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.

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

"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."

"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 is scalable."

"The initial setup was extremely simple and straightforward."

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

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

"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."

"It has good, reliable, fast storage."

More Pure FlashArray X NVMe pros

"It has good performance."

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

"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."

"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."

"Performance is a top feature."

"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."

"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."

"Using this solution has meant that I do not need to look for different partners to provide me with solutions like a backup service. Dell provides end to end solutions."

More Dell Unity XT pros

"The main advantage of this solution is performance."

"It provides multi-protocol, which is what gives the edge when it comes to big lineage PC workloads."

"The stability, speed, and reliability are the solution's best features. The information is also very secure."

"The initial setup is pretty straightforward."

"The solution allows us to segregate one storage unit from another."

"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."

"This storage solution is both stable and scalable, and it works for our needs."

More NetApp EF-Series All Flash Arrays pros

Cons

"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."

"The software layer has to improve."

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

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

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

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

"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."

More Pure FlashArray X NVMe cons

"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."

"It might be nice to have more integrated features instead of having everything as a separate module, like the networking. The networking is attached separately in the back. It would be nice if that was more integrated with less ports."

"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."

"The uses of tools to communicate with EMC directly. With EMC, I am not able to connect and resolve issues without assistance, so they can't do unattended maintenance on devices, which would be a massive benefit if they could."

"I haven't seen the roadmap for this solution."

"It is expensive, and the pricing could be better."

"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."

"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."

More Dell Unity XT cons

"This solution does not have any compression or deduplication."

"Better support technicians for CAPP."

"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"

"We need a center related to NetApp in Egypt so that we can deal with them directly."

"I would like to shrink it more, if we can. The smaller, the better."

"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."

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

"Things like the FlexClones, SnapVault, SnapMirror, all of that. Some of it's available on the EF series, but we like what we have in the FAS system."

Pricing and Cost Advice

"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 product is expensive."

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

"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."

"The licensing is on a yearly basis."

"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 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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing of Dell Unity XT is good."

"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

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

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."

"Our costs are roughly $200,000 a year."

"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."

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

More Dell Unity XT pricing and cost advice

"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."

"Cheaper pricing is always good. NetApp has been doing everything the right way. They've been figuring out things really well, going in the right direction."

"The price point for EF is considerably lower than the alternatives."

"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."

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

"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."

"The cost of our license is approximately $200,000 over three years for NetApp EF-Series All Flash Arrays. There can be additional costs for storage. For example, if you want to have eight terabytes."

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

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."
