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 have seen a good reduction in the amount of total storage space that we're using because of the deduplication."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The reliability is very good."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit we saw, from our very first benchmarks, was that our production databases simply ran twice as fast with no other changes."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"The best features Everpure FlashArray offers are the speed and dependability, which are the main features that we get from Pure; it is faster than its competition, and we do not have any documented downtime from it ever."
"We noticed a dramatic increase in application performance when moving it from NetApp to Pure Storage."
"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"With so much technological advancement and more coming, the world is their oyster."
"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"
"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."
"It performed great originally, and when it performed great, it was awesome."
"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."
"With Dell PowerStore, we're getting close to 200,000 IOPS, which has doubled our performance."
"As a primary storage, it has all the features that our customers need, with only minor tweaks or enhancements needed here and there."
"I would assess the timeframes to deploy it as efficient."
"Benefits of Dell PowerStore compared to Unity 400 and 650F, which we were previously using, are significant: we benefit from extensive deduplication for non-database applications, which saves us a considerable amount of costs, and the performance has improved dramatically due to advancements in technology, such as TLC disks and NVMe technologies."
"The most valuable aspects of Dell PowerStore are integration with VMware and reliability."
"The most valuable features of Dell PowerStore are the support for NVMe and SCM, which provides end-to-end performance and high IOPS, minimizing latency. It is a full-fledged storage solution."
"It has its own file formatting protocol, which saves a lot of space."
"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

"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."
"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."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"The main disadvantage of Pure Storage FlashArray is the price."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In future releases, I look forward to more AI features."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"The customer support is slow and has room for improvement."
"Some of the data metrics we get out of Pure from a support perspective online are a little bit more robust than the Dell PowerStore metrics, but it's not a negative against Dell."
"The only weirdness is we have a 7920 that trying to get into with the password is just not the same as the other enterprise models will have it."
"The primary limitation is that Dell PowerStore typically uses SSD disks, making it more expensive than alternatives."
"The performance is good, but the management experience and user interface are lacking."
"There are some management issues in Dell PowerStore. I have managed several pieces of Dell PowerStore's hardware area, and I could feel that it was almost like a step back in certain areas when it came to the management interface."
"I would like to see additional features or functionalities for the Metro in Dell PowerStore, especially because there are a few workloads still not supported."
"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached."
 

Pricing and Cost Advice

"Pure has been flexible with us on the pricing models."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"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."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"Pure Storage FlashArray's pricing is very competitive."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"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."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"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."
"The pricing is good. There's no need to pay for a license; it's all-inclusive."
"The rate is always too high. Nobody likes paying for it. I have not seen a client yet who says that the price should be higher. Initially, people look at it, but when they see what the benefits are, it is a no-brainer. We can give them good pricing at the outset."
"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."
"In the pricing and licensing department, the product is always too expensive."
"If we use the 500 or 1000, the licensing and pricing are reasonable. PowerStore can compete with any vendor and the price isn't that expensive."
"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."
"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."
"The solution's price was comparable to other products for the use case, size, and setup."
