VMware – VMworld 2019 – Wrap-Up And Link-O-Rama

Disclaimer: I recently attended VMworld 2019 – US.  My flights and accommodation were paid for by Digital Sense, and VMware provided me with a free pass to the conference and various bits of swag.

A quick post to provide some closing thoughts on VMworld US 2019 and link to the posts I did during the event. Not in that order. I’ll add to this as I come across interesting posts from other people too.

Wrap-up

This was my fourth VMworld US event, and I had a lot of fun. I’d like to thank all the people who helped me out with getting there, the people who stopped and chatted to me at the event, everyone participating in the vCommunity, and VMware for putting on a great show. I’m looking forward to (hopefully) getting along to it again in 2020 (August 30 – September 3).

VMware vSphere and NFS – Some Links

Most of my experience with vSphere storage has revolved around various block storage technologies, such as DAS, FC and iSCSI. I recently began an evaluation of one of those fresh new storage startups running an NVMe-based system. We didn’t have the infrastructure to support NVMe-oF in our lab, so we’ve used NFS to connect the datastores to our vSphere environment. Obviously, at this point, it is less about maximum performance and more about basic functionality. In any case, I thought it might be useful to include a series of links regarding NFS and vSphere that I’ve been using to both get up and running, and troubleshoot some minor issues we had getting everything running. Note that most of these links cover vSphere 6.5, as our lab is currently running that version.

Basics

How to add NFS export to VMware ESXi 6.5

Best Practice

Troubleshooting

Maximum supported volumes reached (1020652)

Dell Technologies World 2018 – Wrap-up and Link-o-rama

Disclaimer: I recently attended Dell Technologies World 2018.  My flights, accommodation and conference pass were paid for by Dell Technologies via the Press, Analysts and Influencers program. There is no requirement for me to blog about any of the content presented and I am not compensated in any way for my time at the event.  Some materials presented were discussed under NDA and don’t form part of my blog posts, but could influence future discussions.

Here’s a quick post with links to the other posts I did surrounding Dell Technologies World 2018, as well as links to other articles I found interesting.

Conclusion

I had a busy but enjoyable week. I would have liked the get to more of the technical sessions, but being given access to some of the top executives in the company via the Press, Media and Influencers program was invaluable. You might have also noticed that the product announcements weren’t as abundant as in previous years. People inside Dell Technologies tell me this is because there’s been a lot more focus on making sure things are working before they announce (or ship) products. Thanks again to Dell Technologies (particularly Debbie Friez and Konnie) for having me along to the show. Now, please enjoy this picture of my good friend Jon Klaus at the Customer Appreciation Party.

VMware – Deploying vSphere Replication 5.8

As part of a recent vSphere 5.5 deployment, I installed a small vSphere Replication 5.8 proof-of-concept for the customer to trial site-to-site replication and get their minds around how they can do some simple DR activities. The appliance is fairly simple to deploy, so I thought I’d just provide a few links to articles that I found useful. Firstly, esxi-guy has a very useful soup-to-nuts post on the steps required to deploy a replication environment, and the steps to recover a VM. You can check it out here. Secondly, here’s a link to the official vSphere Replication documentation in PDF and eBook formats – just the sort of thing you’ll want to read while on the treadmill or sitting on the bus on the way home from the salt mines. Finally, if you’re working in an environment that has a number of firewalls in play, this list of ports you need to open is pretty handy.

One problem we did have was that we’d forgotten what the password was on the appliance we’d deployed at each site. I’m not the greatest cracker in any case, and so we agreed that re-deploying the appliance would be the simplest course of action. So I deleted the VM at each site and went through the “Deploy from OVF” thing again. The only thing of note that happened was that it warned me I had previously deployed a vSphere Replication instance with that name and IP address previously, and that I should get rid of the stale version. I did that at each site and then joined them together again and was good to go. I’m now trying to convince the customer that SRM might be of some use to them too. But baby steps, right?

Note also that, if you want to deploy additional vSphere Replication VMs to assist with load-balancing in your environment, you need to use the vSphere_Replication_AddOn_OVF10.ovf file for the additional appliances.

Storage – Erasure Coding and RAID – A Few Good Links

Erasure coding has been around for a little while now, and if you’ve ever sat through a presentation from a cloud storage provider talking about resiliency of data at scale, you may have heard it mentioned. It occurred to me that I’ve just assumed that people know what it is, and that’s not fair. I was going to do a post explaining what it is, but figured a quick post with some links to some articles I found of use would be more useful. Because what’s the point of the internet if I can’t be lazy and link to things on it?

Here’re some useful research papers to start with:

The “press” also has some useful articles on the topic. I recommend you have a look at these two:

Some of my preferred analysts have written a bit on the topic:

Josh has also done a great deep-dive on the Nutanix version of erasure coding (EC-X) that you can see here.

My favourite post, though, is this one: Dummies Guide to Erasure Coding.
