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.
Alan Powers - PeerSpot reviewer

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

"After the testing, it was clear to us that the Pure FlashArray X NVMe was the easiest to manage and configure and had the best performance that we had seen in all the arrays."
"What we've seen on the Xs, and the Pures in general, is that we can scale way beyond what we need to without any degradation in performance."
"Being able to have broken files on-site on the same appliance is quite useful."
"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 duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"It has good, reliable, and fast storage."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Its speed is superior to our existing Unity x00 model and it has performed substantially better than our x00 model and a little bit better than our x50 model."
"We have zero downtime."
"It has definitely improved our speed, storage space, and recovery times."
"For all the deployments that I've seen or done, its been a rock solid platform."
"Simplicity and stability are very important for me, and this solution is very simple to use, it's very efficient and a customer won't make many mistakes when using it."
"It's the storage backbone for our virtual environment."
"Dell SC Series offers a lot of performance, being one of the best performing storages Dell ever made."
"It had many features, like a snapshot, replication, on-the-file RAID levels, mix-and-match files, those kinds of things."
"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."
"This has been one of the most reliable storage systems that I have ever used."
"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."
 

Cons

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We need better data deduplication."
"We have run into a couple of instances recently where we are running out of space."
"They could add more support for file storage and different types of storage."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"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."
"There is room for improvement in the pricing of the product."
"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."
"They need to make it a little cheaper."
"The configuration could be easier in Dell EMC SC Series."
"The ease of use could be improved. It took me a while to learn it."
"What I understand is that this is a 13 year old architecture, so it has lived its life and they're phasing it out. 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. At that time, it had the longevity to go to 100GB as well. It got us thinking about, when we go into the containerized architecture, what do we need to do to fix the infrastructure?"
"It's definitely affordable. Of course, it would be better if they made it cheaper, even more affordable."
"The initial setup is somewhat complex and should be made simpler to do."
"This product should be a lot more user-friendly."
"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."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The support cost per array is about $20,000 a year for 24/7 support."
"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 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."
"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."
"The licensing is on a yearly basis."
"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."
"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 have the basic license for the use of this solution and it is a permanent license. The overall cost could be less, it is expensive."
"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."
"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."
"This solution could be better priced in comparison with other vendors."
"We have found the solution to be affordable."
"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."
"Pricing depends on varying life cycles."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
