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

"This solution is very scalable."
"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"The most valuable feature is it never goes down. We can expand and create volumes."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"Pure Storage FlashArray offers numerous valuable features, such as low latency and high throughput."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example, and for our purposes, we find Unity simple to use."
"We use it to implement all our VDI solutions."
"I like the integration into VirtualCenter. I used to have to add LUNs manually, then scan them in and format them. It does that all for you, all in one, immediate deployment of LUNs."
"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency, and the results were visible in the front-end systems, as all users noticed the improvement and productivity increased because users were able to perform more in the same amount of time."
"Fully automated storage tiering (FAST) cache capabilities allows some FLASH drives to be used to improve the overall performance and reduce the cost of the array versus an all flash or old style spinning disk array."
"It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."
"Ownership simplicity is there. Licensing was straightforward. We've always had good support from Dell EMC, we've never had a problem with them."
"Performance is a top feature."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"Lenovo ThinkSystem DE Series is simple to use"
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
 

Cons

"Pricing could be better in comparison to other solutions."
"In Pure Storage FlashArray, the area with room for improvement is local MFA login."
"Scalability is not an easy option for Pure Storage, so you have to be very careful when you are getting that product for you."
"We have not had a good experience with the IBM device."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"In the next release, I would like to see file-level encryption."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"The scalability of the solution is not as good as it probably could be."
"We would like to see the concept of Storage Groups brought back to this product line."
"It should be lighter. It takes up a ton of rack space."
"Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."
"The price of Dell Unity XT could improve."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"Scalability on rack-mount servers is not as good as with Blade servers."
"The features are limited."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The product could support advanced software integrations."
"The solution could be more scalable, although it suits our present needs."
"It is really entry-level. In the next release, I would like to see more functionality."
 

Pricing and Cost Advice

"The pricing is reasonable."
"The solution is expensive."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"Pure Storage has not helped us to reduce our licensing costs."
"We have an Evergreen Storage subscription, which I think is a great feature."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"Pure has been flexible with us on the pricing models."
"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."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"I liked the price point when we purchased it."
"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."
"This solution offers great pricing."
"Pricing is as high as it has ever been for EMC."
"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."
"It is priced at around or under $50,000."
"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."
"It is an expensive solution."
"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."
"The pricing is fair and low compared to other products in this category."
"The solution's price could be better."
"The best thing about this solution is its price, which reduces our costs."
