Eric Black

Solutions Architect at Recovery Point Systems

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

System Engineer at Tata Consultancy

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.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

More Pure Storage FlashBlade cons

"Areas for improvement in Nutanix Unified Storage (NUS) include more redundancy to ensure no data loss, and balancing the workloads is very important to maintain managed workloads throughout the year."

"I would not recommend Nutanix Unified Storage (NUS) to other users or developers because it does not support fiber channel (FC) or NVMe storage, and only supports iSCSI, which I believe is outdated technology in today's market."

"Improvement is needed regarding clarification to customers about storage capacity. While 100% storage is allocated, customers can only access 70 to 80% when examining deeply."

"There are still some gaps in the solution's synchronization that could be improved."

"One thing I'd appreciate is having a desktop application similar to what VMware offered."

"The solution is very expensive."

"The training programs could be improved. It's quite challenging to find adequate learning resources online, as there isn’t much available on the internet or YouTube."

"The product does not offer one console."

More Nutanix Unified Storage (NUS) cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"I understand that it is competitively priced compared to other brands."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"The price of this solution could be made more affordable."

"The price is a little high."

"The price could be cheaper."

"Our licensing is renewed annually."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"I feel that the price could always be lowered."

More Pure Storage FlashBlade pricing and cost advice

"Nutanix Unified Storage isn't expensive."

"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."

"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."

"The pricing is a bit too high."

"It is very good. It is much more competitive than a dedicated storage platform."

More Nutanix Unified Storage (NUS) pricing and cost advice
