Project Engineer at Astellas Pharma US
Archiving data has reduced storage costs and provides reliable long‑term retention
We have not really come across any downsides for us. It is possible that the retrieval of data may be expensive, which could be an issue, but we have not experienced that in fairness. Integration with our policies would be beneficial. We have policies for our systems where we delete data after a certain number of years, and having integration with Amazon S3 Glacier would be good. Having a guarantee that Amazon S3 Glacier would persist for the amount of time that we require in our archives would be valuable. In other words, Amazon would need to commit to support for the period we need. We could be talking about 20 years or longer. We cannot always move to the next version because we need to maintain old systems and legacy systems in order to maintain archives. A guarantee around support would be a good thing to have.
NISHANTPANCHAL - PeerSpot reviewer
Principle Technical Specialist at a comms service provider with 1,001-5,000 employees
Unified storage has simplified private cloud operations and delivers strong security and ROI
Regarding areas for improvement, I think Data Lens could be enhanced from Nutanix's side, but it has been a long time since I logged into that console, so I do not remember much. It is a SaaS-based offering on the Nutanix portal. It is not something you deploy on-premises; it is not on-prem access. You connect your cluster to the SaaS-based Nutanix and then access the Lens console. I need to check it since it has been almost two or three months since I logged in. Nutanix Enterprise AI actually needs to improve a lot if I compare it with any other product such as NVIDIA and other offerings in the market. Nutanix Enterprise AI still requires a lot of work. I did not check that in much detail technically, but whatever I thoroughly checked, it still lags behind in many features. When it comes to AI-related features, I think the ecosystem of Nutanix is not as big as NVIDIA because NVIDIA has its own inferencing system and model training platform such as NeMo, NeMoTron, and others. Nutanix does not have such things. It can be built using NVIDIA CUDA libraries, but what I saw when I was testing the product is that you can run NVIDIA NeMo and PyTorch and two other things, but as a software, Nutanix does not have an end-to-end platform. That is something Nutanix should focus on.
