So, this one’s probably a bit pedestrian, but it sets up nicely for the next demo I have planned. Stay tuned over the next couple of days where I show you how to upgrade ESXi 5.1 to ESXi 5.5 with vSphere Update Manager.
I know it’s not the most exciting thing, and most have probably been through this more than once, but I put together a demo of installing ESXi 5.5, along with a tour of the DCUI.
EDIT: The video was refreshed thanks to a colleague pointing out some audio issues
It’s been well over a year since I’ve been here (well, closer to 18 months, really). I’ll apologize for that now 🙂
The reality, though, is that it’s been a long, exhausting, and rewarding year and a half, and I’ve taken on some different responsibilities at work. That’s taken up quite a bit of my time. I decided I just needed to roll some of that time together with this blog. Well, at least some of the fruits of that work.
We’ve just released the latest, greatest version of vSphere – vSphere 5.5 With a new version comes a need to upgrade.
Some of you may be using the vCenter Server Appliance. There’s an Update feature in the appliance to help update from one version to another. But right next to that in the management UI is a tab called Upgrade. And that’s the process I’ve just stepped through for you. Keep in mind here that I haven’t read any of the upgrade KBs (shame on me), but this is a relatively intuitive process, I think.
Take a look at the video – it’s about 20 minutes long – some time has been shaved off; the entire process took me about an hour, but you don’t want to watch a bunch of silence and spinning wheels, do you? I didn’t think so.
I will throw out a caveat (that I didn’t show onscreen) that I did have to regenerate the self-signed certificates before the Web Client worked properly.
Test this process extensively before you try this in a production environment!! Please, don’t try this blindly!
I learned quite a bit during this process, and I hope it helps you a bit.
I’m a happy camper! My new lab gear is in.
I believe we all need some kind of lab environment to play with, otherwise we just don’t learn the hands-on stuff nearly as well or as quickly. Some employers have lab environments in which to test. My employer is no different, but I prefer to have control over what I deploy, and when I deploy it. That way I have no one to blame about anything but myself 🙂
That said, I was running my lab in an old Dell Precision 390 with nothing but 4 cores, 8GB of RAM, and local storage. That was great a couple of years ago when I put it together, but now, not so much.
The new gear is actually server-grade stuff. And reasonably inexpensive, if you ask me.
For my storage, I stumbled on a great deal on a N40L Proliant MicroServer from HP. after repurposing some disk I had laying around the house, I had a small, reasonable storage server. I installed a bunch of SATA disk: 3 7200 RPM 500GB spindles and a 1TB 7200 RPM spindle in the built-in drive cage. But that wasn’t quite enough for what I had in mind. So I bought an IcyDock 4-bay 2.5″ drive chassis for the 5.25″ bay in the MicroServer, and added an IBM M1015 SAS/SATA PCI-e RAID controller to drive the 2.5″ devices. I had an Intel 520 Series 120GB SSD (bought for the ESXi host, but it didn’t work out) and a WD Scorpio Black 750GB drive just hanging around. So I added another SSD and Scorpio Black so I could mirror the devices and have some redundancy.
So there’s my SAN and NAS box. I installed FreeNAS to a 16GB USB stick, and carved up 4 ZFS pools – platinum, gold, silver, and bronze. Creative, I know LOL.
- Platinum is a ZFS mirror of the 2 SSDs
- Gold is a RAID-Z set of the 3 500GB spindles
- Silver is a ZFS mirror of the 2 Scorpio Blacks
- Bronze is a ZFS volume on the single 1TB spindle
I debated on swapping Gold and Silver at length, but in the end, left the layout as described.
There are two things I don’t like about this setup, and they both revolve around the networking baked into the MicroServer.
- Jumbo Frames aren’t supported by the FreeBSD driver for the onboard BroadCom NIC. This could be fixed in the future with a driver update or the official release of FreeNAS 8.2 (I’m running beta 2 at the moment)
- There’s only one onboard NIC. I’d have liked two NICs, but for the price, maybe I’ll add a PCI-e dual-port Intel Gig card. That would solve both dislikes.
Platinum, Gold, and Silver are presented via the iSCSI Target on the FreeNAS box as zVol extents. Bronze is shared via NFS/CIFS, primarily for ISO storage.
As for the ESXi host itself, well here we go:
- ASUS RS-500A-E6/PS4 chassis
- 2 x AMD Opteron 6128 8-core CPUs
- 64GB of Kingston ECC RAM
- 250GB 7200RPM spindle from the MicroServer
- 1TB 7200RPM spindle that was recycled from the old lab gear
I chose this seemingly overpowered setup for a few reasons (yep, another bullet point list)
- Price (the server and its constituent parts only ran me ~$2100USD)
- Nearly pre-assembled. I’m not one for building machines anymore
- Capacity. Instead of running multiple physical ESXi hosts, I chose to run my lab nested.
