Eugene Hemphill - PeerSpot reviewer
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.
Brian Ricci - PeerSpot reviewer
It's constantly enhanced and has impressive reliability and data compression
The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal. I hope Dell addresses that. Everything is pricey these days anyway. It is not like the old days of Compellent. We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that.
Mark Richmond - PeerSpot reviewer
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…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Everything, especially the VMs inside, is pretty fast."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The solution is very straightforward to set up."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The latency is good."
"The high availability of the product is the most valuable feature."
"The solution is scalable."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"That's the value Dell creates; you invest less, and you get a better ROI."
"The most important aspect of Dell PowerStore in comparison to any other platform is that it helps us save costs while giving more value per GB per dollar spent. It provides an industry-leading DRR ratio."
"Overall, Dell PowerStore is very competitive in the market and able to beat the competition."
"The most valuable feature is the three-to-one data reduction."
"A particularly valuable feature is its simplicity."
"PowerStore's compression ratio is a valuable feature for our VMs because it gives us a lot back."
"The thing that I appreciate the most about Dell PowerStore is how easy it is to upgrade; the upgrade process is very simple, and I really appreciate how easy it is to connect my hosts to Dell PowerStore, as the environment automatically detects new fiber channel HBA ports for all the hosts that we connect to."
"The main feature of Dell PowerStore is its support for NVMe as well as hybrid solutions."
"We are satisfied with the stability."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The solution offers very good reliable systems and storage for our clients."
"Scalable and stable storage array."
"The servers are fast and affordable."
"The product’s quality of service guarantees the performance of each workload."
"The value we derive from using it is greater than other alternatives like HPE and Dell."
"The FlexClone feature is the solution's most valuable aspect."
 

Cons

"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The UI for this solution needs to be improved."
"The tool's pricing is higher than competitors."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Dell PowerStore does not meet the needs of a small organization; Dell has Unity which meets the entry-level or SMB segment."
"We have not seen an ROI and it would be good to have an ROI calculator made available by Dell."
"Dell PowerStore should offer more cybersecurity and warehouse data security."
"Dell PowerStore is an unfinished product compared to the HPE systems because it is relatively new."
"There are many vulnerabilities that we cannot mitigate related to the administration interface."
"The solution didn't have all of the features we needed."
"We are happy with the service in general. The only thing would be the price of the platform."
"The initial setup was a little bit cumbersome. We had a bit of an adoption process internally. It wasn't immediately straightforward on day one."
"Lenovo could have a wider variety of storage solutions in the NAS space."
"The tool's pricing is high."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"This is an expensive solution."
"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."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
 

Pricing and Cost Advice

"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."
"With VMware, we pay $300,000 annually."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"Our licensing fees are $500,000+ USD."
"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."
"In the pricing and licensing department, the product is always too expensive."
"The price of Dell EMC PowerStore could be better, it is a bit expensive."
"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."
"If we use the 500 or 1000, the licensing and pricing are reasonable. PowerStore can compete with any vendor and the price isn't that expensive."
"As compared to others, PowerStore is cheaper."
"It is expensive compared to one of its competitors."
"It is very expensive though when you get to this point of using the 3000 with a client. They will start to think about using another vendor. There are a lot of solutions similar to PowerStore in regards to networking capacity and their prices are very cheap compared to PowerStore."
"We purchased it with a five-year warranty."
"The price of the Lenovo ThinkSystem DM Series is good."
"The solution's pricing is similar to Dell and HPE."
"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 is highly-priced."
