The Storage Expansion Node has the following features:
Connects directly to supported compute nodes via a PCIe 3.0 interface to the compute node's
expansion connector (See Figure 3)
Support for 12 hot-swap 2.5-inch drive, accessible via a sliding tray
Support for 6 Gbps SAS and SATA drives, both HDDs and SSDs
Based on an LSI SAS2208 6 Gbps RAID on Chip (ROC) controller
Supports RAID 0, 1, 5, 10, and 50 as standard. JBOD also supported. Optional RAID 6 and 60 with a
Features on Demand upgrade.
Optional 512 MB or 1 GB cache with cache-to-flash super capacitor offload
Note: The use of the Storage Expansion Node requires that the x240 Compute Node have both
