Enables seamless file distribution while benefiting from scalability but could use simplified implementation
IBM Storage Fusion is used in telecoms. It is a file center that receives and shares files. It is also used for writing the CDR zone on the storage, since it offers a cost-effective solution for large-scale storage needs in a telecom setup The deployment of Storage Fusion has been new for us in…

Ensures streamlined management, simplified infrastructure, and efficient data handling
It has effectively managed our unstructured data, including audio and video files. We've experienced smooth operations without any complaints regarding uploading or downloading videos. While video usage isn't as frequent, we primarily utilize it for downloading videos related to specific incidents for administrators or our police department. We've encountered no issues uploading files of any kind. Transitioning from VMware to Nutanix has highlighted the overall flexibility of Nutanix's platform. Unlike VMware's three-tier system, Nutanix simplifies the learning curve by streamlining operations. The update process, in particular, has been favorable, with no critical issues encountered. The resiliency of Nutanix hasn't been thoroughly tested in our environment so far. However, I routinely check fault tolerance settings to ensure they meet our requirements. During the update process, I've observed critical errors occur as hosts restart, but Nutanix's self-healing mechanism handles these issues seamlessly. The benefit of using Nutanix is evident in several ways. Firstly, we've effectively compressed our storage while significantly expanding our overall storage pool. Previously, our service had a capacity of twenty-five terabytes, but with Nutanix, we've scaled up to a hundred and twenty terabytes physically and approximately fifty terabytes logically. This expansion has been accompanied by noticeable improvements in performance, particularly with reduced latency and IOPS well within the boundaries of our equipment. All our resources are centralized in a single location for managing and running storage: our data center. We operate three Nutanix nodes within this center, effectively managing everything from one central location. We don't have any other locations outside of our data center running a Nutanix cluster. Nutanix's capability to eliminate silos within our organization's storage infrastructure was discussed during our recent call with the engineer. Although we haven't explored this feature extensively yet, there's a forthcoming project where we anticipate leveraging it.One thing I'd appreciate is having a desktop application similar to what VMware offered. With VMware, I could download a separate client program onto my computer, allowing me to log in directly rather than accessing the host through a browser.

Quotes from Members

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

Pros

"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."
"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 product's benefits stem from the ease of use and management it offers to its users."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"It gives more security that the data isn't going to get lost."
"The solution's most valuable feature is the Prism Central centralized management console."
"I appreciate its storage licensing model, as it offers flexibility."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"I like its interface. It is very interactive and simple to use."
 

Cons

"The implementation is complex, especially when using custom servers."
"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
"Unified Storage failed to fulfill our object storage requirements."
"Lowering the price would improve this product."
"The management is pretty clunky, in my opinion. It could be a little bit better."
"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."
"The pricing could be improved."
"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."
 

Pricing and Cost Advice

Information not available
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"The solution's pricing is fair."
"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"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 Unified Storage was cheaper than other solutions we evaluated."
"Nutanix Unified Storage pricing is reasonable."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
