Eugene Hemphill

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.

Anil Rahulwar

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.

System Administrator at a educational organization with 501-1,000 employees

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

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"What I really like about this program, is that it is easy to use and easy to configurate."

"It has benefited my organization because it has reduced time to insights."

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The solution is very straightforward to set up."

More Pure FlashArray X NVMe pros

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"The initial setup is straightforward."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It performed great originally, and when it performed great, it was awesome."

"Data Compression: Up to 80% space reduction in the database"

"We use IntelliFlash products for larger environments, like Qatar Airways."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

More DDN IntelliFlash pros

"The capacity is very good. They use fewer nodes than before. Each node is isolated with the CPU with the performance. It is a cluster node but works separately, so the performance will be tripled."

"Some of the features that we use include replication and snapshot capabilities, especially from remote locations to our data centers. The main benefit our company sees from using Nutanix Unified Storage is simplification. In the past, we used three-tier solutions with a lot of complexity and operational overhead. Now, we want to focus on the layers above. I want to have storage available, but I don't want to have to think about it. I want it to work without any issues."

"What I found most valuable in Nutanix Files Storage is its high availability and ability to scale out with many VMs."

"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."

"The most valuable feature of Nutanix Unified Storage is SMB file sharing."

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

"It gives more security that the data isn't going to get lost."

"For somebody like me who grew up building what others call three-tier and I call traditional architecture, the valuable thing is that you can now buy it. You can have new deployments and infrastructure up and running with very little infrastructure behind it."

Cons

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"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."

"They could add more support for file storage and different types of storage."

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"The UI for this solution needs to be improved."

More Pure FlashArray X NVMe cons

"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."

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

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

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

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"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."

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

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

More DDN IntelliFlash cons

"I have heard that there have been latency problems."

"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."

"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."

"The interface is not logical. It should be a little simpler."

"It could be more user-friendly."

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

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

"The solution should include more protocols to access data."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

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

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"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."

"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."

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

"With VMware, we pay $300,000 annually."

"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."

"As far as the licensing costs, everything is included in the license."

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."

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

"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."

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

"The product is pricey."

"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."

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

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