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

"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."

"The solution is very straightforward to set up."

"Speed has definitely been a big improvement for us; we were running a bunch of iSCSI to EMC VNX and that had a gigabyte bottleneck, and now, since we're running through a true fiber channel to the Pure array, we're getting 32-gigabyte bandwidth, which means the speed and accessibility for our users and our customers have definitely improved."

"One of the best features is the support, which is excellent."

"The administration and the stability are very good."

"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."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The most valuable features of this solution are its ease of use and performance."

More Everpure FlashArray X NVMe pros

"I would recommend to buy Dell EMC 3020 to anyone researching these type of solutions."

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

"It is a stable solution; we haven't had any downtime."

"Dell SC Series offers a lot of performance, being one of the best performing storages Dell ever made."

"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 solution is stable."

"The setup is straightforward."

"The performance was staggering and it was more than what we paid for."

More Dell SC Series pros

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

"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

"It is on the expensive side."

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

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

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

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

"I'd like to see the product implement active replication for vehicles such as VMware."

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

"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."

More Everpure FlashArray X NVMe cons

"For example, for a 4TB SSD, they may charge you seven grand or eight grand. It's expensive."

"This solution could be improved if overall performance was improved and operated with a higher speed and supported a higher volume of RAM."

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

"I would rate the SC Series at seven out of ten right now. That might change as future releases come out and more functionality comes into the product."

"Matching color coding during zoning is sometimes a little bit annoying."

"It would be helpful if the solution offered higher performance, at least on the back end."

"To begin with, we were ready to throw it out the window."

"Snapshots in VMware. You can’t do snapshots since the storage itself does that. Therefore, some apps (Veeam, for example) don’t work well with this kind of tiering storage."

More Dell SC Series cons

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

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

Pricing and Cost Advice

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

"The product is expensive."

"As far as the licensing costs, everything is included in the license."

"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."

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

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

"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 Everpure FlashArray X NVMe pricing and cost advice

"We have reviewed many platforms over the years. It is probably the best solution for its value."

"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."

"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 a very affordable solution."

"The pricing of Dell EMC Compellent is competitive."

"Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution."

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

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

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."
