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 simplifies storage."
"Biggest lesson learned: Why didn't I switch sooner?"
"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"Go with Pure (or a flasher rate which is similar) because of the ease of management and performance."
"If you need a high-performance storage appliance that is easy to install and maintain, you pretty much can't go wrong."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."
"We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface."
"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."
"Dell Unity XT offers data integration features."
"All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved."
"The architecture is robust; it was the good, old-fashioned storage array, block array for customers, and it's reliable."
"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."
"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."
"Its initial setup process is easy."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"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 simple to use"
"The solution is very easy to set up."
"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."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
 

Cons

"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"It was a little costly."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"There are a lot of things to improve."
"We haven't seen ROI."
"The solution could improve by having a multi-tenant feature."
"The overall scalability for this product could be improved as well as having a single console to management multiple arrays."
"Recently, they released products, sometimes without proper testing, it seems."
"We would like to see the concept of Storage Groups brought back to this product line."
"VNX used to have some features that Unity still doesn't have, so the progress is not that advanced compared to what customers might expect."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."
"Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"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."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"There could be a snapshot feature in the solution."
"Usually, when a part fails, we have to replace it and it takes a while."
"It would be useful to have structured solutions replicated to other sites."
"Its performance could be faster."
"Improvements can be made to the product's performance."
 

Pricing and Cost Advice

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"I would rate it a seven out of ten for pricing. It could be improved."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"It could always be lower, but it's okay."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"Our costs are roughly $200,000 a year."
"The pricing of Dell Unity XT is good."
"Pricing for this product is manageable, though slightly higher than comparable products."
"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."
"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."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"The best thing about this solution is its price, which reduces our costs."
"It is an expensive solution."
"The pricing for this solution is good compared to HP or Dell EMC."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"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."
"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 solution's price could be better."
