Heterogeneous Storage with Preserved Addressing

A computing and storage system, comprising:

• a plurality of storage nodes coupled as a storage cluster, each storage node of the plurality of storage nodes having a non-volatile solid-state storage for storage of data, one storage node of the plurality of storage nodes having differing types of non-volatile solid state memory;
• the plurality of storage nodes configurable to distribute the user data and metadata associated with the user data throughout the plurality of storage nodes via erasure coding;
• one or more controllers, configurable to assign resources to a virtual server, wherein changes to the resources leave the virtual MAC address of the virtual server unchanged, wherein the one or more controllers distribute the virtual MAC address across the plurality of the storage nodes, and wherein the one or more controllers map the virtual MAC address, in a one-to-many mapping, to multiple physical MAC addresses corresponding to multiple ones of the plurality of storage nodes.
