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

"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."
"The onboarding and integrated monitoring tools are pretty good."
"It helps simplify our storage, because the user interface is very simple and the installation is easy."
"The most valuable features of this solution are the rewrite speed and the nonstop services."
"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."
"The most valuable feature of this solution is performance."
"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."
"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."
"The most valuable feature is the storage density of the nodes. We went with the HP's low-density nodes."
"My experience with using Nutanix Unified Storage (NUS) for data-intensive workloads is that we have many SQL Servers and they perform much better than they did when we used hybrid converged previously."
"The interface is quite simple. It is very good. It is easy to configure. It also has a powerful CLI."
"The aspect of the product that I like the most is its simplicity."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"We have been able to save local disk space by using Data Lens. We upload 18 GB to the cloud and are able to save 20% to 25%."
"The reliability and stability of Nutanix Unified Storage (NUS) is good, and the disaster recovery component is something impressive for this product."
"I strongly recommend Nutanix Unified Storage (NUS) to all users as a modern cloud computing system, offering significant cost savings for clients, customers, and vendors while providing excellent cloud infrastructure operations."
"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

"It would be nice if you could store file-based in the same box with the same technology."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."
"I would also like to see better support for CIFS workloads."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"I would like to see more deduplication."
"Its configuration should be easier."
"I would like to see more VM-Aware features in the next release of this solution."
"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"The dashboard could be more customizable"
"One thing I'd appreciate is having a desktop application similar to what VMware offered."
"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."
"The interface is not logical. It should be a little simpler."
"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."
"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."
"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

"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."
"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."
"The price is a little high."
"I understand that it is competitively priced compared to other brands."
"Our licensing is renewed annually."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"I rate the tool's pricing a seven to eight out of ten."
"The pricing for FlashBlade is between cheap and moderate."
"The pricing is a bit too high."
"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."
"It is very good. It is much more competitive than a dedicated storage platform."
"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."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
