Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The scalability is good."
"It is the SAN backbone for our company."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"Non-disruptive upgrades: You can upgrade at anytime without worry."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"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."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"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 solution offers very good reliable systems and storage for our clients."
"Scalable and stable storage array."
"The FlexClone feature is the solution's most valuable aspect."
"We are satisfied with the stability."
"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 product’s quality of service guarantees the performance of each workload."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"The price of Pure Storage FlashArray could be better."
"The solution is not cheap."
"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."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."
"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."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"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."
"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 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."
"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."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"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."
