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

"Compared to other storage boxes, Everpure FlashArray is very useful because it is cost-effective and requires less work."
"It's easy to use, and the maintenance upgrades to get free controllers work really well."
"The support team is available all the time and they seem to know what they are doing."
"The scalability is good."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"The support has been very good from Pure Storage FlashArray."
"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"They find the performance amazing from what they're coming from."
"We have resolved IT challenges with this solution; it sped up our environment, and we went from spinning disk to all-flash, which reduced our footprint."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."
"Dell Unity XT is user-friendly and easy to use."
"I would definitely recommend Unity because, compared to VNX and other storage solutions, it is the easiest way to deploy for VMware and physical operating system services."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"The main impact of NetApp ASA on my organization is that my data is available 24/7."
"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."
"I love the SnapMirror and autonomous ransomware protection features."
 

Cons

"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."
"I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"The price of this product can be more cost-effective."
"We have only used tech support to replace drives that have gone bad. But our experience has not been so good."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"NetApp ASA is somewhat expensive, and I believe they should work on the pricing aspect."
"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."
"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 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."
"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

"Our costs are around $100,000."
"The price of Pure Storage FlashArray is expensive."
"FlashArray is expensive, but the quality justifies the price."
"Pure Storage has not helped us to reduce our licensing costs."
"I don't know the exact cost but it's around $1,000."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"I would prefer that they lower their pricing."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"It is an average priced solution."
"The price is good for commercial grade storage arrays."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"This solution offers great pricing."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."
"The ROI is right where we need it to be. It's a reasonably priced array."
"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."
"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%."
