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.

Managing data protection has become consistent and analytics now drive reliable performance
The most valuable features I find in Dell Unity XT include its robust performance and reliability. My thoughts about its in-line deduplication feature are positive. I would assess the value of Dell Unity XT multi-cloud support for my IT environment as highly beneficial. I do utilize Dell Unity XT data protection features. These features have assisted in ensuring data integrity by providing reliable backup and recovery options. Dell Unity XT integration with VMware helps scalability and availability through seamless operations and enhanced performance. My opinion on its Cloud IQ analytics is that it delivers insightful data that aids in operational efficiency.

Reliable flash storage has delivered strong data reduction and secured sensitive information
There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects. Every storage vendor has certain limitations, and this is not limited to NetApp; it applies to everyone in the industry. I do not see any other significant areas for improvement with NetApp AFF C-Series at this time. NetApp is working on their roadmap, which is solid, and they are developing certain features that are yet to be released.

Quotes from Members

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

Pros

"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"I like its speed. It has all the features that I need."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"Everpure FlashArray has positively impacted my organization, particularly in performance and reliability, as we've had good improvements, making our applications run faster and giving us more confidence that they will not crash."
"I would definitely suggest this solution to a colleague because of the ease of use."
"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us."
"As far as benefits, Dell EMC Unity XT gives us fast access orders for everybody in accounting, and it's working."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"I like its performance and support."
"Performance is a top feature."
"We can get to our applications faster."
"The most valuable features are its performance and simplicity."
"NetApp AFF C-Series is a good product for entry-level flash storage, the system is competitive in terms of pricing, and the value proposition is strong."
"NetApp offers a cost-effective solution with very robust hardware."
 

Cons

"I would like to see them develop the ability to integrate with more AWS services."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"We would always like to see higher performance, and lower pricing is always better."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"I would like to see them lower the costs."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"The price of Dell EMC Unity XT is higher compared to other solutions."
"I would like the UI to look better."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"They should update to the cloud."
"We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes. I don't really have any visibility on anything else. From VMware, I can't look into Unity. From Unity, I can't look into VMware unless I am using virtual volumes, where they integrate together happily, but we are not using that. I would like better integration for non-virtual volume VMware use."
"There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects."
"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."
 

Pricing and Cost Advice

"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"Pure has been flexible with us on the pricing models."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"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 pricing is very attractive and it delivers performance for the money."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"We do not incur additional costs beyond the licensing fee."
"The price is reasonable."
"This solution is a good price for what you get."
"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"Licensing is easy since all the software is included."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"We have to apply for a license for each system."
