Two or more logical arrays having zoned drives

A plurality of storage clusters, comprising:

• a plurality of storage nodes, defining the plurality of storage clusters, the plurality of storage clusters comprising:
• a first storage cluster configurable to execute a first software;
• a second storage cluster configurable to execute a second software independent of the first storage cluster executing the first software;
• and
• the first storage cluster configurable to upgrade software independent of a software upgrade to the second storage cluster;
• and
• each of the plurality of storage nodes having membership to one of the plurality of storage clusters such that the storage nodes having the membership to the one of the plurality of storage nodes can access data of the storage cluster, via erasure coding, and wherein one of the plurality of storage nodes includes a storage controller comprising at least one zoned storage drive.

A method, comprising:

• assigning a first subset of a plurality of storage nodes as members of a first storage cluster;
• assigning a second subset of the plurality of storage nodes as members of a second storage cluster, which is independent of the first storage cluster;
• executing a first software on the first storage cluster;
• and
• executing a second software on the second storage cluster independent of the first storage cluster executing the first software, wherein the first storage cluster is configurable to upgrade software independent of a software upgrade to the second storage cluster, wherein the plurality of storage nodes includes a storage controller comprising a zoned storage drive.
