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

"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"It simplifies the overall management. We don't have to worry about storage anymore."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The product cheaper compared to other solutions concerning the technology that they are using."
"If you're interested in using this solution, I recommend that you do the same — see if you like it."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"We have perfect run through times and latency."
"I used to have to manually sync storage from server to server, for multiple clusters and database storage for disaster recovery but now, that's all automated."
"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 performed great originally, and when it performed great, it was awesome."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"Data Compression: Up to 80% space reduction in the database"
"We use IntelliFlash products for larger environments, like Qatar Airways."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"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."
"The PowerStore's compression ratio is even higher than the Unity system."
"The most valuable feature of Dell PowerStore is the ease of deployment and general use."
"The most valuable features in Dell PowerStore are the Metro Volume features that are built-in without requiring an additional component."
"From a CAPEX perspective, the main advantage is data reduction, and the second advantage is the DRE feature, which allows a single drive to be used for storage, also representing an OPEX option, because traditional configurations require four or five drives but Dell PowerStore can function with a single drive based on customer requirements, which is a major advantage."
"The solution's technical support is excellent. I rate the technical support a ten out of ten."
"Moving and optimizing workloads within the cluster is quite easy based on my experience with Dell PowerStore."
"Since implementing Dell PowerStore, it's very fast and very secure."
"The biggest trust element is people are very happy to depend on a Dell infrastructure."
 

Cons

"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"If there is one thing that I did not appreciate about Pure, it is that between the two different lines, which would be FlashBlade and Everpure FlashArray, there is no easy way to migrate LUNs as far as being able to replicate across those platforms."
"I would like to have support available in Spanish."
"The solution needs an integrated NAS platform, file platform."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I would like to see data tiering to AWS."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Snapshots are not as easy to access as on a NetApp device."
"The monitoring matrix and its dashboard need work."
"One improvement I would suggest relates to the service that pings Dell when there's an issue. I would say it needs to be more transparent."
"The UI should be a little more user-friendly to manage."
"I have already faced competition due to the ransomware feature that Dell does not have as a built-in feature in the storage."
"It's also only supported with a limited amount of switches."
"The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal."
"There is an issue with Dell PowerStore related to future expansions which are software-related."
"We question that quite often because they have been increased by thirty to thirty-five percent every quarter for unexplained reasons, and that definitely does not go down well with customers."
"Dell PowerStore has deduplication, but it may need more enhancement because in our case, it was not as efficient as Dell Data Domain."
 

Pricing and Cost Advice

"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"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."
"The price is too high."
"It's a good price point and it's a solid product for the price."
"Pricing is very competitive, and it's better than other competitors."
"Pure Storage FlashArray's pricing is very competitive."
"The best features come included without any additional cost."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I rate the price of Dell PowerStore a seven out of ten."
"The software features are included in the pricing without any additional purchase requirements."
"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."
"The pricing rates at seven out of ten as it is considered overpriced. Entry-level models are reasonably priced, starting around $30,000 for a base model with 6 drives. However, upgrades become costly - adding 6 additional drives can cost another $30,000."
"Dell PowerStore is not a cheap solution."
"In the pricing and licensing department, the product is always too expensive."
"There are no separate licenses required as all the basic licenses are included in the bundle."
"The price is high compared to the Tunisian market."
