Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
8.5
Pure Storage FlashBlade boosts ROI by reducing costs, enhancing efficiencies, increasing VM density, and saving 20%-85% in time.
Sentiment score
7.0
PowerScale enhances data management efficiency, reducing costs and energy usage while boosting performance, reliability, and operational efficiency for enterprises.
Sentiment score
7.1
Scality RING offers cost-effective, scalable storage with predictable costs, though enhanced security may increase expenses for added protection.
It does not require much management once you set up correctly, so it saves time, allowing an admin to focus on other work.
Despite being more expensive than Huawei, it is stable and most enterprises accept the price due to its stability.
In terms of Dell PowerScale (Isilon) specifically, we have seen a return on investment due to faster performance than our last few storage arrays, and the general usability is a lot better.
The second cluster of Dell PowerScale (Isilon) gives us flexibility for small things like code upgrades, all the way to scenarios where we have lost this data center or data, allowing us to check if data is still intact on the other side.
I think RING's ability to maintain predictable costs while providing scalable storage solutions impacts our budget by allowing us to pay only for capacity.
For instance, while the cost per gig on a block storage platform may be $2, it's $1.50 for NAS, and only $0.50 for object storage, leading to a remarkable 75% reduction in costs by utilizing the Scality platform.
Scality RING has reduced our operating costs.
 

Customer Service

Sentiment score
7.0
Pure Storage FlashBlade support is praised for responsiveness and knowledge but criticized for slower responses and occasional language barriers.
Sentiment score
8.3
Dell PowerScale customer service is praised for responsiveness and knowledge, though some report mixed experiences with first-level support.
Sentiment score
7.5
Scality RING's customer service is praised for responsiveness, expertise, but could improve in understanding specific setups and simplifying responses.
I would rate them an eight out of ten.
The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years.
Support online is definitely a ten out of ten.
Dell provides support within four hours, and they always fulfill their promises.
They have managed previous issues well.
I've always received responses within the required timeframe, the answers were technically relevant, and there was follow-up—people called us back to check if everything was okay and if the ticket could be closed.
Individuals such as Peter Mikolastik really make a difference by saying, 'Come on, what is the problem? I will help you,' rather than just brushing things off.
Technically, when we have major issues in P1, they are very responsive and we can't say that we don't get a response.

Sentiment score
7.0
Scality RING's scalability has significantly improved, allowing effortless node addition and flexible capacity expansion for enterprise users.
Pure Storage FlashBlade is scalable.
We started on PowerScale with around about 300 terabytes and are now two and a half petabytes, still on the same file system.
That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
Dell PowerScale is highly scalable, as evidenced by the reduced physical hardware and the efficient use of rack space.
Upwards, I think, almost unlimited by what we can imagine.
I've never had issues with scalability.
We are relatively well informed about their new features, what will be implemented in future versions, and the scalability of the solution.

Sentiment score
8.8
Pure Storage FlashBlade is praised for its impressive stability and reliability, with minimal disruptions and consistent uptime even during upgrades.
Sentiment score
8.3
Dell PowerScale (Isilon) offers excellent stability with minimal downtime, efficient clustering, and high user ratings for reliability.
Sentiment score
7.9
Scality RING ensures continuous operation and data accessibility, offering resilience and stability with minimal service disruptions or data loss.
In case there is any issue with any blade, the data is moved to another.
Since we have good protection levels, the data is secured and replicated across the disks.
I assess the stability and reliability of Dell PowerScale (Isilon) as perfect.
I find the product to be resilient and stable. There's no downtime and no crashes.
It is a platform that is very stable at the customer level and does not generate incidents or blockages that you might encounter with standard storage solutions, where you can lose data.
I find that Scality RING is very stable because it allows for many maintenance operations without service loss.
There are factors that can cause Scality RING to become occasionally unavailable, but due to the system's resilience, it is capable of recovering or degrading gracefully.
 

