This seems to be my last blog post for 2019 and it covers covers objective 2.4 (Build manageability requirements into a vSphere 6.x logical design) of the VCAP6.5-DCV Design exam. It is based on the VMware Certified Advanced Professional 6.5 in Data Center Virtualization Design (3V0-624) Exam Preparation Guide (last update August 2017). The necessary skills and abilities are documented in the exam prep guide for the older VCAP6-DCV Design exam (3V0-622).

This blog post covers objective 2.3 (Build availability requirements into a vSphere 6.x logical design) of the VCAP6.5-DCV Design exam. It is based on the VMware Certified Advanced Professional 6.5 in Data Center Virtualization Design (3V0-624) Exam Preparation Guide (last update August 2017). The necessary skills and abilities are documented in the exam prep guide for the older VCAP6-DCV Design exam (3V0-622). I think they also apply to the current version of the exam:

Not every customer is running a full-blown vSphere Enterprise Plus licensing. To be honest, when I look at the number of sold licenses, most of my customers are running vSphere Essentials Plus. Not Essentials, nor Standard or Enterprise (Plus), but two or three hosts with Essentials Plus. And that’s perfectly fine! Two or three hosts with 10 GbE and pretty often 12G SAS. Some of them with Fibre-Channel, nearly no one with iSCSI.

If you found this blog post because you are searchting for a solution for a FAN FAILURE on your ProLiant Gen10 HW after applying the latest ESXi 6.7 patches, then use this shortcut for the workaround: Fan health sensors report false alarms on HPE Gen10 Servers with ESXi 6.7 I had a really annoying problem at one of my customers. After deploying new VMware ESXi hosts (HPE ProLiant DL380 Gen10) along with an upgrade of the vCenter Server Appliance to 6.

This blog post covers objective 2.2 (Map service dependencies) of the VCAP6.5-DCV Design exam. It is based on the VMware Certified Advanced Professional 6.5 in Data Center Virtualization Design (3V0-624) Exam Preparation Guide (last update August 2017). The necessary skills and abilities are documented in the exam prep guide for the older VCAP6-DCV Design exam (3V0-622). I think they also apply to the current version of the exam: Evaluate dependencies for infrastructure and application services that will be included in a vSphere design Create Entity Relationship Diagrams that map service relationships and dependencies Analyze interfaces to be used with new and existing business processes Determine service dependencies for logical components Include service dependencies in a vSphere 6.

Last week I had to setup a small Active Directory Federation Services (ADFS) farm that will be used to allow Single Sign-On (SSO) with Office 365. Active Directory Federation Services (ADFS) is a solution developed by Microsoft to provide users an authenticated access to applications, that are not capable of using Integrated Windows Authentication (IWA). Required by the customer was a two node ADFS farm located on the internal network, and a two node ADFS Proxy farm located at the DMZ.

Actually, yesterday should be the day at which I migrate one of the last physical Windows vCenter servers installed in my customer base. Actually… the migration failed twice. And each time I had to rollback, power-on the old physical server, reset the computer account etc. The update was from VMware vCenter Server 6.0 Update 3d (7462484) on a Windows 2012 R2 server to vCenter Server 6.7 Update 3 (Appliance). The migration failed at 62% with the following message:

The last few weeks have been quite busy. Time to focus on exam preparation again. Let’s start with the first objective of the second section. This blog post covers objective 2.1 (Map business requirements to a vSphere 6.x logical design) of the VCAP6.5-DCV Design exam. It is based on the VMware Certified Advanced Professional 6.5 in Data Center Virtualization Design (3V0-624) Exam Preparation Guide (last update August 2017). The necessary skills and abilities are documented in the exam prep guide for the older VCAP6-DCV Design exam (3V0-622).

This issue is described in KB2971270 and is fixed in Exchange 2013 CU6. I published this blog post in July 2015 and it is still relevant. The feedback for this blog post was incredible, and I’m not joking when I say: I saved many admins weekends. ;) It has shown, that this error still occurs with Exchange 2016 and even 2019. Maybe not because of the same, with Exchange 2013 CU6 fixed bug, but maybe for other reasons.

It is time for some words of wisdom, in regard to Exchange and the supported Active Directory environments. It is the same as with the supported. NET Framework releases: Latest release does not automatically mean “supported”. To be honest: I nearly nuked a customer environment with ~ 300 users yesterday by preparing the domain for the first Windows Server 2019 Domain Controller.
