Ports Used by the FluidFS Cluster
You might need to adjust your firewall settings to allow traffic on the network ports used by the FluidFS cluster. For a list of ports used by
the FluidFS cluster, see the Dell EMC Fluid File System Support Matrix.
FluidFS System Management for FS Series
Appliances
This section contains information about basic FluidFS cluster system management. These tasks are performed using the Storage Manager
Client.
NAS Access
FluidFS supports the Unicode /UTF-8 encoding, allowing concurrent access from any UTF-8 compatible client. All NAS interfaces expect
UTF-8 characters for file, folder/directory, share, and other names.
Consequently, all names are internally maintained and managed in UTF-8 format. While individual file and directory names are each limited
to 255 bytes, the number of characters might be further limited, due to the variable-width nature of the UTF-8 encoding.
Management Access
Management data items, such as volume names, share names, directory names, user names, description fields, and so on, are all
maintained in UTF-8 format.
For CLI access, UTF-8 terminal applications, such as XTERM, should be used. Terminal applications that do not support UTF-8 characters,
such as KTERM, are not recommended.
Seamless Session Failover
Seamless session failover decreases the client connection timeout. With seamless session failover, you can easily move a connection
between cluster controllers. This feature sends a connection reset packet to the dropped client to immediately terminate a session with a
failed controller. The client will then reestablish the session with the new controller and the connection will resume.
Using the Storage Manager Client or CLI to Connect to the
FluidFS Cluster
As a storage administrator, you can use either the Storage Manager Client or command-line interface (CLI) to connect to and manage the
FluidFS cluster. By default, the FluidFS cluster is accessed through the client network.
Connect to the FluidFS Cluster Using the Storage Manager Client
Log in to the Storage Manager Client to manage the FluidFS cluster.
Prerequisites
The Storage Manager user account must have the Administrator privilege to view, manage, or add FluidFS clusters in the Storage
Manager Client.
Steps
1. Start the Storage Manager Client application. The Storage Manager Client opens.
