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.
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.

Hybrid data migration has reduced costs and now needs stronger security and database integration
I would like to share something that I believe could improve Zadara's process, which is the issue of communication with databases. Today we have MongoDB as a cloud service, so integration with databases in Zadara would bring better performance in connection in SaaS models and in dynamic models that could bring a platform and a solution that could increase Zadara's usage in the market and in its business scope. Zadara can improve in the database integration area as I mentioned. Zadara can have better dynamism such as MongoDB in SaaS and bring this better dynamism by connecting and offering it within the clouds as a possibility of block storage within that partner cloud, such as AWS EBS, Google's cloud storage, or something within Azure. Creating a stronger partnership where this block storage can become an API connectable across various clouds but native to those clouds would be beneficial. I noticed simplicity in the security part during the time I used Zadara, so I believe Zadara's security needs to improve to provide more and deliver more security visibility to the end customer so that they feel more secure with data encryption and attack protection. A WAF on the API connection that goes through greater protection, something along those lines, could help guarantee that the data is protected by Zadara.
