Random Short Take #107

Random short take #107. Looking for old news? I’ve got just the thing. Let’s get random.

  • This article from Matt Allford struck a chord. I have an awful lot of USB cables in my house, and I have no idea what the specs of most of them are.
  • Speaking of things I only have a superficial understanding of, this article from Christian on Intel Arc SR-IOV hardware transcoding with Plex on Proxmox VE was great.
  • Still using an Apple Time Capsule? You’re out of luck and in luck at the same time, as is explained over at The Register.
  • Speaking of backup and recovery, this article about Backblaze has me questioning everything I’m doing to keep stuff safe at home. I’ve checked that my iCloud data is protected (and recoverable), but only because the machine I have Backblaze installed on has downloaded copies of that data. For the stuff I keep on Dropbox and Google Drive, it doesn’t seem as straight forward. Not that I’d ever recommend you only keep data with one provider. Maybe I need to write something more about this, if only to confirm that I’m doing correctly myself.
  • In resilience news (is that really a category?), this was an interesting article on AWS and what’s happening in the Middle East. The response from AWS has been fascinating, as have some of the hot takes from so-called “disaster recovery experts”. I’m looking forward to talking with customers in Western Queensland about the risk matrix they’ve drawn up that has them in a tizzy about losing three availability zones. There’s preparedness and then there’s how you recover, I guess.
  • Missing using FireWire with the most recent version of macOS? This article from Jeff Geerling might be of use if you still have a MiniDV camera you need to connect to something. It just won’t be with macOS.
  • Speaking of things not working after updates, you could always follow John Birmingham’s advice and just never update. But I’m not sure that’s really sustainable.
  • I think Netflix does some really cool stuff from a technical perspective, but for the most part the catalogue seems to be trash. So these kinds of posts from people rediscovering physical media are always nice to read.

Amazon Web Services – Elastic VMware Service – A Few Notes …

Posted on by

Amazon Web Services (AWS) recently announced the general availability of its Elastic VMware Service (EVS). This is a brief post covering what the service is, how it can be consumed, and why it might be of interest.

 

What Is It?

EVS is a service that provides the ability to run VMware Cloud Foundation (5.2.1) on AWS bare-metal instances (specifically I4i.metal). It’s a by-the-book consolidated architecture (running management and workload domains together), and contains the following VCF management components:

  • ESXi hosts;
  • vCenter Server instance;
  • SDDC Manager;
  • vSAN datastore;
  • Three-node NSX Manager cluster;
  • vSphere cluster; and
  • NSX Edge cluster.

Storage is provided by vSAN (and selected third-party storage integrations), with two discrete network layers being delivered: the Amazon VPC and the VMware NSX overlay network. You can read more about the architecture here.

To consume the service, you’ll need 4 nodes to get started, along with at least 2 VPC Route Servers, and AWS Enterprise Support. There’s a pricing calculator on the AWS website. You’ll also need to procure VCF licensing from Broadcom or an authorised reseller.

 

Where Is It Available?

The initial launch Regions are:

  • US East (North Virginia)
  • US East (Ohio)
  • US West (Oregon)
  • Asia Pacific (Tokyo)
  • Europe (Frankfurt)
  • Europe (Ireland)

Availability in more Regions is planned for the future.

Other Considerations

Storage

You can leverage NetApp’s FSx for NetApp ONTAP service to provide additional storage for the cluster. There’s some useful guidance here and here. If you like it more orange, Pure Storage’s Cloud Block Store is also available for use with EVS. You can read that announcement here.

Clusters

Cluster sizes are currently limited to between 4 (minimum) and 16 (maximum) nodes. There is currently no support for stretched clusters. This will likely change in the future.

Add-ons

Services that VMware Cloud on AWS users may be familiar with, such as vDefend Advanced Threat Protection, and VMware Live Cyber Recovery, are not currently available with EVS.

