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.

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.

Quotes from Members

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

Pros

"FlashBlade offers low latency, high throughput, and seamless scalability."
"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"The most valuable feature of this solution is performance."
"It's very easy-to-use."
"It helps simplify our storage, because the user interface is very simple and the installation is easy."
"It is very easy to use, and it is very fast."
"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."
"Offers high performance, full control, and strong security for mission-critical workloads."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"The most valuable feature is that it is highly available, solving the pain-point of delaying updates to Windows-based file servers during production hours. And then the second one would be ransomware protection and analytics. It gives you great visibility and protection on your file shares that are otherwise the most common sources of vulnerabilities."
"The solution is easy to use, share, and manage."
"The access to that file storage shared folder is very good compared to other storage, and the storage access speed is very fast for Nutanix Unified Storage (NUS)."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
"One of the main features of Nutanix Unified Storage (NUS) that I find most valuable is the flexibility and scalability of it, as well as the ability to perform replication for our Disaster Recovery environment."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"I want efficiency. FlashBlade doesn't have efficiency now."
"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."
"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 is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"I would like to see better integration."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"The features provided for SMB customers are limited."
"I have not seen ROI."
"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."
"The only thing I would say is missing for us it is FTP protocol compatibility."
"Unified Storage failed to fulfill our object storage requirements."
"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."
"Nutanix needs to improve their cybersecurity options at the storage level."
"Perhaps Unified Storage could be improved by including artificial intelligence to make searches more effective. Also, if someone has access who shouldn't, it could automatically update, so I do not need to physically remove permission. The platform could do it automatically. AI could make it more self-service."
"The biggest thing for me, which is a pet peeve of mine, is the integration with the hardware platforms."
"There is potential to push this product more since it's not common in the market. They could increase their marketing efforts."
"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

"The price is a little high."
"I rate the tool's pricing a seven to eight out of ten."
"The product is very expensive."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I feel that the price could always be lowered."
"The pricing for FlashBlade is between cheap and moderate."
"Our licensing is renewed annually."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"The licensing model the tool has is cheaper than an HCI storage solution."
"The solution's pricing is better compared to other products."
"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."
"Nutanix is very competitive."
"The pricing is a bit too high."
"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
