Featured Reviews

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.

Enables seamless file distribution while benefiting from scalability but could use simplified implementation
IBM Storage Fusion is used in telecoms. It is a file center that receives and shares files. It is also used for writing the CDR zone on the storage, since it offers a cost-effective solution for large-scale storage needs in a telecom setup The deployment of Storage Fusion has been new for us in…
Vishnu Mohan - PeerSpot reviewer
Centralized management and high resiliency streamline data storage with immediate benefits and scalability
The most effective features of Nutanix Unified Storage (NUS) for us are about making multiple copies of our data across hardware nodes, ensuring that if there is a hardware failure, we still don't lose our data, which I think is the most important. Also, they have a file solution that is good for file shares, and that is of value to us. The switch from solutions such as IBM to Nutanix Unified Storage (NUS) was driven by the need for different skill sets for a separate storage team and separate compute team. Maintaining these old devices was getting prohibitively high, so consolidating everything onto Nutanix Unified Storage (NUS) made sense and allowed one set of Nutanix engineers to manage the entire estate.

Quotes from Members

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

Pros

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"Using this solution has made our backups more reliable."
"The main feature I have found to be product replication."
"Speed and ease of use are the two most valuable features."
"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"The initial setup is pretty quick."
"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."
"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."
"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."
"What I appreciate most about Nutanix Unified Storage (NUS) is how easy it is to use and how simple it is to create new volumes and containers, and it's pretty quick."
"It is very scalable."
"The most valuable features are the interface and support."
"The simplicity of management is valuable because, in more traditional environments, the platform updates are much more complex."
"The deployment was very easy."
"The most important point is the simplicity of the API integration. We can leverage the API integrations and connect our hybrid-cloud network environment with Nutanix's cloud storage."
"We have seen reduced overheads and increased efficiency with Nutanix Unified Storage (NUS)."
"The aspect of the product that I like the most is its simplicity."
 

Cons

"The feature that we're waiting on is better integration with the cell services."
"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"I have not seen ROI."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"I want efficiency. FlashBlade doesn't have efficiency now."
"The implementation is complex, especially when using custom servers."
"Security is an area for improvement. When there are vulnerabilities, there needs to be a faster approval process. The solution needs to automatically target the vulnerabilities and not waste too much time."
"While Unified Storage has evolved a lot over time, its database handling needs to improve a little. There could be an improvement in terms of costs. It's a little expensive for Brazil but still delivers a lot of performance."
"We have issues with software updates occasionally."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
"The interface is not logical. It should be a little simpler."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"If they can add an integrated DLP feature, it would be great."
"Nutanix could improve the ability to track user actions, such as identifying who deleted a folder."
 

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."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"I feel that the price could always be lowered."
"We used a reseller for the purchase."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"The price could be cheaper."
Information not available
"The solution's pricing is better compared to other products."
"The pricing is fair."
"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."
"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."
"Nutanix is very competitive."
"The product is pricey."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."
