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.

Ease of implementation and robust performance enhance multi-OEM support experience
We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Running on Pure has given us the ability to scale out our SQL environments."
"It has made working with storage as easy and simple as it should be."
"The features that are there now are really what we need."
"I have never experienced an outage with the product or had any support that was below excellent."
"What I like most about this solution, is the speed, resiliency and scalability."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"Pure Storage is seen as a visionary company with leading edge technology."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"It saves us time, it does not require a lot of admin from us."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"I like the ease of configuration, the quick setup and the fact that it seems to be hardened. We haven't had any issues with them. In terms of simplicity of ownership, once they're running you don't have to touch them. They're also simple to manage. We came from the VNXe 3200s so it's very similar."
"Technical support is very good."
"The initial setup is very easy. I would rate my experience with the initial setup a nine out of ten, with one being difficult and ten being easy."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
 

Cons

"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"Reports of performance and LUN utilization could be improved."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"Pricing could be better in comparison to other solutions."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Scalability of this solution could be improved."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"Maybe deduplication would be something that would be better to have."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information."
"In terms of what could be improved, I would say its capacity and its connection."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"A customer had to buy VMX because Unity didn't have WORM."
"The price has room for improvement."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The product could support advanced software integrations."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"Improvements can be made to the product's performance."
"It would be useful to have structured solutions replicated to other sites."
 

Pricing and Cost Advice

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"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..."
"I would rate it a seven out of ten for pricing. It could be improved."
"The price of Pure Storage FlashArray is expensive."
"Pricing is very competitive, and it's better than other competitors."
"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."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."
"The pricing of Dell Unity XT is good."
"We have to apply for a license for each system."
"The solution’s pricing is competitive."
"The price is very reasonable."
"Obtaining a warranty is easy."
"We purchased a five-year warranty."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"It is an expensive solution."
"The best thing about this solution is its price, which reduces our costs."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The solution's price could be better."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
