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.
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.
Kirubel Behailu - PeerSpot reviewer
