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

"The support team is available all the time and they seem to know what they are doing."
"It simplifies the overall management. We don't have to worry about storage anymore."
"The white glove customer service that I get is their greatest value."
"If you factor in the ease in terms of operations, as well as the cost of the array compared to other solid state arrays, it becomes a clear positive for Pure Storage."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"I would definitely suggest this solution to a colleague because of the ease of use."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."
"The most valuable feature is the ability to replicate. We are running a financial company and it needs to be available 24/7. We can't afford any downtime."
"It's very scalable, especially with federation. If you outgrow the number of spindles that a unit can support, depending on the model, you can go into federation."
"Definitely I would like to say to all others, if you want good unified storage solution with satisfactory level ROI just go with Compellent."
"Technical support is really good. We have had good, high-quality support with our SC Series."
"One time, we had a drive fail and we were notified before we even saw it on the device."
"The product offers good performance and is quite powerful."
"It's definitely scalable, definitely fits the majority of our use cases, in high-performance environments such as Oracle, SQL, and so forth."
"Dell SC Series' most valuable features are performance and network facilities. We have no issues with its integration. The tool helps to visualize servers."
"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

"Most of our upgrades have not been as smooth as they should have been."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"I would like to see more cloud integration."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"The price could be improved."
"The tool's pricing is high and not suitable for medium companies."
"We can definitely see a need for it being a multi-controller system for customers who want to scale beyond the current capability."
"I would like to improve the processing ability."
"I would like the ability to monitor and manage the storage. The web GUI is not fully there."
"The configuration could be easier in Dell EMC SC Series."
"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."
"In some customer cases, customers experienced more performance or latency."
"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

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"Pricing is very competitive, and it's better than other competitors."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"We purchased a license to use this solution and we pay for the storage ourselves."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution."
"Pricing depends on varying life cycles."
"The SC Series was priced fairly. I wouldn't call it either expensive or cheap because we had a very tight budget, so if they were able to fit in that type of budget, they met our expectations."
"The pricing of Dell EMC Compellent is competitive."
"This product is too expensive compared to others, and I don't see any value in using it."
"We have reviewed many platforms over the years. It is probably the best solution for its value."
"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 have found it to be affordable. Comparing the cost with other hardware, it seems to be right in line with the compute and the storage that we get with it."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
