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.

HPC CTO at a manufacturing company with 10,001+ employees

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The onboarding and integrated monitoring tools are pretty good."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The solution provides many controllers."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

More Pure Storage FlashBlade pros

"Nutanix technical support is excellent, with swift responses based on priority."

"Nutanix's analytics provide better insights into all of our files."

"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."

"Whenever we have some necessity in terms of capacity and expansion of infrastructure, it's like a Lego system where they can just place in some more nodes and our needs are met."

"We appreciate how Nutanix Unified Storage (NUS) performs very well. We appreciate being able to have the duplication of the data to a secondary location."

"The features I appreciate the most about Nutanix Unified Storage (NUS) are the compatibility with the market."

"The customer service executives of all Nutanix products are active and responsive."

"The management interface is great and you have handy access to several details about your file shares."

More Nutanix Unified Storage (NUS) pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"I would like to see more deduplication."

"Pure Storage FlashBlade should improve on more cloud integration."

"There could be improvements in public cloud integration."

"I would like to see more VM-Aware features in the next release of this solution."

"The feature that we're waiting on is better integration with the cell services."

"They need better integration with public clouds along with a better hybrid solution."

"The solution is expensive."

More Pure Storage FlashBlade cons

"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."

"The solution should increase its storage capabilities."

"We couldn't access Nutanix Unified Storage (NUS) from Prism Central due to bugs. The bugs that Nutanix fixed in newer versions prevented us from accessing Nutanix Unified Storage (NUS) from Prism Central."

"It's still pretty expensive."

"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."

"For future updates, I think Nutanix Unified Storage (NUS) should look at features similar to what ONTAP of NetApp is doing, such as tiering to the public cloud."

"There should be more information. If it gets used more by more people, they will have a bigger community to share ideas. It is still kind of newer. It is not as big as Dell and other companies."

"I would them to have more communication with other platforms, and it appears they are already doing that."

More Nutanix Unified Storage (NUS) cons

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

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

Pricing and Cost Advice

"We used a reseller for the purchase."

"The price could be cheaper."

"Our customers have seen a reduction in TCO."

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

"Our licensing is renewed annually."

"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 product is very expensive."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

More Pure Storage FlashBlade pricing and cost advice

"The product has an annual licensing fee."

"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."

"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."

"It is not too high for what we are using."

"Nutanix is very competitive."

"The pricing is fair."

"Nutanix Unified Storage was cheaper than other solutions we evaluated."

"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."

More Nutanix Unified Storage (NUS) pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