Room For Improvement

Users seek better cloud integration, enhanced deduplication, improved support, protocol enhancements, simpler configuration, and a more intuitive interface.
Dell PowerScale struggles with high costs, complex updates, limited improvements, and lacks cloud and multi-tenant capabilities.
Scality RING faces challenges in administration complexity, requiring improved interfaces, integration, stability, and comprehensive feature enhancements.
Technical support definitely needs significant improvement.
Its configuration should be easier.
Hardware failures under warranty should be addressed within the promised timeline.
I would want to see more AI features with Dell PowerScale (Isilon).
If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened.
Encryption and data security need improvement. We don't have a solution for customers who need confidentiality.
They should prioritize quality over timeliness to minimize customer disruptions and not force customers into a cycle of fixes that interfere with daily work.
What we are currently missing and will be demanding in the new tender is an additional external backup of all data, ideally on a simple system, to safeguard against any severe local incidents so that we still have the data protected elsewhere.
 

Setup Cost

Pure Storage FlashBlade offers high performance and features, justifying its cost with no extra software fees and fixed support costs.
Dell PowerScale is costly but offers fair pricing and scalability, appealing to enterprises with extensive data requirements.
Scality RING's setup and specialized hardware costs are high, but scalable, licensing helps manage expenses for large-scale users.
The pricing of Pure Storage FlashBlade is expensive compared to other products I used from other companies in the past, but one benefit is that they have built-in ransomware protection.
It's quite expensive for the amount of storage we have.
My experience with pricing, setup costs, and licensing for Dell PowerScale (Isilon) shows it's a premium platform, so it's a big amount of money.
The pricing is excellent.
Fortunately, in terms of the license, we are able to expand the disks without having to adjust the license.
In the end, it always depends on how much you pay for it.
Regarding setup costs and licensing, our initial experience is somewhat dated now as we made a comprehensive purchase, including hardware, software, and system setup, which Scality handled at the time.
 

Valuable Features

Pure Storage FlashBlade offers fast, scalable, and user-friendly storage with efficient integration, analytics, and versatility for diverse needs.
Dell PowerScale excels in management, scalability, and performance, offering flexibility, resilience, and cost-effective storage with advanced monitoring.
Scality RING offers scalable, robust storage with S3 compatibility, strong security, and efficient management for diverse environments.
We can plug in many blades, and we can have data up to one terabyte.
The best features of Pure Storage FlashBlade include better throughput and better performance.
Dell PowerScale offers high scalability and stability as well, making it a valuable solution for enterprises.
In our AI initiatives, Dell PowerScale (Isilon) plays a significant role in data analysis, data fusion; principally, it is involved in data analysis, data extraction, and statistical analysis.
Single files are limited to four terabytes in our configuration, however, the system can support up to 16 terabytes, so we can scale based on that too.
When a server is lost, the data is still accessible.
It is even better stored when there is only one copy on a system and there is a second copy on an immutability system, which is almost equivalent to backing it up on tape and taking it offline, making it completely inaccessible.
Scality RING has influenced our approach to scaling in different dimensions by providing a cost-effective solution for the tremendous amount of data we generate every day for each customer.

Featured Reviews

Eric Black - PeerSpot reviewer
The ability to leverage multi-tenancy along with immutability is a huge benefit for us
The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.
Scott Taylor - PeerSpot reviewer
Manages large data sets efficiently with hybrid cloud integration
My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
Sebastien Foucou - PeerSpot reviewer
Leverages seamless data access with efficient storage management
I would improve Scality RING by bundling the Operating System with RING and modernizing the graphical interfaces. As for areas for improvement—if I had to summarize—a technical aspect would be the Operating System part, which today isn't really covered by Scality RING, whereas it is with Artesca. It would be a real advantage for customers to have a bundle that includes both the Operating System and Scality RING, with an install and maintenance model handled by Scality. Secondly, perhaps a more cosmetic point—the graphical interfaces could be modernized a bit. There's been work done on Artesca; maybe it should be extended more to RING. I believe that should come with version 10, so I'm not too concerned. I find RING's cyber resilience against ransomware threats somewhat complicated to assess. The product itself offers sufficient protection, and the features provided via S3 allow you to protect against this kind of attack—provided you implement these features, such as object lock with retention and everything that goes with it. If I had to identify an area for improvement, it would be the OS part—but that doesn't necessarily concern RING, unlike Artesca, which comes bundled with an OS. There's been real work done by the Scality teams to secure the system layer in Artesca. It didn't influence us. We know the product and what needs to be implemented to protect data, and it's part of the best practices we also pass on to our clients.
