What the Xeon D-1557 is
The Xeon D-1557 brings Broadwell to BGA 1667 for archive nodes with DDR4. It launched in February 2016 with a 1.5 GHz base and up to 2.1 GHz boost at 45 W. Intel targets cool stores that need 12 cores with ECC on one chip.
Eighteen megabytes of cache carry file tables and indexes. The low base clock fits 12 cores in 45 W. Twenty four threads cover disk queues plus scrubbing.
There is no integrated GPU, so serial and network manage the node. The process is 14 nm. The multiplier is locked. DDR4 and DDR3 with ECC in two channels feed cores with up to 128 GB.
Buyers choose the board at order time with memory and drive tier. The 45 W rating suits packed shelves. Remote management rides on board BMC.
Socket and motherboard compatibility
The Xeon D-1557 is soldered to the board on BGA 1667 and cannot be replaced. Upgrading means replacing the board or the whole node. Boards pair the SoC with RDIMM slots for ECC and SATA for pools.
BGA 1667 boards wire PCIe, SATA, USB and LAN per server design. LGA racks cannot take this BGA chip. The LGA, PGA and BGA: CPU package types explained guide explains soldered packages.
Single socket nodes are the deployment. Growth means more BGA 1667 nodes. Service follows the server manual.
Memory, PCIe and cooling
DDR4 and DDR3 with ECC in two channels suit archive nodes. DDR4 lifts throughput for restores. Start with 32 GB for cold stores.
PCIe 3.0 with CPU lanes serves HBAs and NVMe. The SoC adds SATA and USB plus integrated LAN. Network boot trims local disks.
Cooling has no retail mount pattern because the SoC is soldered. Vendors design heatsinks for 45 W with front to back airflow. Keep filters clean.
Upgrade paths
On the same package, the Intel Xeon D-1567 lifts to 2.1 GHz base at 65 W for faster gateways with the same 12 cores. The Intel Xeon D-1571 moves to 16 cores at the same 45 W for denser racks. Both share BGA 1667 boards.
Eight core D-1540 parts suit lighter branches where listed.
Past Xeon D nodes move to later D-2100 parts. The D-1557 covers 2016 archives where 12 cores with ECC must run at 45 W.
