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.

Pros

"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"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."
"It is easy to deploy and it's all-flash, so it's very fast."
"The benefits were realized right away. Between the flash array and the compression, you can really see how good it is. Our databases run a lot better now."
"The stability and performance are the best things about the solution."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"Data reduction and compression. Sub millisecond latency."
"It is easy to set up the solution."
"We particularly like the user interface on cloud IQ with this product."
"From a functionality perspective on cost-effectiveness, it is exceeding all expectations."
"Dell Unity XT is a unified box, and it is integrated with VVOL, our software-defined storage."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"It is stable, I have not personally seen any issues when deploying in a customer environment."
"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."
"I can't say enough about the Flex on Demand because it gives you the agility you need."
"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 solution is very easy to troubleshoot, it doesn't take long to deploy, normally comes with a three-year warranty, and has the most features if you compare it to other models."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills; it does not have all the functionality of the DM but it is acceptable, it does its task, and it integrates pretty well."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
"Lenovo ThinkSystem DE Series is simple to use"
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
 

Cons

"I would like to see box-to-box encryption on replication included in the next release."
"There are many features which need to be added, particularly on the replication side."
"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"Pricing could be better in comparison to other solutions."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system."
"Technical support has gotten worse since the merger, for example, response time to SR creation."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"The user interface could use improvement."
"The product’s pricing should be improved."
"We would like to see the concept of Storage Groups brought back to this product line."
"Sometimes the response time is higher than expected due to a lack of issues."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"It would be useful to have structured solutions replicated to other sites."
"Scalability on rack-mount servers is not as good as with Blade servers."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
 

Pricing and Cost Advice

"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"We have an Evergreen Storage subscription, which I think is a great feature."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"The pricing is reasonable."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"Pricing is moderate. It is neither cheap nor expensive."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"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.""
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"The ROI is right where we need it to be. It's a reasonably priced array."
"It is an average priced solution."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"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."
"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."
"The best thing about this solution is its price, which reduces our costs."
"The pricing for this solution is good compared to HP or Dell EMC."
"The solution's price could be better."
"The pricing is fair and low compared to other products in this category."
"We have a five-year contract for providing support."
