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.

Efficient data replication and fast IOPS have improved operational performance

Syed Habib

Head of Infrastructure Security (S.A.V.P) at EXIM Bank Ltd

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.

Offers a unified platform, reduces downtime, and simple updates

MahendraPanchotiya

Infrastructure Manager at ER Tech Pros

Nutanix offers a unified platform for managing databases, virtual machines, and applications. This simplifies management by consolidating everything into a single interface. While Nutanix may have a higher upfront cost compared to other hypervisors, it can significantly reduce the resources needed for infrastructure management. With our previous hypervisor, we needed nearly ten IT personnel. Nutanix has allowed us to streamline our team to just three members. We use a combination of database technologies, including SQL databases and web servers such as IIS, BHP, and NGINX. Nutanix features helped our organization reduce downtime. I don't recall the last time we had downtime related to Nutanix because it is such a stable product. Nutanix, a reliable product, helps us streamline our processes, which in turn improves company revenue. We began to see the benefits after two years, with a 40 percent reduction in operational costs. We migrated 200 servers from AWS to Nutanix. Nutanix may not consolidate applications, but it helps us run them more efficiently on its platform. Updating is simple with one click. I would rate the updating processes 10 out of 10. Adding compute and storage on demand is not difficult. However, we need to factor in the existing and new firmware and software requirements.

Quotes from Members

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

Pros

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"Overall stability is very good. It is a very stable solution."

"I appreciate the performance."

"It has benefited my organization because it has reduced time to insights."

"It has good, reliable, fast storage."

"What I really like about this program, is that it is easy to use and easy to configurate."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency. The results were visible in the front-end systems, and all users noticed the improvement."

"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."

"I like the easy management with the new Unisphere management and the HTML5 interface."

"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."

"We can sleep at night because the support is great."

"Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution."

"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."

"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."

More Dell Unity XT pros

"In addition to the hyper-converged infrastructure, most of our clients are pleased with Acropolis' built-in replication in terms of the DR setup. Our clients also like Prism Central's advanced management and analytics, and many find Nutanix Flow and playbooks incredibly useful."

"SRM capabilities for replication have been proven reliable and very useful for our organization."

"We like that the size of the box is 1U or 2U only, and all the servers are fit into that box. The ease of operation is there. All the servers and the SAN storage are inside the box."

"The administration console, automation, and the first cluster are all valuable features."

"Performing a Nutanix software upgrade is a very simple and non-disruptive process."

"Management is simple"

"Hyperconverged Infrastructure is the most valuable feature of Nutanix Cloud Infrastructure."

"What I like the most are the high-availability and scalability."

More Nutanix Cloud Infrastructure (NCI) pros

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"Maybe the price can be reduced since the solution is very expensive."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"In terms of what needs improvement, the dashboard and management could be simplified."

"The tool's portfolio is minimal. It is expensive."

"There is room for improvement in the pricing of the product."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"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."

More Pure FlashArray X NVMe cons

"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."

"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."

"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."

"The user interface could use improvement."

"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."

"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."

"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."

"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."

More Dell Unity XT cons

"I'm sure there are a lot of things that could be improved, but I'm actually very satisfied with this product. There may be some possibilities to move the virtual server dismounting points or to move the server from one group to another, but I can't think of any special improvements or update features."

"USB dongle-based licenses do not allow us to directly locate the USB ports on Nutanix."

"They could improve the graphical user interface."

"I'd like it to be more API-based."

"The storage and back-up facilities could be improved. We need day-to-day encrypting of the database."

"One thing to keep in mind is that only experts can use it. It has to be in the proper hands, instead of going to XYZ people just for some cost savings. So lift-and-shift and migrations might be tricky, because it is not like a VMware."

"Make it easier to manage."

"There are other services that Nutanix has that could be improved, but I'm not very familiar with the other services of Nutanix, such as Era and Flow. However, they seem a bit hard for us to implement and integrate with the Nutanix Acropolis AOS and other Nutanix tools. We would not dare to implement those other Nutanix solutions into Nutanix Acropolis AOS right now. The implementation of that tool could be the problem, I am a bit hesitant to implement the other tools into Nutanix Acropolis AOS."

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."

"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."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"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."

"Given its price, Pure is not the first option."

"As far as the licensing costs, everything is included in the license."

More Pure FlashArray X NVMe pricing and cost advice

"The solution should be cheaper."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."

"We purchased a five-year warranty."

"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."

"Our costs are roughly $200,000 a year."

"It is an average priced solution."

"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."

More Dell Unity XT pricing and cost advice

"The price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."

"Nutanix Cloud Infrastructure could be cheaper. It's costly to upgrade the solution. There are no additional costs aside from the license."

"Nutanix Cloud Infrastructure is expensive."

"Our customers are on three years license to use Nutanix Acropolis AOS. The price of the solution includes all features and support."

"Cost-wise, it is very good. It is like the hypervisor cost is not there. We only need to pay for the system and AOS licenses."

"Our Nutanix license is for five years. There is a support arrangement there, but that aspect is more or less taken care of during the initial installation. With HCI architecture, whenever we do any kind of auto scaling or scaling of servers and resources, there is a significant amount of software licensing involved."

"We just have a support license for Nutanix."

"The price of the license for Nutanix Acropolis AOS is less expensive than the competition. There is a favorable cost saving. Having only the need to deal with a single vendor, the management of the customer's entire stack is cost-effective."

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "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." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
