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

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

"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."
"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."
"This solution has improved the way our organization functions through its reliability and consistent platform for storage and has helped us to simplify storage because the management tools make everything a lot easier."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."
"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."
"I like the speed, and I like the API and how programmable it is."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"I like the SC Series, I enjoy working with it, and with its auto-tiering and hybrid mix of SSDs and spinning disks, customers can revitalize their whole storage system completely without needing expensive all-flash arrays."
"For all the deployments that I've seen or done, its been a rock solid platform."
"It is just as stable as any other high-end solution."
"The most valuable feature is the speed for the end-user."
"It's allowed us to have one hundred percent uptime over the last five years — maybe more."
"Definitely I would like to say to all others, if you want good unified storage solution with satisfactory level ROI just go with Compellent."
"When it comes to mid-range storage solutions, it's usually our preferred solution, from all-flash all the way up to hybrid solutions too."
"It's definitely scalable, definitely fits the majority of our use cases, in high-performance environments such as Oracle, SQL, and so forth."
"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

"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"Pure Storage support could be a little better."
"The solution is not cheap. It's much more expensive than DataCore."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"While the scalability is good, there are certain limitations. Our racks are at their limit, so we do not have the requisite scalability to expand."
"I would rate the SC Series at seven out of ten right now. That might change as future releases come out and more functionality comes into the product."
"From a performance point of view, it's getting a bit old."
"I would like to see an integrated key manager in the controllers. Currently, it's an external product. It would be nice to have the option of having a built-in key for self-encrypting drive features."
"Technical support should respond more quickly because the turnaround time is very high."
"I would like to improve the processing ability."
"For example, for a 4TB SSD, they may charge you seven grand or eight grand. It's expensive."
"To begin with, we were ready to throw it out the window."
"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

"There are no licensing fees or other costs."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"The solution is expensive."
"We have seen a reduction in total cost of ownership (TCO)."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"It's priced higher than the market."
"It is a cheaper solution."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"The maintenance is usually pretty good. It's not like some of the others where they increase it in the fourth, fifth, or sixth years."
"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 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."
"The pricing is reasonable, but 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."
"The pricing of this solution is competitive."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
