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

"It has improved my organization because now have lower latency, we get fewer complaints from customers, and we see a constant response time."
"Once it's set up, it just runs on its own and only requires the occasional checkup."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"Like I tell everybody else that I deal with, if you want to focus your time on doing more valuable things for your company, and you deal with storage on a day-to-day basis like I do, the best thing you can do is put Pure in your environment."
"We consume less physical storage because of the solution’s deduplication and compression."
"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"The most valuable features are the ease of use and support."
"The performance of the storage is just unbelievable."
"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"We have had no stability issues with the product, including when adding replication on the fly, customer installed code updates, and customer installed DAEs."
"The solution is extremely functional for the price that we pay for it."
"We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution is very easy to set up."
"The solution's initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
 

Cons

"The solution needs an integrated NAS platform, file platform."
"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."
"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."
"Automation could be simplified."
"I would like to see support for NVMe, end-to-end."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"I feel like there is too much automation; the user doesn't have any manual input."
"Currently, the solution fails to support file screening."
"There are some features in VNX that I wish were in the Unity. Storage Groups for isolating LANs and hosts is a big issue."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"I called about an issue where I couldn't get VVOLs registered. It turns out it is a bug in the code and that there is no information about when it will be fixed. It's just not going to work. I was a little miffed about that."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products."
"The monitoring capabilities should be improved."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The features are limited."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"Improvements can be made to the product's performance."
"It is really entry-level. In the next release, I would like to see more functionality."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"Scalability on rack-mount servers is not as good as with Blade servers."
"Usually, when a part fails, we have to replace it and it takes a while."
 

Pricing and Cost Advice

"All storage is expensive so any price improvement would help."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"We have seen a reduction in total cost of ownership."
"We have an Evergreen Storage subscription, which I think is a great feature."
"The best features come included without any additional cost."
"The price is very reasonable when compared to other solutions."
"Pure has been flexible with us on the pricing models."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"The license is not required, but we must renew the support every year, every two years."
"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.""
"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."
"It is a good return on investment."
"From a pricing perspective, this solution is comparable to others on the market."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"Pricing is as high as it has ever been for EMC."
"The best thing about this solution is its price, which reduces our costs."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"The solution's price could be better."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The pricing is fair and low compared to other products in this category."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"It is an expensive solution."
