Looking back at a VMware VDI Deployment

My good friend Nathan Bryne wrote a good post about “Do I really need to do a Desktop Assessment?“, which got me thinking.

I worked at a college for around 3 years where we had a 1000 seat VMware View VDI deployment. I started working there just after the college had decided to go all-in on VDI and purchased the equipment, as most of their student machines were getting to 5 years old, and in some areas 7 years old.

The highlights of this were;

HP-AMS Driver causes ESXi memory leak

So basically I had a customer hit by a known HP-AMS driver issue (KB2085618), the symptons were as follows;

  • Unable to vMotion a VM to another host, gives “operation timed out error”

2014-11-10_10-36-15

  • If power off VM, vMotion a machine to another host, and then power on, you get the following error “Could not start VMX: msg.vmk.status.VMK_NO_MEMORY”

ESXi memory leak

This issue is caused by a memory leak in the driver which fills the SWAP memory of the ESXi host, making it unable to response to any requests at all,

For example, trying to enable SSH;

Veeam upgrade to v8 – Enterprise Manager fails with Access Control List error

So the other day I blogged about the Veeam v8 upgrade, and as mentioned my Enterprise Manager didn’t work, giving the error;

The Access Control List is not in canonical form and therefore cannot be modified.

Veeam v8 is here – New Features and Upgrade Process

So Veeam’s High Availability Suite is here!!!! Basically v8.

So in this post we are looking at Features and the upgrade of the program, and using the program when updated.

New Features
Backup and Replication

My favourite feature which doesn’t seem to be in the documentation online, is Snapshot Hunter, where Veeam actively looks for and removes any snapshots which havent deleted properly, i.e where vCenter said snapshot removed, and it hasn’t!!!

High-Speed Recovery
• Veeam Explorer for Microsoft Exchange, SharePoint, SQL Server and
Active Directory: Granular-level recovery and low recovery time objectives (RTOs) Continue reading Veeam v8 is here – New Features and Upgrade Process

How to produce good documentation – Part 2 – Rack and Server Diagrams

Oh no, diagrams! But, but, I’m not creative!

So we covered the foundation an environment in part 1, which is that hated word, which is documentation,

But that means you need diagrams, which is something most people struggle with, especially using Visio.

You’re not alone, I was the same, my documentation in my early days was shocking, and then I took on a consultancy role, where I was implementing solutions and having to produce documentation for customer. I had a steep learning curve.

So I’m going to take you into the first steps on how to diagram your Racks and the servers in them.

Visio and your stencils

So your going to need Visio, preferably 2013, but 2010 will be fine. And you need stencils of the hardware you’re creating a diagram of.

The best place to get 90% of your Visio Stencils is VisioCafe.

For others that do not appear on there, its easy enough to just google the vendor name plus Visio ;).

Here’s the file for the Visio diagrams.

Creating a diagram of your rack

So this is something I do for most of my customers, creating a diagram of the rack, mainly to show the bits I’ve stuck in, and so the customer knows which server is which, and then can refer to the rest of the document for what that bit of kit does.
