Important Note: This configuration can be extended up to four drives provided the host system can

support four dual SAs HBAs.

the Library must contain only LT04 media for proper operations.

Important Note: Heterogeneous configurations containing LT03 drives are not supported

One host, one Fibre Channel switch and one PowerVault™ library configured with one LT04

Fibre Channel and one LT05 Fibre Channel drive
