Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."At this point, I don't know anything that they could provide in a better way."
"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The GUI is very easy to use and intuitive."
"The performance of the storage is just unbelievable."
"Because of the encryption, we have different storage and the encryption can go over both."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"Ability to cluster two storages together with HA availability."
"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 product’s quality of service guarantees the performance of each workload."
"The price of this solution is good."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"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."
"We are satisfied with the stability."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"The price could be better."
"The technical support is okay, but could be improved."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"Going forward, don't complicate things for the customers."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"CIFS and SMB Shares cannot be mounted directly."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"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."
"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."
"The licensing model needs to be revisited. It needs to be simplified."
"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."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
