Description
Supports up to two SATA M.2 drives of the following drive form factors:
• 42 mm (2242)
• 60 mm (2260)
• 80 mm (2280)
• 110 mm (22110)
Supports the following M.2 drive capacity:
• 128 GB
• 240 GB
• 480 GB (supported only when the ambient temperature is below 30°C)
Four PCIe expansion slots are available:
• Slot 1: PCIe Gen3 x4 lane in x4 slot, FH/HL
• Slot 2: PCIe Gen4 x16 lane in x16 slot, FH/HL
• Slot 3: PCIe Gen3 x4 lane in x4 slot, FH/HL
• Slot 4: PCIe Gen3 x4 lane in x8 slot, FH/HL
Notes:
1. PCIe slot 4 supports an M.2 module.
2. Slot 1 and Slot 3 in the ST250 V2 are open-end design, which means that the slots
can accept adapters with a longer edge connector than the physical length of the
slot connector. For example, if a x8 adapter is installed in the x4 slot 3 of the server,
half of the edge connector will not be connected to the slot. The adapter will still
function, however performance will be impacted.
