Figure 4-38 x3690 with two 4x 2.5-inch backplanes and one IBM eXFlash 8x 1.8-inch SSD backplane
Figure 4-39 shows two 8x eXFlash backplanes. Using these two backplanes requires four
SAS cables. Figure 4-39 also shows the use of a single SATA drive.

Configurations with 20 drives
Figure 4-40 shows a full complement of drives using three 4x backplanes and one 8x eXFlash
backplane. Also, you can achieve this configuration with one 8x backplane, and one 4x and
one 8x eXFlash. Either configuration uses five SAS cables.
