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.

Efficient data management leads to significant cost savings through advanced inline deduplication
NetApp's inline deduplication and compression are unmatched compared to other vendors. With both deduplication and compression inline, we experience no cost in terms of performance on the systems, however, we have huge savings on the storage side. We can turn it on for everyone and save storage space, allowing us to sell more to customers. NetApp also provides us with an interface for VLAN separation that no other vendor can provide, allowing our customers distinct, separated network layers in between.

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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"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."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"I appreciate the performance."
"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."
"The solution is very straightforward to set up."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The latency is good."
"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 support is fantastic."
"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."
"The deduplication and compression options from NetApp AFF A-Series are good to use for efficient storage capacity."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"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'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 helps us get the fastest output."
"The Nutanix block files are the most valuable feature."
"The simplicity of management is valuable because, in more traditional environments, the platform updates are much more complex."
"The product is good, easy to upgrade, easy to use, and user-friendly."
"It is unified. This is the best thing that Nutanix gave to the world. You can do everything from one point."
"I would rate Nutanix Unified Storage (NUS) a ten out of ten."
"The benefit that our clients see is the security of the whole Nutanix platform where they have simplified usage."
"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."
"Nutanix Unified Storage is very stable."
 

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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"There is room for improvement in the pricing of the product."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
"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."
"The solution's ransomware protection could be improved."
"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."
"Pricing could always be lower."
"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."
"For future updates, I think Nutanix Unified Storage (NUS) should look at features similar to what ONTAP of NetApp is doing, such as tiering to the public cloud."
"From a management side, the one thing I would prefer is if it were a bit less expensive for smaller enterprises. It's a bit costly. If they provided flexible modules where you could pick and choose features, and only pay for what you use, that would be an improvement."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection. Currently, we have 30 days' worth of snapshots going back and forth for data protection. A migration tool to transition to better syncing for DR would be valuable, as otherwise, we lose 30 days because of the storage requirement."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
"There are still some gaps in the solution's synchronization that could be improved."
"The solution should increase its storage capabilities."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
"Pain points are just in the management and understanding of how the functions work. As far as updating and day-to-day operations, if my staff is properly trained and we have those proper training sessions, we don't have that many issues. There can be more educational resources from their side."
 

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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."
"The product is expensive."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"The licensing is on a yearly basis."
"With VMware, we pay $300,000 annually."
Information not available
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"It is very good. It is much more competitive than a dedicated storage platform."
"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
