CES nodes

Cluster Export Services (CES) is used to provide SMB, NFS, or Object access to data in the IBM Storage Scale file system.

For environments with high-performance requirements, separate CES nodes are necessary. In these environments, it is suggested that a CES node runs no other workload other than the export services. For more information about the memory and CPU requirements for CES nodes, see IBM Spectrum® Scale FAQs.

Finally, the network that is used for accessing the nodes through CES protocols must run on a different physical adapter and network than the network used for IBM Storage Scale Erasure Code Edition traffic. Typically, this means that a CES node has at least two adapters, one for node-to-node access for IBM Storage Scale, and one for CES protocol access. This recommendation helps ensure that CES protocol traffic does not interfere with the IBM Storage Scale traffic, which results in better overall performance and improved cluster stability.