Planning and Deployment

Much like VMC on AWS (and most other cloud service deployments, for that matter), there’s a bit of planning you’ll need to do before you jump on the console. There’s a handy checklist that takes you through all of the requirements here. It’s also worth noting that, unlike VMC on aWS, this isn’t a managed service, so some of the VPC constructs you see with VMC on AWS aren’t used with EVS. For example, there’s no shadow VPC deployed for EVS – it’s all done out of the customer account. And features like EDRS aren’t available, you need to manage your capacity yourself, in much the same way as you would do with an on-premises VCF deployment.

 

Thoughts

EVS is the same as VMC on AWS in the sense that it’s running VMware software on top of AWS bare metal servers. There are plenty of differences though, some of which I’ve covered above. I imagine many of the constraints around additional product integrations and scalability will be removed in the near future as the product evolves, and we’ll no doubt see some changes when it comes to partners offering managed services wrapped in with EVS. It’s been a while coming, but now that it’s here, I’m interested to see how the market responds. There are probably plenty of questions I haven’t answered, but there’s a useful FAQ document here.

Happy New Year. Let’s get random.

  • Excited about VMware Cloud Director releases? Me too. 10.3.2 GA was recently announced, and you can read more about that here.
  • Speaking of Cloud Director, Al Rasheed put together this great post on deploying VCD 10.3.x – you can check it out here. 
  • Getting started with VMware Cloud on AWS but feeling a bit confused by some of the AWS terminology? Me too. Check out this extremely useful post on Amazon VPCs from a VMware perspective.
  • Still on VMware Cloud on AWS. So you need some help with HCX? My colleague Greg put together this excellent guide a little while ago – highly recommended. This margarita recipe is also highly recommended, if you’re into that kind of thing. 
  • Speaking of hyperscalers, Mellor put together a nice overview of Hyve Solutions here. 
  • Detecting audio problems in your home theatre? Are you though? Tom Andry breaks down what you should be looking for here.  
  • Working with NSX-T and needing to delete route advertisement filters via API? Say no more. 
  • Lost the password you set on that Raspbian install? Frederic has you covered. 

Random Short Take #65

Welcome to Random Short take #65. Last one for the year I think.

  • First up, this handy article from Steve Onofaro on replacing certificates in VMware Cloud Director 10.3.1.
  • Speaking of cloud, I enjoyed this article from Chris M. Evans on the AWS “wobble” (as he puts it) in us-east-1 recently. Speaking of articles Chris has written recently, check out his coverage of the Pure Storage FlashArray//XL announcement.
  • Speaking of Pure Storage, my friend Jon wrote about his experience with ActiveCluster in the field recently. You can find that here. I always find these articles to be invaluable, if only because they demonstrate what’s happening out there in the real world.
  • Want some press releases? Here’s one from Datadobi announcing it has released new Starter Packs for DobiMigrate ranging from 1PB up to 7PB.
  • Data protection isn’t just something you do at the office – it’s a problem for home too. I’m always interested to hear how other people tackle the problem. This article from Jeff Geerling (and the associated documentation on Github) was great.
  • John Nicholson is a smart guy, so I think you should check out his articles on benchmarking (and what folks are getting wrong). At the moment this is a 2-part series, but I suspect that could be expanded. You can find Part 1 here and Part 2 here. He makes a great point that benchmarking can be valuable, but benchmarking like it’s 1999 may not be the best thing to do (I’m paraphrasing).
  • Speaking of smart people, Tom Andry put together a great article recently on dispelling myths around subwoofers. If you or a loved one are getting worked up about subwoofers, check out this article.
  • I had people ask me if I was doing a predictions post this year. I’m not crazy enough to do that, but Mellor is. You can read his article here.

In some personal news (and it’s not LinkedIn official yet) I recently quit my job and will be taking up a new role in the new year. I’m not shutting the blog down, but you might see a bit of a change in the content. I can’t see myself stopping these articles, but it’s likely there’ll be less of the data protection howto articles being published. But we’ll see. In any case, wherever you are, stay safe, happy holidays, and see you on the line next year.

Random Short Take #47

Welcome to Random Short Take #47. Not a great many players have worn 47 in the NBA, but Andrei “AK-47” Kirilenko did. So let’s get random.

