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.

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

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

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"The main feature I have found to be product replication."

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

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

"Using this solution has made our backups more reliable."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"It uses the same platform for connectivity so integration is seamless."

More Pure Storage FlashBlade pros

"This product is very competitive."

"It is a stable solution."

"I have been satisfied with the stability."

"The scalability is good."

"The stability is the most valuable aspect of the solution."

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

"I have found Dell ECS to be scalable."

"Dell ECS provides compatibility between on-premises and cloud-based storage, supporting protocols such as S3, which is commonly used in cloud storage, enabling integration between on-premises storage and cloud storage."

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

"The features provided for SMB customers are limited."

"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."

"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."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"I would also like to see better support for CIFS workloads."

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

"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."

"The documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

"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."

"Dell ECS could improve the price of the solution. It is expensive."

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

"You should be able to calculate so that when it's full it's 100% full, not just 90%."

"In Taiwan, they don't have professional technical support."

"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."

"While there can be occasional issues with routing to the wrong region that lead to slight delays, it's typically business as usual."

"There are some limitations with integration with certain cloud providers, particularly with Google Cloud Platform in Saudi Arabia."

More Dell ObjectScale cons

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

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

Pricing and Cost Advice

"The product is very expensive."

"I understand that it is competitively priced compared to other brands."

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

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"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."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"The price could be cheaper."

"The pricing for FlashBlade is between cheap and moderate."

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."

"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 product is quite expensive."

"It is an inexpensive product."

"The solution's cost is quite reasonable."

"The price of Dell ECS should be reduced."

"Dell EMC ECS is too expensive."

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."
