Enterprice Grade 4U 4-Socket Server

Jointly developed with Intel®, the STRATOS QSSC-S4R is powered by Intel's latest generation Xeon® processor 7500 & E7-4800 series for the expandable server segment. Designed specifically for high performance computing environments such as datacenters and large enterprises, the rack mounted QSSC-S4R features significant benefits including expandability with up to 4 processors with 40 independent processor cores, 1 Terabyte system memory via 64 memory DIMMs, 10 PCIe expansion slots, and as much as 4TB of internal storage.

Unsurpassed Computing Power

QSSC-S4R delivers unmatched flexibility with its 4U form-factor, built in support for up to 40 processor cores, and increased processor cache with the Intel® Xeon® processor 7500 & E7-4800 series. The QSSC-S4R architecture gives any IT manager the extra headroom to run simultaneous processes, greater flexibility to deploy server virtualization/consolidation, and large enterprise level capabilities to run business critical applications.

High Memory Capacity – up to 1TB

QSSC-S4R overcomes the space limitation of the 4U form factor and can accommodate up to 8 hot-swappable 8-DIMM memory riser boards. With 1TB of system memory, this is double the capacity of the previous generation in this category. From a business planning perspective, this system offers future proof capability to host virtual machines and memory-intensive HPC applications, such as engineering design automation, geophysical modeling, seismic applications, etc. From a memory-budget perspective, the system supports lower cost 4 GB DDR3 registered (with ECC) DIMMs for a total of up to 256 GB. Or alternately, QSSC-S4R supports memory DIMMs of newer DRAM technology and of larger DIMM capacity (at higher cost), such as 8GB and 16GB DDR3 registered DIMMs.

Reliable Internal Storage

QSSC-S4R supports up to eight 2.5-inch hot-swappable SAS/SATA HDDs, delivering up to 4TB of internal storage for demanding data needs. This is the ideal solution for datacenter applications, enterprise database, data warehousing analysis, streaming media, messaging platforms, etc.

I/O Riser Board and PCI Express

The QSSC-S4R I/O riser board houses the integrated Baseboard Management Controller (iBMC). It also extends server versatility by adding additional I/O capacity without using valuable PCIe slots. The system provides additional quad Gb NIC ports, one video connector, one DB9 serial port connector and support for Intel® Remote Management Module 3. In addition, QSSC-S4R supports up to 10 PCIe devices (including 4 hot-swappable), reducing server downtime, minimizing data I/O bottlenecks, and providing high bandwidth and scalability.

Redundant Cooling and Power Supply

QSSC-S4R provides high-scale system reliability and availability via redundant power supply (3+1 or 2+2) and redundant cooling (7+1) designs. Both QSSC-S4R power supply units (PSU) and the system fans are designed with hot-swap capability.

With QSSC-S4R server systems, datacenters and large enterprises can gain competitive advantage with increased IT productivity, flexibility, and systems manageability. It is an ideal solution that datacenters and large enterprises can count on now and in the future.
