Veeam Offers Free NFR License for Backup & Replication v6

December 23rd, 2011

Veeam is once again blessing the community with their generous holiday spirit, which of course includes gifts!  Veeam recently launched version 6 of their flagship Backup and Replication product which now includes support for Microsoft Hyper-V.  Those who are heavily active in the Microsoft and/or VMware community and formally recognized as such, are eligible to register for their free gift from Veeam – NFR licensing for Backup and Replication v6. 

I will attest that I’ve been using Veeam Backup & Replication to protect valuable data in my home lab for a few years and I’ve had to rely on it for recovery more than once.  I also included it as a backup and disaster recovery replication solution in my VCDX design submission which I successfully defended in February 2010.

Below you’ll find two promotions for redeeming the NFR licenses.  First is the Hyper-V promotion for MVPs, MCPs, and MCTSs, followed by the VMware promotion for vEXPERTs, VCPs, VCIs, and registered VMUG members (remember, anyone can be a registered VMUG member, it’s free to sign up, so why not do it today?)

VMworld 2011 Hands On Lab Posters

December 15th, 2011

If you were at VMworld 2011 US and/or Europe, you may have seen or heard of the posters being given away at the Hands On Labs.  Supplies were limited at the US conference and if you attended in Copenhagen maybe you didn’t get a chance to get into the labs to grab some posters.

Although VMworld is over, you still have access to the posters.

One way would be to request a Dell Compellent Executive Briefing with me. I brought a few pounds of posters back from Copenhagen and what’s mine is yours if you’re willing to listen to me talk about the great integration points Dell Compellent Storage Center has with VMware’s growing portfolio.

The other option would be to go online and grab a copy of the posters which you can view electronically or have printed at your local copier shop.  This blog post was inspired by Xtravirt email bulletin 94 – thanks for pulling together the links guys.

Cloning VMs, Guest Customization, & vDS Ephemeral Port Binding

November 25th, 2011

I spent a lot of time in the lab over the past few days.  I had quite a bit of success but I did run into one issue in which the story does not have a very happy ending.

The majority of my work involved networking in which I decommissioned all legacy vSwitches in the vSphere 5 cluster and converted all remaining VMkernel port groups to the existing vNetwork Distributed Switch (vDS) where I was already running the majority of the VMs on Static binding port groups.  In the process, some critical infrastructure VMs were also moved to the vDS including the vCenter, SQL, and Active Directory domain controller servers.  Because of this, I elected to implement Ephemeral – no binding for the port binding configuration of the VM port group which all VMs were connected to, including some powered off VMs I used for cloning to new virtual machines.  This decision was made in case there was a complete outage in the lab.  Static binding presents issues where in some circumstances, VMs can’t power on when the vCenter Server (Control Plane of the vDS) is down or unavailable.  Configuring the port group for Ephemeral – no binding works around this issue by allowing VMs to power on and claim their vDS ports when the vCenter Server is down.  There’s a good blog article on this subject by Eric Gray which you can find here.

Everything was working well with the new networking configuration until the following day when I tried deploying new virtual machines by cloning powered off VMs which were bound to the Ephemeral port group.  After the cloning process completed, the VM powered on for the first time and Guest Customization was then supposed to run.  This is where the problems came up.  The VMs would essentially hang just after guest customization was invoked by the vCenter Server.  While watching the remote console of the VM, it was evident that Guest Customization wasn’t starting.  At this point, the VM can’t be powered off – an error is displayed:

Cannot power Off vm_name on host_name in datacenter_name: The attempted operation cannot be performed in the current state (Powered on).

DRS also starts producing occasional errors on the host:

Unable to apply DRS resource settings on host host_name in datacenter_name. The operation is not allowed in the current state.. This can significantly reduce the effectiveness of DRS.

VMware KB 1004667 speaks to a similar circumstance where a blocking task on a VM (in this case a VMware Tools installation) prevents any other changes to it.  This speaks to why the VM can’t be powered off until the VMware Tools installation or Guest Customization process either ends or times out.

