ahmed 0

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 […]

VCAP6-DCV Deployment Beta

July 18, 2016 Bilal Ahmed 0

So myself and Kim did this exam the other day. Kim hasn’t done any DCA style exam before, and he had a similar experience to me on my first go. It kind of hits you like a train and its a lot to take in initially. The beta signup period didn’t give anyone much time to actually prep for it properly. Having done the 5.5 DCA, I remember looking at  some of the questions and wondering what they were wanting……exactly. I did what I thought was correct, you don’t have time to second guess yourself, you just get on with it and do what you can. The best explanation for the DCA/Deployment exam is: Imagine you are a contractor and […]

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 […]

Testing the vSphere 6.x HTML5 webclient fling

May 16, 2016 Kim Bottu 0

I have been testing the HTML5 webclient and if you want to do the same you have to follow a few procedures. Deploy a new VM from an ova [download] which will use 2 vCPUs and 4 GB or RAM. Indeed, you need to deploy a new VM which will talk to vCenter server.  There is no vCenter deployment which comes with an embedded HTML5 client yet. The procedures on how to deploy the HTML5 webclient are well explained in the HTML5 webclient documentation and don’t take too long. The only thing you really need is a vSphere 6 deployment! Some remarks about the HTML 5 client: It is fast. There is no doubt that it is a lot faster than the current webclient. There are still […]
