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.

Managing efficiently with user-friendly interfaces for monitoring and managing resources
We normally recommend Dell ECS to enterprise customers and government customers Dell ECS is very easy to handle, primarily because the web UI dashboard and everything is very easy to manage for every customer. They can monitor the DPS, access failures, bandwidth, failed requests, and latency.…
Alan Powers - PeerSpot reviewer
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 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."
"The most valuable feature is Safe Mode."
"I would rate Pure Storage FlashBlade a ten out of ten."
"The product is scalable and easy to expand."
"We have seen a reduction in the total cost of ownership by around 20%."
"The onboarding and integrated monitoring tools are pretty good."
"The main feature I have found to be product replication."
"The performance and support from Dell EMC are very 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 like that the solution is easy to scale and that's its stable."
"I would rate scalability ten out of ten since you buy what you want."
"We face very few hardware failures."
"The performance is good."
"Dell ECS is a cost-effective solution that provides ease of use and availability."
"I have found Dell ECS to be scalable."
"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 feature that we're waiting on is better integration with the cell services."
"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."
"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."
"Pure Storage FlashBlade should improve on more cloud integration."
"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"I want efficiency. FlashBlade doesn't have efficiency now."
"I would also like to see better support for CIFS workloads."
"They need better integration with public clouds along with a better hybrid solution."
"We have had issues when the ECS is expiring or the NetBackup is expiring images."
"Its security can be improved."
"The solution needs to provide better integration between this solution and all other kinds of systems."
"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."
"You should be able to calculate so that when it's full it's 100% full, not just 90%."
"However, hardware failures can impact the cluster, making it read-only."
"The solution could be more cost-effective and secure."
"The major weakness in the solution is that there is no cloud version for Dell ECS."
"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

"Licensing fees are paid yearly."
"I understand that it is competitively priced compared to other brands."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I rate the tool's pricing a seven to eight out of ten."
"The price is a little high."
"We used a reseller for the purchase."
"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 pricing for FlashBlade is between cheap and moderate."
"Dell EMC ECS is too expensive."
"Dell ECS is a cost-effective solution."
"The solution could be cheaper."
"The price of Dell ECS should be reduced."
"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."
"We initially purchased all of the licenses at the same time."
"It is an inexpensive product."
"The product is quite expensive."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
