StorCentric Announces Nexsan Unity NV10000

Posted on by

Nexsan (a StorCentric company) recently announced the Nexsan Unity NV10000. I thought I’d share a few of my thoughts here.

What Is It? 
In the immortal words of Silicon Valley: “It’s a box“. But the Nexsan Unity NV10000 is a box with some fairly decent specifications packed in a small form-factor, including support for various 1DWPD NVMe SSDs and the latest Intel Xeon processors.
Protocol Support
Protocol support, as would be expected with the Unity, is broad, with support for File (NFS, SMB), Block (iSCSI, FC), and Object (S3) data storage protocols within the one unified platform.
Performance Enhancements
These were hinted at with the release of Unity 7.0, but the Nexsan Unity NV10000 boosts performance by increasing bandwidths of up to 25GB/s, enabling you to scale performance up as your application needs evolve.

Other Useful Features

As you’d expect from this kind of storage array, the Nexsan Unity NV10000 also delivers features such as:

  • High availability (HA);
  • Snapshots;
  • ESXi integration;
  • In-line compression;
  • FASTier™ caching;
  • Asynchronous replication;
  • Data at rest encryption; and
  • Storage pool scrubbing to protect against bit rot, avoiding silent data corruption.

Backup Target?

Unity supports a comprehensive Host OS matrix and is certified as a Veeam Ready Repository for backups. Interestingly, the Nexsan Unity NV10000 also provides data security, regulations compliance, and ransomware recoverability. The platform also supports immutable block and file and S3 object locking, for data backup that is unchangeable and cannot be encrypted, even by internal bad actors.

Thoughts

I’m not as much of a diskslinger as I used to be, but I’m always interested to hear about what StorCentric / Nexsan has been up to with its storage array releases. It strikes me that the company does well by focussing on those features that customers are looking for (fast storage, peace of mind, multiple protocols) and also by being able to put it in a form-factor that appeals in terms of storage density. While the ecosystem around StorCentric is extensive, it makes sense for the most part, with the various components coming together well to form a decent story. I like that the company has really focussed on ensuring that Unity isn’t just a cool product name, but also a key part of the operating environment that powers the solution.

StorCentric Announces Nexsan Unity 7.0

Posted on by

Nexsan (a StorCentric company) recently announced version 7.0 of its Unity software platform. I had the opportunity to speak to StorCentric CTO Surya Varanasi about the announcement and thought I’d share a few of my thoughts here.

 

What’s New?

In short, there’s a fair bit that’s gone into this release, and I’ll cover these below.

Protocol Enhancements

The Unity platform already supported FC, iSCSI, NFS, and SMB. It now supports S3 as well, making interoperability with data protection software that supports S3 as a target even simpler. It also means you can do stuff with Object Locking, and I’ll cover that below.

There have also been some enhancements to the speeds supported on the Unity hardware interfaces, and FC now supports up to 32Gbps, and support for 1/10/25/40/100GbE over Ethernet.

Security, Compliance and Ransomware Protection

Unity now supports immutable volume and file system snapshots for data protection. This provides secure point-in-time copies of data for business continuity.  As I mentioned before, there’s also support for object locking, enabling bucket or object-level protection for a specified retention period to create immutable copies of data. This allows enterprises to address compliance, regulatory and other data protection requirements. Finally, there’s now support for pool-scrubbing to detect and remediate bit rot to avoid data corruption.

Performance Improvements

There have been increases in total throughput capability, with Varanasi telling me that Total Throughput has increased up to 13GB/s on existing platforms. There’s also been a significant improvement in the Unity to Assureon ingestion rate. I’ve written a little about the Unbreakable Backup solution before, and there’s a lot to like about the architecture.

Thoughts

This is the first time that Nexsan has announced enhancements to its Unity platform without incorporating some kind of hardware refresh, so the company is testing the waters in some respects. I think it’s great when storage companies are able to upgrade their existing hardware platforms with software and offering improved performance and functionality. There’s a lot to like in this release, particularly when it comes to the improved security and data integrity capabilities. Sure, not everyone wants object storage available on their midrange storage array, but it makes it a lot more accessible, particularly if you only need a few 100TB of object. The object lock capability, along with the immutable snapshotting for SMB and NFS users, really helps improve the overall integrity and resiliency of the platform as well.

