I’ve now setup a new blog site in readiness for VMworld 2017 Barcelona and hopefully get back into the swing of posting content on a regular basis.

Now at http://www.bryanoconnor21.co.uk

I’ve just sat and passed my VCP-NV and with that I now hold all VCPs, VCP-Cloud/DCV/DT and NV and that also means no worrying about decertification for another 2 years.

Managing User Accounts in Windows 2012 Active Directory March 30, 2013

One of the courses I teach is the Microsoft Windows 2012 Installing and Configuring course, the Microsoft designation is the 20410B

In the presentation, I cover an overview Managing User Accounts in Windows Server 2012 DNS

This demonstration shows you how to do basic User Account Management. To do this we use Active Directory Users and Computers. However AD management is quite a complex topic and later demos will cover more of the AD Utilities available. Below is a brief description of each

Active Directory Administration Snap-Ins


Most AD DS administration is performed with the following snap-ins and consoles:


  • Active Directory Users and Computers. This snap-in manages most common day-to-day resources, including users, groups, computers, and organizational units (OUs). This is likely to be the most heavily used snap-in for an Active Directory administrator.


  • Active Directory Sites and Services. This snap-in manages replication, network topology, and related services.


  • Active Directory Domains and Trusts. This snap-in configures and maintains trust relationships and the forest functional level.


  • Active Directory Schema snap-in. This snap-in examines and modifies the definition of Active Directory attributes and object classes. It is the blueprint for AD DS. It is rarely viewed, and even more rarely changed. Therefore, the Active Directory Schema snap-in is not installed, by default.


The demonstration is available at the BryanQA Youtube site

My next VMware exam the VCP-Cloud February 4, 2013

I had intended that my next VMware exam would be the VCAP5-DCD, but at the moment, this is not to be, I have due to my duties as a VCI for a UK national training company decided that my next exam will in fact be the VCP-Cloud

I am extremely fortunate to work for a training company as this means that I have a large amount of kit I can play with, without regard to production systems.

I am also extremely fortunate to be a vExpert as I also have some very useful peers who know the product inside out and upside down.

In order to prepare for my exam I am going to use the tools available to me as a VCI, or in other words, I’m going to use VMware approved training.

As with all VMware certifications, the first place to visit must be the exam blueprint which is available on the VCP-IaaS certification page.

As you will see, even though vCloud 5.1 is now available, currently the exam covers vCloud Director 1.5

The resources I’m using are as follows.

VMware vCloud : Deploy and Manage the VMware Cloud [v1.5]

Also visit the VMware Education site for additional free supplemental courses on Chargeback, vShield and vCloud fundamentals..

Another fantastic resource is Eric Sloof’s brilliant site NTpro , what can I say? This gentleman knows his stuff.

But most importantly I will be installing and configuring a lab environment to supplement my theoretical journey.




I have passed some exams January 11, 2013

Over the last week, I have managed to sit and pass my VMware Certified Advanced Professional v5 (VCAP5-DCA) and also my Microsoft Technology Associate in Networking Fundamentals.

However this year will be quite busy, so watch this space.

Hi all

I’ve changed my blog address to vbry21@wordpress.com, v for virtual. Time to move to the cloud.



What’s new in vSphere 5.1 part 8 September 25, 2012

Posted by vbry21 in Uncategorized.

Auto Deploy was introduced in VMware vSphere 5.0. vSphere Auto Deploy facilitates the rapid provisioning of vSphere hosts by leveraging the network boot capabilities of x86 servers together with the small footprint of the ESXi hypervisor.

Once installed a vCenter host profile is used to configure the host.  After configuration the host is connected to vCenter where it is available to host virtual machines.   The entire process is fully automated allowing new hosts to be quickly provisioned with no manual intervention.

However if we lost the Autodeploy server we lost the ability to boot our hosts

In vSphere 5.1, autodeploy supports:

Stateless or diskless caching host deployments lets you continue operation if the Auto Deploy server becomes unreachable. This was the only mode of install available in vSphere 5.0.

Stateless Caching caches the image when you apply the host profile. When you later reboot, the host continues to use the Auto Deploy infrastructure to retrieve its image. If the Auto Deploy server is not available, the host uses the cached image.

Stateful or disk-backed install:  Lets you obtain the master image from the Auto Deploy Server to quickly and easily install a new host. When you reboot the host, the host boots from disk, just like a host that was provisioned with the installer. Auto Deploy no longer provisions the host.

One of the courses I teach is Site Recovery Manager 5.0, within the course we install, configure and manage vSphere replication; this allows us to replicate and then migrate or failover VMs from our production to our recovery sites without the need of specialist SANs.

Good news is that we now get this functionality natively within VMware vSphere 5.1. With this technology, a virtual machine is replicated by components of the hypervisor, removing any dependency on the underlying storage, and without the need for storage-level replication.

VMs can be replicated between any type of storage platform for example you can replicate between VMFS and NFS or from iSCSI to local disk.  Because vSphere replication works above the storage layer it can replicated independently of the file systems.

Replication is controlled as a property of the VM itself and its VMDKs, eliminating the need to configure storage any differently or to impose constraints on storage layout or management.  If the VM is changed or migrated then the policy for replication will follow the VM.

vSphere replication creates a “shadow VM” at the recovery side, then populates the VM’s data through replication of changed data. This is not however Fault tolerance.

As a Hyper-V trainer and a VMware trainer I look at both products, and one of the nice features of Hyper-V in Windows Server 2012 is the live migration without shared storage, and this led to many questions about “Why don’t VMware have that?” As I’d signed my NDA with VMware I simply said, that at the moment we can’t do this, but now with VMware vSphere 5.1, I can say we do.

Enhanced vMotion enables a VM to change its datastore and host simultaneously, even if the two hosts don’t have any shared storage in common.

Another way of looking at this functionality is supporting VMotion without shared storage.  To use this enhanced functionality the hosts must be connected to the same VMware vCenter and be part of the same datacentre object.  Also the hosts must be on the same layer-2 network.

This vMotion enhancement ensures, zero downtime migration, no dependency on shared storage, and lower operating cost as a SAN is no longer required (but I’d still have one, I really like High Availability).

I’ve made the list as a blogger for VMworld 2012 Barcelona September 21, 2012

Posted by vbry21 in Uncategorized, VMware Training.

Super short blog this one.

I’ve made the list for a VMworld 2012 Barcelona blogger, so lookout for some VMworld 2012 blogs appearing within the next couple of weeks.

If you’re there and you see me say hello, we Geordies (Newcastle people) are friendly people, also I noticed that David Owen of vmackem (Sunderland people) is on the list, so the Northeast of England have two reps at VMworld.
