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.

Ease of implementation and robust performance enhance multi-OEM support experience
We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

Offers flexibility and top-notch technology
You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"Biggest lesson learned: Why didn't I switch sooner?"
"Their support is top-notch, and their NPS scores reflect this."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"For VMware, it has been a humongous savings."
"Their technical support is excellent. It's the best out of any of the vendors we work with."
"I am satisfied with this solution, and we plan to keep using this solution."
"Pure Storage FlashArray has helped us decrease the storage footprint in a significant way; the dedupe and compression that they have is really good, and we're getting about four to ten in the deduplication and compression."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"Replication of the communication object (COB) scenarios"
"The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful."
"It saves us time, it does not require a lot of admin from us."
"This product does bring a ROI, as I have seen it helps them to protect their investment since it is future-proof and scalable, so they don't have to change products every year or so."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"It will certainly help us scale bigger. If I look at the footprint, the VNX's was multi-rack. Now, all of a sudden, we're only at a portion of a rack. And, obviously, if we can scale within the same rack - we can certainly see that by the number of hard drives we've had to put in - we can scale a lot more easily."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"The most valuable feature of this solution is its speed."
"The management software is very good."
"One of the most valuable features is the overall performance it provides. You're able to throw a pile of IOPS at it and it will handle that without much issue."
"The NetApp EF-Series gave our organization easy access to our data bases."
"The hardware and software of NetApp EF-Series All Flash Arrays are easy for us to use."
"The product's initial setup phase can be managed easily and completed in 20 to 30 minutes. It is one of the fastest storage tools that you can implement."
"The solution is very good; it offers very good performance and very good data services to customers."
"We found all of those things in NetApp."
 

Cons

"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"The solution needs an integrated NAS platform, file platform."
"There's always an opportunity for new feature functionality."
"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."
"There was some complexity in the initial setup."
"If there is one thing that I did not appreciate about Pure, it is that between the two different lines, which would be FlashBlade and Everpure FlashArray, there is no easy way to migrate LUNs as far as being able to replicate across those platforms."
"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."
"We ran into some issues with the program at first and we had to work around those issues to fix our problems."
"A rating out of 10 out of 10 is a bit too much because, obviously, no product is super perfect, but I would rate the unity a good nine. What might make it a 10 is a better price."
"There's always room for improvement with the UI. That can be a little cumbersome at times."
"The application's administration needs improvement and become better."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"The payment account area."
"Dell Unity XT’s price needs improvement."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"We need a center related to NetApp in Egypt so that we can deal with them directly."
"I would like to see higher-capacity drives, as they come out; I have heard that 15 TB are out on a different NetApp series. Getting those on the EFs would be nice."
"It needs a better management tool."
"A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series."
"If you're not using DDP, it is a little tedious to configure."
"I guess the user interface could be a little more streamlined."
"Its pricing should be better. Its price is competitive, but they need to improve the pricing. They have different licensing models, which they need to improve. My expectation was cloud integration, which they have, but it is a different license. Therefore, people cannot enjoy it. If I want to use it, I need to pay extra. There is a cost involved for everything, but it should reach everyone. It is similar to having a Rolls-Royce, but you need to pay extra for the key. If you want the key, you need to pay."
"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."
 

Pricing and Cost Advice

"There are no licensing fees or other costs."
"The price of Pure Storage FlashArray is expensive."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"The best features come included without any additional cost."
"It is a cheaper solution."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"Pricing is as high as it has ever been for EMC."
"This solution is a good price for what you get."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"Cheaper pricing is always good. NetApp has been doing everything the right way. They've been figuring out things really well, going in the right direction."
"The price point for EF is considerably lower than the alternatives."
"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."
"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."
"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."
"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."
"Its cost-effectiveness is a major selling point. Compared to other storage vendors, the EF-Series offers excellent value for its price. It's truly a leading product in the industry."
"This solution is not available to many users because the cost is very expensive."
