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.

Gives us the foundation to grow efficiently
We're a manufacturer. All of our ERP software is dependent upon fast performance and connection to this hardware. So when there was an issue years ago when something was wrong or slow, that prompted us to say, "Can we check storage? Can we check the network?" Ever since we've gone up to all-flash FAS systems, there's never any questions about performance when it comes to storage. There's been a huge leap from spinning disks to SSDs. I'm hoping with the next update, we'll go to NVMe and we'll have similar experiences. Last year, we refreshed the SAN at our headquarters. We signed a Keystone agreement with the ability to pay for storage as a service at an excellent price point yet still have the hardware on-prem. I manage the hardware, and, for me, it's the best of both worlds. We've just come up with a situation where, finally, after some time, we're going to need to buy some additional storage. In previous situations like this, it usually meant the purchase of an additional shelf at a large price. Now we have Keystone, and we're locked in at that price per tebibyte. We just have to say that we want to add 25 tebibytes and they take care of it. It's worked out really well. We work ISO 27001 certified. Since I manage the enterprise storage, we use SnapMirror, and we're currently using Veeam for backups. Thanks to what this tool provides, we are able to get through that portion of our certification without a problem. No changes, no rectifying. It's very slick. Our company's goals include maintaining a level of consistency. We're never going to be on the bleeding edge. We're never going to have the super fastest abilities. We want something that works, is easier for us to manage, and has a better growth path. For us, in the past, in the need for additional disk space, if we didn't do the sizing right in the first place, buying additional disks was incredibly expensive. Now, with Keystone, that's no longer an issue, and that's what we like.

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"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 has good, reliable, fast storage."
"One of the best features is the support, which is excellent."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The latency is good."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"NetApp support is fantastic."
"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."
"NetApp helps us get the fastest output."
"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."
"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."
"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"In the future, I would like to see integration with enterprise backup systems."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The tool's portfolio is minimal. It is expensive."
"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."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"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."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"They could add more support for file storage and different types of storage."
"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."
"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."
"Pricing could always be lower."
"The solution's ransomware protection could be improved."
"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"The product is expensive."
"The support cost per array is about $20,000 a year for 24/7 support."
"We pay approximately $50,000 USD per year in licensing fees."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"Our licensing fees are $500,000+ USD."
