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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

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

"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"Service and support is phenomenal."
"We have integrated the solution with VMware, and the process was seamless."
"This storage has to be the most well thought out and effective storage that I have had the privilege to work with."
"We chose Pure Storage because it had the best performance of all the products that we tested."
"If you factor in the ease in terms of operations, as well as the cost of the array compared to other solid state arrays, it becomes a clear positive for Pure Storage."
"Technical support is very good."
"The pricing of the product is very competitive to others in the market for Flash and NVMe storage, and from an ROI standpoint, if you consider compression and de-duplication and all that, you get a pretty good ratio."
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"With so much technological advancement and more coming, the world is their oyster."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"I am saving costs because I am getting better performance and deduplication rates."
"Dell PowerStore is designed to consolidate the different product lines, VNX and Unity, into a single frame, and is one of the top-tier storage solutions for mid-enterprise level, featuring unique innovations such as AppsOn, which allows you to run your VMs directly on Dell PowerStore without needing additional hardware while facilitating faster performance and reducing hardware costs."
"It's really good, price-wise. It's cost-effective."
"The best features in Dell PowerStore are that it is not too difficult to configure, at least for those implementations that I was part of, and it basically just works."
"My experience with deploying Dell PowerStore was that the installation was straightforward."
"The biggest trust element is people are very happy to depend on a Dell infrastructure."
"Dell PowerStore is designed for large enterprises that require storage solutions with high availability and disaster recovery capabilities, and I believe Dell PowerStore is the best solution for this purpose."
"In my view, if a storage array requires constant monitoring or 'whispers in your ear' every five minutes with issues, it isn't doing its job. Because the sites currently running PowerStore are silent and stable, I consider the Return on Investment to be excellent. It provides exactly the peace of mind we are looking for."
 

Cons

"Self-backup is the only feature lacking in this solution."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"The price of this solution could be improved."
"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."
"There was some complexity in the initial setup."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"In future releases, I look forward to more AI features."
"Snapshots are not as easy to access as on a NetApp device."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"Where the system needs to improve is by adding more enterprise features like replication on other sites."
"We are happy with the service in general. The only thing would be the price of the platform."
"Products that are not native sometimes cause migration issues."
"Dell PowerStore is a very good product, and we would love to sell more of these products. Pricing is the only thing that could still be improved."
"The UI can be complex."
"Dell PowerStore customer service is good, but sometimes they usually take a lot of time to understand the issue."
"The storage could be improved. I would like a feature for how to best secure an appliance and the storage since we are connecting the container to the public cloud. I would like them to develop another level of security, making it more secure than from what they have now."
"There are some issues in the firmware and operational system for Dell PowerStore, such as certificate issues from legacy firmwares."
 

Pricing and Cost Advice

"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"Pure has been flexible with us on the pricing models."
"Pricing is moderate. It is neither cheap nor expensive."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"There is always room for negotiation."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"Pure Storage FlashArray's pricing is very competitive."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."
"The pricing is good. There's no need to pay for a license; it's all-inclusive."
"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."
"As compared to others, PowerStore is cheaper."
"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"
"Dell PowerStore is not a cheap solution."
"The solution's price was comparable to other products for the use case, size, and setup."
"The software features are included in the pricing without any additional purchase requirements."
