Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

User interface offers clarity and detailed information while technical support consistently delivers
The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.
Alan Powers - PeerSpot reviewer
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

"Their technical support is excellent. It's the best out of any of the vendors we work with."
"It is an easy to use product for all of my team members."
"The speed is the most valuable feature of this solution."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"Access speed and power consumption are most valuable."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit we saw, from our very first benchmarks, was that our production databases simply ran twice as fast with no other changes."
"It releases those to new teams within minutes at a very small storage cost amount."
"In terms of performance with mixed workloads, the SC Series is pretty good."
"I think that Dell EMC is one of the best technical support services in Ukraine."
"The technical support is quite good, especially coming from the speed of the technology and support that we received in the past."
"This solution is easy to use."
"The user interface is good, I would rate it a nine out of ten."
"The solution has a wide variety of valuable features. The data progression works well. We use the snapshot functionality quite a bit and really like it."
"It has been one of the most stable products in our data center."
"Technical support is really good. We have had good, high-quality support with our SC Series."
"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 was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"I would like to see support for NVMe, end-to-end."
"We can definitely see a need for it being a multi-controller system for customers who want to scale beyond the current capability."
"We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out."
"Technical support should respond more quickly because the turnaround time is very high."
"It's not very efficient anymore. There are better products out there."
"In the future, I want any box that comes on-premises to have the provision to integrate with cloud storage."
"The interface could be improved. It should have an application point of view."
"This solution could be improved if overall performance was improved and operated with a higher speed and supported a higher volume of RAM."
"The configuration could be easier in Dell EMC SC Series."
"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

"It is a cheaper solution."
"There are no fees for licensing. The hardware is paid for only once."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"There is an annual or perpetual license required for this solution."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"Cost-wise, it's been very effective."
"Pure Storage FlashArray is expensive."
"It is cheaper than NetApp."
"Pricing depends on varying life cycles."
"This solution could be better priced in comparison with other vendors."
"We have the basic license for the use of this solution and it is a permanent license. The overall cost could be less, it is expensive."
"We were able to afford two tiers of flash storage at a price where the competition was giving us one tier or just a handful of discs."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"This product is too expensive compared to others, and I don't see any value in using it."
"It has a good price point and offers some value-added enterprise features."
"There are costs involving the solution, vendor fees and product safety which are additional."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
