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

"It's very fast, easy to use, and the cloud-based management is good."
"Everpure FlashArray is very user-friendly, easy to learn, and makes it easy to identify issues while providing more redundancy on both the controller and host sides."
"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."
"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"The most valuable features I have experienced are the centralized management and redundancy under speed of the right disk."
"The performance is great."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"The most valuable feature of this solution is the support."
"Stable flash storage platform with good scalability, efficiency, and speed."
"It is a good value given the benefits it provides."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"Dell Unity XT offers data integration features."
"Our customers have a competitive edge when compared to the other solutions in the market."
"The most valuable features of this product are its reliable storage and its archiving feature."
"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 all-flash feature is really boosting up the VMware. It is helping our virtual machines to perform better."
"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."
"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."
 

Cons

"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."
"The cost of the storage needs improvement."
"The file functionality could be better."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"We haven't seen ROI."
"The price of Pure Storage FlashArray could be better."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."
"We cannot connect directly with Dell due to sanctions."
"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."
"The interface and configuration could improve."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"In terms of what could be improved, I would say its capacity and its connection."
"Firmware Upgrades in EMC Unity require you to manually download OS and Drive firmware, this should be integrated (Nimble does this). When you order an EMC Unity, you have to specify the block size. This is weird for me and even weirder that you cannot change this afterwards, you should be able to specify per LUN/datastore (Nimble does this as well)."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"Yes, we had an issue in January with a Service Processor rebooting unexpectedly."
"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."
"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."
"NetApp ASA is somewhat expensive, and I believe they should work on the pricing aspect."
"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

"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"Cost-wise, it's been very effective."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"It's expensive, but you get what you pay for."
"It's a good price point and it's a solid product for the price."
"The licensing is $100,000."
"Pure Storage has not helped to reduce our HANA licensing costs."
"You get what you pay for. It is expensive, but it really works."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"The ROI is right where we need it to be. It's a reasonably priced array."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"The support you're getting with it is probably an underestimated value that comes with the box you're buying."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."
"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."
"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."
