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 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.

Managing Director at GCET

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"The solution is scalable."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

"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."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

"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."

"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 solution uses newer technology for deduplication and compression."

More Pure FlashArray X NVMe pros

"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."

"It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."

"Snapshots provide a unique feature for testing and make management more comfortable and easy."

"Dell Unity XT is user-friendly and easy to use."

"The setup and installation procedures are easy."

"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."

"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."

"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."

More Dell Unity XT pros

"I would have to say performance at this point, because the application it is based on is so diverse."

"Having the option of such high-speed storage in the data center is what makes it valuable."

"The NetApp EF-Series gave our organization easy access to our data bases."

"We use it for our VDI environment, and have not had any complaints with it."

"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."

"The management of it is very simple. that is the most valuable feature."

"Considering the cost, I find NetApp EF-Series All Flash Arrays to be the best storage available in the market."

"Some of the valuable features include MetroCluster switchover, in terms of disaster recovery, it is easy to use, and flexible."

More NetApp EF-Series All Flash Arrays pros

Cons

"There is room for improvement in the pricing of the product."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"We need better data deduplication."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

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

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

More Pure FlashArray X NVMe cons

"I rate the scalability of Dell Unity XT a nine out of ten."

"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."

"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."

"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."

"They should update to the cloud."

"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."

"The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed. If it's on, it's on. So we have to be a little more WAN-sensitive, in some applications, which means we can't put it everywhere. That's the biggest issue for us, by far."

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

More Dell Unity XT cons

"Better support technicians for CAPP."

"This solution has limited storage."

"Better integration with other brands is important so we would like to see it easier to integrate."

"A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series."

"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."

"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."

"The initial setup phase of NetApp EF-Series All Flash Arrays is not straightforward and needs improvement."

"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."

More NetApp EF-Series All Flash Arrays cons

Pricing and Cost Advice

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

"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."

"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."

"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."

"The product is expensive."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Pricing for this product is manageable, though slightly higher than comparable products."

"The product’s pricing should be improved."

"We purchased a five-year warranty."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."

"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."

"It is an average priced solution."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."

More Dell Unity XT pricing and cost advice

"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."

"This solution is not available to many users because the cost is very expensive."

"One has to opt for a perpetual-based licensing model for one year or three years. After three years, you need to renew the license."

"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."

"It's a lot cheaper than what the other vendors have for the same type of environment. It saves us money."

"Its cost-effectiveness is a major selling point. Compared to other storage vendors, the EF-Series offers excellent value for its price. It's truly a leading product in the industry."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."

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."
