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 data replication and fast IOPS have improved operational performance

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.

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

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

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

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

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

"Technical support has been helpful and responsive."

"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."

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

More Pure FlashArray X NVMe pros

"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."

"I like that the performance is very good."

"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."

"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."

"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."

"It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."

"Inline data reduction is pretty impressive."

"The most valuable feature of Dell Unity XT is the GUI, it is very good. End users can manage using it. Additionally, the documentation is of high quality and it integrates well."

More Dell Unity XT pros

"It was very easy and straightforward to setup."

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

"The most valuable features are that it is fast and reliable."

"The speed and scalability of Dell XtremIO are significant features that improve data storage management."

"The initial setup is straightforward."

"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."

"XtremIO is very stable."

"Thin storage allocation"

More Dell XtremIO pros

Cons

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

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

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

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

"The tool's portfolio is minimal. It is expensive."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

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

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

More Pure FlashArray X NVMe cons

"Scalability for the 650F is good, but I was expecting a little bit more."

"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."

"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."

"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."

"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."

"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."

"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."

"A customer had to buy VMX because Unity didn't have WORM."

More Dell Unity XT cons

"The product is highly expensive."

"XtremIO needs to be lower priced. It also needs better endpoints and scalability."

"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."

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

"This solution is geared toward enterprise-level companies. Small and medium-sized businesses would find it extremely expensive."

"Management and reporting need improvement."

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

"If you are looking at flash storage solutions, XtremIO doesn't offer any unique features. Most of my customers are migrating their workload from XtremIO to other formats because of this."

More Dell XtremIO cons

Pricing and Cost Advice

"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 licensing is on a yearly basis."

"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."

"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."

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

"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."

"Given its price, Pure is not the first option."

More Pure FlashArray X NVMe pricing and cost advice

"The product’s pricing should be improved."

"Our CAPEX was close to $42,000 and operating costs are below $1000."

"The ROI is right where we need it to be. It's a reasonably priced array."

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."

"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"

"Pricing is as high as it has ever been for EMC."

"It is an average priced solution."

"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."

More Dell Unity XT pricing and cost advice

"This solution is a little bit pricey."

"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."

"It's not cheap, but it absolutely gets the job done. I don't have any real comment regarding licensing specifically."

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

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

"Dell XtremIO's price is affordable and I would rate it a five out of ten."

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

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."
