Eric Black - PeerSpot reviewer
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.

Shared storage capabilities provide enterprise value with good reliability
Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.
Juan-Contreras - PeerSpot reviewer
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 onboarding and integrated monitoring tools are pretty good."
"The most valuable features are the Metro clustering, and disaster recovery."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"I would rate Pure Storage FlashBlade a ten out of ten."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"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."
"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"I rate the stability of Amazon FSx ten out of ten."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"The shared storage capability is highly valuable."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
"The solution's most valuable feature is the Prism Central centralized management console."
"The initial setup is pretty straightforward. With a few clicks, you can stand up your storage. It reduces the overall life cycle of deployment within the ecosystem."
"The most valuable feature of Nutanix Unified Storage is redundancy."
"What I like most about Nutanix Files Storage is the way it makes copies of the data. The solution also has high availability, which is excellent. Another valuable feature of Nutanix Files Storage is self-service, so users won't have to depend on the IT team much."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"DR and the replication power are valuable."
"I like its interface. It is very interactive and simple to use."
 

Cons

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"The feature that we're waiting on is better integration with the cell services."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"Its configuration should be easier."
"I want efficiency. FlashBlade doesn't have efficiency now."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"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."
"I would also like to see better support for CIFS workloads."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."
"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."
"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."
"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."
"The feature request I have is for the consistent improvement of how user account permissions are assigned in Nutanix Unified Storage."
"From a management side, the one thing I would prefer is if it were a bit less expensive for smaller enterprises. It's a bit costly. If they provided flexible modules where you could pick and choose features, and only pay for what you use, that would be an improvement."
"The product does not offer one console."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
 

Pricing and Cost Advice

"The product is very expensive."
"The price of this solution could be made more affordable."
"Our licensing is renewed annually."
"The pricing for FlashBlade is between cheap and moderate."
"Our customers have seen a reduction in TCO."
"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."
"We used a reseller for the purchase."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"The price of the license is expensive when comparing it to traditional storage."
"It is not too high for what we are using."
"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."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"I'm happy with the cost and licensing because I don't have big volumes."
"In my opinion, the product is fairly priced."
"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
