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.

Storage solutions accommodate diverse drives and offers good resiliency
Technical support is good. I can log complaints online through the portal and have engineers in line. I can also take dedicated engineers if needed, although this involves a different support cost. As far as my requirements are concerned, it is working fine. There are two or three types of support. Standard support involves logging a complaint and receiving a call from the OEM on the same day, but hardware replacement takes two to three days. Advanced support offers instant replacement without delays. Hardware support terms include calling or emailing the company or logging the call in the portal to receive remote support, or getting a dedicated engineer or account manager from Dell.

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

"This is a very good product at a very good price, with very good support."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"After installing Pure, the processes that would take 40 minutes to two hours to complete are now done in five minutes."
"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."
"The zero latency and high IOPS utilization we observe with it are significantly better than other storage solutions."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"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."
"It's the storage backbone for our virtual environment."
"The setup and installation is much simpler now, because Dell has standardized the configure process."
"The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works."
"The most valuable feature is the speed for the end-user."
"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 is one of the most cost effective systems for us, and we have been able to run it longer than most, getting the most benefit and money out of it."
"We never had a single crash with this product."
"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."
"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

"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"I would like to see box-to-box encryption on replication included in the next release."
"The overall scalability for this product could be improved as well as having a single console to management multiple arrays."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"The solution is expensive."
"It took us a year to get it to stabilize and to get the best out of Pure."
"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."
"We need more discount, but it's good."
"Some menus aren't so intuitive."
"Currently, we are not using this solution extensively because it's becoming a sunset solution."
"The tool's pricing is high and not suitable for medium companies."
"It's definitely affordable. Of course, it would be better if they made it cheaper, even more affordable."
"While there's always room for improvement in everything, I can't really think of a specific feature of the solution that requires immediate attention."
"We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out."
"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

"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"The pricing is very attractive and it delivers performance for the money."
"The pricing of Pure Storage FlashArray is reasonable."
"The best features come included without any additional cost."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"The price of the solution is not expensive."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"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."
"The pricing of Dell EMC Compellent is competitive."
"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."
"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 a very affordable solution."
"Compared to other solutions out there, it's affordable."
"We have found the solution to be affordable."
"This solution could be better priced in comparison with other vendors."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
