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.

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.

Pros

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

"Everything works well, and it is very fast."

"Using this solution has benefitted us operationally by making us more efficient."

"Speed has definitely been a big improvement for us; we were running a bunch of iSCSI to EMC VNX and that had a gigabyte bottleneck, and now, since we're running through a true fiber channel to the Pure array, we're getting 32-gigabyte bandwidth, which means the speed and accessibility for our users and our customers have definitely improved."

"The most valuable feature of this solution is its ease of use."

More Nutanix Unified Storage (NUS) pros

Cons

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"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."

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

"The tool's portfolio is minimal. It is expensive."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"I'd like to see the product implement active replication for vehicles such as VMware."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

More Everpure FlashArray X NVMe cons

"The pricing should be more competitive."

"The solution's compression needs to be improved, as it's not the best."

"The ZIO interface could be improved."

"The solution's compression feature could be better."

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."

"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."

More IBM FlashSystem 9100 NVMe cons

"There should be more automation."

"Perhaps when it comes to deploying NUS virtual machines on top of CVMs, it should not be necessary for it to be in all of them or they should require fewer resources on the servers."

"Nutanix needs to improve their cybersecurity options at the storage level."

"There are still some gaps in the solution's synchronization that could be improved."

"In summary for improvements, I would say stay on the integration path, keep those integrations heavy, and let us use the software and technologies with everybody."

"It's still pretty expensive."

"The interface could be improved."

"For me, personally, it's a little bit slow because there's so much stuff in the underlying layers that even after talking with Nutanix support, I couldn't really grasp 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."

More Everpure FlashArray X NVMe pricing and cost advice

"The tool's pricing is competitive."

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"Compared to its competitors, IBM's offering is the most cost-effective."

"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."

More IBM FlashSystem 9100 NVMe pricing and cost advice

"In my opinion, the product is fairly priced."

"I'm happy with the cost and licensing because I don't have big volumes."

"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."

"Nutanix Unified Storage was cheaper than other solutions we evaluated."

"The solution's pricing is fair."

"My company is in Brazil, and making the payments in dollars is tough for our organization."

"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."

"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."
