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.

Runs smoothly and provides excellent performance and throughput
I love the SnapMirror and autonomous ransomware protection features. SnapMirror is used for replication purposes in a DC/DR setup. If something goes wrong with the data center or production DR, the data automatically gets replicated to the DR site, and the DR site becomes operational, allowing continued access to data. Autonomous ransomware protection helps recover data in case of any threat or ransomware. Ransomware is increasing daily, and according to Gartner, most companies have to pay a ransom if a ransomware attack occurs in their environment. NetApp provides a ransomware guarantee program where they commit that if data cannot be recovered in case of ransomware, NetApp will provide compensation, which adds significant value.
Amarnath Charugundla - PeerSpot reviewer
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

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The high availability of the product is the most valuable feature."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"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 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."
"I love the SnapMirror and autonomous ransomware protection features."
"I love the SnapMirror and autonomous ransomware protection features."
"Their dedupe functionality is probably the best in the industry. We also find their support model to be good. When we purchase something, we have a very good understanding of how long that product will be supported by them. That helps."
"The product's benefits stem from the ease of use and management it offers to its users."
"Customer support for Nutanix Unified Storage (NUS) is top-notch."
"I would rate Nutanix Unified Storage a ten out of ten."
"The most important point is the simplicity of the API integration. We can leverage the API integrations and connect our hybrid-cloud network environment with Nutanix's cloud storage."
"What I appreciate most about Nutanix Unified Storage (NUS) is its user-friendly nature."
"The solution is stable and extremely easy to calibrate."
"Nutanix Volumes is a perfectly stable product."
"The solution is easy to use, share, and manage."
 

Cons

"We need better data deduplication."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"The tool's pricing is higher than competitors."
"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"I would like to see more in terms of replication between storage classes. They provide different lines of storage. They have a lower class. They have a capacity class. They have their enterprise class. Currently, we have interoperability at the same plane with ONTAP, but we would like to see some more mix-and-match features."
"I'm handling pre-sales and post-sales. From a partner's point of view, the tools that I'm using to create the quote or do the sizing are very slow. The tools, such as hardware universe, fusion.netapp.com, and partnerhub.netapp.com, operate very slowly. These tools should be more efficient as they enter a hung state repeatedly."
"From a partner's point of view, the tools that I'm using to create the quote or do the sizing are very slow."
"There should be more automation."
"Pain points are just in the management and understanding of how the functions work."
"When it comes to Nutanix Files, one thing that would be great is a slightly easier way of managing snapshots and restore points, especially when a third party is involved."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."
"Historically, it has been a hyper-converged infrastructure, so when you are looking to grow the solution, you need to scale the compute and storage. Having the ability to scale the storage independently would be a good improvement."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
"I would them to have more communication with other platforms, and it appears they are already doing that."
 

Pricing and Cost Advice

"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 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."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The licensing is on a yearly basis."
"Given its price, Pure is not the first option."
"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."
"The product is expensive."
"It's more expensive than other storage vendors such as Dell, Pure Storage, HPE, Lenovo, etc. It provides the value, but some of the customers don't look at the value. They first look at the cost. It should be reduced by 20% to 30%."
"It is pretty good. It is definitely cheaper than Dell EMC. It is cheaper than Pure. It is cheaper than VAST. It is definitely cheaper than HPE. The only one that is on par with NetApp's pricing for enterprise customers is IBM."
"The solution is highly-priced."
"The pricing is a bit too high."
"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"The product is pricey."
"It is not too high for what we are using."
"The product has an annual licensing fee."