StorCentric now has a pretty broad portfolio of storage and data protection products available, and you can see the integrations between the different lines are only going to increase as time goes on. The company has been positioning itself as a data-centric company for some time, and working hard to ensure that improved security is a big part of that solution. I think there’s a great story here for customers looking to leverage one vendor to deliver storage, data protection, and data security capabilities into the enterprise. The bad guys in hoodies are always looking for ways to make your day unpleasant, so when vendors are working to tighten up their integrations across a variety of products, it can only be a good thing in terms of improving the resilience and availability of your critical information assets. I’m looking forward to hearing what’s next with Nexsan and StorCentric.

Random Short Take #51

Welcome to Random Short Take #51. A few players have worn 51 in the NBA including Lawrence Funderburke (I remember the Ohio State team wearing grey Nikes on TV and thinking that was a really cool sneaker colour – something I haven’t been able to shake over 25 years later). My pick is Boban Marjanović though. Let’s get random.

  • Folks don’t seem to spend much time making sure the fundamentals are sound, particularly when it comes to security. This article from Jess provides a handy list of things you should be thinking about, and doing, when it comes to securing your information systems. As she points out, it’s just a starting point, but I think it should be seen as a bare minimum / entry level set of requirements that you could wrap around most environments out in the wild.
  • Could there be a new version of AIX on the horizon? Do I care? Not really. But I do sometimes yearn for the “simpler” times I spent working on a myriad of proprietary open systems, particularly when it came to storage array support.
  • StorCentric recently announced Nexsan Assureon Cloud Edition. You can read the press release here.
  • Speaking of press releases, Zerto continues to grow its portfolio of cloud protection technology. You can read more on that here.
  • Spectro Cloud has been busy recently, and announced supporting for management of existing Kubernetes deployments. The news on that can be found here.
  • Are you a data hoarder? I am. This article won’t help you quit data, but it will help you understand some of the things you can do to protect your data.
  • So you’ve found yourself with a publicly facing vCenter? Check out this VMware security advisory, and get patching ASAP. vCenter is the only thing you need to be patching either, but hopefully you knew that already.

StorCentric Announces Nexsan Unity 3300 And 7900

Posted on by

StorCentric recently announced new Nexsan Unity storage arrays. I had the opportunity to speak to Surya Varanasi, CTO of StorCentric, about the announcement, and thought I’d share some thoughts here.

 

Speeds And Feeds

[image courtesy of Nexsan]

The new Unity models announced are the 3300 and 7900. Both models use two controllers and vary in capacity between 1.6PB and 6.7PB. They both use the Intel Xeon E5 v4 Family processors, and have between 256GB and 448GB of system RAM. There are hybrid storage options available, and both systems support RAID 5, 6, and 10. You can access the spec sheet here.

 

Use Cases

Unbreakable

One of the more interesting use cases we discussed was what StorCentric refer to as “Unbreakable Backup”. The idea behind Nexsan Unbreakable Backup is that you can use your preferred data protection vendor to send backup data to a Unity array. This data can then be replicated to Nexsan’s Assureon platform. The cool thing about the Assureon is that it’s a locked down solution. So even if you’re hit with a ransomware attack, it’s going to be mighty hard for the bad guys to crack the Assureon platform as well, as StorCentric uses a Key Management System hosted inside StorCentric, and provides minimal privileges to end users.

Data Migration

There’s also a Data Mobility Suite coming at the end of Q3, including:

  • Cloud Connector, giving you the ability to replicate data from Unity to 18 Public clouds including Amazon and Google (for unstructured data, cloud-based backup); and
  • Flexible Data Migrations – streamline Unity implementations, migrate data from heterogeneous systems.

 

Thoughts and Further Reading

I’ve written enthusiastically about Assureon in the past, so it was nice to revisit the platform via this announcement. Ransomware is a scary prospect for many organisations, so a system that can integrate nicely to help with protecting protection data seems like a pretty good idea. Sure, having to replicate the data to a second system might seem like an unnecessary expense, but organisations should be assessing the value of that investment against the cost of having corporate data potentially irretrievably corrupted. Insurance against ransomware attacks probably seems like something that you shouldn’t need to spend money on, until you need to spend money recovering, or sending bitcoin to some clown because you need your data back. It’s not appealing by any stretch, but it’s also important to take precautions wherever possible.

Midrange storage is by no means a sexy topic to talk about. In my opinion it’s a well understood architecture that most tier 1 companies do pretty well nowadays. But that’s the beauty of the midrange system in a lot of ways – it’s a well understood architecture. So you generally know what you’re getting with hybrid (or all-flash) dual controller systems. The Unity range from Nexsan is no different, and that’s not a bad thing. There are a tonne of workloads in the enterprise today that aren’t necessarily well suited to cloud (for the moment), and just need some block or file storage and a bit of resiliency for good measure. The Unity series of arrays from Nexsan offer a bunch of useful features, including tiering and a variety of connectivity options. It strikes me that these arrays are a good fit for a whole lot of workloads that live in the data centre, from enterprise application hosting through to data protection workloads. If you’re after a reliable workhorse, it’s worth looking into the Unity range.

