Environment

Our environment consisted of an IBM® System z® and a DS8300 storage server. They were connected together over a switched fabric with eight 2 Gbps FCP links.

On System z we used one LPAR (configured as mentioned above) which had access to the disks on the storage server. Figure 1 shows the storage server on the right side. In this storage server we used up to 32 disks. Details on the storage servers are described in Storage server disk usage.
