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.

A robust solution with good performance and support
This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

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

"It is very easy to use, and it is very fast."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"The product is scalable and easy to expand."
"The most valuable feature is Safe Mode."
"Using this solution has made our backups more reliable."
"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."
"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."
"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."
"The ease of use is the solution's most valuable aspect. It's very user-friendly."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"The scalability, ease of use, and technical support are the most valuable features of Nutanix Unified Storage."
"The most valuable feature of Nutanix Unified Storage is SMB file sharing."
"The best Nutanix Unified Storage features are its recovery and data speeds. It has resolved the issue of accessing information quickly."
"Management-wise, it has made work a lot easier. It is all in one place physically. It is much better now."
"It is a highly scalable solution."
"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."
"The customer service executives of all Nutanix products are active and responsive."
"The most valuable feature is the easy interface."
 

Cons

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"I have not seen ROI."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"The speed could be improved."
"Its configuration should be easier."
"The solution is expensive."
"It's on the expensive side, as expected for a niche product."
"he interface is not user-friendly so the ease of use could be improved."
"The reporting mechanisms need improvement."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
"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."
"Its licensing can be better. They can make it easier for us to scale our infrastructure."
"The interface could be improved."
"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."
"Lowering the price would improve this product."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
"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."
 

Pricing and Cost Advice

"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."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"I feel that the price could always be lowered."
"The price of this solution could be made more affordable."
"The pricing for FlashBlade is between cheap and moderate."
"The price is a little high."
"Our licensing is renewed annually."
"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."
"If you are cost-sensitive then this solution is not for you."
"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."
"It is not too high for what we are using."
"I'm happy with the cost and licensing because I don't have big volumes."
"Nutanix is very competitive."
"The product has an annual licensing fee."
"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."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
"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."
