The integrated ServeRAID M5110e SAS/SATA Controller is a chip on the system board. The ServeRAID M5110 is a PCIe low-profile, half-length (MD2) form factor adapter. Both controllers have the following specifications:

Two Mini-SAS internal connectors.

6 Gbps throughput per port.

PCIe x8 2.0 host interface.

Based on the LSI SAS2208 6 Gbps ROC controller.

Supports RAID levels 0, 1, and 10.

Supports RAID levels 5 and 50 with optional M5100 Series RAID 5 upgrades (see below).

Supports RAID 6 and 60 with the optional M5100 Series RAID 6 Upgrade (see below).

Supports 512 MB battery-backed cache or 512 MB or 1 GB flash-backed cache (see below).

The ServeRAID M1115 offers a low-cost RAID 0/1/10 solution that can be upgraded to a cacheless RAID

5 with a Features-on-Demand license upgrade. It has the following specifications:

PCI Low Profile, Half-length - MD2 form factor

Two internal Mini-SAS connectors (SFF-8087)

Eight internal 6 Gbps SAS/SATA ports

6 Gbps throughput per port

533 MHz IBM PowerPC® processor with LSI SAS2008 6 Gbps RAID on Chip (ROC) controller

PCI Express 2.0 x8 host interface

Support for RAID levels 0, 1, and 10 standard; support for RAID 5 and 50 with an optional upgrade (81Y4542)

Zero Controller Cache, no battery/flash backup
