Room For Improvement

Users want better cloud integration, support, pricing, efficiency, and improvements in analytics, configuration, and backup for FlashBlade.
Nutanix Cloud Infrastructure needs improvements in cost, performance, integration, backup solutions, and simplifying licensing, installation, and GUI.
Nutanix Unified Storage users seek improved interface, protocol support, pricing, vendor integration, security, support, scalability, and management features.
Its configuration should be easier.
We hope Nutanix can integrate inside our current license module.
I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.
The main concern is pricing, which could deter some customers; addressing this would enhance its appeal.
The system should move towards AI-driven optimization and enhance S3 object storage capabilities.
Nutanix could improve the ability to track user actions, such as identifying who deleted a folder.
 

Setup Cost

Pure Storage FlashBlade is costlier but valued for performance, ease, and reliability, justifying its comprehensive licensing with included software.
Nutanix Cloud Infrastructure offers competitive pricing with favorable total cost of ownership, valued for its integrated solutions and features.
Nutanix Unified Storage is feature-rich and cost-effective for enterprises, with flexible pricing despite initial high expenses.
The pricing is renewed every year, at almost $100,000 per year.
It costs more compared to VMware due to different licensing areas.
Compared to buying three or four vendor solutions, it is much cheaper.
The cost has doubled for the same amount of data, which was a challenge when presenting use case justifications for the increased cost.
Nutanix Unified Storage (NUS) has definitely helped reduce our total cost of ownership.
 

Valuable Features

Featured Reviews

Eric Black - PeerSpot reviewer
The ability to leverage multi-tenancy along with immutability is a huge benefit for us
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. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.
Andrea Beccia - PeerSpot reviewer
Offers satisfying data protection and workload movement features with exceptional stability
Nutanix Cloud Infrastructure can be used up to 100% of its capacity, but our company is presently using 80% of the solution's resources. Our company manufactures iron casting products in the metal industry, and Nutanix Cloud Infrastructure is also used. For virtualization purposes, Nutanix Acropolis is used as a full-stack solution. For the Windows virtual machines in our company's server, Nutanix Acropolis is utilized instead of solutions like VMware Hypervisor. One of the main reasons our company adopted Nutanix Cloud Infrastructure was its data protection features. The solution is also used in disaster recovery through the automatic snapshots feature on the local site. Next year, our organization will try to join clusters in the network using the solution. Network clustering will help our organization's team move workloads into the geographical cluster automatically. Nutanix Cloud Infrastructure is considered an ideal solution for disaster recovery where data protection remains embedded. The solution is capable of even capturing auto snapshots for remote sites. Next year, our company plans to test new features of Nutanix Cloud Infrastructure that will assist in automated workload movements on two sides at a distance of 60 kilometers. I would recommend others use the solution for its exceptional stability, performance, hardware compatibility, and overall flexibility. Nutanix Cloud Infrastructure allows the use of varying hardware for the same cluster. I would rate the solution a nine out of ten overall.
Vishnu Mohan - PeerSpot reviewer
Centralized management and high resiliency streamline data storage with immediate benefits and scalability
The most effective features of Nutanix Unified Storage (NUS) for us are about making multiple copies of our data across hardware nodes, ensuring that if there is a hardware failure, we still don't lose our data, which I think is the most important. Also, they have a file solution that is good for file shares, and that is of value to us. The switch from solutions such as IBM to Nutanix Unified Storage (NUS) was driven by the need for different skill sets for a separate storage team and separate compute team. Maintaining these old devices was getting prohibitively high, so consolidating everything onto Nutanix Unified Storage (NUS) made sense and allowed one set of Nutanix engineers to manage the entire estate.

Originally posted at www.storagegaga.com/dont-get-too-drunk-on-hyper-converged/ I hate the fact that I am bursting the big bubble brewing about Hyper Convergence (HC). I urge all to look past the hot air and hype frenzy that are going on, because in the end, the HC platforms have to be aligned…
