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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

System Engineer at Tata Consultancy

Unified management and cost-effectiveness lead to positive experiences and future savings

Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

Quotes from Members

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

Pros

"The latency is good."

"The solution is scalable."

"The most valuable features of this solution are its ease of use and performance."

"It has good, reliable, fast storage."

"The initial setup was extremely simple and straightforward."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"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."

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

More Pure FlashArray X NVMe pros

"The initial setup is straightforward."

"We use IntelliFlash products for larger environments, like Qatar Airways."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"Data Compression: Up to 80% space reduction in the database"

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"High performance and ease-of-management are the most valuable features."

"It performed great originally, and when it performed great, it was awesome."

More DDN IntelliFlash pros

"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."

"The management interface is great and you have handy access to several details about your file shares."

"The solution is very easy to manage."

"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."

"Management-wise, it has made work a lot easier. It is all in one place physically. It is much better now."

"The product's initial setup phase was simple."

"Nutanix Unified Storage is very stable."

"The best Nutanix Unified Storage features are its recovery and data speeds. It has resolved the issue of accessing information quickly."

More Nutanix Unified Storage (NUS) pros

Cons

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"In the future, I would like to see integration with enterprise backup systems."

"The tool's pricing is higher than competitors."

"It is on the expensive side."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"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."

More Pure FlashArray X NVMe cons

"It's somewhat scalable, but maybe not so much as some of the competition."

"Snapshots are not as easy to access as on a NetApp device."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"In future releases, I look forward to more AI features."

More DDN IntelliFlash cons

"Since it's part of Prism, I might suggest integrating the management console into Prism instead of having a separate console; that's the only change I would recommend, and it's not a significant issue."

"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."

"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."

"The product does not offer one console."

"The pricing can be quite high."

"Nutanix Unified Storage (NUS) can be improved involve the limitations I've seen in Files Analytics, specifically to the number of FSVMs today that File Analytics can analyze."

"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."

"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"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."

"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."

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

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

"Given its price, Pure is not the first option."

"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 tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."

"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."

"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."

"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."

"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."

"The solution is highly-priced."

"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."

"The pricing is fair."
