Jaehoon Oh - PeerSpot reviewer
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.
BrijeshKumar - PeerSpot reviewer
With an easy initial setup phase, the tool is useful for multi-site replication and DR
The configuration part of the product is an area with certain shortcomings where improvements are required. If the product is up and running after, if it goes down, my company has observed that there are multiple failures that occur in the tool, so it needs to be reinstalled from scratch. The tool should have an automated feature or an automated option to handle the aforementioned scenario, which one can simply go and reset, after which the tool should be reinstalled with the same configuration.
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

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The solution is very straightforward to set up."
"The solution uses newer technology for deduplication and compression."
"Everything, especially the VMs inside, is pretty fast."
"The most valuable features of this solution are its ease of use and performance."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Technical support has been helpful and responsive."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"The most valuable features of VMAX are its performance and GUI interface."
"It works very well."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The product's initial setup phase was good."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"My company has benefitted from Nutanix Unified Storage because we have everything in a centralized place. With Prism Central, we can go to the console files and do what we have to do."
"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"The pricing, setup costs, and licensing of Nutanix Unified Storage (NUS) are amazing, in my view."
"I find that Nutanix’s resilience is the most valuable because it is a feature that is not found in other technologies."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"Nutanix Unified Storage is easy to use. New employees are able to come up to speed fairly quickly with regard to the day-to-day administration processes."
"The most valuable features are the interface and support."
 

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"The UI for this solution needs to be improved."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's pricing is higher than competitors."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"Improvements are needed in both partition recovery and scalability."
"There is room for improvement in the centralized administration."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."
"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."
"The solution should keep adding new features to be competitive in the market."
"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"Regarding areas where Nutanix Unified Storage (NUS) could improve, they should focus on pricing transparency and reducing licensing complexity."
"A more consistent flow of information would improve the solution, as I've noticed some inconsistencies, mostly stemming from the coordination between the hardware vendor and Nutanix."
"Some of the new features in the tool cannot be used with just one click, as was possible in the past."
"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."
 

Pricing and Cost Advice

"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 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."
"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."
"As far as the licensing costs, everything is included in the license."
"With VMware, we pay $300,000 annually."
"The support cost per array is about $20,000 a year for 24/7 support."
"Our licensing fees are $500,000+ USD."
"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."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"It is not a cheap product."
"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."
"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."
"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."
"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"It is very good. It is much more competitive than a dedicated storage platform."
"The solution's pricing is better compared to other products."
"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."
