Welcome to Random Short Take #81. Last one for the year, because who really wants to read this stuff over the holiday season? Let’s get random.
Curtis did a podcast on archive and retrieve as part of his “Backup to Basics” series. It’s something I feel pretty strongly about, so much so that I wrote a chapter in his book about it. You can listen to it here.
More William Gibson content is coming to our screens, with the announcement that Neuromancer is coming to Apple TV. I hope it’s as well done as The Peripheral. Hat tip to John Birmingham for posting the news on his blog.
It’s been a while since I looked at Dell storage, but my friend Max wrote a great article over at Gestalt IT on Dell PowerStore.
I love Backblaze. Not in the sense that I want to marry the company, but I really like what the folks there do. And I really like the transparency with which they operate. This article giving a behind the scenes look at its US East Data Center is a fantastic example of that.
And, to “celebrate” 81 Random Short Takes (remember when I used to list my favourite NBA players and the numbers they wore?), let’s take a stroll down memory lane with two of my all-time, top 5, favourite NBA players – Kobe Bryant and Jalen Rose. The background for this video is explained by Jalen here.
Take care of yourselves and each other, and I’ll hopefully see you all on the line or in person next year.
It’s been a while since I’ve looked at Dell Technologies closely, but Tech Field Day recently ran an event and Pietro put together a pretty comprehensive view of what was covered.
Dr Bruce Davie is a smart guy, and this article over at El Reg on decentralising Internet services made for some interesting reading.
Clean installs and Time Machine system recoveries on macOS aren’t as nice as they used to be. I found this out a day or two before this article was published. It’s worth reading nonetheless, particularly if you want to get your head around the various limitations with Recovery Mode on more modern Apple machines.
If you follow me on Instagram, you’ll likely realise I listen to records a lot. I don’t do it because they “sound better” though, I do it because it works for me as a more active listening experience. There are plenty of clowns on the Internet ready to tell you that it’s a “warmer” sound. They’re wrong. I’m not saying you should fight them, but if you find yourself in an argument this article should help.
Speaking of technologies that have somewhat come and gone (relax – I’m joking!), this article from Chris M. Evans on HCI made for some interesting reading. I always liked the “start small” approach with HCI, particularly when comparing it to larger midrange storage systems. But things have definitely changed when it comes to available storage and converged options.
Welcome to Random Short Take #43. A few players have worn 43 in the NBA, including Frank Brickowski, but my favourite from this list is Red Kerr (more for his commentary chops than his game, I think). Let’s get random.
Mike Wilson has published Part 2 of his VMware VCP 2020 Study Guide and it’s a ripper. Check it out here. I try to duck and weave when it comes to certification exams nowadays, but these kind of resources are invaluable.
It’s been a while since I had stick time with Data Domain OS, but Preston’s article on password hardening was very useful.
Mr Foskett bought a cloud, of sorts. Read more about that here. Anyone who knows Stephen knows that he’s all about what’s happening in the industry, but I do enjoy reading about these home projects as well.
Speaking of clouds, Rancher was named “A Leader” in multi-cloud container development platforms by an independent research firm. You can read the press release here.
Datadobi had a good story to share about what it did with UMass Memorial Health Care. You can read the story here.
Steve O has done way too much work understanding how to change the default theme in Veeam Enterprise Manager 10 and documenting the process so you don’t need to work it out. Read about the process here.
Welcome to Random Short Take #37. Not a huge amount of players have worn 37 in the NBA, but Metta World Peace did a few times. When he wasn’t wearing 15, and other odd numbers. But I digress. Let’s get random.
Pavilion Data recently added S3 capability to its platform. It’s based on a variant of MinIO, and adds an interesting dimension to what Pavilion Data has traditionally offered. Mellor provided some good coverage here.
Speaking of object storage, Dell EMC recently announced ECS 3.5. You can read more on that here. The architectural white paper has been updated to reflect the new version as well.
Online events are all the rage at the moment, and two noteworthy events are coming up shortly: Pure//Accelerate and VeeamON 2020. Speaking of online events, we’re running a virtual BNEVMUG next week. Details on that here. ZertoCON Virtual is also a thing.
Speaking of Pure Storage, this article from Cody Hosterman on NVMe and vSphere 7 is lengthy, but definitely worth the read.
I can’t recall whether I mentioned that this white paper covering VCD on VCF 3.9 is available now, and I can’t be bothered checking. So here it is.
I’m not just a fan of Backblaze because of its cool consumer backup solution and object storage platform, I’m also a big fan because of its blog. Articles like this one are a great example of companies doing corporate culture right (at least from what I can see).
I have the impression that Datadobi has been doing some cool stuff recently, and this story certainly seems to back it up.
Welcome to Random Short Take #36. Not a huge amount of players have worn 36 in the NBA, but Shaq did (at the end of his career), and Marcus Smart does. This one, though, goes out to one of my favourite players from the modern era, Rasheed Wallace. It seems like Boston is the common thread here. Might have something to do with those hall of fame players wearing numbers in the low 30s. Or it might be entirely unrelated.
Scale Computing recently announced its all-NVMe HC3250DF as a new appliance targeting core data centre and edge computing use cases. It offers higher performance storage, networking and processing. You can read the press release here.
Dell EMC PowerStore has been announced. Chris Mellor covered the announcement here. I haven’t had time to dig into this yet, but I’m keen to learn more. Chris Evans also wrote about it here.
StorCentric’s Nexsan recently announced the E-Series 32F Storage Platform. You can read the press release here.
In what can only be considered excellent news, Preston de Guisehas announced the availability of the second edition of his book, “Data Protection: Ensuring Data Availability”. It will be available in a variety of formats, with the ebook format already being out. I bought the first edition a few times to give as a gift, and I’m looking forward to giving away a few copies of this one too.
Backblaze B2 has been huge for the company, and Backblaze B2 with S3-compatible API access is even huger. Read more about that here. Speaking of Backblaze, it just released its hard dive stats for Q1, 2020. You can read more on that here.
Hal recently upgraded his NUC-based home lab to vSphere 7. You can read more about the process here.
Jon recently posted an article on a new upgrade command available in OneFS. If you’re into Isilon, you might just be into this.

