Note:  At the time of this writing, two back-end storage systems were supported as permanently directly attached: IBM DS8000 and IBM FlashSystem 900. For more information, see this IBM Support web page. 

GLYPH<SM590000> Ensure that the switches or directors are at the firmware levels that are supported by the IBM Storwize V5030 and that the port login maximums that are listed in the restriction document are not exceeded. For more information, search for “Configuration Limits and Restrictions for IBM Storwize V5000” at this IBM Knowledge Center web page. 

The suggested SAN configuration is based in a dual fabric solution. The ports on external storage systems and the IBM Storwize V5030 ports must be evenly split between the two fabrics to provide redundancy if one of the fabrics goes offline. 

GLYPH<SM590000> After the IBM Storwize V5030 and external storage systems are connected to the SAN fabrics, zoning on the switches must be configured. In each fabric, create a zone with the four IBM Storwize V5030 worldwide port names (WWPNs), two from each node canister with up to a maximum of eight WWPNs from each external storage system. 

Ports:  The IBM Storwize V5030 supports a maximum of 16 ports or WWPNs from an externally virtualized storage system. 

Figure 11-1 shows an example of how to cable devices to the SAN. Refer to this example as we describe the zoning. For this example, we used an IBM Storwize V3700 as our external storage.

GLYPH<SM590000> Create an IBM Storwize V5030/external storage zone for each storage system to be virtualized, as shown in the following examples: 

– Zone the external Storwize V3700 canister 1 port 2 with the Storwize V5030 canister 1 port 2 and canister 2 port 2 in the blue fabric.
