Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Superior platform with excellent snapshots and cost-saving auto-tiering

I'm a big fan of the SC Series platform. Its feature set is superior to some of the other platforms. The snapshots on SC are excellent, allowing for multiple snapshot schedules for any one system. The auto-tiering functionality intelligently moves new data to the highest performance tier and then progresses it down to less expensive tiers over time, providing cost savings for customers.

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 has good, reliable, fast storage."

"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."

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

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

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"Everything, especially the VMs inside, is pretty fast."

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

More Pure FlashArray X NVMe pros

"This solution is easy to use."

"Dell SC Series' most valuable features are performance and network facilities. We have no issues with its integration. The tool helps to visualize servers."

"The setup is straightforward."

"They have a feature called Live Migrate; it's been very, very useful."

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

"With federation, you can have multiple systems across sites. You can treat them as one, and with a live migration, volumes don't go down. You can move them from site to site, doing maintenance, and keep your environment up."

"One time, we had a drive fail and we were notified before we even saw it on the device."

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

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."

Cons

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

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

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

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

"In the next release, I would like to see real-time analytics for further insight into consumption models."

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

More Pure FlashArray X NVMe cons

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

"An issue we had was that the controller went down during an upgrade because of their upgrading the code. One side of the switch was down."

"I would like to see an integrated key manager in the controllers. Currently, it's an external product. It would be nice to have the option of having a built-in key for self-encrypting drive features."

"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?"

"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."

"While there's always room for improvement in everything, I can't really think of a specific feature of the solution that requires immediate attention."

"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"

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

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

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

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

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

"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."

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"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."

"This solution could be better priced in comparison with other vendors."

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

"The maintenance is usually pretty good. It's not like some of the others where they increase it in the fourth, fifth, or sixth years."

"The pricing of this solution is competitive."

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

"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."

"The pricing of Dell EMC Compellent is competitive."

More Dell SC Series pricing and cost advice

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

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