Default Exposed Network Services (ZFS Storage Appliance)

Language:

This table lists the default network services that are exposed by the ZFS storage appliance.

Service	Protocol	Port	Description
SSH	TCP	22	Used by the Secure Shell service to enable administrative access to the ZFS storage appliance using a CLI.
PORTMAP	TCP/UDP	111	Used by the RPC (Remote Procedure Call port mapping daemon (known as `rpcbind` or `portmap`). This service is required to support NFS version 3.
NTP	UDP	123	Used by the integrated NTP (Network Time Protocol) service (client only) to synchronize the local system clock to one or more external time sources.
HTTPS (BUI)	TCP	215	Used by the integrated HTTPS service to enable administrative access to the ZFS storage appliance over an encrypted (SSL/TLS) channel using a browser interface.
Remote Replication	TCP	216	Used by the integrated remote data replication service. Remote data replication duplicates and synchronizes projects and shares between ZFS storage appliances over an encrypted(SSL/TLS) channel.
NFS	TCP/UDP	2049 4045 various	Used by the NFS (network file system) service. NFS provides the network file sharing service. The actual number of ports depends on which version of the NFS protocol is used. NFS version3 relies upon the RPC port mapping daemon (listed above) and dynamically allocated ports to provide mounting, status, quota and related services. NFS version 4, however, relies only on TCP/2049.The NFS locking service uses TCP/4045.
iSCSI / iSNS	TCP	3260	Used by the iSCSI service that provides an IP-based storage networking protocol for linking data storage facilities. The ZFS storage appliance can be configured to share iSCSI devices (called LUNs) with networked clients.
Service Tags	TCP	6481	Used by the Oracle ServiceTag service. This is an Oracle discovery protocol used to identify servers and facilitate service requests. This service is used by products such as Oracle Enterprise Manager Ops Center to discover ZFS storage appliance software and to integrate with other Oracle automatic service solutions.
NDMP	TCP	10000	Used by the NDMP (Network Data Management Protocol) service that enables the ZFS storage appliance to participate in remotely coordinated backups.

The ZFS storage appliance also supports a variety of other services that are disabled by default including HTTP, FTP, SFTP, TFTP, WebDAV, and so on. Additional network ports might be exposed if those services are enabled after installation.
