Product Features
Technical Overview
At its core, the SR950 leverages the Intel C624 chipset to manage eight second-generation Xeon Platinum 8260 processors. Each processor provides 24 cores and 35.75MB of cache, delivering a total of 192 cores for parallel processing. The memory subsystem uses TruDDR4 technology with error-correcting code (ECC) to maintain data integrity under heavy loads.
Storage is handled by two 930-16i controllers that support both 12Gb/s SAS and Serial ATA/600 drives. The RAID controller offers levels 0, 1, 5, 6, 10, 50, and 60 for flexible data protection and performance. Expansion is facilitated through 17 slots, accommodating additional networking, storage, or accelerator cards as needed.
This section brings together practical product details such as Number of Processors Supported, Number of Processors Installed, Processor Type, Chipset Manufacturer, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

Deployment / Use Cases
This server is tailored for large-scale enterprise and data center deployments where compute density and reliability are paramount. Its multi-processor design and extensive memory support make it suitable for virtualized environments, allowing consolidation of numerous virtual machines onto a single physical host.
In database applications, the SR950's high core count and fast storage controllers accelerate transaction processing and analytics. It also serves well in high-performance computing clusters, scientific simulations, and financial modeling, where parallel processing capabilities reduce time-to-results.
Virtualization Host
Support for major hypervisors and high memory capacity enables efficient VM consolidation, reducing physical server footprint and management overhead.
Database Server
The combination of multiple processors, large cache, and RAID-protected storage ensures fast query performance and data integrity for critical databases.
Physical Profile
Designed for standard 19-inch racks, the SR950 occupies 4U of vertical space with dimensions of 6.90" height, 17.60" width, and 33.50" depth. Its weight of approximately 129.41 pounds reflects the robust construction and high component density. The rack-mount form factor includes integrated rails for secure installation, and the front-accessible drive bays simplify maintenance in crowded data center environments.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 4U, 17.60" (447.04 mm), 33.50" (850.90 mm), 129.41 lb (58700 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
