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.

User interface offers clarity and detailed information while technical support consistently delivers

The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"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."

"Overall stability is very good."

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

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

"The administration and the stability are 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."

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."

More Everpure FlashArray X NVMe pros

"Customers are most impressed with SC's provisioning because you don't need to buy a large amount of storage upfront. It's pay-as-you-grow. It also has solid compression and duplication features."

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

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

"One of the most valuable features is the capability to switch between all-flash to hybrid, which have have actually done for one of our arrays. We started with the hybrid, with the limited if I'm not mistaken, and then over a period of time, we swapped all the hybrids with the SSDs. This was one of the big features because it gave us the capability to not stick with just one kind of media. Secondly, since it has sorted clustering, we were able to bring in the newer boxes and have it all clustered together. These were the two main features that we really looked into, which benefited our use case from an expansion/growth perspective. Another valuable feature is the ease of management."

"Technical support has been quite good; we are very satisfied with the level of support we receive."

"I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures."

"Technical support is good."

"We see very low latency with very high IOPS for mixed workloads."

More Dell SC Series pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

"I would like to see replication and DR features in the next release of this solution."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"Pure is not flexible on your datapak expansions. You're locked into a certain amount of storage."

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

"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 solution should improve its logon requirements."

"The tool's pricing is higher than competitors."

"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."

More Everpure FlashArray X NVMe cons

"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."

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

"I think it would be nice if the connection were better integrated with the network so I could get a broader view of both the network and the system."

"Honestly, we were initially struggling with the integration with VMware (but it was fixed with the VMware 6.5) and, then, it was around a 10GB network."

"While the scalability is good, there are certain limitations."

"I don't think the solution is very scalable."

"This product should be a lot more user-friendly."

"The interface could be improved. It should have an application point of view."

More Dell SC Series cons

"The write performance could be improved because it is less than half of the read performance."

"The read/write ratio is an area in the solution with some flaws and needs improvement."

Pricing and Cost Advice

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

"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."

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

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

More Everpure FlashArray X NVMe pricing and cost advice

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

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

"It has a good price point and offers some value-added enterprise features."

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

"We were able to afford two tiers of flash storage at a price where the competition was giving us one tier or just a handful of discs."

"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."

"We have found it to be affordable. Comparing the cost with other hardware, it seems to be right in line with the compute and the storage that we get with it."

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

More Dell SC Series pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
