Sentiment score
2.8
Customers achieved cost savings and improved efficiency with Lenovo ThinkSystem DM Series, benefiting from better data management and scalable solutions.
By opting for the gold subscription every three years, you get a free upgrade to the latest controller release.
If you wait more than seven years to buy another one, you get a return on your investment.
If you purchase storage with 300 terabytes, you can easily achieve one petabyte of effective capacity.
It's been trouble-free the entire time, with very high performance, as it has been designed and built properly.
We have seen a return on our investment in Dell PowerStore; definitely our cost per terabyte has been very good compared to some of the other vendors that we would have been using previously, and our performance benchmarks have exceeded what we were expecting.
 

Customer Service

Pure FlashArray X NVMe's technical support is praised for responsiveness, despite occasional follow-up issues, earning high customer satisfaction.
Sentiment score
6.4
Dell PowerStore's customer service is generally praised but some users report delays and challenges with complex issues and time zones.
Sentiment score
4.9
Lenovo ThinkSystem DM Series customer service experiences are mixed, with some praising it and others citing poor support.
We also had one outage where a controller of one of the products had failed and had to be replaced on-site.
Customers always have their issues resolved promptly.
Technical support is good at least through vendors, not directly with the principal.
If necessary, they will search for a specialist within their Dell network who we can approach with our questions.
I would rate the technical support of Dell PowerStore between nine and ten out of ten.
They're responsive, knowledgeable, and have a quick turnaround.
 

Scalability Issues

Sentiment score
7.1
Pure FlashArray X NVMe offers scalable storage with low latency, easy upgrades, though capacity customization and high costs are noted.
Sentiment score
7.1

It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
It hasn't broken down anytime in the last six to seven years, despite hurricanes, earthquakes, and power outages.
The solution's scalability is a ten out of ten.
It scales up and scales out both ways, and as our data keeps growing, it is very easy to just keep attaching and keep growing.
The customer likely exceeds 20,000 users globally.
Lenovo ThinkSystem DM Series is scalable, and I would rate its scalability as a seven out of ten.

When I removed all the cables, it failed over within five minutes.
There are no bugs or glitches and it doesn't crash or freeze.
I would rate the stability of Dell PowerStore as ten out of ten.
If I have sold fifty boxes, about fifty percent of them experienced failure.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell PowerStore needs enhanced VMware integration, better NAS functionality, improved scalability, stability, analytics, pricing, and support for users.
Lenovo ThinkSystem DM Series needs licensing flexibility, enhanced features, better service, and improved pricing and management.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
We mostly rely on long-term releases. We don't need the most up-to-date features, but we need a reliable environment.
If you want to delve into where your I/Os are going, the reporting might need more in-depth information to make informed decisions.
In my organization, we have had to go through two weeks with no replication, which is not very handy for our production environment.
Something needs to be done with the caching to ensure that if some issue occurs, there needs to be an ability to disable caching during maintenance to make it static, safe, and good.
Many customers have lost data while configuring it, indicating a need for improvement.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Dell PowerStore offers competitive pricing and valuable solutions, though some users seek more flexible and lower pricing options.
Lenovo ThinkSystem DM Series offers competitive pricing comparable to Dell and HPE but with complex cost calculations and optional features.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
I would give it a nine out of ten in terms of costliness.
Likely the cost is $400,000 whereas IBM may be $250,000.
Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market.
There's no need to pay for a license; it's all-inclusive.
There are extra expenses beyond the standard licensing fee for features such as replication and deduplication, which are available on demand.

Its data compression feature is the best that we have ever seen.
The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability.
The solution promotes data reduction, often meeting the compression ratio.
The PowerStore's compression ratio is even higher than the Unity system.
The deduplication part of the solution is valuable since, as a user, you get more space for less money.
One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature.

Featured Reviews

Jaehoon Oh - PeerSpot reviewer
Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Faster response and efficient data consolidation improve banking services
If I could improve Dell PowerStore in any way, I would enhance the socialization of the good skills this equipment has, improving communication with partners as the good features are inside Dell PowerStore, however, many customers don't know how powerful it is. I suggest increasing communication and giving visibility to these features inside Dell PowerStore.
CA
Complicated deployment and poor support persist, affecting overall satisfaction
The deployment process of Lenovo ThinkSystem DM Series is very complicated compared to previous GUI systems. Many customers have lost data while configuring it, indicating a need for improvement. The after-sales service is also very poor. Furthermore, it does not offer basic features like deduplication, and the service is generally considered to be very bad.
