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

"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"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 most valuable feature is its upgradeability."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"One valuable feature of the Pure Storage FlashArray is its Flash-based architecture, which provides a significant advantage."
"Having an intuitive user interface to get things running is great."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"With so much technological advancement and more coming, the world is their oyster."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"What I feel is that for this product, whether for mid-range customers or high-enterprise customers, it has very good capability in terms of high availability, resiliency, scalability, and user-friendly configuration, which makes it a very good product for customers."
"Dell PowerStore is more cost-efficient than other solutions."
"Since implementing Dell PowerStore, it's very fast and very secure."
"PowerStore helps to simplify IT operations."
"That's the value Dell creates; you invest less, and you get a better ROI."
"Ultimately, Dell PowerStore has been a rock-solid product for us, providing the capabilities we were seeking and yielding both efficiencies and financial value."
"Overall, Dell PowerStore is very competitive in the market and able to beat the competition."
"The best features in Dell PowerStore are that it's easy to manage; for the customer user interface, customers can start learning and provision everything, and manage the system easily."
 

Cons

"If they could make it cheaper, that would be something."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"I would like to see data tiering to AWS."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"A noticeable area for improvement is the support for object storage."
"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"Snapshots are not as easy to access as on a NetApp device."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"The licensing is a little bit high, but the product is very good."
"The solution could be a perfect 10, but sometimes the cost is high when we need to add more enclosures to Dell PowerStore."
"Dell PowerStore doesn't really have a lot of advantages over other products. It has no special features technically. Other products have better management and analytics features."
"If I could improve the product in any way, I would add features that make it look nicer compared to the DisplayPort."
"The design needs to be something similar to Pure Storage. It would be beneficial if there are different color or lighting options for different product casings. Different colors are helpful when working in the data center server room."
"What would make it perfect is addressing the occasional lack of continuity with consultants who are on projects for five to six weeks regarding Dell PowerStore."
"I am not satisfied with Dell PowerStore because of stability. Stability and complexity of some features and configurations are issues with Dell PowerStore."
"More demonstration and training options are needed."
 

Pricing and Cost Advice

"The pricing is reasonable."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"I would rate it a seven out of ten for pricing. It could be improved."
"For us, as the customer, it reduced the price of the management."
"It's priced higher than the market."
"There are no fees for licensing. The hardware is paid for only once."
"Cost-wise, it's been very effective."
"We have seen a reduction in total cost of ownership."
"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."
"HCL Tech has a TLA with Dell, so in terms of price point, we are very competitive. Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market."
"Pricing depends on the model and negotiation. Sometimes we manage to get good discounts, sometimes not."
"The price is high compared to the Tunisian market."
"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."
"There are no separate licenses required as all the basic licenses are included in the bundle."
"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."
"There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."
"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."
