Featured Reviews

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 snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"It's very easy-to-use."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"I would rate Pure Storage FlashBlade a ten out of ten."

"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

"The Nutanix block files are the most valuable feature."

"The pricing, setup costs, and licensing of Nutanix Unified Storage (NUS) are amazing, in my view."

"What I appreciate most about Nutanix Unified Storage (NUS) is its user-friendly nature."

"It is very scalable."

"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."

"DR and the replication power are valuable."

"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."

"Nutanix support deserves a rating of nine out of ten."

More Nutanix Unified Storage (NUS) pros

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

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

Cons

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"There could be improvements in public cloud integration."

"I have not seen ROI."

"I would like to see more deduplication."

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

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"The GUI is easy to use, but it's complex to do tasks from the command line. That is one way they could simplify things for the engineers. People tend to use a graphical interface more than the command line interface. If anything goes wrong, we need to do troubleshooting from the CLI. It would be nice if there were more ways to fix issues within the GUI."

"The escalation process with technical support could do with some improvement."

"Pain points are just in the management and understanding of how the functions work."

"Customer service is more difficult to call and they do not responding as much as, for example, DataCore. It's not the same level of satisfaction compared to DataCore. Responses could be faster."

"For P1 and P2 alerts in the Nutanix Unified Storage (NUS) file share system, including SMB, NFS, objects, or blocks, we must maintain vigilant monitoring. This is crucial because system downtime can disturb the entire ecosystem and impact all applications."

"The graphical user interface could provide more detail. It would be nice if we could click on the service and get some expanded definitions of them. When hiring new people, it's difficult to teach them how everything works, but if they can access everything, they can teach themselves."

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

"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."

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

"The price is a little high."

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

"I rate the tool's pricing a seven to eight out of ten."

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

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"Licensing fees are paid yearly."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

More Pure Storage FlashBlade pricing and cost advice

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

"Nutanix Unified Storage pricing is reasonable."

"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."

"The solution’s pricing could be cheaper."

"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."

"In the manufacturing industry, we operate under very lean principles where costs are heavily scrutinized. There was some initial hesitation, but the performance we've experienced since switching to the Nutanix platform, along with the peace of mind from having confidence in our platform to not give us issues that keep us up at night, has smoothed over much of that scrutiny."

"The product is pricey."

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

More Nutanix Unified Storage (NUS) pricing and cost advice

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

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