  • I’ve been doing some stuff with Runecast in my day job, so this post over at Gestalt IT really resonated.
  • I enjoyed this article from Alastair on AWS Design, and the mention of “handcrafted perfection” in particular has put an abrupt end to any yearning I’d be doing to head back into the enterprise fray.
  • Speaking of AWS, you can now hire Mac mini instances. Frederic did a great job of documenting the process here.
  • Liking VMware Cloud Foundation but wondering if you can get it via your favourite public cloud provider? Wonder no more with this handy reference from Simon Long.
  • Ransomware. Seems like everyone’s doing it. This was a great article on the benefits of the air gap approach to data protection. Remember, it’s not a matter of if, but when.
  • Speaking of data protection and security, BackupAssist Classic v11 launched recently. You can read the press release here.
  • Using draw.io but want to use some VVD stencils? Christian has the scoop here.
  • Speaking of VMware Cloud Director, Steve O has a handy guide on upgrading to 10.2 that you can read here.

Random Short Take #31

Welcome to Random Short Take #31. Lot of good players have worn 31 in the NBA. You’d think I’d call this the Reggie edition (and I appreciate him more after watching Winning Time), but this one belongs to Brent Barry. This may be related to some recency bias I have, based on the fact that Brent is a commentator in NBA 2K19, but I digress …

  • Late last year I wrote about Scale Computing’s big bet on a small form factor. Scale Computing recently announced that Jerry’s Foods is using the HE150 solution for in-store computing.
  • I find Plex to be a pretty rock solid application experience, and most of the problems I’ve had with it have been client-related. I recently had a problem with a server update that borked my installation though, and had to roll back. Here’s the quick and dirty way to do that on macOS.
  • Here’s are 7 contentious thoughts on data protection from Preston. I think there are some great ideas here and I recommend taking the time to read this article.
  • I recently had the chance to speak with Michael Jack from Datadobi about the company’s announcement about its new DIY Starter Pack for NAS migrations. Whilst it seems that the professional services market for NAS migrations has diminished over the last few years, there’s still plenty of data out there that needs to be moved from on box to another. Robocopy and rsync aren’t always the best option when you need to move this much data around.
  • There are a bunch of things that people need to learn to do operations well. A lot of them are learnt the hard way. This is a great list from Jan Schaumann.
  • Analyst firms are sometimes misunderstood. My friend Enrico Signoretti has been working at GigaOm for a little while now, and I really enjoyed this article on the thinking behind the GigaOm Radar.
  • Nexsan recently announced some enhancements to its “BEAST” storage platforms. You can read more on that here.
  • Alastair isn’t just a great writer and moustache aficionado, he’s also a trainer across a number of IT disciplines, including AWS. He recently posted this useful article on what AWS newcomers can expect when it comes to managing EC2 instances.

Random Short Take #20

Posted on by

Here are some links to some random news items and other content that I recently found interesting. You might find them interesting too. Episode 20 – feels like it’s becoming a thing.

  • Scale Computing seems to be having a fair bit of success with their VDI solutions. Here’s a press release about what they did with Harlingen WaterWorks System.
  • I don’t read Corey Quinn’s articles enough, but I am glad I read this one. Regardless of what you think about the enforceability of non-compete agreements (and regardless of where you’re employed), these things have no place in the modern workforce.
  • If you’re getting along to VMworld US this year, I imagine there’s plenty in your schedule already. If you have the time – I recommend getting around to seeing what Cody and Pure Storage are up to. I find Cody to be a great presenter, and Pure have been doing some neat stuff lately.
  • Speaking of VMworld, this article from Tom about packing the little things for conferences in preparation for any eventuality was useful. And if you’re heading to VMworld, be sure to swing past the VMUG booth. There’s a bunch of VMUG stuff happening at VMworld – you can read more about that here.
  • I promise this is pretty much the last bit of news I’ll share regarding VMworld. Anthony from Veeam put up a post about their competition to win a pass to VMworld. If you’re on the fence about going, check it out now (as the competition closes on the 19th August).
  • It wouldn’t be a random short take without some mention of data protection. This article about tiering protection data from George Crump was bang on the money.
  • Backblaze published their quarterly roundup of hard drive stats – you can read more here.
  • This article from Paul on freelancing and side gigs was comprehensive and enlightening. If you’re thinking of taking on some extra work in the hopes of making it your full-time job, or just wanting to earn a little more pin money, it’s worthwhile reading this post.

