MikaelHellström

IT Manager at Regin Dalarna

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Manager, Technical Services at AXS

Offers seamless protocol integration for diverse solutions with flexible API communication

We recommend Dell ECS to customers looking for GeoDrive, archiving, long-term retention solutions, or S3 protocol. It is proposed to sectors like government, education, and banking. Overall, I would rate Dell ECS eight out of ten, as it has shown a lot of enhancement compared to previous solutions like Centera and Atmos.

Alan Powers

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"It's very easy-to-use."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"The initial setup is pretty quick."

"We have seen a reduction in the total cost of ownership by around 20%."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"FlashBlade offers low latency, high throughput, and seamless scalability."

More Pure Storage FlashBlade pros

"It is a stable solution."

"What I like best about this product is that it is a complete solution, both hardware, and software, by the same vendor."

"The most valuable features of Dell ECS are its capability to integrate multiple protocols seamlessly with other Dell solutions like PowerScale and data domain."

"What I like best about Dell ECS is its stability. I also like that you can use it for large-scale data purposes. The solution works fine for me, and I haven't encountered any issues with it."

"The performance is good."

"It's definitely good for unstructured data. In earlier days, we had Centera, so for the DR it's really good. It has load balancing facility, and we're using it with the Kemp Load Balancer."

"I would rate scalability ten out of ten since you buy what you want."

"The performance is good."

More Dell ObjectScale pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"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."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"I have not seen ROI."

"They need better integration with public clouds along with a better hybrid solution."

More Pure Storage FlashBlade cons

"The solution needs to provide better integration between this solution and all other kinds of systems."

"The major weakness in the solution is that there is no cloud version for Dell ECS."

"Dell ECS is not fully compatible with S3, as it supports around ninety percent of S3 APIs, which can be improved. Additionally, sometimes there is an issue with memory where it hangs, and they can improve garbage collection, which takes up a lot of space during cleanup."

"The graphical user interface should offer more options, and the documentation with respect to administration could be improved, as it is quite weak in this product."

"It is a good solution, except for the cost."

"Dell EMC ECS should support segregation of duty, particularly for role-based access controls. Having a single pane of glass for smarter observation and better control mechanism would also make this solution better."

"If Dell ECS would be available as standalone software, so you can use any hardware with it, would make the solution better. It would also be good if Dell ECS had more integrations with other products."

"Dell EMC ECS could improve by having Relational Database Services(RDS) to review progress. Additionally, if the training was provided it would be a benefit, it would be good for our engineers."

More Dell ObjectScale cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

"The price could be cheaper."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"I rate the tool's pricing a seven to eight out of ten."

"The price is a little high."

"I feel that the price could always be lowered."

More Pure Storage FlashBlade pricing and cost advice

"We initially purchased all of the licenses at the same time."

"The charges for this solution are made in blocks of models, which are purchased depending on what features an organization requires."

"The solution could be cheaper."

"We are not paying for the license at this stage."

"The product is quite expensive."

"It is an expensive solution. There is a need to make yearly payments towards the licensing costs attached to the product."

"The solution's cost is quite reasonable."

"It's a lease-based model, so it's capacity-based. We already negotiated the price a lot, but we're still doing that with Dell because somehow the product was not installed successfully, so there was a lot of struggle in the distributor territory between Dell and the environment itself. I would give the solution a 6 out of 10 for the pricing. There's a little room for improvement."

More Dell ObjectScale pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