The data centre is changing, as is the way we manage it. There’s been an observable evolution of the applications we run in the DC and a need for better tools. The traditional approach to managing infrastructure, with siloed teams of storage, network, and compute administrators, is also becoming less common. One of the key parts of this story is the growing need for automation. As operational organisations in charge of infrastructure and applications, we want to:
Manage large scale operations across the hybrid cloud;
Enable DevOps and CI/CD models with infrastructure as code (operational discipline); and
Deliver self service experience.
Automation has certainly gotten easier, and as an industry we’re moving from brute force scripting to assembling pre-built modules.

Dell EMC and vRO for storage
VMware’s vRealize Orchestrator has been around for some time. It has a terrible name, but does deliver on its promise of simple automation for VMware environments.
Plugins allow full automation, from storage to VM
Easily integrated with other automation tools
The cool thing about the plugin is that you can replace homegrown scripts with a pre-written set of plugins fully supported by Dell EMC.
You can also use vRO to implement automated policy based workflows:
Automatic extension of datastores;
Configure storage the same way every time; and
Tracking of operations in a single place.
vRO plugs in to vRealize Automation as well, giving you self service catalogue capabilities along with support for quotas and roles.
What does the vRO plugin support?
Supported Arrays
PowerMax / VMAX All-Flash (Enterprise)
Unity (Midrange)
XtremIO
Storage Provisioning Operations
Adds
Moves
Changes
Array Level Data Protection Services
Snapshots
Remote replication
Thoughts and Further Reading
DevOps means a lot of things to a lot of people. Which is a bit weird, because some smart folks have written a handbook that lays it all out for us to understand. But the point is that automation is a big part of what makes DevOps work at a functional level. The key to a successful automation plan, though, is that you need to understand what you want to automate, and why you want to automate it. There’s no point automating every process in your organisation if you don’t understand why you do that process in the first place.
Does the presence of a vRO plugin mean that Dell EMC will make it super easy for you to automate daily operations in your storage environment? Potentially. As long as you understand the need for those operations and they’re serving a function in your organisation. I’m waffling, I know, but the point I’m attempting to make is that having a tool bag / shed / whatever is great, and automating daily processes is great, but the most successful operations environments are mature enough to understand not just the how but the why. Taking what you do every day and automating it can be a terrifically time-consuming activity. The important thing to understand is why you do that activity in the first place.
I’m really pleased that Dell EMC has made this level of functionality available to end users of its storage platforms. Storage administration and operations can still be a complicated endeavour, regardless of whether you’re a storage administrator comfortably ensconced in an operational silo, or one of those cool site reliability engineers wearing jeans to work every day and looking after thousands of cloud-native apps. I don’t think it’s the final version of what these tools look like, or what Dell EMC want to deliver in terms of functionality, but it’s definitely a step in the right direction.

