A bit of shameless self promotion for some sessions I'm doing at VMworld and a few others in the BC/DR space that I'm pretty excited by. First, my sessions:
BCO1003 - This is a group discussion, I'll be talking about DR, Site Recovery Manager, vSphere Replication, some best practices; Really this is a general chat about topics in DR that I'll guide, but look to the attendees to take where it makes the most sense. For the last few years these have been focusing more on best practices and capabilities but with a real business oriented twist rather than just pure technology. Find out what your peers are doing in this space and we'll talk about what I've seen in my travels to customers.
BCO4977 - VMware vSphere Replication: Technical Walk-Through with Engineering - This has been a very well attended and reviewed session in the last couple of runs. Aleksey (one of our Staff Engineers in R&D) and I will talk about the inner workings at depth about vSphere Replication, how it works, and really get into the guts of this replication technology including the interplay between VR and SRM. This session is already getting pretty full looking at the attendance numbers!
BCO5129 - Protection for All - vSphere Replication & SRM Technical Update - The highly esteemed Lee Dilworth and I will be talking about what's new this year in VR and SRM, as well as covering some of the topologies that you can use with VR, with SRM, and with the two components together. We'll also cover some best practices for deployment and getting the most success out of these solutions whether you're an SMB or a full blown Enterprise sized company.
BCO5162 - Implementing a Holistic BC/DR Strategy with VMware - Part Two - Jeff Hunter, my friend and colleague in Tech Marketing, and I will be following up with the second half of a two part session where we outline all the various components of VMware's availability toolsets. The first half is put on by our peers in product marketing, and talks about what they do and how they fit together; this second half is the technical portion where Jeff and I will outline how the pieces fit together, what they do, how they interact with one another and add our technical 'colour' to the conversation. I can recommend both part 1 and part 2!
I'll also have some "Knowledge Expert" sessions above and beyond the group discussions, so likely will be parked at the knowledge experts lounge a few times waiting to have a chat, and can also be booked for some one-on-one time for anything relating to BC/DR if you like!
What else is cool in BC/DR at VMworld? Well the sessions I'm most looking forward to are those by my colleagues in product management, product marketing, and tech marketing. A few of those sessions I'm hoping to attend:
After upgrading a vSphere host from ESXi 5.0 to ESXi 5.1u1 I attempted to create an new host profile and was surprised when it failed with the error: "Firewall rule activeDirectoryAll must be enabled for the service lwiod".
This blog posting, like many others, was prompted by a field request from a customer. The customer wanted to understand two things:
- When/How admins were logging into ESXi (DCUI or SSH)
- What were they doing when they were logged in
I am sorry that it took me a while to do this post on VXLAN. I was on summer vacation to India for three weeks and then got busy with the VMworld 2013 preparation. I hope you have registered for VMworld US conference. If you are interested in learning more about network virtualization please checkout the catalogue. I have couple of sessions in the networking track so hope to see you there.
After that shameless promotion about my sessions and before I jump in to explain the vMotion packet flow in VXLAN deployment, I want to address some of the questions that were raised in the comments section of the last blog. Please refer to the diagrams in the blog here.
Recently I installed vCenter Log Insight, which by the way has one of the easiest and intuitive installers and configuration wizards ever!
After the Install and during the configuration you can easily add your vCenter server and vCOPs server so that monitoring can start straight away.
As an extra configuration step you can extend the default logging by setting up each ESXi host to use the Syslog server which is built into Log Insight, the process for this can be found in the documentation located here.
As per the documentation this means either going to each host and configuring the Syslog settings, configuring them manually through the shell or running the configure-esxi script through an SSH session.
As I already had a PowerCLI session open to my environment I wrote a quick PowerCLI script to achieve the same thing, the following script will configure the Syslog settings for each ESXi host to send their events to Log Insight…..
Are you still not registered for VMworld? Why not?!
Let me tell you why I think you should sign up right now and make sure you attend the best event of the year…

Would you like to see new plugins for a specific product or area of your business?
Is there something that bugs you about vCO?
Help us to make your vCO lives better!
As part of the ongoing improvement initiatives at VMware, we would like to collect your feedback through a list of questions in the following areas:
- Your vCO Usage and Plug-in requirements
- Overall feedback and needed enhancements
- Some brief information about your organization
Your feedback is CRITICAL to help us improve vCO and the benefits it can provide to your organization.
Please take a minute to complete all questions as your opinion matters to us.
Thanks for taking the time to make VMware products better!
You likely have already heard of the VMware vCloud Suite. What you might not know is how the products included within the vCloud Suite can be used to solve a specific use case.
To help with this, we've defined some of the common use cases that we find our customers using. If you look here, you'll find a page that describes these use cases and have the opportunity to watch a series of videos that provide a short overview on some of the use cases defined.
You'll also notice on this same page that there is a link to a Hands On Lab (HOL) catalog that contains a series of labs that you can go through, related to the vCloud Suite. Over time, you will see that there will be a lab that corresponds to each of the use cases presented. This is a excellent way to actually see and use the products in action. You can access these HOLs online or at VMworld, if your lucky enough to go.
I know that many of you have reached out in the past about doing ptRDM to ptRDM migrations, especially in situations where you have a storage array refresh taking place in your environment. A ptRDM is a physical compatibility mode raw device mapping, to give it its full name. It is also known as a pass-thru RDM, in so far as we allows the virtual machine to issue ANY kind of I/O to the LUN. A whole bunch of comments requesting a feature like this appeared in the comments section of an RDM article I did last year. Obviously the ability to move those ptRDMs from one array to another array would be very desirable in those situations. I have taken this request for a ptRDM to ptRDM migration tool to our product managers and our engineering teams. This article will try to explain how it is impossible to create such a tool.
Recently there have been a number of queries in and around Storage I/O Control (SIOC) I/O accounting, especially when it comes to what might be called administrative functions such as virtual machine snapshots and Storage vMotion. I'll try to answer some of those frequently asked questions in this post.
