Feature Highlights

QuantaGrid D51B-2U

Full-Featured Energy Efficient 2-Socket Server

QuantaGrid D51B-2U is a general-purpose rackmount server designed for optimal performance and power efficiency. It supports up to 1.5 TB highly scalable memory capacity and up to twelve 3.5” or twenty-four 2.5” hot-swappable HDD for complex and demanding workloads, such as mail-server, database, e-commerce and high-performance computing (HPC).

Greener and More Powerful

Powered by the Intel® Xeon® processor E5-2600 v3 product family and DDR4 memory technology, the QuantaGrid D51B-2U allows owners to upgrade computing performance without overextending power consumption. With QCT’s enhanced thermal design, the server can operates under ambient temperatures as high as 40˚C. This allows owners to save unnecessary costs associated with datacenter cooling needs and achieve higher data center infrastructure efficiency (DCIE) value.

Full-Featured Design for Demanding Storage and Computing Workload

With 24 dual in-line memory (DIMM) slots, QuantaGrid D51B-2U offers non-latency support to virtualization environments that require the maximum memory capacity. In addition to twelve 3.5” or twenty-four 2.5” front-access, hot-swappable HDDs, the D51B-2U also has two optional 2.5” PCIe (NVMe) SSD bays and two optional 2.5” SATA HDD bays on the rear side for extra caching or OS support without sacrificing storage capacity.

Flexible and Scalable I/O options

QuantaGrid D51B-2U provides flexible I/O scalability for today’s diverse data center application requirements. It features OCP LAN mezzanine card solutions in addition to dual GbE or 10GbE LAN on Motherboard (LoM). With various controller vendors and different speed and technology options, customers can choose from GbE to 56GbE bandwidth, copper to fiber-optic cabling, basic Ethernet function to FCoE and ISCI SAN connectivity. The on-board SAS controller offers multiple QCT SAS mezzanine card options, with different RAID levels, and data transfer bandwidth , so customers can tailor the SAS controller for specific application needs.
