Installing a Serial ATA RAID Controller

Figure 1 shows a 3ware Serial ATA RAID controller with twelve 
ports. Up to twelve drives can be attached to this particular 
controller, through serial ATA cables. 

Figures 2 and 3 show 3ware Serial ATA RAID controllers with 8 
ports (there are two versions of the 9500S-8 controller). The earlier 
models use Pchip v1.4 and are not BBU-compatible. The more 
recent models use Pchip v1.5 and are BBU-compatible. Although 
the controllers look very similar, the location of the overall LED 
drive status indicator is different on the two versions, as shown in 
the respective figures. If you are not certain which version you 
have, you can use the 3ware CLI to determine the Pchip version 
(