- Compatibility. This server’s Intel counterpart is on the VMware HCL. That didn’t mean this one would work, but I felt the odds were high. The onboard NICs are also both Intel Pro 1000s, which helps.
- LOM was included. This is important to me, as I don’t want/need/have tons of extra monitors/keyboards hanging around
So all the parts came in, I put them installed the disks, CPUs, and RAM, dropped an ESXi CD in the drive, booted it up, and wondered – where’s the remote console? I hadn’t thought about that, so I jacked in a monitor and keyboard only to find that the Delete key is necessary to get into the BIOS to configure the iKVM. Well, in my case, that posed a little bit of a problem. See, the only wired keyboards (or wireless, for that matter) are Apple keyboards, since I recently let the last physical Windows box leave my house. So I had to see if the iKVM pulled DHCP. I got out iNet, my trusty Mac network scanning utility, scanned my network, and there it was – a MAC address identifying as “ASUSTek Computer, Inc”. That had to be it, so I fired up a web browser and plugged in the IP. Now I just had to figure out the username and password. Documentation to the rescue! So I got everything configured up, and booted to the ESXi installer, and there you have it, one nice, 16-core 64GB of RAM ESXi host.
Well, this is probably one of the most delayed “Welcome to the new year” posts so far.
I have been _busy_. This is one of my few quiet weekends since, well, I’m not sure I remember, but even this weekend’s almost over. I mentioned on Google+ that I’m taking my VCAP5-DCD tomorrow. I’ll talk about that experience later 🙂
After that, I fly to California for a couple of days of team meetings. I guess I’ll get to see what our new leadership has in store for us crazy instructors this year. I’m definitely looking forward to seeing my fellow instructors, and meeting the new management, including the Delivery Manager I’ve been working with for almost 75 days now!
Life and work have both been keeping me hopping, as evidenced by my lack of content here. I’ve got all kinds of ideas, drafts started, thoughts jotted down. Maybe I’ll get to them, maybe you’ll just have to come to one of my classes to get some of my insights (which, arguably, aren’t all that insightful – I’ve been cognizant of the fact that every day I’m an instructor is one more day deeper into that ivory tower of technology). But I still try to share things that are important to me.
So keep me in your RSS feed, I’ll drop something interesting in once in a while, but this year is getting off to a rather slow start in the same way last year sort of tapered off to nothing. I’m trying here! 🙂
Well, they finally let the cat out of the bag! A couple of months ago now, I took a day trip down to Martin, Tennessee to sit the VCP5 Beta exam.
After a few trials and tribulations getting there (remember all the flooding in the midwest earlier this year?), and them more challenges once I got to the testing facility (one of the other testing software packages didn’t much get along with the Pearson packages), I finally got to sit the exam. I made it to the facility on time, but with the system problems, it was another 30-45 minutes of waiting before I could actually participate in the exam.
And _wow_ it was long! And challenging! This isn’t your father’s VCP exam, assuming most of the questions make it to the final product. This exam was all about understanding – the product, it’s use cases, everything. This new generation of VCP will be the sharpest yet (and I think that’s saying something – we’ve had some great exams over the years), and VMware is doing a great job of keeping the value of the VCP at a premium level.
The VCP5 is not a data-regurgitation exam, not can it be explicitly taught. VMware still has the Install, Configure, Manage requirement if you hold no VCP. But the class is not going to teach you the exam, just like it’s been since I got into this VMware thing in 2006. It will, however, provide you with a good foundation with which to start.
If you’re a current VCP4, you can sit the exam with no class requirement until February 29, 2012.
Oh, and I”m writing all this because I finally got my VCP5 exam results. I passed! That makes the whole trip to Tennessee and all its trials worth it!
All the cool stuff I have in the works (vCoud Directory 1.5, the rest of the AutoDeploy stuff, and more) is on hold for the moment. My time is being consumed by a couple of custom classes I’ve got to develop and run. Pretty much, September is shot 🙂 Of course, October may or may not be much better, with new classes coming up (here’s to me agreeing to be a lead instructor lol)
It’s all still coming, and I will probably not be the first to discuss most of the topics, but I will get the info up. It’ll be a heck of a lot easier to do all this after I can get some dedicated ESXi hosts early next year. In the meantime, VMs still fit on the iMac and the old workhorse Precision.
I’ll still be around, just not as online as I have been.
