What is the maximum number of nodes currently available in an Avamar server?

A maximum-sized Dell Avamar grid is architected for scalability and high availability. It consists of one utility node, a maximum of sixteen storage nodes for data capacity and processing, and one spare node. The spare node is configured as a hot standby to automatically take over for a failed storage node, ensuring continuous operation. The total maximum node count is the sum of these components: 1 (utility) + 16 (storage) + 1 (spare) = 18 nodes. This configuration provides the highest capacity and resiliency available in a single Avamar grid.

A. This number is too low and does not represent a standard maximum configuration for an Avamar grid.
B. This represents the maximum number of storage nodes only, excluding the essential utility node and the recommended spare node for a full configuration.
C. This represents a grid with a utility node and 16 storage nodes but omits the spare node required for a maximum high-availability configuration.

1. Dell EMC Avamar 7.5 Product Description Guide, Page 7, "Avamar data stores". It states: "An Avamar multi-node server scales from 2 to 18 nodes (1 utility node, up to 16 storage nodes, and an optional spare node)."

2. Dell EMC Avamar Data Sheet (2020), Page 3, "Specifications". It describes the architecture: "scales up to 16 nodes plus utility and spare nodes."

3. Dell Avamar 19.7 Administration Guide, Page 28, "Avamar server". It confirms the storage node limit: "A multi-node server can contain up to 16 storage nodes."
