Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The most valuable feature of this solution is its ease of use."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"It has benefited my organization because it has reduced time to insights."
"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."
"Overall stability is very good. It is a very stable solution."
"The solution offers very good reliable systems and storage for our clients."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"Ability to cluster two storages together with HA availability."
"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 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."
"The product’s quality of service guarantees the performance of each workload."
"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The tool's pricing is higher than competitors."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"It is on the expensive side."
"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 Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"The licensing model needs to be revisited. It needs to be simplified."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"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."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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."
