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

"Now they are trying to add more and more applications because they're getting better performance and stability."
"The mobile app is very helpful."
"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"I am satisfied with this solution, and we plan to keep using this solution."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"From my experience, EMC provides good support, and Dell's service is very good."
"The solution overall has high performance."
"It has reduced the latency in application and database reads and writes... All-flash, it's fast. We have the 650 model which is all-flash, upgraded from VNX. It just flies."
"There are some alternatives, but what we've found, working with our partners, for mid-range storage it's probably the best one you could choose."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"Overall, I've had a very good experience with the solution so far."
"It works great, has a very simple interface that we're comfortable with, so it's a good product for us."
"The All-Flash models are intuitive and easy to work with, in addition to providing high IOPS with low latency to support Business Critical applications."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"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. It integrates pretty well."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution's initial setup process is easy."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"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."
"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."
"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 the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"Most of our upgrades have not been as smooth as they should have been."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"The technical support is okay, but could be improved."
"One requested enhancement yet to manifest is the scheduling of snapshot replications."
"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"It is missing some features, like deduplication."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"The user interface could use improvement."
"I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance."
"Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"In Brazil, price and native Unity migration tools are not very good yet."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"There could be a snapshot feature in the solution."
"The solution could be more scalable, although it suits our present needs."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Scalability on rack-mount servers is not as good as with Blade servers."
"The features are limited."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
 

Pricing and Cost Advice

"There is always room for negotiation."
"I don't know the exact cost but it's around $1,000."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The price was more favorable than Dell EMC."
"It's priced higher than the market."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"We have an Evergreen Storage subscription, which I think is a great feature."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"From a pricing perspective, this solution is comparable to others on the market."
"Licensing is easy since all the software is included."
"The solution is very expensive."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The pricing for this solution is good compared to HP or Dell EMC."
"It is an expensive solution."
"The solution's price could be better."
"The best thing about this solution is its price, which reduces our costs."
"We have a five-year contract for providing support."
"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 pricing is fair and low compared to other products in this category."