Random Short Take #36

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.

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 …

  • 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.

StorCentric Announces QLC E-Series 18F

Posted on by

Nexsan recently announced the release of its new E-Series 18F (E18F) storage platform. I had the chance to chat with Surya Varanasi, CTO of StorCentric, about the announcement and thought I’d share some thoughts here.

 

Less Disk, More Flash

[image courtesy of Nexsan]

The E18F is designed and optimised for quad-level cell (QLC) NAND technology. If you’re familiar with the Nexsan E-Series range, you’d be aware of the E18P that preceded this model. This is the QLC Flash version of that.

Use Cases

We spoke about a couple of use cases for the E18F. The first of these was with data lake environments. These are the sort of storage environents with 20 to 30PB installations that are subjected to random workload pressures. The idea of using QLC is to increase the performance without significantly increasing the cost. That doesn’t mean that you can do a like for like swap of HDDs for QLC Flash. Varanasi did, however, suggest that Nexsan had observed a 15x improvement over hard drive installation for around 3-4 times the cost, and he’s expecting that to go down to 2-3 times in the future. There is also the option to use just a bit of QLC Flash with a lot of HDDs to get some performance improvement.

The other use case discussed was the use of QLC in test and dev environments. Users are quite keen, obviously, on getting Flash in their environments at the price of HDDs. This isn’t yet a realistic goal, but it’s more achievable with QLC than it is with something like TLC.

 

QLC And The Future

We spoke briefly about more widespread adoption of QLC across the range of StorCentric storage products. Varanasi said the use “will eventually expand across the portfolio”, and they were looking at how it might be adopted with the larger E-Series models, as well as with the Assureon and Vexata range. They were treating Unity more cautiously, as the workloads traditionally hosted on that platform were a little more demanding.

 

Thoughts and Further Reading

The kind of workloads we’re throwing at what were once viewed as “cheap and deep” platforms is slowly changing. Where once it was perhaps acceptable to wait a few days for reporting runs to finish, there’s no room for that kind of performance gap now. So it makes sense that we look to Flash as a way of increasing the performance of the tools we’re using. The problem, however, is that when you work on data sets in the petabyte range, you need a lot of capacity to accommodate that. Flash is getting cheaper, but it’s still not there when compared to traditional spinning disks. QLC is a nice compromise between performance and capacity. There’s a definite performance boost to be had, and the increase in cost isn’t eye watering. StorCentric Announces QLC E-Series 18F

I’m interested to see how this solution performs in the real world, and whether QLC has the expected durability to cope with the workloads that enterprise will throw at it. I’m also looking forward to seeing where else Nexsan decide to use QLC in its portfolio. There’s good story here in terms of density, performance, and energy consumption – one that I’m sure other vendors will also be keen to leverage. For another take on this, check out Mellor’s article here.

Nexsan Announces Assureon Cloud Transfer

Posted on by

Announcement

Nexsan announced Cloud Transfer for their Assureon product a little while ago. I recently had the chance to catch up with Gary Watson (Founder / CTO at Nexsan) and thought it would be worth covering the announcement here.

 

Assureon Refresher

Firstly, though, it might be helpful to look at what Assureon actually is. In short, it’s an on-premises storage archive that offers:

  • Long term archive storage for fixed content files;
  • Dependable file availability, with files being audited every 90 days;
  • Unparalleled file integrity; and
  • A “policy” system for protecting and stubbing files.

Notably, there is always a primary archive and a DR archive included in the price. No half-arsing it here – which is something that really appeals to me. Assureon also doesn’t have a “delete” key as such – files are only removed based on defined Retention Rules. This is great, assuming you set up your policies sensibly in the first place.

 

Assureon Cloud Transfer

Cloud Transfer provides the ability to move data between on-premises and cloud instances. The idea is that it will:

  • Provide reliable and efficient cloud mobility of archived data between cloud server instances and between cloud vendors; and
  • Optimise cloud storage and backup costs by offloading cold data to on-premises archive.

It’s being positioned as useful for clients who have a large unstructured data footprint on public cloud infrastructure and are looking to reduce their costs for storing data up there. There’s currently support for Amazon AWS and Microsoft Azure, with Google support coming in the near future.

