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

"The database workloads are pretty fast because I frequently move data from here to there."

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

"The solution uses newer technology for deduplication and compression."

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

"The most valuable feature of this solution is reliability."

"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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"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."

More Pure FlashArray X NVMe pros

"The most valuable feature is the speed for the end-user."

"It has been one of the most stable products in our data center."

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

"The performance benefits weren't surprising, we expected that. What we didn't expect were the densification benefits that we got out of going all-flash. We're able to put more applications on the arrays because of how all-flash performs. The way some of the application profiles have responded to all-flash has been really pleasing."

"The most valuable features are the with back-end dedupe, and the thin nodes. For a 20TB or 60TB, we're using almost a one-to-two ratio."

"Connecting it up, you can run it within a few hours."

"It's very scalable, especially with federation. If you outgrow the number of spindles that a unit can support, depending on the model, you can go into federation."

"The solution is stable."

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

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

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

"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."

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

"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."

"In terms of what needs improvement, the dashboard and management could be simplified."

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

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

More Pure FlashArray X NVMe cons

"Some menus aren't so intuitive."

"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."

"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms. What I have said, constantly, to my partners at Dell EMC is that the clear articulation of the path is really important to us. In that vein, what I'd also like to see is, with the migration strategy that's built into this product, a lot more attention paid to Dell's - in particular - legacy platforms and how we get from some of our legacy EMC platforms onto this platform with a straight-through migration and scaling strategy, not host-based migrations and not piecemeal... Dell EMC would do well to focus more on my ability to skip a generation, rather than having me take individual hops because I can't greenfield my way into a software-defined data center fast enough. This journey of multiple hops is not helpful."

"Dell could improve the upgrading process."

"The lack of reporting would be the main issue."

"In terms of additional features, I would like to see some kind of I/O meter, to indicate what we are using in terms of performance. I would like to see automation with that, where it would give me the trends. I want to know those things easily, to help me know where issues are going to occur."

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

"One option I would like to see is, when you're up on the view-screen, to be able to incorporate getting to what HPE call the iLO, the Integrated Lights-Out. To be able to get that instead of having to go back and trying to find IP addresses and re-institute those would be good. It would be good to be able to that put on the initial splash screen."

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

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

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

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

"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."

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

"The licensing is on a yearly basis."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"Pricing depends on varying life cycles."

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

"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."

"We have found the solution to be affordable."

"The pricing of Dell EMC Compellent is competitive."

"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."

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."
