This year I’ve been working on a VMware design for a large enterprise customer, and had various conversations with the solutions team on everything from storage sizing to networking (that was one day!). This prompted me to address one topic that I feel deserves more attention, and that is the Cisco Nexus 1000V. If you are new to the 1000V virtual switch, then you might want to read the guide I published back in April 2012 on How to Deploy the Cisco Nexus 1000V. For now, grab a coffee and let’s begin with load-balancing policies… [Read more…] about Cisco Nexus 1000V NIC Teaming and Load Balancing
Today I took the VCP510 exam and passed, so I thought I would share my thoughts on this latest certification by VMware. Firstly, I’m in the middle of the VCAP exams, having just completed the VCAP-DCA4 and will soon start studying for the VCAP-DCD4. Why take the VCP exam based on a new version now? Well, mainly because I’ve already been on the VMware vSphere: What’s New [V5.0] course and most of the contents are still fresh in memory. Secondly having passed the VCAP-DCA4 exam, with the next one being design focused I can pretty much focus on design best practices regardless of the version (although there are obvious differences).
After spending a week working down-under in Perth, I managed to get some time off this week to recover from the jet lag, so what better way than spending a few days refreshing my memory and doing LOTS of lab work with vSphere 5!
Much of my focus was around the vSphere Storage Appliance (vSA), vCenter Server Appliance and Auto Deploy and I must admit after reading some other comments I didn’t focus too much on configuration maximums (still glanced over them).
I can’t go into the specifics of the exam, as per the usual NDA, but here are my thoughts… [Read more…] about VCP5 (VMware Certified Professional on vSphere 5) VCP510 Exam Experience… I passed!
If you are looking to deploy multiple ESX/ESXi servers then there are plenty of methods and tools out there, some more complex than others. There are vendor specific deployment products available such as HP Rapid Depuployment Pack (RDP) which uses Altiris, or alternatively there are free deployment tools such as ESX Deployment Appliance (EsleeDA) and Ultimate Deployment Appliance (UDA). UDA is my favorite tool for the job as it offers great flexibility such as the use of subtemplates (discussed later), and therefore this will be the basis of this article. It was created by Carl Thijssen and thanks to Mike Laverick of RTFM, it also supports ESX/ESXi deployments, and the latest build supports ESX/ESXi 4.1.

In this article I detail the steps required to configure your vMA as a Syslog server, and configure your ESX/ESXi hosts to send logging information to the vMA. Logging is often overlooked, but when managing multiple hosts it is far easier to send your logs to a Syslog server. I’m studying for the VCAP-DCA exam, and using vicfg-syslog is a requirement of the exam (Section 6.1) and the vMA is also essential to understand (Section 8.1). I hope my notes help you as they have helped me.

VMware have released vSphere 4.1 Update 1 which adds support for additional operating systems (RHEL 6, RHEL 5.6, SLES 11 SP1 for VMware, Ubuntu 10.10, and Solaris 10 Update 9). ESX/ESXi 4.1 Update 1 now supports 160 logical processors. Looking at the number of patches for ESX and ESXi below, it makes me wonder whether this will be the last release of ESX, in favour of ESXi?
