HP StoreVirtual 4335

May 9, 2016 Graeme Vermeulen 0

I’m a big fan of HP StoreVirtual. It’s a great solution for stretched storage clusters, and I’ve worked on numerous environments with StoreVirtual at the storage layer. Firstly, if you don’t know what StoreVirtual is and how it works: It’s a clustered SAN solution, usually comprising of a minimum of 2x nodes but you can use a single node. They’re actually HP DL3xx servers full of disks; they use HP RAID controllers (normally 4xx series) and the same discrete cards you’d expect to find in servers not running for storage alone. Locally, disks run in RAID (5 for some models, 6 and 10 for others). Volumes that are presented to servers can be configured in “network RAID” such as network […]

Is the VCDX worth it?

May 2, 2016 Graeme Vermeulen 0

I’m a bit of a certification junkie. I love setting goals to get certifications, booking them… and eventually getting that piece of paper that says I know what I’m doing! I do at times ask myself – “is this really worth all the effort?” I hope that if you ask yourself the same question, this post will help. We go to school for ~12 years, learning about subjects that have very little practical application in the real world. We learn important things like spelling, writing – but do we ever learn how to put together a professional email? In fact, we don’t even learn this in University (unless business administration is one of your majors of course). We learn how […]

The VCDX journey so far…

April 28, 2016 Graeme Vermeulen 0

Well, 2016 is just flying by. It’s scary to think that I’ll be 28 this year. Back in February 2014, I decided that I’d be pursuing the VCDX. I mumbled to my boss at the time “I want to get the VCDX after my VCP is done” – I paid for the course and the exam myself, not getting any training or exams paid for me. I signed up for the VMUG Advantage and got a discount, but it still put me out of pocket by a fair bit. Thinking back now, it was the best decision I ever made! Well, I made a commitment that day. A bit over a year later I had completed both my VCAPs, but […]

My VCAP5-DCA Experience

April 24, 2016 Graeme Vermeulen 0

I hope this helps anyone preparing for their VCAP5-DCA or VCAP6-DCV Deploy exam. Preparation: I initially started by going through this guide written by Paul Grevink, working through examples in my lab environment. I’m lucky in that regard as we have a Demo Lab where we get customers in and demonstrate the technology. I look after the lab myself, so I took the opportunity to make sure there weren’t any demo’s coming up and started practicing.   I made sure I had the exam blueprint sitting next to me the whole time and made notes on it as I went along.   After around 3 weeks of solid studying (taking time out between consulting and installs) I found out you […]

I recently had some trouble upgrading the base esxi image on a vmware host running 6.0.0 so thought I would let you all know how I resolved it as I had the same trouble with other hosts running 5.5.0 Going through the usual process of uploading the iso to update manager and creating the baseline completed without any issues and so I migrated all live VM’s to the other host in the cluster, disabled HA on the host and popped it into maintenance mode. When it came to remediating the update I was however faced with the following problem: Now this is a bit of an ambiguous error, so we need to take a look at the logs to find […]

Adding new blades to a C7000 chassis

April 24, 2016 Graeme Vermeulen 0

I recently installed some HP ProLiant BL460c blades into a C7000 chassis. First task was to unbox the blades and install the mezzanine cards: The position of your card depends on which slots you’ve populated at the back. There are 8 slots at the back for your networking, whether you’re using ethernet or fibre cards. Make sure you install the mezzanine card into the corresponding slot, in my case it’s into slot 2. Note – because these are only half-height blades, they only have 2 mezzanine slots each. Full-height blades will have 3. Here’s a guide on port mapping: http://virtualkenneth.com/2012/11/26/understanding-hp-virtual-connect-flexfabric-mappings-with-vmware-vsphere/ Please note that your blades will get their iLO settings from the blade chassis Enclosure Bay IP Addressing configuration, which […]

P2V a server that’s isolated from vCenter

April 24, 2016 Graeme Vermeulen 0

Scenario faced –   My customer has a web server that’s currently hosted in a datacentre. They want to bring this web server in house and use their vSphere platform to host it as a VM, saving around £1000 per month. I have to mention that this is a single web server with no load balancing, it’s an online ordering site that doesn’t experience a high amount of traffic (it’s basically a wholesale ordering site, only certain customers are allowed to buy through it). The server I need to virtualise is in a datacentre, how can I import that into the vSphere environment? There will definitely be downtime, there’s no escaping that. The DC is miles away from the new […]

My VCAP5-DCD Experience

April 24, 2016 Graeme Vermeulen 0

The VCAP-DCD550 is a hard exam. I’d go as far as to say the hardest exam I’ve ever done. Basically, unless you’ve actually worked for a VMware reseller as a designer and had hands-on experience installing and maintaining the technology, it will be a very tough slog indeed. However, even with this knowledge and experience, it’s still a difficult exam to master. Part of the challenge is getting your head around all of the terminology, best practices and VMware’s way of design and implementation. It’s been widely acknowledged that the DCD510 version was easier yet longer, as multiple choice was added to the mix and I also believe you couldn’t go back to review a question once you’d clicked “Next”.
