C Series Controller Requirements
An SSR cluster does not have any single point of failure; each node (C Series Controller) in the cluster has its own memory and disks.
All nodes in the cluster require at least two physical Ethernet ports that provide the same throughput. Bonding the Ethernet interfaces to a single IP address is required. You can accomplish this using SRC group interfaces. Data nodes require 1000Base-T (gigabit Ethernet). For client nodes 100Base-T is sufficient.
All data nodes must have equal processor power, memory space, and available bandwidth because they are tightly coupled and share data. If the overall throughput of the data nodes varies from node to node, performance degrades. Therefore, all data nodes must be of the same C Series Controller model—for example, all C4000 models.
