Sales Manager at Multicomputos PR

Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Storage Engineer at Movate

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Ensures streamlined management, simplified infrastructure, and efficient data handling

It has effectively managed our unstructured data, including audio and video files. We've experienced smooth operations without any complaints regarding uploading or downloading videos. While video usage isn't as frequent, we primarily utilize it for downloading videos related to specific incidents for administrators or our police department. We've encountered no issues uploading files of any kind. Transitioning from VMware to Nutanix has highlighted the overall flexibility of Nutanix's platform. Unlike VMware's three-tier system, Nutanix simplifies the learning curve by streamlining operations. The update process, in particular, has been favorable, with no critical issues encountered. The resiliency of Nutanix hasn't been thoroughly tested in our environment so far. However, I routinely check fault tolerance settings to ensure they meet our requirements. During the update process, I've observed critical errors occur as hosts restart, but Nutanix's self-healing mechanism handles these issues seamlessly. The benefit of using Nutanix is evident in several ways. Firstly, we've effectively compressed our storage while significantly expanding our overall storage pool. Previously, our service had a capacity of twenty-five terabytes, but with Nutanix, we've scaled up to a hundred and twenty terabytes physically and approximately fifty terabytes logically. This expansion has been accompanied by noticeable improvements in performance, particularly with reduced latency and IOPS well within the boundaries of our equipment. All our resources are centralized in a single location for managing and running storage: our data center. We operate three Nutanix nodes within this center, effectively managing everything from one central location. We don't have any other locations outside of our data center running a Nutanix cluster. Nutanix's capability to eliminate silos within our organization's storage infrastructure was discussed during our recent call with the engineer. Although we haven't explored this feature extensively yet, there's a forthcoming project where we anticipate leveraging it.One thing I'd appreciate is having a desktop application similar to what VMware offered. With VMware, I could download a separate client program onto my computer, allowing me to log in directly rather than accessing the host through a browser.

Quotes from Members

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

Pros

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint.

Cons

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"I'd like to see the product implement active replication for vehicles such as VMware."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"The tool's portfolio is minimal. It is expensive."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"The tool's pricing is higher than competitors."

More Pure FlashArray X NVMe cons

"Snapshots are not as easy to access as on a NetApp device."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"It's somewhat scalable, but maybe not so much as some of the competition."

"In future releases, I look forward to more AI features."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

More DDN IntelliFlash cons

Pricing and Cost Advice

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The licensing is on a yearly basis."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"The support cost per array is about $20,000 a year for 24/7 support."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"Our licensing fees are $500,000+ USD."

More Pure FlashArray X NVMe pricing and cost advice

"I think we pay around 100 grand per year for three arrays or four arrays."

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"In my opinion, the product is fairly priced."

"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."

"The product has an annual licensing fee."

"I'm happy with the cost and licensing because I don't have big volumes."

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

"The solution’s pricing could be cheaper."

"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."

"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."
