Sentiment score
7.5
Users of Nutanix Unified Storage experienced reduced costs, improved efficiency, and enhanced performance with simplified management and increased data security.
Sentiment score
8.2
Zadara offers cost-effective scalability, eliminating upfront investments with flexible, nearly limitless capacity, potentially saving 50% in time and money.
It does not require much management once you set up correctly, so it saves time, allowing an admin to focus on other work.
For me, the biggest return on investment when using this solution is that we do not have to have much support staff to run it.
The scalability challenge with previous systems is lessened with Nutanix since we can expand by adding new hardware without needing migrations.
We are saving approximately 20% to 25% compared with the competition.
The cost is not cheaper compared to AWS, and we have not seen the expected return on investment.

They are very knowledgeable, and if they can't solve the problem, they find the answer within a day or so.

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.
Amarnath Charugundla - PeerSpot reviewer
Unified management and cost-effectiveness lead to positive experiences and future savings
Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.
Kirubel Behailu - PeerSpot reviewer
