Featured Reviews

Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
Nabeel Sayegh - PeerSpot reviewer
Supercharges enterprise storage by way of highly optimized hardware, comprehensive data management and a feature rich interface.
During their early years, I was a member of Pure's Customer Advisory Board. In addition, when we first adopted Pure, they did not have replication GA yet. We got into their beta testing program and help them work out certain issues with that technology. One weakness I can say the array has, still to this day, is limited control on scheduling snapshots. Depending on the type of replication schedule you are building, you may or may not have control on specifying the start time of a given replication schedule. This is not a very big problem in the grand scheme of things, but something nonetheless that has bothered me about the scheduler in general. Another area for improvement would be automatic host alias creation. Other platforms such as EMC Unity/PowerStore will automatically detect the host name, create a alias for it and associate the logged in HBA's to it. Pure does not do this for you and as a result, requires manual configuration. This can be very time consuming especially when you are deploying a large number of new servers.

Quotes from Members

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

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Technical support has been helpful and responsive."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The initial setup was extremely simple and straightforward."
"The most valuable feature of this solution is reliability."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The solution overall has high performance."
"It is very stable."
"We can sleep at night because the support is great."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"The complete block and file sharing are the most usable features."
"It has helped us be able to use less administrators per device or system. Therefore,we are more streamlined."
"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."
"Because of the encryption, we have different storage and the encryption can go over both."
"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..."
"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"I have seen a huge increase in speed and performance on our databases."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"Pure Storage FlashArray offers numerous valuable features, such as low latency and high throughput."
"The amount of throughput that we're getting is really nice."
"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."
 

Cons

"There are some challenges with data encryption and reduction."
"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The software layer has to improve."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"They could add more support for file storage and different types of storage."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"Scalability for the 650F is good, but I was expecting a little bit more."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"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)."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"We haven't seen ROI."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. 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. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"The price of this solution could be improved."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
 

Pricing and Cost Advice

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"We pay approximately $50,000 USD per year in licensing fees."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"As far as the licensing costs, everything is included in the license."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"The support cost per array is about $20,000 a year for 24/7 support."
"The licensing is on a yearly basis."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"The price is very reasonable."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"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."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"The price, in general, is around $100,000, however, I know it costs more."
"Pure has been flexible with us on the pricing models."
