Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Offers good features like Fusion and stable product with better customer service
Fusion is the only best feature, but it's a very good feature. Nexenta is a very old product. Nexenta is a well-established product used in the UK, US, India, Dubai, Qatar, and other countries. It is very good. The interface is up to date. Everything is up to date. The OS version was recently upgraded to 5.5 FP3. AI features: DataDirect Networks owns Nexenta and has won awards for AI. They continuously work on AI features. DDN also has a product called Tintri Infinia with AI features. And NVIDIA product also has AI features. I look forward to working on those products.

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

"We can capacity plan at a greater level than we used to."
"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"The onboarding and integrated monitoring tools are pretty good."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"The initial setup is pretty quick."
"The main feature I have found to be product replication."
"It has a feature called Fusion that makes it more secure and productive."
"On a scale of one to ten, I rate this solution a seven."
"The scalability, data redundancy, and security are valuable."
"What I appreciate about Nutanix Unified Storage (NUS) is that we have faced several issues in the Unified Storage, the compression and deduplication features have worked exceptionally well in the Unified Storage, and it has helped my business as it operates seamlessly without any interruption."
"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."
"We have seen reduced overheads and increased efficiency with Nutanix Unified Storage (NUS)."
"Nutanix Unified Storage (NUS) is very fast in terms of migration and data access with respect to VM, OS, and storage, experiencing a 30% faster performance compared to VMware."
"The product's benefits stem from the ease of use and management it offers to its users."
"The solution is stable and extremely easy to calibrate."
 

Cons

"The feature that we're waiting on is better integration with the cell services."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."
"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."
"Pure Storage FlashBlade should improve on more cloud integration."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"There were some SMB issues, but they were resolved."
"There are still some gaps in the solution's synchronization that could be improved."
"Pain points are just in the management and understanding of how the functions work. As far as updating and day-to-day operations, if my staff is properly trained and we have those proper training sessions, we don't have that many issues. There can be more educational resources from their side."
"Nutanix Unified Storage (NUS) can be improved involve the limitations I've seen in Files Analytics, specifically to the number of FSVMs today that File Analytics can analyze."
"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."
"The solution should increase its storage capabilities."
"Nutanix Unified Storage (NUS) can be improved in the area of big data workloads, as we still need to improve performance there."
"The dashboard can have more details and be more useful."
"The solution should keep adding new features to be competitive in the market."
 

Pricing and Cost Advice

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"I rate the tool's pricing a seven to eight out of ten."
"We used a reseller for the purchase."
"The price could be cheaper."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"I feel that the price could always be lowered."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I understand that it is competitively priced compared to other brands."
Information not available
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"The solution is highly-priced."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"The price of the license is expensive when comparing it to traditional storage."
"The solution's pricing is better compared to other products."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"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."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
