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

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"It has good, reliable, fast storage."

"The most valuable feature of this solution is reliability."

"The latency is good."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"The solution is very straightforward to set up."

"It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."

"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."

"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."

"This solution makes it easy to manage storage, provision new workloads, and scale-up."

"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."

"We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in."

"For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed."

"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."

More Dell Unity XT pros

"It has enterprise data services with consolidated storage data protection and disaster recovery. One valuable aspect is its efficiency as a robust platform. There is an ease of managing all processes. The data recovery process is remarkably fast. It’s a stable solution. The product is scalable. It provides high-speed live migration capability."

"Nutanix does a superb job with technical support."

"A lot of features are there, but for us, on the server administration side, creating a clone of the VM is valuable because many times, we have to deploy security patches. For deploying these patches, it helps to have a clone so that if something goes wrong, we can discard that VM and put back the clone VM. That is a very cool feature."

"The solution remains stable across versions."

"The most valuable feature I have found to be the Acropolis Hypervisor (AHV)."

"The dashboard of Nutanix Acropolis AOS allows for simple management. The dashboard has all the information online about what's going on at any given time."

"The tool is simple, stable, and easy to upgrade. It also requires few resources to manage, which simplifies our work. The solution's ease of upgrading is its valuable feature. AHV, provided by Nutanix, is excellent in performance and ease of use. It's based on an open-source product called KVM, which I also use for other services."

"In general, being able to patch and not having to pay for SanDisk is the best thing about hyper-converged."

More Nutanix Cloud Infrastructure (NCI) pros

Cons

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"They could add more support for file storage and different types of storage."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"It is on the expensive side."

"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."

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

"It feels more suitable for small and medium-sized businesses rather than enterprises."

More Pure FlashArray X NVMe cons

"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."

"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."

"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."

"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."

"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."

"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."

"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."

"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."

More Dell Unity XT cons

"The licensing cost could be lower."

"When we have issues with the solution, they tend to be around networking."

"We have a team that does the implementation of the solution for our customers, it is better to have professionals handle the process."

"In the future, I would like to see multi-tenancy in Nutanix Acropolis AOS."

"For the company process, the price is too high."

"As of now, Acropolis and VMware cannot talk to each other. Until we have some kind of interface, it would be much better for Nutanix if they built an interface which can talk. Otherwise, if I have a VMware stack and I already have a Nutanix stack, I create containers, I create clusters on VMware, I create clusters on Nutanix. All of these clusters cannot talk to each other. Then it has to be then subverted as a parallel execution. What happens then is that I have to work in two different environments within my data center. Practically, they are two different data centers but physically and logically, they are one. If they cannot talk to each other that creates a lot of issues. That is something which Nutanix has to develop because for Nutanix it is very simple. For example, Oracle is using a function called GoldenGate. They have a feature called GoldenGate which allows them to talk to various different environments which must really help."

"The self-service side of the product needs to be improved. We should be able to add two-factor authentication and more security layers to it."

"As of now, Acropolis and VMware cannot talk to each other. Until we have some kind of interface, it would be much better for Nutanix if they built an interface that can talk. Otherwise, if I have a VMware stack and I already have a Nutanix stack, I can create containers, I create clusters on VMware, I create clusters on Nutanix."

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."

"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."

"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."

"With VMware, we pay $300,000 annually."

"The licensing is on a yearly basis."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."

"While it has a good price to start, they could always make it cheaper."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."

"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."

"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."

"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."

"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."

More Dell Unity XT pricing and cost advice

"While cost may seem higher than your traditional 3-tier architecture, you need to look at the bigger picture. You're not just buying hardware here. You're buying a complete environment."

"The pricing is fair for the package."

"If they could further reduce the cost, that would be great. I would like to see the cost be less than the equivalent three-tier architecture."

"They should lower the price. If they did they would fall into a more competitive market because the price does scare a lot of potential customers away when they get the quote."

"Nutanix Cloud Infrastructure's core licensing needs to have an upper limit since processors are coming out with incredible numbers of cores on them."

"Nutanix Acropolis AOS price includes no additional costs for features."

"Its price is fine. I can't really complain about that."

"If a customer has been using VMware, the difference in pricing is lower. However, if they are looking to use the VMware, the price can be much higher depending on the license."

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."
