cannot be mixed with SAS disk on the same adapter. The adapter does not have write cache. Figure 65
shows the PCIe3 LP 4 x8 SAS Port Adapter.
A maximum of four DVD or tape drives can be attached per adapter by using four AE1 cables (FC
ECBY). A maximum of eight DVD or tape drives can be attached by using four YE1 cables (ECBZ).
Externally attached devices are designed to run at a maximum data rate of 6 Gbps for SAS tape devices.
Important: For more information, see the SAS RAID controllers for AIX, SAS RAID controllers for IBM i,
or SAS RAID controllers for Linux topics for more information and important considerations for
multi-initiator and high availability or dual storage IOA configurations.
Figure 65 shows the adapter. The connector plug (A) is installed in an empty port and prevents damage
to that port whenever a cable for the adjacent port connectors is plugged-in or removed.
