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

"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"It releases those to new teams within minutes at a very small storage cost amount."
"The support has been very good from Pure Storage FlashArray."
"From the first test that we have conducted, we are very satisfied with this solution."
"It simplifies the overall management. We don't have to worry about storage anymore."
"The best features of Pure Storage are their support and analytics."
"All use cases for Everpure FlashArray are anything that requires a SAN should use it because it is the easiest thing on the market."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"The product offers good performance and is quite powerful."
"Easy management of volumes: You can create volumes and easily assign them to VMware clusters, increasing their size."
"It was very easy to install, maintain, and provides excellent manageability."
"The technical support is quite good, especially coming from the speed of the technology and support that we received in the past."
"The most valuable feature is the speed for the end-user."
"For us, being enterprise-critical and having applications that process lots of transactions every day, we can't take chances on our applications and the ability of our storage to be reliant."
"The solution is stable."
"The setup and installation is much simpler now, because Dell has standardized the configure process."
"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 like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"A three wave application or multi wave application synchronization would be an improvement."
"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."
"It falls far short of protocol support."
"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."
"Improved reporting on the deduplication and compression functionality would be beneficial."
"It is a bit expensive."
"This product should be a lot more user-friendly."
"Matching color coding during zoning is sometimes a little bit annoying."
"Compared to other solutions out there, it's affordable. It would be nice if the cost was even lower."
"I would like to have 100% functionality through the web app."
"In terms of what could be improved, I would say the lack of reporting would be the main issue."
"The configuration could be easier in Dell EMC SC Series."
"Some menus aren't so intuitive."
"The cost of the solution could be better."
"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

"Our costs are around $100,000."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"The cost has room for improvement."
"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 price of Pure Storage FlashArray is expensive."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"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."
"The pricing of this solution is competitive."
"It's a very affordable solution."
"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."
"The pricing of Dell EMC Compellent is competitive."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"Pricing depends on varying life cycles."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
