MikaelHellström - PeerSpot reviewer
IT Manager at Regin Dalarna
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.
Sergio Itikawa - PeerSpot reviewer
Software Solutions Architect at SPEData
Has improved data reliability while requiring better pricing and localized support
The most valuable features of Arcserve OneXafe are improving persistent data, which I believe is very important. I use other products too, not only Arcserve OneXafe; we use TrueNAS as well. I have utilized Arcserve OneXafe's data deduplication feature. It helps my storage efficiency significantly. The product satisfaction with this product helps with storage efficiency. Regarding Arcserve OneXafe's immutable object storage helping against ransomware, the call was not clear, and I had difficulty listening to what was discussed. Arcserve OneXafe improves precision of data. I have used Arcserve OneXafe's continuous data protection. This is beneficial for operational continuity because we use it constantly. I have no objections to Arcserve OneXafe technology; I think that is very good.
Amarnath Charugundla - PeerSpot reviewer
System Engineer at Tata Consultancy
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

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"The product is scalable and easy to expand."
"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."
"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 onboarding and integrated monitoring tools are pretty good."
"Using this solution has made our backups more reliable."
"Speed and ease of use are the two most valuable features."
"The simplicity and the ability to perform small backups are the most effective features for data protection in Arcserve OneXafe."
"The most valuable features of Arcserve OneXafe are improving persistent data, which I believe is very important, and I have utilized Arcserve OneXafe's data deduplication feature, which helps my storage efficiency significantly."
"The simplicity and the ability to perform small backups are the most effective features for data protection in Arcserve OneXafe."
"I rate Nutanix Unified Storage (NUS) a ten out of ten."
"The management interface is great and you have handy access to several details about your file shares."
"I rate the overall solution ten out of ten."
"I would rate Nutanix Unified Storage (NUS) a ten out of ten."
"We transitioned from a three-tier architecture to Nutanix Unified Storage (NUS). With the Files offering out of Nutanix Unified Storage (NUS), we were able to migrate those shares with a smaller footprint."
"What I found to be the most valuable features were better performance and uptime."
"The most valuable features of the solution are high availability and synchronization to another location."
"The simplicity of management is valuable because, in more traditional environments, the platform updates are much more complex."
 

Cons

"I would like to see better integration."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"I would like to see more deduplication."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"I have not seen ROI."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"Arcserve OneXafe is not used in many cases in the market that we work in."
"The price is not the best; it is too high."
"The price is not the best; it is too high. It's not the best solution in terms of price, although the solution itself is good."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."
"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."
"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp."
"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."
"The product needs to work a bit more on its ransomware detection capabilities."
"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."
"There are some techniques that need to be improved because sometimes, during processes, it gets stuck on the console, requiring command line interventions, indicating gaps between the GUI and command lines."
 

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."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"I feel that the price could always be lowered."
"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."
"Our customers have seen a reduction in TCO."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
Information not available
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"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."
"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."
"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."
"The price of the license is expensive when comparing it to traditional storage."
"The pricing is fair."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"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."
