"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"The GUI is very easy to use and intuitive."
"The performance is very good."
"It upgrades in place which means we'll be using it well into the future."
"The deduplication and compression rates are beyond impressive."
"Its array houses our entire production environment."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases. The scale of deployment basically went from several days to a few minutes."
"It is always out of the box, and ready to use."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Its initial setup process is easy."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution's initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Lenovo ThinkSystem DE Series is simple to use"
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"Scalable and stable storage array."
"The product’s quality of service guarantees the performance of each workload."
"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."
"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."
"The price of this solution is good."
"The FlexClone feature is the solution's most valuable aspect."
"The solution offers very good reliable systems and storage for our clients."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"It is a bit expensive."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"Its performance could be faster."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"The features are limited."
"It would be useful to have structured solutions replicated to other sites."
"There could be a snapshot feature in the solution."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."
"The licensing model needs to be revisited. It needs to be simplified."
"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."
"This is an expensive solution."
