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.

Reliable and fast servers with good support
We use on-premise servers with Lenovo ThinkSystem. We set up Hyper-V and load multiple types of servers including a domain controller, a SQL Server, and application servers The solution provides fast servers that are reasonably priced. We set up RAID ten to ensure drive redundancy, leading to…
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

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"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."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable feature of this solution is reliability."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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."
"Scalable and stable storage array."
"The FlexClone feature is the solution's most valuable aspect."
"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."
"The value we derive from using it is greater than other alternatives like HPE and Dell."
"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."
"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."
"The price of this solution is good."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"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

"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"Maybe the price can be reduced since the solution is very expensive."
"The software layer has to improve."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"The tool's portfolio is minimal. It is expensive."
"There might be improvements needed in drive throughput as disk speed has been a limitation on Windows servers."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"Lenovo could have a wider variety of storage solutions in the NAS space."
"The tool's pricing is high."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"This is an expensive solution."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"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 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."
"Our licensing fees are $500,000+ USD."
"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 pay approximately $50,000 USD per year in licensing fees."
"As far as the licensing costs, everything is included in the license."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"The price of the Lenovo ThinkSystem DM Series is good."
"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
"The solution's pricing is similar to Dell and HPE."
"The solution is highly-priced."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
