116 Understanding the IBM TotalStorage Open Software Family
referred to as the Metadata server cluster. In a SAN File System server cluster,
there is one master Metadata server and one or more subordinate Metadata
servers. Each MDS runs on a separate physical engine in the cluster. Additional
Metadata servers can be added as required if the workload grows, providing
solution scalability.
Storage volumes that store the SAN File System clients’ user data (User Pools)
are separated from storage volumes that store metadata (System Pool), as
shown in Figure 3-24 on page 115.
The Administrative server allows the SAN File System to be remotely monitored
and controlled through a Web-based user interface called the SAN File System
console. The Administ ...
