Perform Post-Setup Tasks
Complete the deployment by performing these post-setup tasks. All tasks are optional.
Add DNS Records for the FluidFS Cluster
If clients access the FluidFS cluster by name, add an entry in the DNS server that associates the FluidFS cluster name to the FluidFS
cluster client VIPs.
• If you are in a routed client network and using multiple client VIPs, add all client VIPs to the DNS server and associate them with
the same FluidFS cluster name (set up round-robin DNS).
• If you are using Active Directory, the DNS servers must be the same DNS servers that the Active Directory domain controllers
use.
Enabling Secured Management
By default, all FluidFS cluster management ports are open on all subnets, along with the other ports needed for client access (SMB/
NFS), replication, and NDMP. Secured management, when enabled, exclusively limits all management trac to one specic subnet.
The subnet on which secured management is enabled also has the necessary ports open for client access, replication, and NDMP
trac. Other subnets will not have any of the management ports listening on them, making them available only for client access,
replication, and NDMP trac. This restriction prevents users on client (data) access subnets from accessing any FluidFS cluster
management functions.
In FluidFS, the ports listed in the following table do not participate in SMB/NFS communication, but are exposed on the client
network by default. Enabling secured management allows you to expose the management ports on a management subnet only.
Service
Port
Web Services 80
Secure Web Services 443
FTP 44421
FTP (Passive) 44430–44439
FTPS 990
SSH 22
Dell Storage Manager communication 35451
Secured management can be enabled only after the system is deployed. To make a subnet secure:
• The subnet must exist prior to enabling the secured management feature.
• The subnet can reside on the client network (subnet-level isolation of management trac) or the LOM (Lights Out
Management) Ethernet port (physical isolation of management trac). The LOM Ethernet port is located on the lower-right side
of the back panel of a NAS controller.
• You must log in from this subnet.
