How To: configure sudo on ESX

Well you have been playing with your console and finally got fedup of typing su – root to get to those esxcfg commands, well you can automate it to do so you need to configure sudo

What the sudo command allows is to let a standard user execute a command as root or another user, as specified in the /etc/sudoers (the config file that defines or list of who can run what) file.

Well you have been playing with your console and finally got fedup of typing su – root to get to those esxcfg commands,  well you can automate it to do so you need to configure sudo

Busy week in the VMware Engineering team

“STOP PRESS” – I was just about to post this and this little nugget appears on VMwareKB

Well it has finally happened after what has seemed an age since the release of vSphere in May.  View 4 has finally arrived,  but wait!  have you noticed one of the pre-reqs,  View required vSphere 4 U1 so now we have to download both View 4 and Update 1 of ESX and vCenter.  this is a significant number of Bits and Bytes. 😀  thank <insert your deity of choice> we are no longer in the days of 28K modems LOL.

So what is all the fuss about 😀 first I will comment on vSphere Update 1

how to remove FT from a host without vCenter

Now before I start, this is not my nugget, I have just added to the process.  So thanks must go to the scripting god that is William Lam.

WARNING: do not do this without Testing first

It is common knowledge that FT (Fault Tolerance) is a feature that comes with vCenter and you will not be able to disable/enable/turn off FT without vCenter. Continue reading “how to remove FT from a host without vCenter”

SRM 4.0 is released and fully supports vSphere and vCenter Linked clones

Well this is post number 100 and it is nice to anounce that VMware have finally released a vSphere compatible version of SRM,  and all I can say is about time.   I could not believe it when vSphere was released int May without SRM support,  that should have been there from day one.  well rant over what VMware goodness does the version 4.0 bring.

Stay of Execution for vSphere Enterprise.

Many of you will remember the ho-har, when during the launch of vSphere,  when they announced that VMware Enterprise Edition was to be retired on the 15 December,   Some people may even remember that I was quite vocal about it.  VMware received quite a lot of negative press about this and the perceived increases in cost for their premier Virtualisation package.   for a good discussion on this read the following thread from the VMware communities:

Enterprise Edition of vSphere was going to be discontinued

Well last night channel partners received news that this position has changed and the Enterprise Edition has received a repreive of its death sentence and its life will now extend beyond the end of 2009. (chalk one up for Tommy Boy 😀 ) on the whole this is great news for customers as there will be no requirement for a forced upgrade when purchasing extra licenses for incumbent installations, and more choice for those customers that do not see the need for vNDS, etc.

The only black cloud on the horizon is that the current “upgrade promotion” concerning Enterprise to Enterprise Plus editions is still scheduled for termination on 15th December 2009, so If you are still on the fence regarding the upgrade remember the clock is ticking.

Linked Clones on vSphere

Well you learn something new every day, thank you to William Lam for this little nugget of infomation

We all know that linked clones in Lab Manager and VMware View have not been supported on vSphere (yes this is slowly changing), well it appears that is not the case! It seems that Linked Clones are available and supported via the vSphere API, have a read of Williams thoughts here:

http://engineering.ucsb.edu/~duonglt/vmware/vGhettoLinkedClone.html

Further, VMware have written a whitepaper on how this black magic (read newly introduced functionality) hangs together, which can be found at:

Linked VM

So while it was perviously true that Linked Clones were only available via Lab Manager and then View, this goodness in now available via scripting to vSphere.

And finally to complete this linked clone goodness William has also writen a couple of scripts to utilise Linked Clones via Service Console/Busybox console for pre-ESX(i) 4.0 which can be found at:

Linked Clones script for ESX 3.x

Linked Clones script for ESXi

The path to Data Centre Zen – Part 1

2 years ago Cisco announced it’s future Data Centre vision “Data Center 3.0”.  Since then we have seen a plethora of products emerge in the marketplace aimed towards the enablement of this vision; the most recent of which is the Cisco Unified Computing System or UCS.  The UCS in perhaps the most powerful and feature rich system released to date, but it is merely part of the bigger picture.

Data Center 3,0 is about far more than just Virtualisation.  It’s goal is to enable IT to become a service, not a cost-centre by making it agile, fast to deploy and easy to manage.  This will enhance end-user experience and enable the network as a platform for collaboration.  There is also a large saving to be made in the running costs of the “Data Center 3.0” model which will please both tree-huggers and bean-counters.

Cisco’s vision is great.  I do not disagree with the principles in the slightest.  The only issue I have is the premium that is paid by the customer and the vendor lock-in.

So my vision for the future is Data Centre Zen.  It is a vendor-neutral architecture with the same underlying principles.
The path to achieving Data Centre Zen is simple:

  • Consolidation
    Consolidation uses a Unified Fabric, which has been enabled through the development of FCoE and loss-less Ethernet (DCE), and CNA’s or Converged Network Adapters that have been developed to consolidate HBAs and NICs.
  • Virtualisation
    Well established solutions are already in place for Server and Desktop Virtualisation but Network Virtualisation is a key part of the overall picture.
  • Integration
    The network must become integrated with VM’s and Applications to be able to dynamically respond to their needs
  • Service Orchestration
    The final step to achieving Zen is enabled though automated provisioning, intelligent network management and integrated security.

Over the coming weeks I will be elaborating on each phase of the model and associated technologies with a view to helping all take one step closer to Data Centre Zen.
