What the Xeon D-1581 is
The Xeon D-1581 brings Broadwell to BGA 1667 for storage servers with DDR4. It launched in February 2016 with a 1.8 GHz base and up to 2.4 GHz boost at 65 W. Intel targets warm stores that need 16 cores with ECC on one chip.
Twenty four megabytes of cache carry file tables and dedupe metadata. The higher base clock trims request latency over slower siblings. Thirty two threads cover disk queues plus replication.
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 size and drive tier. The 65 W rating suits 1U heads with shared airflow. Quick Assist style crypto units help encrypted stores where licensed.
Socket and motherboard compatibility
The Xeon D-1581 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 plus NVMe 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 storage nodes with many disks. DDR4 at 2133 MT/s lifts file throughput. Start with 64 GB for warm stores.
PCIe 3.0 with CPU lanes serves HBAs and NVMe per board layout. The SoC adds 6 SATA ports 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 65 W with front to back airflow. Keep filters clean.
Upgrade paths
On the same package, the Intel Xeon D-1587 trims base to 1.7 GHz with the same 16 cores for similar stores. The Intel Xeon D-1571 drops to 1.3 GHz base at 45 W for cooler aisles. Both share BGA 1667 boards.
Twelve core D-1557 suits lighter archives where listed.
Past Xeon D nodes move to later D-2100 parts. The D-1581 covers 2016 stores where 16 cores at 1.8 GHz must run at 65 W.
