Greener and More Powerful

Powered by the Intel® Xeon® processor E5-2600 v3 product family and DDR4 memory technology, the QuantaGrid D51B-1U allows owners to upgrade computing performance without overextending power consumption. With QCT’s enhanced thermal design, the server can operate 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 Virtualization Workload

With 24 dual in-line memory module (DIMM) slots, QuantaGrid D51B-1U offers non-latency support to virtualization environments that require the maximum memory capacity. The D51B-1U also has two 2.5” PCIe Non-Volatile Memory Express (NVMe) SSDs on certain configuration options (with a 2.5” PtP backplane) to accelerate cache and metadata storage for today’s demanding cloud storage and computing workload.

Flexible and Scalable I/O options

QuantaGrid D51B-1U 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 motherboards (LoM). With various controller vendors and different speed and technology options, customers can choose from 1GbE to 56GbE bandwidth, copper or fiber-optic cabling, basic Ethernet function or FCoE and ISCI SAN connectivity. The onboard SAS controller offers multiple Quanta SAS mezzanine card options with different RAID levels and data transfer bandwidth so customers can tailor the SAS controller for specific application needs.
