Author infoRatingReview Summary
Service manager at Crescent Technologies1.0I primarily use the Lenovo ThinkSystem DM Series for storage in a sandbox environment. While the snapshot feature is valuable, the lack of deduplication limits efficiency. Deployment is complex, with poor after-sales service, offering no measurable ROI benefits.
Chief Technology Officer at Next Level Communications4.5I use Lenovo ThinkSystem for on-premise servers with Hyper-V, setting up various server types like SQL and application servers. They are fast and affordable with RAID 10 for redundancy, though drive throughput could be improved. They outperform the previous HP servers we used.
