Chapter 7. Accessing Data - Setting Up Clients
Red Hat Storage volumes can be accessed using a number of technologies:
- Native Client (see Section 7.2, “Native Client”)
- Network File System (NFS) v3 (see Section 7.3, “NFS”)
- Server Message Block (SMB) (see Section 7.4, “SMB”)
Cross Protocol Data Access
Although a Red Hat Storage trusted pool can be configured to support multiple protocols simultaneously, a single volume cannot be freely accessed by different protocols due to differences in locking semantics. The table below defines which protocols can safely access the same volume concurrently.
Table 7.1. Cross Protocol Data Access Matrix
| SMB | NFS | Native Client | Object | |
|---|---|---|---|---|
SMB | Yes | No | No | No |
NFS | No | Yes | Yes | Yes |
Native Client | No | Yes | Yes | Yes |
Object | No | Yes | Yes | Yes |
7.1. Securing Red Hat Storage Client Access
Red Hat Storage Server uses the listed ports. Ensure that firewall settings do not prevent access to these ports.
Table 7.2. TCP Port Numbers
| Port Number | Usage |
|---|---|
| 22 | For sshd used by geo-replication. |
| 111 | For rpc port mapper. |
| 139 | For netbios service. |
| 445 | For CIFS protocol. |
| 965 | For NLM. |
| 2049 | For glusterFS's NFS exports (nfsd process). |
| 24007 | For glusterd (for management). |
| 24008 | For glusterd (RDMA port for management) |
| 24009 - 24108 | For client communication with Red Hat Storage 2.0. |
| 38465 | For NFS mount protocol. |
| 38466 | For NFS mount protocol. |
| 38468 | For NFS's Lock Manager (NLM). |
| 38469 | For NFS's ACL support. |
| 39543 | For oVirt (Red Hat Storage-Console). |
| 49152 - 49251 | For client communication with Red Hat Storage 2.1 and for brick processes depending on the availability of the ports. The total number of ports required to be open depends on the total number of bricks exported on the machine. |
| 55863 | For oVirt (Red Hat Storage-Console). |
Table 7.3. TCP Port Numbers used for Object Storage (Swift)
| Port Number | Usage |
|---|---|

| 5666 | For NRPE service (required in all Red Hat Storage nodes). |
Table 7.5. UDP Port Numbers
| Port Number | Usage |
|---|---|
| 111 | For RPC Bind. |
