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.

Virtualization platform has delivered consistent low-latency SAN storage and 24-7 data access
The stand-out feature for me is the SAN storage because of its ability to deliver consistent sub-millisecond latency, 100% availability, active-active paths, and no performance tuning headache. When maximum users connect at the same time, there is no latency experienced. The main impact of NetApp ASA on my organization is that my data is available 24/7. Whenever I have a requirement over the VPN or inside the LAN, I can access my data anytime and anywhere as per my need.

Quotes from Members

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

Pros

"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"From the first test that we have conducted, we are very satisfied with this solution."
"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"Running on Pure has given us the ability to scale out our SQL environments."
"Data reduction and compression. Sub millisecond latency."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"My advice for anybody who is considering the Dell Unity XT is to just enjoy it."
"Compared to VNX, the Unity is a lot easier to use."
"This is a great storage solution and a product that I recommend."
"There has been no downtime. It has built-in redundancy upon redundancy."
"Delivers High IOPS, but more important, low latency as this is the most important part for our usage."
"It is definitely one of the most robust, solid, well-performing products that I have dealt with, and it is set it and forget it, which is wonderful for my peace of mind."
"The Dell EMC Unity is a small but powerful storage solution."
"Their dedupe functionality is probably the best in the industry. We also find their support model to be good. When we purchase something, we have a very good understanding of how long that product will be supported by them. That helps."
"The main impact of NetApp ASA on my organization is that my data is available 24/7."
"I love the SnapMirror and autonomous ransomware protection features."
 

Cons

"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."
"We had one instance with an eight-hour outage in our primary data center because the upgrade to the controller failed, and the controller redundancy didn't work."
"I think replication is one area that still needs improvement."
"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."
"For large storage needs, it is expensive."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"Improved reporting on the deduplication and compression functionality would be beneficial."
"It can go down from time to time, but it's been pretty solid so far."
"There could always be improvements to the UI."
"The uses of tools to communicate with EMC directly. With EMC, I am not able to connect and resolve issues without assistance, so they can't do unattended maintenance on devices, which would be a massive benefit if they could."
"We have had customers reporting issues with slow responses from the support team."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"They can certainly improve in terms of monitoring. The monitoring could be improved, and more features could be added."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"Dell Unity XT’s price needs improvement."
"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."
"I would like to see more in terms of replication between storage classes. They provide different lines of storage. They have a lower class. They have a capacity class. They have their enterprise class. Currently, we have interoperability at the same plane with ONTAP, but we would like to see some more mix-and-match features."
"NetApp ASA is somewhat expensive, and I believe they should work on the pricing aspect."
"The areas of NetApp ASA that could be improved include features such as the active sync feature that allows a customer to write on either data center A or data center B."
"I'm handling pre-sales and post-sales. From a partner's point of view, the tools that I'm using to create the quote or do the sizing are very slow. The tools, such as hardware universe, fusion.netapp.com, and partnerhub.netapp.com, operate very slowly. These tools should be more efficient as they enter a hung state repeatedly."
"From a partner's point of view, the tools that I'm using to create the quote or do the sizing are very slow."
 

Pricing and Cost Advice

"Pricing is moderate. It is neither cheap nor expensive."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"The pricing is very attractive and it delivers performance for the money."
"Pure came in at a better price point than EMC and performed better than Compellent."
"The solution could be cheaper."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"We have an Evergreen Storage subscription, which I think is a great feature."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"Obtaining a warranty is easy."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"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."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"It's more expensive than other storage vendors such as Dell, Pure Storage, HPE, Lenovo, etc. It provides the value, but some of the customers don't look at the value. They first look at the cost. It should be reduced by 20% to 30%."
"It is pretty good. It is definitely cheaper than Dell EMC. It is cheaper than Pure. It is cheaper than VAST. It is definitely cheaper than HPE. The only one that is on par with NetApp's pricing for enterprise customers is IBM."
