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.

Resilience has supported proactive management and secured audit readiness across multiple sites
The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would highly recommend this solution; it has all the features we need and tests all the software solutions that are currently available and that will be available in the future."
"The most valuable feature is replication."
"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."
"The initial setup was really straight forward."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"We only have storage provisioning, so the provisioning feature is good. The compression and deduplication are good."
"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."
"The solution's migration feature is very valuable, but the most valuable thing is that more features appear with every iteration of the software."
"The data encryption is good and available in a standard license. There are snapshot and backup capabilities."
"As far as data resiliency with Dell PowerStore, I have not had any problems with corruptions."
"Dell PowerStore is more cost-efficient than other solutions."
"The most valuable feature is the functionality of the integration between the storage and the domain."
"We used Cloud IQ. The central management and outside support functionality were great since we had systems all over the world."
"The most impactful feature is the data reduction."
"I've tested quite a few storage systems, and I find Dell PowerStore really highly suited to modern, diverse environments."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"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."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"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 simple to use"
"Its initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
 

Cons

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."
"There are a lot of things to improve."
"Currently, the solution fails to support file screening."
"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."
"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."
"A noticeable area for improvement is the support for object storage."
"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."
"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 support team should have more people with experience in the solution's installation process, as it is one of the areas where I see certain shortcomings."
"We are happy with the service in general. The only thing would be the price of the platform."
"My only concern is with the procurement process, which takes longer when we procure Dell products."
"I have realized nothing exemplary from using Dell PowerStore, except hat the user interface is clunky, and we've had issues with that."
"As a partner, I'd like to be added to each customer's CloudIQ to take a look."
"The biggest con could also be that same relationship, as it can be difficult to move away from them with the entire Dell stack."
"Sometimes, you have to go back and forth with the technical support team, where they want you to do something you've already done."
"Horizontal scaling has room for improvement."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"The features are limited."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"Improvements can be made to the product's performance."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"The solution could be more scalable, although it suits our present needs."
"There could be a snapshot feature in the solution."
"Scalability on rack-mount servers is not as good as with Blade servers."
 

Pricing and Cost Advice

"The price is very reasonable when compared to other solutions."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"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 seen a reduction in total cost of ownership (TCO)."
"The solution could be cheaper."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
