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.

Mahmoud Abuherra

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.

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

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"The most valuable feature of this solution is performance."

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

"The most valuable features are the Metro clustering, and disaster recovery."

"We can capacity plan at a greater level than we used to."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"I would rate Pure Storage FlashBlade a ten out of ten."

More Pure Storage FlashBlade pros

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

"The support is good."

"It is a stable platform."

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

"Dell's technical support team is good."

"The performance is good."

"It's my understanding that the initial setup is straightforward."

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

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

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

"The solution is expensive."

"I would like to see better integration."

"I would like to see more monitoring capability included in the next release of this solution."

"Pure Storage FlashBlade should improve on more cloud integration."

"The speed could be improved."

"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."

"I would like to see more deduplication."

More Pure Storage FlashBlade cons

"They do not have complete documentation, which is very weak and could be improved."

"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."

"We have had issues when the ECS is expiring or the NetBackup is expiring images."

"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."

"The solution’s stability could be improved."

"Its security can be improved."

"There is room for improvement in the DPI reports, as they could be made more user-friendly."

"However, hardware failures can impact the cluster, making it read-only."

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

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

"The product is very expensive."

"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."

"We used a reseller for the purchase."

"Our customers have seen a reduction in TCO."

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

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

More Pure Storage FlashBlade pricing and cost advice

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

"The price of Dell ECS should be reduced."

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

"Dell EMC ECS is too expensive."

"If I remember correctly, Dell ECS is an appliance, so if you buy Dell ECS, you also have to buy the hardware, while IBM is standalone software, so you can buy IBM as software only without needing to buy the hardware. On a scale of one to five, I'm rating the pricing for Dell ECS a four."

"The solution could be cheaper."

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

More Dell ObjectScale pricing and cost advice

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

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