Description
Lenovo ThinkSystem SR950 is designed for your most demanding, mission-critical workloads, such as in-memory databases, large transactional databases, batch and real-time analytics, ERP, CRM, and virtualized server workloads.
The powerful 4U ThinkSystem SR950 can grow from two to eight second-generation Intel® Xeon® Processor Scalable family CPUs, delivering up to 36% total performance improvement over the first generation processor.* The modular design of SR950 speeds upgrades and servicing with easy front and rear access to all major subsystems, to keep your data flowing.
Reliability Redefined
Core business workloads require systems that can provide continuous availability. In the past, to get high availability, customers often had to sacrifice performance with expensive proprietary platforms that locked them into inflexible ecosystems.
The modular ThinkSystem SR950 is designed from the ground up to deliver “always-on” reliability on an x86 platform. Featuring multiple levels of resiliency to protect data, the ThinkSystem SR950 is built to ensure continuous operation:
- Predictive Failure Analysis alerts administrators to impending failure of processors, memory, PSUs, system fans, adapter slots, HDDs/SSDs, and VRMs, allowing servicers to schedule planned downtime, rather than reacting to sudden failure
- Independently-powered light path diagnostic LEDs light up beside the failing component for instant identification, enabling fast servicing and reduced downtime
- Machine Check Architecture (MCA) Recovery provides OS-layer assisted recovery from uncorrectable data errors, to prevent system reset
- Adaptive Double Device Data Correction protects the system from memory errors while effecting a repair
- Fatal Error Handling enables override of application shutdown by setting a custom handler of fatal errors
These are only a few of the many technologies that deliver the exceptional system availability and continuous application performance needed for mission-critical core applications. In addition, Lenovo servers continue to be the industry’s #1 most reliable
