Memory Capacity Reporting
The system management software may report an incorrect memory capacity for your system. On
the attributes screen for the memory array, the capacity may be stated as double the actual capacity. To
correct this issue, go to support.dell.com and download and install the latest system BIOS upgrade for
your system.
Installing a PERC5i SAS RAID Controller
The optional SAS RAID controller allows for up to six hard drives in your system. When configuring your
system with a SAS RAID controller, make sure that the signal cable for drives 0 to 3 is connected to the
SAS_0 connector on the SAS RAID controller, and the cable for drives 4 and 5 is connected
to the SAS_1 connector (see Figure 1-2).