There’s stub support for those applications that support. There’s also an optional NFS / SMB interface that can be configured in the cloud as an Assureon archiving target that caches hot files and stubs cold files. This is useful for those non-Windows applications that have a lot of unstructured data that could be moved to an archive.

 

Thoughts and Further Reading

The concept of dedicated archiving hardware and software bundles, particularly ones that live on-premises, might seem a little odd to some folks who spend a lot of time failing fast in the cloud. There are plenty of enterprises, however, that would benefit from the level of rigour that Nexsan have wrapped around the Assureon product. It’s my strong opinion that too many people still don’t understand the difference between backup and recovery and archive data. The idea that you need to take archive data and make it immutable (and available) for a long time has great appeal, particularly for organisations getting slammed with a whole lot of compliance legislation. Vendors have been talking about reducing primary storage use for years, but there seems to have been some pushback from companies not wanting to invest in these solutions. It’s possible that this was also a result of some kludgy implementations that struggled to keep up with the demands of the users. I can’t speak for the performance of the Assureon product, but I like the fact that it’s sold as a pair, and with a lot of the decision-making around protection taken away from the end user. As someone who worked in an organisation that liked to cut corners on this type of thing, it’s nice to see that.

But why would you want to store stuff on-premises? Isn’t everyone moving everything to the cloud? No, they’re not. I don’t imagine that this type of product is being pitched at people running entirely in public cloud. It’s more likely that, if you’re looking at this type of solution, you’re probably running a hybrid setup, and still have a footprint in a colocation facility somewhere. The benefit of this is that you can retain control over where your archived data is placed. Some would say that’s a bit of a pain, and an unnecessary expense, but people familiar with compliance will understand that business is all about a whole lot of wasted expense in order to make people feel good. But I digress. Like most on-premises solutions, the Assureon offering compares well with a public cloud solution on a $/GB basis, assuming you’ve got a lot of sunk costs in place already with your data centre presence.

The immutability story is also a pretty good one when you start to think about organisations that have been hit by ransomware in the last few years. That stuff might roll through your organisation like a hot knife through butter, but it won’t be able to do anything with your archive data – that stuff isn’t going anywhere. Combine that with one of those fancy next generation data protection solutions and you’re in reasonable shape.

In any case, I like what the Assureon product offers, and am looking forward to seeing Nexsan move beyond the Windows-only platform support that it currently offers. You can read the Nexsan Assueron Cloud Transfer press release here. David Marshall covered the announcement over at VMblog and ComputerWeekly.com did an article as well.

Nexsan Announces Unity 2.0

Posted on by

Nexsan announced their new range of Unity arrays a few weeks ago. I finally had the opportunity to talk to Gary Watson about the new line, and thought it was worth covering here.

 

Hardware

The Unity range of arrays are standard midrange offerings. They use two controllers and offer some useful block and file access options. Capacity is pretty good too. My favourite feature (based on past experience) is the data mobility, thanks to the Connected Data acquisition. I was a big fan of the consumer version of the Transporter, and think that delivering these kind of features in a corporate environment is a great way to get around the problem of widespread Dropbox use in the enterprise. (Not that I’m not a fan of Dropbox, but people need to be mindful of what they do with corporate data in the name of “convenience”.) Here’s a snazzy box shot.

And here’s a table that nicely summarises the various Unity offerings. You can grab the data sheet from here and a more detailed specification sheet here.

Further Reading and Conclusion

You can read some press coverage on the announcement here and here. Nexsan’s press release can also be found here. Dell EMC don’t like talking about it, but you’ve probably noticed two different companies are using Unity as a product name for their midrange storage line. You can read El Reg’s coverage of that here.

The Unity arrays do everything you’d expect a modern midrange array to do, with the added bonus of some neat enterprise file sharing capability thrown in for good measure. In the storage industry we love to focus on what we think people will find sexy. Right now this seems to be two things: all flash storage and massively scalable object storage. Don’t get me wrong, both of those technology solutions are neat, and it’s certainly an exciting time to be witnessing what can be done with that technology. That said, I don’t think the midrange storage array is dead just yet. There are plenty of companies in the hunt for storage platforms that just work and deliver reasonable performance for a decent price per GB. As evidenced by Dell EMC’s continued interest and investment in the midrange market, there’s still plenty of life left in it. If you’re in the market for some solid midrange storage with a variety of storage options and capacities, coupled with some neat file synchronisation and replication technology, then it’s worth looking into the Nexsan offering.
