Chief Technology Officer at Lambda256

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

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

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"The solution uses newer technology for deduplication and compression."

"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 latency is good."

"The most valuable feature of this solution is its ease of use."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

More Pure FlashArray X NVMe pros

"Very good IOPS performance"

"Thin storage allocation"

"XtremIO is very stable."

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

"It is great for applications like Microsoft Exchange, ERP, SQL and VDI; basically saved the VDI buy-in from users, as now performance was seamless in comparison to a physical PC."

"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%."

"I like the deduplication and auto-tiering features."

"The solution's most valuable feature is its high performance."

More Dell XtremIO pros

"The most valuable feature of the solution is that the tool provides good value for somebody who needs an affordable and reliable storage solution."

"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."

"Has very good deduplication and encryption features."

"The valuable feature is the ability to work with the Veeam software to reduce the backup windows."

"It is a very scalable solution."

"The most valuable features are the deduplication and compression capabilities."

"Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."

"The hardware is strong and all the equipment has a good infrastructure. Personally, I think it's the best storage product in HPE for small to medium-sized businesses."

More HPE StoreOnce pros

Cons

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

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

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

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"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."

"We need better data deduplication."

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

"The software layer has to improve."

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."

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

"The product is highly expensive. Additionally, there is a significant lack of training, support documents, and forums available for Dell XtremIO, making troubleshooting difficult for third-party individuals."

"The product is highly expensive."

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

"Scalability could be better."

"Ease of use is key in the converged and hyper-converged world that requires administrators to have both hypervisor and storage skills."

More Dell XtremIO cons

"HPE StoreOnce could improve the capacity support."

"Its customer service could be faster."

"The platform's price could be lower."

"The web interface, ease of use, and GUI all need to be improved."

"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."

"The product's price could be better."

"While StoreOnce has many features, it needs to focus on integrating with third-party backup software solutions."

"HPE StoreOnce needs to provide a SaaS solution by offering high-density disks."

More HPE StoreOnce cons

Pricing and Cost Advice

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

"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."

"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."

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

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

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

"We pay approximately $50,000 USD per year in licensing fees."

"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)."

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

"It is costly but worth it."

"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."

"Pricing and licensing are in line with other products from other manufacturers. You get what you pay for."

"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."

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

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

More Dell XtremIO pricing and cost advice

"There are costs for additional storage and space."

"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."

"The licensing costs is capacity-based and come bundled with support."

"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."

"The price of the product is reasonable."

"The solution is pretty expensive."

"I rate the platform's pricing a seven out of ten."

"I would rate it around two or three because, compared to others, it tends to be higher priced."
