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.

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

"It’s easy to set up and support is excellent."

"They are quite responsive and our local team was pretty good."

"It overperforms both in terms of storage capacity and throughput, and bandwidth capability."

"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."

"Everpure FlashArray has positively impacted my organization by increasing our agility and the ability to run our environment at high speeds due to the flash storage."

"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."

"The amount of throughput that we're getting is really nice."

"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."

More Everpure FlashArray pros

"Unity is equipment that, if you sell it, you don't have any headaches with it."

"There are some alternatives, but what we've found, working with our partners, for mid-range storage it's probably the best one you could choose."

"User friendly interface Scalability It is shipped with all licensed, included for this product range, no need to buy additional licenses Flexible support plans Prompt answers from EMC support"

"This is a very stable platform, so far zero issues."

"Unity has reduced the complexity and improved productivity tenfold compared to what it used to be."

"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."

"Our end-users are happy with the product, there are no issues."

"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."

More Dell Unity XT pros

"The most valuable feature for us is the ability to move the workload between peers, and it also has a huge advantage of helping us cut down on power consumption."

"The replication and mirroring features are very good."

"I would have to say performance at this point, because the application it is based on is so diverse."

"The database queries on our old system (HP EVA) took nearly 32 hours, but on the new one in under 10."

"Its performance is most valuable. This solution is much faster than other as well as older storage solutions. The performance of the system is very good. We are getting 50 times better experience than the older storages. We are using AFF 300. It also has native cloud integration and most of the features."

"The solution is very good; it offers very good performance and very good data services to customers."

"It's still worth purchasing as the support is good and also the performance is very good."

"We do a lot of in-house, application-dependent type things, where we find the different niches to the different things. Certain things they do better. We've found that it actually does very well on some of our higher-end applications."

More NetApp EF-Series All Flash Arrays pros

Cons

"There are a lot of things to improve."

"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."

"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."

"The GUI could improve, it could be more intuitive. There is hidden functionality."

"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."

"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."

"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."

"I can't see where they can make anything better, unless, of course, they lower their prices even more."

More Everpure FlashArray cons

"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."

"It could always use native replication. Then I could get rid of RecoverPoint."

"Scalability of this solution could be improved."

"They're slow to implement new innovation with their product. EMC doesn't really innovate; they just sit there and wait for other people to innovate, and then they just copy."

"Include cloud-based replication for blocks"

"In some countries, spare part availability is an issue for us."

"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."

"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."

More Dell Unity XT cons

"Here in Egypt, we do not have an official office or central point of support."

"Its pricing should be better. They have different licensing models, which they need to improve."

"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"

"It says NetApp on the badge, but it’s not a NetApp product."

"I would like to shrink it more, if we can. The smaller, the better."

"Better support technicians for CAPP."

"Nonetheless, there are a couple of other things that NetApp hasn't done right."

"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."

Pricing and Cost Advice

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"We do not incur additional costs beyond the licensing fee."

"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"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."

"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."

"All storage is expensive so any price improvement would help."

"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."

More Everpure FlashArray pricing and cost advice

"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."

"We checked both HP and Dell and we determined that Dell EMC was a better option."

"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."

"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."

"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."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

"The solution is very expensive."

"Go with the virtual appliance versus the hardware."

More Dell Unity XT pricing and cost advice

"They need to improve its pricing. The storage market is dying. So, they need to improve the price because it should reach all people. NetApp is one of the top ones, and they are charging a little bit of royalty as compared to other storage solutions."

"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."

"One has to opt for a perpetual-based licensing model for one year or three years. After three years, you need to renew the license."

"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."

"It's a lot cheaper than what the other vendors have for the same type of environment. It saves us money."

"Adding more capacity will increase the cost."

"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."
