The system should move towards AI-driven optimization and enhance S3 object storage capabilities.
System downtime can disturb the entire ecosystem and impact all applications.
 

Setup Cost

Pure Storage FlashBlade is costlier but valued for performance, ease, and reliability, justifying its comprehensive licensing with included software.
DataCore SANsymphony offers good price-performance, but high licensing costs and additional hardware impact overall cost-efficiency.
Nutanix Unified Storage offers competitive pricing, valued for performance and flexibility, but can be costly for smaller businesses.
The pricing of Pure Storage FlashBlade is expensive compared to other products I used from other companies in the past, but one benefit is that they have built-in ransomware protection.
The cost changed from a perpetual license to a subscription model.
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.

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.
OliverPalz - PeerSpot reviewer
Provides efficient synchronous mirroring capability and dynamic data management functionality
The initial setup is relatively easy but requires a certified DataCore implementation engineer to deploy the solution in a production environment. The deployment following the qualified procedure, typically takes about a week, depending on the amount of storage and the specific environment. With my experience, I can set up the system within two to four hours; however, the qualification process, which includes detailed planning and testing, adds additional time. It involves gathering the customer's requirements, preparing comprehensive documentation for validation, and conducting tests in collaboration with the customer. This documentation includes a site planning checklist, a pre-installation checklist, and a functional test plan to ensure everything is in order before deployment. Overall, I rate the process an eight.
Vipin Kumar Sha - PeerSpot reviewer
Pricing challenges overshadow efficient data handling and fast deployment
In terms of improvement areas for Nutanix Unified Storage (NUS), pricing is a significant issue, and another aspect is that the export of Nutanix backups does not support CD-ROMs, which is a disadvantage. Currently, it only supports QZ bus types for backups, which limits compatibility. When comparing Nutanix Unified Storage (NUS) with other solutions in the market, it falls short because it only supports iSCSI backups, while competitors also support QZ, iSCSI, fiber channel, and NVMe storage. The solution requires no maintenance for patching since it is designed effectively, but Nutanix Unified Storage (NUS) does not support fiber channel connectivity or external attached storage through NAS, limiting its compatibility. Additionally, technical support response time and efficiency are lacking in comparison to competitors.