One of the key features of the Isilon platform has been its scalability. OneFS automatically expands the filesystem across additional nodes. This scalability is impressive, and the platform has the ability to linearly scale both capacity and performance. It supports up to 252 nodes, petabytes of capacity and millions of file operations. My favourite thing about the scalability story, though, is that it’s non-disruptive. Dell EMC says it takes less than 60 seconds to add a node. That assumes you’ve done a bit of pre-work, but it’s a good story to tell. Even better, Isilon supports automated workload rebalancing – so your data is automatically redistributed to take advantage of new nodes when they’re added.
One Filesystem
They call it OneFS for a reason. Clients can read / write from any Isilon node, and client connections are distributed across cluster. Each file is automatically distributed across the cluster. This means that the larger the cluster, the better the efficiency and performance is. OneFS is also natively multi-protocol – clients can read / write same data over multiple protocols.
Always-on
There are some neat features in terms of resiliency too.
The cluster can sustain multiple failures with no impact – no impact for failures of up to 4 nodes or 4 drives in each pool
Non-disruptive tech refresh – non-disruptively add, remove or replace nodes in the cluster
No dedicated spare nodes or drives – better efficiency as no node or drive is unused
There is support for an ultra dense configuration: 4 nodes in 4U, offering up to 240TB raw per RU.

Isilon in the Cloud
All this Isilon stuff is good, but what if you want to leverage those features in a more cloud-friendly way? Dell EMC has you covered. There’s a good story with getting data to and from the major public cloud providers (in a limited amount of regions), and there’s also an interesting solution when it comes to running OneFS in the cloud itself.

Thoughts and Further Reading
If you’re familiar with Isilon, a lot of what I’ve covered here wouldn’t be news, and would likely be a big part of the reason why you might even be an existing customer. But the OneFS in the public cloud stuff may come as a bit of a surprise. Why would you do it? Why would you pay over the odds to run appliance-like storage services when you could leverage native storage services from these cloud providers? Because the big public cloud providers expect you to have it all together, and run applications that can leverage existing public cloud concepts of availability and resiliency. Unfortunately, that isn’t always the case, and many enterprises find themselves lifting and shifting workloads to public clouds. OneFS gives those customers access to features that may not be available to them using the platform natively. These kinds of solutions can also be interesting in the verticals where Isilon has traditionally proven popular. Media and entertainment workloads, for example, often still rely on particular tools and workflows that aren’t necessarily optimised for public cloud. You might have a render job that you need to get done quickly, and the amount of compute available in the public cloud would make that a snap. So you need storage that integrates nicely with your render workflow. Suddenly these OneFS in X Cloud services are beginning to make sense.
It’s been interesting to watch the evolution of the traditional disk slingers in the last 5 years. I don’t think the public cloud has eaten their lunch by any means, but enterprises continue to change the way they approach the need for core infrastructure services, across all of the verticals. Isilon continues to do what it did in the first place – scale out NAS – very well. But Dell EMC has also realised that it needs to augment its approach in order to keep up with what the hyperscalers are up to. I don’t see on-premises Isilon going away any time soon, but I’m also keen to see how the product portfolio develops over the next few years. You can read some more on OneFS in Google Cloud here.
Welcome to my semi-regular, random news post in a short format. This is #26. I was going to start naming them after my favourite basketball players. This one could be the Korver edition, for example. I don’t think that’ll last though. We’ll see. I’ll stop rambling now.
Do you know Cody? Cody’s a smart guy, and very good at expressing technical things on his blog. This article on deploying the Pure Storage OVA using PowerShell is a good example of that.
InfiniteIO has been doing some cool stuff. I spoke to them recently and will be writing something about them in the near future. In the meantime, here’s their most recent press release.
I wrote about Excelero recently, but neglected to mention some of what it’s been doing with NVIDIA. You can read more about that here.
Want some news? In a shorter format? And a little bit random? This listicle might be for you. Welcome to #24 – The Kobe Edition (not a lot of passing, but still entertaining). 8 articles too. Which one was your favourite Kobe? 8 or 24?
I wrote an article about how architecture matters years ago. It’s nothing to do with this one from Preston, but he makes some great points about the importance of architecture when looking to protect your public cloud workloads.
Commvault GO 2019 was held recently, and Chin-Fah had some thoughts on where Commvault’s at. You can read all about that here. Speaking of Commvault, Keith had some thoughts as well, and you can check them out here.
Still on data protection, Alastair posted this article a little while ago about using the Cohesity API for reporting.
VMware vFORUM is coming up in November. I’ll be making the trip down to Sydney to help out with some VMUG stuff. You can find out more here, and register here.
Speaking of VMUG, Angelo put together a great 7-part series on VMUG chapter leadership and tips for running successful meetings. You can read part 7 here.
The August edition of the Brisbane VMUG meeting will be held on Tuesday 20th August at Fishburners from 4 – 6pm. It’s sponsored by Dell EMC and should to be a great afternoon.
Here’s the agenda:
VMUG Intro
VMware Presentation: TBA
Dell EMC Presentation: Protecting Your Critical Assets With Dell EMC
Q&A
Refreshments and drinks.
Dell EMC have gone to great lengths to make sure this will be a fun and informative session and I’m really looking forward to hearing about their data protection portfolio. You can find out more information and register for the event here. I hope to see you there. Also, if you’re interested in sponsoring one of these events, please get in touch with me and I can help make it happen.
