IT Manager at Regin Dalarna

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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.

Good performance and reliable but the setup is complex

We would like to see a self-sufficient installation. Nowadays it's open-source, but the installation is still tied to the vendor, which means it is unlikely that it is going to scale. I want them to tap into the broader community. It is really emerging, they have a year over year, 50% annual growth. With a 10-year-old company, it will certainly bring a lot of interest, and will certainly make it more successful, if they tap into that growing customer base. They have to make themselves relevant to the industry. The industry is totally geared to the Cloud, DevOps, and geared for agility. The software with the appliance in my set is already outdated, and it is not that it cannot sell, but it has to be tapping into the emerging and growing sectors to continue with the customers and businesses. This is what the requirement is, to improve their technology. Which means that they have to make themselves relevant to the industry.

Quotes from Members

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

Pros

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"We have seen a reduction in the total cost of ownership by around 20%."

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

"It is very easy to use, and it is very fast."

"The product is scalable and easy to expand."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"The main feature I have found to be product replication."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

More Pure Storage FlashBlade pros

"The interface is quite simple. It is very good. It is easy to configure. It also has a powerful CLI."

"The most valuable feature is that it is highly available, solving the pain-point of delaying updates to Windows-based file servers during production hours. And then the second one would be ransomware protection and analytics. It gives you great visibility and protection on your file shares that are otherwise the most common sources of vulnerabilities."

"The best Nutanix Unified Storage features are its recovery and data speeds. It has resolved the issue of accessing information quickly."

"We transitioned from a three-tier architecture to Nutanix Unified Storage (NUS). With the Files offering out of Nutanix Unified Storage (NUS), we were able to migrate those shares with a smaller footprint."

"The performance has been very good."

"Since migrating to Nutanix, we have not lost any data despite node failures due to its high availability and redundancy factor."

"We had three racks full of storage and now it is just half a rack."

"The inclusion of it in the Nutanix Objects Storage platform simplifies my process as I am no longer required to acquire a separate platform. Instead, I can simply purchase additional licenses as needed. All management can be performed from a single unified interface, making it a convenient and streamlined experience."

More Nutanix Unified Storage (NUS) pros

"The technology is stable which is good."

"Workflow is easy to manage and maintain."

Cons

"I want efficiency. FlashBlade doesn't have efficiency now."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

"The features provided for SMB customers are limited."

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

"The solution is expensive."

"The speed could be improved."

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."

"Managing other storage infrastructure on Nutanix Files Storage is an area for improvement. In particular, I want to add other forms of storage from different vendors not currently in Nutanix Files Storage, to the file server, for better management."

"The solution should keep adding new features to be competitive in the market."

"Historically, it has been a hyper-converged infrastructure, so when you are looking to grow the solution, you need to scale the compute and storage. Having the ability to scale the storage independently would be a good improvement."

"If they can add an integrated DLP feature, it would be great."

"The product does not offer one console."

"Nutanix could improve the ability to track user actions, such as identifying who deleted a folder."

"The interface could be improved."

More Nutanix Unified Storage (NUS) cons

"Lacks some ability to integrate with different systems."

"We would like to see a self-sufficient installation."

Pricing and Cost Advice

"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."

"The price is a little high."

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

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

"The pricing for FlashBlade is between cheap and moderate."

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

"Our licensing is renewed annually."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."

"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."

"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."

"Nutanix Unified Storage isn't expensive."

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

"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."

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