Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Efficient and straightforward setup boosts data management capabilities

Stanislaw Jagielski

Trainer, Storage Consultant at Oxon

Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage. It provides a lot of features suited for complex systems, such as scalability and the ability to define multi-domain systems, which are beneficial for data management and storage separation. It is efficient from the customer's point of view, offering deduplication at both the volume and file levels. The configuration and setup are straightforward, provided one has knowledge in setting up network infrastructure like VLANs. It is easy to install, use, and configure, making it a reliable product.

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

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

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

"The most valuable features of this solution are its ease of use and performance."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

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

"The high availability of the product is the most valuable feature."

"The solution is very straightforward to set up."

"The solution's most valuable features are the inline data reduction and deduplication."

"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."

"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."

"We've seen great enhancements from the performance point of view. There's good availability, stability, and continuity, but the performance actually has increased by 60 or 70%."

"XtremIO is very stable."

"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."

"Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage."

"The most valuable features include the easy manageability of snapshots and its excellent performance in large-scale workloads."

More Dell XtremIO pros

"It has seamless expandability."

"Its most valuable feature is simplicity. It is so easy to use. Upgrades are easy. It is easy in terms of disaster recovery, failover, database provisioning, and reporting. Everything about it is just simple."

"Data locality provides super-fast data access and ultra-low latency."

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

"The most valuable features are its ease of use and its good performance."

"The hyperconvergence service, as well as the DR solution, are game-changers for Nutanix."

"It is less expensive than VMware products. It is also a little bit more flexible, but it really comes down to price for us."

"The ease of deployment is very good."

More Nutanix Cloud Infrastructure (NCI) pros

Cons

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"It is on the expensive side."

"We need better data deduplication."

"The UI for this solution needs to be improved."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"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."

"I'd like to see the product implement active replication for vehicles such as VMware."

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

More Pure FlashArray X NVMe cons

"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."

"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."

"I would like to see the ease of deployment and built-in Metro clustering."

"Get rid of the Java aspect of the GUI console."

"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."

"The implementation isn't exactly complex, but the solution should have some enhancements in it to make the process more centralized."

"It needs a way to determine the deduplication of each LUN and what the impact would be if we were to move data from one LUN to another."

"The GUI could be modified more in terms of how the different components are linked to each other."

More Dell XtremIO cons

"In Thailand, there really isn't a cloud version of Nutanx available to us."

"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."

"I feel like the flow chart and the automated processes have some room for improvement. They're nearly there, and the rest is fine. They've improved a lot over the past few years."

"It is a CentOS-based operating system, but CentOS releases security patches almost every week or every other week. However, Nutanix releases their upgrade at three or four month intervals. According to my organization's SLA, if a critical patch is released during that time, then I need to implement the patches within 30 days. If it is a standard patch, then I need to patch it within 60 days. Since that is my SLA, I cannot meet my SLA for security because Nutanix will not release the upgrade within these 30 days. Between the critical patch release and the Nutanix release, my customers say they are vulnerable and I am accepting the risk while the SLA is breached."

"We ran into an issue as a managed service provider because Acropolis isn't designed to be used the way we are running it. For example, if we want to deploy a Kubernetes service, the customer networks need to reach our protected cluster network. We have isolated our customers in separate VLANs. However, our customers' networks must access our cluster network to get features like iSCSI or Kubernetes to run. It's challenging."

"The product requires a lot of resources."

"It would be great if it could emulate some of the features that their competitor VMware has, for example port mirroring or Netflow output at hypervisor level."

"Some clients find the solution's cost to be too high."

Pricing and Cost Advice

"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."

"The licensing is on a yearly basis."

"The product is expensive."

"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."

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

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

"With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms)."

"It is costly but worth it."

"XtremIO is an all-flash array, which means it's a costly solution. When compared with general mid-range storage solutions, this is more expensive. As far as I know, there are no additional costs besides the license."

"XtremIO is pretty straightforward about pricing. However, you need to look at your data so you can estimate, with the advice of DEL EMC, what data reduction ratio you will reach. In our case, a 3:1 reduction ration gave us a positive case compared to other storage arrays."

"The license for XtremIO is in the box, so you don't have to buy anything."

"There are costs in addition to the standard licensing fees."

"This solution is a little bit pricey."

"The price of the solution should be reduced. The price matches the price of a VMAX service but it does not have the capability of a VMAX service. However, the prices of Dell EMC XtremIO can be reduceable."

More Dell XtremIO pricing and cost advice

"This product is expensive, but they do have discounts. At one point, I saw that they were giving a 70% or 80% discount, which is a good thing, but maybe they should have a more realistic price and then a 5% to 10% discount."

"It is not cheap, but if you look at the return on investment and the total cost of ownership, it is worth the price."

"Pricing varies greatly between license and editions."

"There is a license required for this solution and my clients usually purchase a two-year license with extended support. The price of the solution could be reduced, it is more expensive than competitors."

"It is slightly more expensive compared to a standard, on-prem, bare-metal configuration. There is about a 30 percent overhead there."

"The price of the solution is high."

"I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price."

"The price of the solution is expensive. However, the price to performance is good. The cost for development and installation is very low."
