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.

Storage solutions accommodate diverse drives and offers good resiliency

Technical support is good. I can log complaints online through the portal and have engineers in line. I can also take dedicated engineers if needed, although this involves a different support cost. As far as my requirements are concerned, it is working fine. There are two or three types of support. Standard support involves logging a complaint and receiving a call from the OEM on the same day, but hardware replacement takes two to three days. Advanced support offers instant replacement without delays. Hardware support terms include calling or emailing the company or logging the call in the portal to receive remote support, or getting a dedicated engineer or account manager from Dell.

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 very straightforward to set up."

"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 best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"The initial setup was extremely simple and straightforward."

"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."

"Technical support has been helpful and responsive."

"I appreciate the performance."

More Pure FlashArray X NVMe pros

"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."

"The interface is easy to use which makes the product user-friendly."

"Its leading feature is the price-performance ratio, which is very good."

"I think that Dell EMC is one of the best technical support services in Ukraine."

"Technical support is very good. I do use it from time to time and it's always excellent."

"The Dell support is helpful and the response is quick. The agents' knowledge is very good."

"Everything is sub-5 MS for us. What I've found is that, with all-flash, when an app from my business is slow, I pretty much know it's them and not me. It leads to a performance conversation that has really hit an interesting threshold point where we are better than what they need. So now we get to have that "refactoring your application" conversation a lot quicker because now the performance on the infrastructure side isn't in question anymore."

"The setup is straightforward."

More Dell SC Series pros

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"The solution's initial setup process is easy."

"Lenovo ThinkSystem DE Series is simple to use"

"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."

"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."

"The solution is very easy to set up."

More Lenovo ThinkSystem DE Series pros

Cons

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

"There are some challenges with data encryption and reduction."

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

"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's more multi-tenant functionality in their Pure1 manage portal that is lacking."

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

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

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

More Pure FlashArray X NVMe cons

"The administration and support (on the way that they delivered) was a little bit slow."

"Technical support should respond more quickly because the turnaround time is very high."

"Dell could improve the upgrading process."

"From a performance point of view, it's getting a bit old."

"If Dell SC Series wasn't being phased out, adding an NVMe tier and secure snapshots like those on the PowerStore platform would be beneficial."

"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."

"The connection should be better integrated with the network to offer a better view of the system."

"Licensing, especially on the storage line, could use some simplification. It's not terrible, but, for example, with the Isilon series, they've gone to completely a la carte. A la carte is very difficult to traverse, as to what you need. It would be more beneficial, at least from my point of view as a customer, if they did it more like car companies do, where there are package lines"

More Dell SC Series cons

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

"The product could support advanced software integrations."

"Improvements can be made to the product's performance."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"The features are limited."

"There could be a snapshot feature in the solution."

"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."

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."

"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."

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

"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."

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

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

"The licensing is on a yearly basis."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."

"This product is too expensive compared to others, and I don't see any value in using it."

"The SC Series was priced fairly. I wouldn't call it either expensive or cheap because we had a very tight budget, so if they were able to fit in that type of budget, they met our expectations."

"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."

"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."

"Pricing depends on varying life cycles."

"The pricing is reasonable, but it is expensive."

"There are costs involving the solution, vendor fees and product safety which are additional."

More Dell SC Series pricing and cost advice

"It is an expensive solution."

"The solution's price could be better."

"The pricing is fair and low compared to other products in this category."

"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"We have a five-year contract for providing support."

"The best thing about this solution is its price, which reduces our costs."

"For an all-flash setup, the cost is around $20,000 for a decent configuration."
