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

"If you need faster storage and a good product, this is the one you should go ahead with."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"This is the best all-flash storage array on the market."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"I would recommend Pure Storage FlashArray to other users because, first, the speed that I get with Pure Storage FlashArray is not remotely possible with any other product at this price range, and second, the support is absolutely fantastic."
"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."
"The performance of the storage is just unbelievable."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"The complete block and file sharing are the most usable features."
"Scalability is good."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5."
"As far as cost is concerned, it does great deduplication, and from a storage perspective, we save money being able to dedupe right on the disk."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"We use the Unity as the SAN for our data center; it's where all of our data lives right now for our main office, and it has exceeded our expectations."
"The solution is extremely functional for the price that we pay for it."
"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."
"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."
"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."
"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."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"The solution is very easy to set up."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
 

Cons

"In the next release, I would like to see file-level encryption."
"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."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"Going forward, don't complicate things for the customers."
"There's always room for improvement with the UI. That can be a little cumbersome at times."
"The pricing is a bit higher than expected, and this is an area where I see room for improvement."
"The interface and configuration could improve."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"It could always use native replication. Then I could get rid of RecoverPoint."
"Issues with slow responses from the support team."
"Ordering is easy, but the processing site and working with those companies was difficult."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"There could be a snapshot feature in the solution."
"The product could support advanced software integrations."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Usually, when a part fails, we have to replace it and it takes a while."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
 

Pricing and Cost Advice

"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."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"The pricing of Pure Storage FlashArray is reasonable."
"We are finding the TCO of flash to be lower than SSD implementations."
"The licensing is $100,000."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"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.""
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"From a pricing perspective, this solution is comparable to others on the market."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing is fair and low compared to other products in this category."
"The pricing for this solution is good compared to HP or Dell EMC."
"We have a five-year contract for providing support."
"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 solution's price could be better."
"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."
