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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"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."

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

"I appreciate the performance."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

More Pure FlashArray X NVMe pros

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"We have been working with the solution for around a year and so far it has shown itself to be stable."

"Its initial setup process is easy."

"Lenovo ThinkSystem DE Series is simple to use"

"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"The solution is very easy to set up."

More Lenovo ThinkSystem DE Series pros

"We have seen reduced overheads and increased efficiency with Nutanix Unified Storage (NUS)."

"Offers high performance, full control, and strong security for mission-critical workloads."

"Nutanix Volumes is a perfectly stable product."

"Nutanix support deserves a rating of nine out of ten."

"Currently, the most valuable aspect of our Nutanix implementation is its file storage functionality."

"The inclusion of it in the Nutanix Objects Storage platform simplifies my process as I am no longer required to acquire a separate platform. Instead, I can simply purchase additional licenses as needed. All management can be performed from a single unified interface, making it a convenient and streamlined experience."

"I would rate Nutanix Unified Storage (NUS) a ten out of ten."

"They have well-documented best practices and the interface is good."

More Nutanix Unified Storage (NUS) pros

Cons

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"Adding some functions to the product would be beneficial."

"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."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"There is room for improvement in the pricing of the product."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"The tool's pricing is higher than competitors."

More Pure FlashArray X NVMe cons

"The features are limited."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"The solution could be more scalable, although it suits our present needs."

"It would be useful to have structured solutions replicated to other sites."

"In the next release, I would like to see support for Hyper-converged infrastructure."

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

More Lenovo ThinkSystem DE Series cons

"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."

"The management is pretty clunky, in my opinion. It could be a little bit better."

"The graphical user interfaces could benefit from more attention to detail."

"The documentation on the support site needs to be improved."

"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."

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

"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."

"There should be more information. If it gets used more by more people, they will have a bigger community to share ideas. It is still kind of newer. It is not as big as Dell and other companies."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

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

"The licensing is on a yearly basis."

"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."

"Given its price, Pure is not the first option."

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."

"The best thing about this solution is its price, which reduces our costs."

"The pricing is fair and low compared to other products in this category."

"It is an expensive solution."

"We have a five-year contract for providing support."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"The solution's price could be better."

"The pricing for this solution is good compared to HP or Dell EMC."

More Lenovo ThinkSystem DE Series pricing and cost advice

"Nutanix Unified Storage isn't expensive."

"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."

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

"The product has an annual licensing fee."

"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."

"The solution is highly-priced."

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

"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."
