Internal disk storage options
The x440 server has two 2.5-inch hot-swap drive bays accessible from the front of the blade server
(Figure 2). These bays are connected to the integrated 4-port LSI SAS2004 6 Gbps SAS/SATA
RAID-on-Chip (ROC) controller.
The integrated LSI SAS2004 ROC has the following features:
Four-port controller with 6 Gbps throughput per port

PCIe x4 Gen 2 host interface

Two SAS ports routed internally to the two hot-swap drive bays

Supports RAID levels 0 (Integrated Striping), 1 (Integrated Mirroring), 10 (Integrated Mirroring and

Striping), and 1E (Integrated Mirroring Enhanced)
