NAS supports up to four Fibre Channel ports per server, multiple FC switches, and multiported SAN disks. iSCSI arrays are also supported. The following diagrams show some sample cluster configurations using these components. In the HP Scalable NAS File Serving Software administration guide 35 - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 36
diagrams, the FC fabric cloud can include additional FC switches that are not managed by HP Scalable NAS. Single FC port, single FC switch, single FC fabric This is the simplest configuration. Each server has a single FC port connected to an FC switch managed by the cluster. The SAN includes two - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 37
are connected to the second switch. The cluster also includes two RAID arrays, which contain multiported disks. If a managed FC switch fails, the servers connected to the other switch will survive and access to storage will be maintained. HP Scalable NAS File Serving Software administration guide 37 - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 38
switches, single FC fabric This example uses multipath I/O to eliminate single points of failure. The fabric includes two FC switches managed by the cluster. Each server has two FC ports; the first FC port connects to the first FC switch and the second FC port connects to the second FC switch - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 39
the previous example, but also includes dual FC fabrics, with a cluster-managed FC switch in each fabric. If one of the fabrics should fail, the servers can access the storage via the other fabric. HP Scalable NAS File Serving Software administration guide 39 - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 40
iSCSI configuration This example shows an iSCSI configuration. The iSCSI initiator is installed on each server. Ideally, a separate network should be used for connections to the iSCSI storage arrays. 40 Introduction - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 41
be aware of the following when managing HP Scalable NAS. Network operations • Normal operation of the cluster depends on a reliable network hostname resolution service. If the hostname lookup facility becomes unreliable, this can cause reliability problems for the running cluster. Therefore, you - HP ProLiant DL380G5-WSS | 3.7.0 HP StorageWorks HP Scalable NAS File Serving Sof - Page 42
