Organizations depend on data-driven applications to accelerate innovation, improve customer experience, and maintain a competitive edge. As data volumes grow and workloads become more performance-sensitive, IT teams must keep critical applications responsive and available while operating within constrained budgets, space, power, and staffing.
They need storage that delivers predictable performance and availability, scales cost-effectively as requirements evolve, and simplifies day-to-day operations without adding infrastructure complexity.
The Solution
Lenovo ThinkSystem DE Series storage delivers the performance, availability, and efficiency organizations need to accelerate business outcomes from their most demanding data-driven applications.
From high-performance NVMe all-flash systems to cost-efficient SAS hybrid systems, the ThinkSystem DE Series is designed to support everything from high-performance databases and virtualization to analytics, AI, HPC, and bandwidth-intensive streaming workloads, while ensuring enterprise-class reliability with exceptional value.
Key Features and Benefits
- Performance for critical workloads. Deliver high IOPS, low latency, and extreme throughput to keep databases, analytics, AI, HPC, and virtualized environments responsive.
- Predictable responsiveness under pressure. Maintain consistent performance across demanding and mixed workloads, helping users and applications remain productive as utilization grows.
- Flexible flash architecture for the right economics. Choose all-flash or hybrid flash configurations that balance performance, capacity, and cost—supporting both latency-sensitive applications and high-capacity, data-intensive workloads.
- Availability and data protection for business continuity. Designed for high availability, with built-in reliability and data-integrity features that help keep critical data accessible and operations running.
- Scale without disruption. Expand storage capacity and performance as requirements evolve, helping organizations accommodate growth while avoiding unnecessary downtime or infrastructure replacement.
- Simpler, more efficient storage operations. Intuitive management tools and efficient use of rack space and power help streamline administration, optimize infrastructure utilization, and improve overall storage economics.
Available in both all-flash and hybrid flash configurations, ThinkSystem DE Series systems provide predictable performance, simplified management, and scalable capacity to help organizations extract greater value from their data while optimizing infrastructure investments. With purpose-built architecture engineered for consistent low latency and high availability, the ThinkSystem DE Series enables businesses to confidently run mission-critical workloads without compromise.
Protect Critical Data and Maintain Availability
The Lenovo ThinkSystem DE Series is engineered to protect business-critical data with a comprehensive set of security, availability, and data protection capabilities. Designed for organizations that require nonstop access to their applications and data, the ThinkSystem DE Series combines enterprise-class resilience with advanced security controls to help reduce risk, minimize downtime, and simplify administration. From protecting against drive failures to securing management access, the ThinkSystem DE Series helps ensure data remains available, protected, and accessible only to authorized users.
Key Security and Data Protection Features
- Resilient drive-level data protection. Dynamic Disk Pools (DDP) distribute data and spare capacity across drives to improve fault tolerance and accelerate rebuilds, helping reduce risk and restore protection more quickly after a drive failure.
- Centralized, role-based access control. User-level credentials, Role-Based Access Control (RBAC), and LDAP authentication help organizations centralize identity management, enforce least-privilege access, and apply consistent security policies.
- Built-in hardware redundancy. Redundant controllers, power supplies, and cooling components help eliminate single points of failure and support continuous access to critical applications and data.
- Faster recovery and stronger continuity. Snapshot and replication capabilities help protect data, accelerate recovery, and support business continuity and disaster recovery plans—reducing the potential business impact of outages or data loss.
- Encrypted management and service access. Secure Sockets Layer (SSL) and Secure Shell (SSH) encrypt administrative and authorized service communications to help prevent interception and unauthorized access.
Together, these capabilities make the Lenovo ThinkSystem DE Series a highly secure and resilient storage platform that helps organizations safeguard critical data, maintain continuous operations, and confidently support demanding business applications.
Simplified Monitoring and Management
ThinkSystem Intelligent Monitoring is a comprehensive, cloud-based digital advisor that simplifies managing and monitoring of performance, capacity, and health in Lenovo ThinkSystem DE, DG, DM, and DS Series systems through features like events, alerts, performance troubleshooting, capacity reporting, and more.