Finally, the following error in the cluster Events is what put me on to the suspicion of Ephemeral binding as the source of the issues:

Error message on vm_name on host_name in datacenter_name: Failed to connect virtual device Ethernet0.

Error Stack:

Failed to connect virtual device Ethernet0.

Unable to get networkName or devName for ethernet0

Unable to get dvs.portId for ethernet0

I searched the entire vSphere 5 document library for issues or limitations related to the use of Ephemeral – no binding but came up empty.  This reinforced my assumption that Ephemeral binding across the board for all VMs was a supported configuration.  Perhaps it is for running virtual machines but in my case it fails when used in conjunction with cloning and guest customization.  In the interim, I’ve moved off Ephemeral binding back to Static binding.  Cloning problem solved.

Link Layer Discovery Protocol (LLDP)

November 17th, 2011

Several months ago I co-wrote a piece titled Cisco Discovery Protocol (CDP) Tag Team.  The article talks about CDP, walks through some working examples, and provides a view of what information the protocol advertises.  CDP is a great tool but it’s proprietary to Cisco network gear.  In the past, if you were using non-Cisco switches, you couldn’t leverage CDP in either direction (listen or advertise).

Today is the first look at a new vSphere 5 networking feature which is Link Layer Discovery Protocol – essentially CDP for every other switch vendor which supports this IEEE 802.1AB open standard.

Take a look at the images below which show a side by side comparison of LLDP and CDP from the vSphere Client perspective:

As you can see, there’s a lot of parity between the two protocols.  Each provides some very helpful information from the upstream physical network perspective.  Namely the identification of the switch and the port number.  From what I’ve seen so far, LLDP is a completely viable alternative to CDP.

In case you’re wondering where to configure LLDP or CDP on a vNetwork Distributed Switch, it’s an advanced setting of the vDS itself:

vSphere 5 Configuration Maximums Updated For The Cloud

November 11th, 2011

A few nights ago, Chris Colotti and Dave Hill presented a vCloud Architecture Deep Dive brown bag session.  Among the tips I picked up in that session was a comment from Chris that my most favorite VMware document of all time had been updated within the last 6 weeks – vSphere 5 Configuration Maximums.  Basically what was added was the inclusion of vCloud Director configuration maximums:

Item Maximum
Virtual machine count 20,000
Powered‐On virtual machine count 10,000
Organizations 10,000
Virtual machines per vApp 64
vApps per organization 500
Number of networks 7,500
Hosts 2,000
vCenter Servers 25
Virtual Data Centers 10,000
Datastores 1,024
Catalogs 1,000
Media 1,000
Users 10,000

If you’ve been following the progression of this document, you will have noticed that VMware has been adding more application layer components to it.  That is because VMware has broadened its cloud platform portfolio which is fundamentally dependent on vSphere.  Chris mentioned this in his lecture and I began noticing it a few years ago, vCenter now extends beyond just a tier 2 management application.  It has become a tier 1 cornerstone for other VMware and partner ecosystem cloud applications and infrastructure tools.  Be mindful of this during the design phase and do not neglect its resource and redundancy requirements as your scale your vCloud environment.

Enjoy.  And by the way, Chris has a Dell T310 Server with 20GB RAM for sale.  Check it out.

Add ESXi to an Active Directory OU

November 10th, 2011

While working with vSphere 5 and vCloud Director, I stumbled onto a piece in the vSphere Client Help files that I haven’t seen in previous versions of vSphere (or maybe it existed and I wasn’t aware).  That is, the ability to add an ESXi host to a specific Organizational Unit above and beyond adding it to Active Directory.  VMware ESXi Active Directory integration has gotten much easier once they partnered with Likewise.  In vSphere 4 if I wanted an ESXi computer account to drop into a specific OU, I pre-created the computer account before the ESXi host to the domain.  In vSphere 5, the ESXi host can be joined to the domain and placed into an explicit OU all in the same step.

Say for example I wanted my esxi5 computer account to be placed into the boche.mcse domain in an OU path of /Lab/Servers as shown below:

I can accomplish this now by providing the full path in the Domain field as shown below:

The result is that the esxi5 computer account is now placed in the desired OU hierarchy:
