Eugene Hemphill - PeerSpot reviewer
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.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
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

"On a scale of one to ten, I rate Pure FlashArray as ten."
"The most valuable feature of this solution is reliability."
"The high availability of the product is the most valuable feature."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Integration is easy with this product."
"Quick Snapshots and cloning are key features."
"There has been no downtime. It has built-in redundancy upon redundancy."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing."
"I like how it separates the iSCSI drives from the standard shares. It has two different routes to it. I know most of the other solutions do this, but I just like the way that Dell EMC does it."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"It is a highly scalable solution."
"The solution's most valuable features are its support and speed."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."
"The most valuable feature is the storage density of the nodes. We went with the HP's low-density nodes."
"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."
"The reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."
"The benefit that our clients see is the security of the whole Nutanix platform where they have simplified usage."
 

Cons

"Maybe the price can be reduced since the solution is very expensive."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"There is room for improvement in the pricing of the product."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The software layer has to improve."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"I would like better monitoring capabilities: more historical data with more insight into the performance for the database. We now use a separate tool for it. Therefore, it would be nice if we could have that straight from the tool."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"The price of this product can be more cost-effective."
"The feature request I have is for the consistent improvement of how user account permissions are assigned in Nutanix Unified Storage."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
"I have heard that there have been latency problems."
"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."
"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."
"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."
"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."
"Pricing can always be better."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Given its price, Pure is not the first option."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"With VMware, we pay $300,000 annually."
"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."
"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."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."
"Pricing is as high as it has ever been for EMC."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"Our costs are roughly $200,000 a year."
"The ROI is right where we need it to be. It's a reasonably priced array."
"The product’s pricing should be improved."
"The pricing is a bit too high."
"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."
"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."
"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"The solution's pricing is better compared to other products."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
