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.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

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."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"The database workloads are pretty fast because I frequently move data from here to there."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

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

"The initial setup was extremely simple and straightforward."

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

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

More Pure FlashArray X NVMe pros

"The most valuable feature of the solution is its performance."

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

"The performance is good, which is important."

"It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."

"XtremIO is very stable."

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

"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%."

"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."

More Dell XtremIO pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

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

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

"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."

"It is on the expensive side."

"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."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

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

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

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."

"Sometimes we don't get an immediate response from the support team. The initial POC also took a lot of resources."

"The management should be improved and the GUI interface could be better and easier."

"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."

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

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

"XtremIO is coming to its end of life."

More Dell XtremIO cons

"The write performance could be improved because it is less than half of the read performance."

"The read/write ratio is an area in the solution with some flaws and needs improvement."

Pricing and Cost Advice

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

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

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

"The licensing is on a yearly basis."

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

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

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

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"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."

"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."

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

"Licensing is approximately $200,000 per year."

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

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

"You can get a two-year or three-year license for the tool. You can also opt for a perpetual-based licensing model, which can be renewed on a yearly or two-year basis."

More Dell XtremIO pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
