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 and straightforward setup boosts data management capabilities

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.

Quotes from Members

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

Pros

"One of the best features is the support, which is excellent."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"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."

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

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

"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."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

More Pure FlashArray X NVMe pros

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

"Ease of management, aside from the serious performance, is the best feature."

"The guaranteed sub-millisecond response time for a 4K block."

"Initially, we faced numerous issues with our analytical systems. However, we saw performance improvement after the implementation of the solution."

"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."

"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."

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

"XtremIO is very stable."

More Dell XtremIO pros

"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."

"The servers are fast and affordable."

"The FlexClone feature is the solution's most valuable aspect."

"We are satisfied with the stability."

"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."

"The value we derive from using it is greater than other alternatives like HPE and Dell."

"Ability to cluster two storages together with HA availability."

More Lenovo ThinkSystem DM Series pros

Cons

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

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"The tool's pricing is higher than competitors."

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

"In the future, I would like to see integration with enterprise backup systems."

"Adding some functions to the product would be beneficial."

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

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

More Pure FlashArray X NVMe cons

"Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data."

"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."

"The physical architecture could use some higher levels of redundancy."

"The solution's stability has certain shortcomings where improvements are needed."

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

"The product could be improved by reducing the pricing and having better organization in their technical support team."

"It is very expensive to scale. You have to buy an additional system to extend from one disc, for instance. It is scalable, but extremely expensive to do so."

"The product is highly expensive."

More Dell XtremIO cons

"The licensing model needs to be revisited. It needs to be simplified."

"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."

"This is an expensive solution."

"The tool's pricing is high."

"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."

"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."

"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."

"Lenovo could have a wider variety of storage solutions in the NAS space."

More Lenovo ThinkSystem DM Series cons

Pricing and Cost Advice

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

"The product is expensive."

"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 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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"It is expensive if you need to increase scalability."

"The licensing cost is on a yearly subscription basis, which can be expensive but is necessary for ongoing support and services. The pricing could be improved to make it more accessible."

"It is costly but worth it."

"The initial purchase price was good but when you need to upgrade, it's a different story."

"This is the best flash array on the market for high-end workloads, so expect to pay for that. But the support subscription cost is fixed for seven years, which made it easier for us to plan on the maintenance costs."

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

"Don’t buy this array. You’re paying for loads of magic beans, since it’s mediocre at best for a platform in a rapidly growing field. Look instead at Pure Storage or something with variable block deduplication. You’ll end up spending less and getting a better product with actual support."

"It is great when a product can deliver high-end performance capabilities while offering a very competitive price point."

More Dell XtremIO pricing and cost advice

"The price of the Lenovo ThinkSystem DM Series is good."

"The solution is highly-priced."

"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."

"The solution's pricing is similar to Dell and HPE."
