Thanks to Twitter and Patrick Kremer’s article, I caught the recent news that starting 10 March 2014, VMware will require VCPs to recertify every 2 years to keep their certification current. You can read VMware’s release here. I took the time to read the comment threads on Patricks’ and other’s blogs to get an idea of folks’ reactions. Since you asked, here are my thoughts on the subject.
I shouldn’t have to say that it’s obviously VMware’s prerogative to change or create new policies regarding their certification programs. This shouldn’t be a topic of conversation.
By request, this post is a reproduction of an internal operational document I handed over for the environment in which I installed it.
The Dell Management Infrastructure consists of two dedicated VMs in addition to relying on vCenter and a database. The two dedicated VMs run three separate Dell applications in a Windows Server 2008 R2 VM and a Linux Virtual Appliance. The three applications are Dell OpenManage (OME), Dell Repository Manager (RM), and the Dell Management Plug-in (DMP) Virtual Appliance itself. An overview of the infrastructure is below.
Working for a Cisco VAR, I recently had the opportunity to take the DCUCI exam to meet our Partner requirements. As noted in the title, I took version 5.0 of the exam. I thought I might take a moment and record my thoughts on the exam. As always, I have to stay within the limits set by Cisco’s non-disclosure agreement about test questions and content, but I hope to give someone an idea of what to expect and how best to prepare.
I haven’t recorded my test prep materials before, so here goes my first attempt. It includes a Data Center background in VMware vSphere, Cisco Nexus, and storage, on-the-job experience, lab time and training videos.
Introducing Cisco Data Center Technologies
I’m happy to report that I just passed the second CCNA Data Center exam. I’d like to take a moment and record my thoughts on it.
As many know, the exams went public less than a year ago in December of 2012. I’ve followed those interested in the entire Cisco Data Center program like Tony Bourke (@tbourke) of DataCenterOverlords.com, Chris Wahl (@ChrisWahl) of the WahlNetwork.com, Andy Schmid (@andytschmid) and the PacketPushers.net dudes to get an idea of what to expect. I was also up against a timeline to get CCNA-DC certified in order re-up my CCNA for another three years.
I wanted to take a quick moment to document the awesomeness that is a quick and easy upgrade of Data ONTAP 7-mode with HFS. HFS is a lightweight web server that’s run as an executable and lets you quickly and easily transfer your Data ONTAP images from a Windows machine to the FreeBSD-based NetApp operating system. I can’t take credit for finding this gem of the storage admin. That goes to Mike Mills (@MikeasaService) who found this while we were implementing NetApp systems in a war zone. Thanks, Mike! Of course, if you’re a Mac-man (or gal, but that doesn’t really roll of the tongue as nicely) or a Linux dude, you can easily mount the /etc/software directory using NFS in which case you don’t need a web server. But I digress…on to the steps!
Download Data ONTAP image – from the NetApp Support site (support.netapp.com) and follow the prompts and be sure to download the correct version, in this case, 7-mode
I recently had the opportunity to design and implement NetApp’s entry-level storage solution for a client and I’d like to take this chance to share my approach to the design decisions. One reason for posting this is to help others that may be contemplating similar designs. I know there are a lot of talented and experienced engineers out there that may come across this and I encourage you to comment on this design. I look forward to learning from your experiences and at the same time I hope mine can help others. I should note that the hardware purchased was outside the scope of this design as the decision had already been made, hardware ordered and shipped. Also, common sense says that I’ve changed hostnames and IP addresses to protect the innocent.
The hardware specifications include
|Controller Form Factor||Single enclosure HA; 2 controllers in a 2U chassis|
|Memory||6 GB per controller|
|CPU||Dual Core Intel Xeon C3528 @1.73 GHz, HT enabled|
|Onboard I/O: 6 Gb SAS||2|
|Onboard I/O: 1 GbE||4|
|Mezzanine I/O: 10 GbE||2|
