This section includes examples of supported multipath configurations for your J4500 array.
Note - In the examples below, the colors are used to indicate a specific host path. However, cascade (array-to-array) connections between arrays might, in some cases, be utilized by more than one host in a failover situation.
One Host, One HBA With One Array shows an example of multipath cabling using one host, one HBA and one array. This configuration supports zoned storage and failover.
Figure 4-2 One Host, One HBA With One Array
One Host, One HBA and Two Arrays shows an example of multipath cabling using one host, one HBA and two cascaded arrays. This configuration supports zoned storage and failover.
Figure 4-3 One Host, One HBA and Two Arrays
One Host, Two HBAs and Two Arrays shows an example of multipath cabling using one host, two HBAs and two cascaded arrays. This configuration supports zoned storage and failover.
Figure 4-4 One Host, Two HBAs and Two Arrays
Example Showing Two Hosts, Four HBAs and Cascaded Arrays shows an example of multipath cabling using two hosts, each with two HBAs and two cascaded arrays. This configuration supports clustering, zoned storage and failover. Each server has dual HBAs and dual paths to the cascaded arrays.
Figure 4-5 Example Showing Two Hosts, Four HBAs and Cascaded Arrays
Multiple Hosts, Multiple HBAs with Cascaded Arrays shows an example of multipath cabling using two hosts, each with two multipathed HBAs and four arrays. Both hosts have multipath connections to all four J4500's shown. If you follow any single connection, it goes from one host HBA through two cascaded J4500s and then back to the other host. This allows an HBA in either host to see all 96 drives in one cascaded SAS domain (either SAS A or B). This configuration supports zoned storage and failover. Each server has dual HBAs and dual paths to each cascaded set of arrays.
