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.

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:

"We have seen a reduction in the total cost of ownership by around 20%."
"The onboarding and integrated monitoring tools are pretty good."

"It's very easy-to-use."
"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"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."
"The simplicity and the ability to perform small backups are the most effective features for data protection in Arcserve OneXafe."
"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."
"Since migrating to Nutanix, we have not lost any data despite node failures due to its high availability and redundancy factor."
"What I appreciate most about Nutanix Unified Storage (NUS) is its user-friendly nature."
"The reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."
"The most valuable features are the interface and support."
"DR and the replication power are valuable."
"Nutanix Unified Storage (NUS) has definitely helped reduce our total cost of ownership, as centralizing that storage allowed us to eliminate all the other players we had on our premises and NASes, bringing everything under one roof."
"The biggest return on investment for me when using Nutanix Unified Storage (NUS) is the management aspect since it's easier to manage."
 

Cons

"The features provided for SMB customers are limited."
"I would like to see the licensing fees improved as well as the price per terabytes."
"There could be improvements in public cloud integration."
"The solution is expensive."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"I would also like to see better support for CIFS workloads."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"I would like to see more deduplication."
"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."
"The pricing could be improved."
"The problem is that we need to invest a lot of money to get AI, and therefore, we are not going to purchase AI right now."
"Improvement is needed regarding clarification to customers about storage capacity. While 100% storage is allocated, customers can only access 70 to 80% when examining deeply."
"A more consistent flow of information would improve the solution, as I've noticed some inconsistencies, mostly stemming from the coordination between the hardware vendor and Nutanix."
"The solution should keep adding new features to be competitive in the market."
"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."
"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."
"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."
 

Pricing and Cost Advice

"Licensing fees are paid yearly."
"The price is a little high."
"I rate the tool's pricing a seven to eight out of ten."
"The product is very expensive."
"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."
"The price of this solution could be made more affordable."
"We used a reseller for the purchase."
Information not available
"The solution's pricing is better compared to other products."
"The product is pricey."
"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."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"It is not too high for what we are using."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"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."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
