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

"It is an easy to use product for all of my team members."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"If I want a product which has reliability and high speed, and Pure Storage is the first name that comes out of my mouth."
"We saw a vast improvement when we switched over to using the Pure Storage model over the XtremIO."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"Reliability and performance are its most valuable feature."
"Pure support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."
"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."
"Everything is sub-5 MS for us. What I've found is that, with all-flash, when an app from my business is slow, I pretty much know it's them and not me. It leads to a performance conversation that has really hit an interesting threshold point where we are better than what they need. So now we get to have that "refactoring your application" conversation a lot quicker because now the performance on the infrastructure side isn't in question anymore."
"What is most valuable about the Dell EMC SC Series system was its reliability."
"It is fast and performs well."
"Technical support is very good. I do use it from time to time and it's always excellent."
"The solution is stable; we've had no problems at all."
"It has been one of the most stable products in our data center."
"Overall, the underlying technology they are using is really great."
"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."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"The technical support is okay, but could be improved."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"A three wave application or multi-wave application synchronization would be an improvement."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Price is about the only thing that's wrong with it."
"The overall scalability for this product could be improved as well as having a single console to management multiple arrays."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"The main disadvantage of Pure Storage FlashArray is the price."
"I would like to see higher compression, dedupe, faster I/O, and bigger drives."
"Dell could improve the upgrading process. It was the lifecycle that made it very short."
"If Dell SC Series could have supported the protocol NVMe over TCP, that would have been great. It does not."
"The connection should be better integrated with the network to offer a better view of the system."
"This product is too expensive compared to others, and I don't see any value in using it."
"Technical support should respond more quickly because the turnaround time is very high."
"In some customer cases, customers experienced more performance or latency."
"For example, for a 4TB SSD, they may charge you seven grand or eight grand. It's expensive."
"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

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"Pure came in at a better price point than EMC and performed better than Compellent."
"There are no licensing fees aside from the support."
"The price is reasonable."
"The price of Pure Storage FlashArray is expensive."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"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."
"Compared to other solutions out there, it's affordable."
"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."
"This product is too expensive compared to others, and I don't see any value in using it."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"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."
"It's a very affordable solution."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
