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

"I appreciate the performance."

"The high availability of the product is the most valuable feature."

"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 uses newer technology for deduplication and compression."

"The solution is very straightforward to set up."

"What I really like about this program, is that it is easy to use and easy to configurate."

"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."

"Technical support has been helpful and responsive."

More Pure FlashArray X NVMe pros

"The product offers good performance and is quite powerful."

"The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works."

"The user interface is good, I would rate it a nine out of ten."

"The process of reallocating data from fast disks (SSD or SAS) to slow disks (SATA) gives you better performance and better use of resources."

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

"The most valuable feature is the ability to replicate. We are running a financial company and it needs to be available 24/7. We can't afford any downtime."

"What is most valuable about the Dell EMC SC Series system was its reliability."

"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."

More Dell SC Series pros

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

"We have been working with the solution for around a year and so far it has shown itself to be stable."

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

"The solution is very easy to set up."

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

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

"Lenovo ThinkSystem DE Series is simple to use"

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

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."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"We need better data deduplication."

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

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

"Maybe the price can be reduced since the solution is very expensive."

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

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

More Pure FlashArray X NVMe cons

"There's always room for improvement in the operating code."

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

"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."

"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 initial setup is somewhat complex and should be made simpler to do."

"Compellent comes in the form of a component that's not true of a unified storage platform."

"While the price is competitive, in the next release it would be better if they could reduce the fees."

"Some menus aren't so intuitive."

More Dell SC Series cons

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

"In the next release, I would like to see support for Hyper-converged infrastructure."

"The features are limited."

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"Its performance could be faster."

"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."

"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

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

"The licensing is on a yearly basis."

"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 product is expensive."

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

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Compared to other solutions out there, it's affordable."

"Pricing depends on varying life cycles."

"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."

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

"We have found the solution to be affordable."

"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."

"The pricing of this solution is competitive."

"It's a very affordable solution."

More Dell SC Series pricing and cost advice

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

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

"It is an expensive solution."

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

"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."

"The solution's price could be better."

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

"The pricing for this solution is good compared to HP or Dell EMC."
