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.

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.

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.

Pros

"It has benefited my organization because it has reduced time to insights."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"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."

"It has good, reliable, fast storage."

"It has benefited my organization because it has reduced time to insights."

"The solution uses newer technology for deduplication and compression."

"The solution is very straightforward to set up."

More Everpure FlashArray X NVMe pros

"I appreciate its storage licensing model, as it offers flexibility."

"The migration from VMware to Nutanix Unified Storage (NUS) is less complex and less troublesome, and the replication and clustering are very good."

"It is a highly scalable solution."

"We have been able to save local disk space by using Data Lens. We upload 18 GB to the cloud and are able to save 20% to 25%."

"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."

More Nutanix Unified Storage (NUS) pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

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

More Everpure FlashArray X NVMe cons

"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."

"The graphical user interface could provide more detail. It would be nice if we could click on the service and get some expanded definitions of them. When hiring new people, it's difficult to teach them how everything works, but if they can access everything, they can teach themselves."

"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."

"The interface is not logical. It should be a little simpler."

"Areas for improvement in Nutanix Unified Storage (NUS) include more redundancy to ensure no data loss, and balancing the workloads is very important to maintain managed workloads throughout the year."

"I would like to see the integration of artificial intelligence and machine learning technologies. That could definitely be a major breakthrough in providing a unified, seamless experience for end-users. It could reduce costs as well as human effort."

"Unified Storage failed to fulfill our object storage requirements."

"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."

More Nutanix Unified Storage (NUS) cons

"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

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

"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."

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

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

"The support cost per array is about $20,000 a year for 24/7 support."

"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."

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

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"The product has an annual licensing fee."

"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."

"In the manufacturing industry, we operate under very lean principles where costs are heavily scrutinized. There was some initial hesitation, but the performance we've experienced since switching to the Nutanix platform, along with the peace of mind from having confidence in our platform to not give us issues that keep us up at night, has smoothed over much of that scrutiny."

"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."

"The solution's pricing is better compared to other products."

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

"The product is pricey."

"Nutanix is very competitive."
