High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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

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

"Using this solution has made our backups more reliable."

"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."

"The initial setup is pretty easy and simple."

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

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

"Speed and ease of use are the two most valuable features."

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

More Pure Storage FlashBlade pros

"The most valuable feature of Nutanix Unified Storage is the ease of setting up file shares. As a global company with data centers around the world, our files clusters are accessible globally. Managing and setting up shares for our over 12,000 employees is straightforward."

"What I found to be the most valuable features were better performance and uptime."

"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."

"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."

"Management-wise, it has made work a lot easier. It is all in one place physically. It is much better now."

"The life cycle managers of the PCMs are very impressive, and I like them. They make our lives easy when managing patches and security updates when they come in. A life cycle manager helps to consolidate different vendors."

"It is unified. This is the best thing that Nutanix gave to the world. You can do everything from one point."

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

More Nutanix Unified Storage (NUS) pros

"Workflow is easy to manage and maintain."

"The technology is stable which is good."

Cons

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

"It's on the expensive side, as expected for a niche product."

"I would also like to see better support for CIFS workloads."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"I would like to see more monitoring capability included in the next release of this solution."

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

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 documentation on the support site needs to be improved."

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

"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."

"Its licensing can be better. They can make it easier for us to scale our infrastructure."

"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."

"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."

"The solution needs to be more open to integration with other vendors. Sometimes, we struggle with the support process. Our skilled engineers must explain our problems to everyone, even though we've already done preliminary investigations. The support team follows standard procedures, which can be painful. We're not a small customer, especially in the life sciences sector, so we'd appreciate more specialized support. I've heard Nutanix Unified Storage has teams dedicated to life sciences and healthcare; we should be part of that."

More Nutanix Unified Storage (NUS) cons

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

"Lacks some ability to integrate with different systems."

Pricing and Cost Advice

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

"The price is a little high."

"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 of this solution could be made more affordable."

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

"The price could be cheaper."

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

"Our customers have seen a reduction in TCO."

More Pure Storage FlashBlade pricing and cost advice

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

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

"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."

"The solution's pricing is better compared to other products."

"My company is in Brazil, and making the payments in dollars is tough for our organization."

"The product has an annual licensing fee."

"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."

"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."