Here are a few links to some random news items and other content that I found interesting. You might find it interesting too. Maybe. This will be the last one for this year. I hope you and yours have a safe and merry Christmas / holiday break.

  • Scale Computing have finally entered the Aussie market in partnership with Amnesium. You can read more about that here. 
  • Alastair is back in the classroom, teaching folks about AWS. He published a bunch of very useful notes from a recent class here.
  • The folks at Backblaze are running a “Refer-A-Friend” promotion. If you’re looking to become a new Backblaze customer and sign up with my referral code, you’ll get some free time on your account. And I will too! Hooray! I’ve waxed lyrical about Backblaze before, and I recommend it. The offer runs out on January 6th 2019, so get a move on.
  • Howard did a nice article on VVols that I recommend checking out.
  • GDPR has been a challenge (within and outside the EU), but I enjoyed Mark Browne‘s take on Cohesity’s GDPR compliance.
  • I’m quite a fan of the Netflix Tech Blog, and this article on the Netflix Media Database was a ripper.
  • From time to time I like to poke fun at my friends in the US for what seems like an excessive amount of shenanigans happening in that country, but there’s plenty of boneheaded stuff happening in Australia too. Read Preston’s article on the recently passed anti-encryption laws to get a feel for the heady heights of stupidity that we’ve been able to reach recently.

 

Nexenta Announces NexentaCloud

Posted on by

I haven’t spoken to Nexenta in some time, but that doesn’t mean they haven’t been busy. They recently announced NexentaCloud in AWS, and I had the opportunity to speak to Michael Letschin about the announcement.

 

What Is It?

In short, it’s a version of NexentaStor that you can run in the cloud. It’s ostensibly an EC2 machine running in your virtual private cloud using EBS for storage on the backend. It’s:

  • Available in the AWS Marketplace;
  • Is deployed on preconfigured Amazon Machine Images; and
  • Delivers unified file and block services (NFS, SMB, iSCSI).

According to Nexenta, the key benefits include:

  • Access to a fully-featured file (NFS and SMB) and block (iSCSI) storage array;
  • Improved cloud resource efficiency through
    • data reduction
    • thin provisioning
    • snapshots and clones
  • Seamless replication to/from NexentaStor and NexentaCloud;
  • Rapid deployment of NexentaCloud instances for test/dev operations;
  • Centralised management of NexentaStor and NexentaCloud;
  • Advanced Analytics across your entire Nexenta storage environment; and
  • Migrate legacy applications to the cloud without re-architecting your applications.

There’s an hourly or annual subscription model, and I believe there’s also capacity-based licensing options available.

 

But Why?

Some of the young people reading this blog who wear jeans to work every day probably wonder why on earth you’d want to deploy a virtual storage array in your VPC in the first place. Why would your cloud-native applications care about iSCSI access? It’s very likely they don’t. But one of the key reasons why you might consider the NexentaCloud offering is because you’ve not got the time or resources to re-factor your applications and you’ve simply lifted and shifted a bunch of your enterprise applications into the cloud. These are likely applications that depend on infrastructure-level resiliency rather than delivering their own application-level resiliency. In this case, a product like NexentaCloud makes sense in that it provides some of the data services and resiliency that are otherwise lacking with those enterprise applications.

 

Thoughts

I’m intrigued by the NexentaCloud offering (and by Nexenta the company, for that matter). They have a solid history of delivering interesting software-defined storage solutions at a reasonable cost and with decent scale. If you’ve had the chance to play with NexentaStor (or deployed it in production), you’ll know it’s a fairly solid offering with a lot of the features you’d look for in a traditional storage platform. I’m curious to see how many enterprises take advantage of the NexentaCloud product, although I know there are plenty of NexentaStor users out in the wild, and I have no doubt their CxOs are placing a great amount of pressure on them to don the cape and get “to the cloud” post haste.
