What the Xeon EC5549 is
The Intel Xeon EC5549 is a quad core Jasper Forest storage processor from February 2010. It runs four Nehalem class cores at 2.533 GHz base with Turbo Boost to 2.933 GHz, with Hyper-Threading for eight threads. Cache is 8 MB on a 45 nm process. Power is rated at 85 W on LGA 1366.
The EC prefix marks the embedded storage line at standard voltage. Against the LC5528 it adds base and turbo speed at higher power. Per-SKU details beyond the task list and Intel storage documents survive in few open sources, so this page stays close to the listed values.
There is no graphics on this die. I/O comes from the storage board chipset.
Socket and motherboard compatibility
The Xeon EC5549 fits LGA 1366 with 1366 lands. Storage boards with Jasper Forest firmware boot it directly.
The socket table carries no per-codename claim for Jasper Forest, so the page shows the neutral sentence. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR3 ECC through the board design.
PCIe comes from the board chipset for storage controllers.
Cooling uses a server heatsink rated for 85 W on the 80 × 80 mm pattern.
Upgrade paths
On LGA 1366 the storage path stays within Jasper Forest on the same board. Beyond the storage platform a move to Xeon 5600 series needs a standard server board.
