Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

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

"The database workloads are pretty fast because I frequently move data from here to there."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"Technical support has been helpful and responsive."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

More Pure FlashArray X NVMe pros

"The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."

"The technical support for this solution is good. They used to help us when the motherboard of Power Systems broke. Their response times are really fast."

"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."

"It's a mature product. It's like a BMW that evolves consistently."

"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."

"IBM FlashSystem is flexible, quick, and has a solid design."

"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."

"It's very easy to manage."

More IBM FlashSystem pros

"The main advantage of this solution is performance."

"It provides multi-protocol, which is what gives the edge when it comes to big lineage PC workloads."

"The most valuable feature of this solution is its speed."

"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."

"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."

"Compared to Dell Unity XT, what I see as an advantage in NetApp EF-Series All Flash Arrays is the fact that it is more scalable...The performance of the product is good."

"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."

"The stability, speed, and reliability are the solution's best features. The information is also very secure."

Cons

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"It is on the expensive side."

"I would like to see replication and DR features in the next release of this solution."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"There are some challenges with data encryption and reduction."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"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."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

More Pure FlashArray X NVMe cons

"We had issues when attempting to do a flash, we hope to resolve it soon."

"It is slightly more expensive, however, it all depends on your supplier."

"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."

"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."

"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."

"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."

"There could be some extra features added."

"The pricing needs to be more competitive."

More IBM FlashSystem cons

"This solution has limited storage."

"NetApp could improve the speed of the rebuilding rate."

"This solution does not have any compression or deduplication."

"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"

"There could be an improvement when it comes to SLA support, it could be faster."

"The support of the product is an area with certain shortcomings where improvements are required."

"The management interface, while very reliable, it seems a little old now and could maybe use a little modernization."

"The initial setup phase of NetApp EF-Series All Flash Arrays is not straightforward and needs improvement."

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"Our licensing fees are $500,000+ USD."

"As far as the licensing costs, everything is included in the license."

"With VMware, we pay $300,000 annually."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"We pay approximately $50,000 USD per year in licensing fees."

"The licensing is on a yearly basis."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

More Pure FlashArray X NVMe pricing and cost advice

"Our customers would like IMB FlashSystem to be less expensive."

"This is an expensive product and if the price were reduced it would be better."

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."

"The solution requires a license and could be less expensive."

"They've been much more aggressive in the last five, six years than they were before that."

"The price is a little bit high so is rated a six out of ten."

"I find the pricing of the solution to be very reasonable."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

More IBM FlashSystem pricing and cost advice

"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."

"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."

"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."

"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."

"NetApp EF-Series All Flash Arrays is an expensive product."

"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."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"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."
