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.

"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."
"It has improved my organization in the way that we have high reliability and faster access to our data."
"Do it. I have zero reservations about recommending Pure to anyone who is looking for some really good all-flash."
"Go with Pure (or a flasher rate which is similar) because of the ease of management and performance."
"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."
"We replicate between SAN to SAN for a lot of features and supportability. It also helps us when we want to upgrade to a newer SC Series or move the data from one data center to another."
"Connecting it up, you can run it within a few hours."
"Component support was great; on a scale of one to ten they were a ten, they were always helpful."
"I think that Dell EMC is one of the best technical support services in Ukraine."
"The technical support is great, we have 24/7 support with a four-hour response, they are responsive and they stay to help until the problem is resolved."
"Definitely I would like to say to all others, if you want good unified storage solution with satisfactory level ROI just go with Compellent."
"It was very easy to install, maintain, and provides excellent manageability."
"This has been one of the most reliable storage systems that I have ever used."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"I would like to see more cloud integration."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"I would love for them to have a hyper-converged solution."
"We would always like to see higher performance, and lower pricing is always better."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"The price of this solution could be improved."
"In the next release, I would like to see file-level encryption."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"It would be helpful if the solution offered higher performance, at least on the back end."
"For example, for a 4TB SSD, they may charge you seven grand or eight grand. It's expensive."
"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms."
"I don't think the solution is very scalable."
"The administration and support (on the way that they delivered) was a little bit slow."
"The interface could be improved. It should have an application point of view."
"Honestly, we were initially struggling with the integration with VMware (but it was fixed with the VMware 6.5) and, then, it was around a 10GB network."
"It's not very efficient anymore. There are better products out there."
"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."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"The pricing of Pure Storage FlashArray is reasonable."
"The cost has room for improvement."
"The solution could be cheaper."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"The best features come included without any additional cost."
"We have found the solution to be affordable."
"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's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."
"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."
"The pricing of this solution is competitive."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"Compared to other solutions out there, it's affordable."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
