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

"It makes things ten times easier."
"What I like most about this solution, is the speed, resiliency and scalability."
"For me, right now, it is the best storage solution in the market, by far."
"Once we solved the data reduction and what Pure does we were hooked."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"The deduplication and compression rates are beyond impressive."
"Pure support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."
"It is easy to use, expand the hard drives, add storage, and set up replication."
"I definitely recommend Compellent to my customers because it is a very good product that is very scalable, it is easy to use, and Dell offers a good warranty."
"For all the deployments that I've seen or done, its been a rock solid platform."
"It is a stable solution; we haven't had any downtime."
"Dell SC Series offers a lot of performance, being one of the best performing storages Dell ever made."
"Its leading feature is the price-performance ratio, which is very good."
"It helps us streamline deployment of VMs."
"I've found the stability to be very good."
"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

"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"There are a lot of things to improve."
"I would like to see box-to-box encryption on replication included in the next release."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"They should work on their upgrades, they're not smooth."
"We need more discount, but it's good."
"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."
"The cost of the solution could be better."
"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"It's not very efficient anymore. There are better products out there."
"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."
"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

"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 pricing is reasonable."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"For us, as the customer, it reduced the price of the management."
"We have seen a reduction in total cost of ownership (TCO)."
"The price is too high."
"The price is reasonable."
"We feel that the pricing is fair and the licensing process was easy for both."
"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."
"Pricing depends on varying life cycles."
"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."
"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."
"This solution could be better priced in comparison with other vendors."
"It has a good price point and offers some value-added enterprise features."
"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."
"We have reviewed many platforms over the years. It is probably the best solution for its value."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
