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.

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.

Good performance and reliable but the setup is complex
We would like to see a self-sufficient installation. Nowadays it's open-source, but the installation is still tied to the vendor, which means it is unlikely that it is going to scale. I want them to tap into the broader community. It is really emerging, they have a year over year, 50% annual growth. With a 10-year-old company, it will certainly bring a lot of interest, and will certainly make it more successful, if they tap into that growing customer base. They have to make themselves relevant to the industry. The industry is totally geared to the Cloud, DevOps, and geared for agility. The software with the appliance in my set is already outdated, and it is not that it cannot sell, but it has to be tapping into the emerging and growing sectors to continue with the customers and businesses. This is what the requirement is, to improve their technology. Which means that they have to make themselves relevant to the industry.

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."
"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."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"We can capacity plan at a greater level than we used to."
"It helps simplify our storage, because the user interface is very simple and the installation is easy."
"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."
"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."
"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
"Currently, the most valuable aspect of our Nutanix implementation is its file storage functionality."
"They have well-documented best practices and the interface is good."
"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"The most valuable feature of Nutanix Unified Storage is redundancy."
"Workflow is easy to manage and maintain."
"The technology is stable which is good."
 

Cons

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"The documentational aspect of FlashBlade needs improvement."
"There could be improvements in public cloud integration."
"The solution is expensive."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"I would like to see the licensing fees improved as well as the price per terabytes."
"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."
"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."
"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."
"The graphical user interface could provide more detail. It would be nice if we could click on the service and get some expanded definitions of them. When hiring new people, it's difficult to teach them how everything works, but if they can access everything, they can teach themselves."
"Perhaps Unified Storage could be improved by including artificial intelligence to make searches more effective. Also, if someone has access who shouldn't, it could automatically update, so I do not need to physically remove permission. The platform could do it automatically. AI could make it more self-service."
"Lowering the price would improve this product."
"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."
"The solution should keep adding new features to be competitive in the market."
"The solution's monitoring and security features could be improved."
"I haven't had any issues with the solution so far."
"We would like to see a self-sufficient installation."
"Lacks some ability to integrate with different systems."
