An API object that represents a node in the cluster.

| Name | Type/Value | Description |
|------|------------|-------------|
| uid | integer | Cluster unique ID of node (read-only) |
| accept_servers | boolean (default: true) | The node only accepts new shards if `accept_servers` is `true` |
| addr | string | Internal IP address of node |
| architecture | string | Hardware architecture (read-only) |
| bigredis_storage_path | string | Flash storage path (read-only) |
| bigstore_driver | 'ibm-capi-ga1'<br />'ibm-capi-ga2'<br />'ibm-capi-ga4'<br />'speedb'<br />'rocksdb' | Bigstore driver name or none (deprecated as of Redis Software v7.2, use the [cluster object](https://redis.io/docs/latest/operate/rs/references/rest-api/objects/cluster)'s `bigstore_driver` instead) |
| bigstore_enabled | boolean | If `true`, then flash storage is enabled on this node for [Redis Flex and Auto Tiering](https://redis.io/docs/latest/operate/rs/databases/flash) databases. Configurable during [bootstrapping](https://redis.io/docs/latest/operate/rs/references/rest-api/requests/bootstrap#post-bootstrap). After bootstrapping, it is read-only. |
| bigstore_size | integer | Storage size of bigstore storage (read-only) |

| external_addr | complex object | External IP addresses of node. `GET`&nbsp;`/jsonschema` to retrieve the object's structure. |
| max_listeners | integer | Maximum number of listeners on the node |
| max_redis_forks | integer (default: -1) | Maximum number of background processes forked from shards that can exist on the node at any given time. Set to 0 for unlimited. Set to -1 to use cluster settings. |
| max_redis_servers | integer | Maximum number of shards on the node |
| max_slave_full_syncs | integer (default: -1) | Maximum number of simultaneous replica full syncs that can run at any given time. Set to 0 for unlimited. Set to -1 to use cluster settings. |
| os_family | 'rhel'<br />'ubuntu'<br />'amzn' | Operating system family (read-only) |
| os_name | string | Operating system name (read-only) |
| os_semantic_version | string | Full version number (read-only) |
| os_version | string | Installed OS version (human-readable) (read-only) |
| oss_cluster_ip_mapping | [{<br />  "key": string,<br />  "value": object<br />}, ...] | Per-node OSS cluster IP mapping by client subnet/hostname.<br />**key**: Client subnet/hostname key. Can be ipv4/ipv6 CIDR, hostname, or 'default'. |
| persistent_storage_path | string | Persistent storage path (read-only) |
| persistent_storage_size | number | Persistent storage size (bytes) (read- only) |

| rack_id | string | Rack ID where node is installed |
| recovery_path | string | Recovery files path |
| second_rack_id | string | Second rack ID where node is installed |
| shard_count | integer | Number of shards on the node (read-only) |

}, ...]
 | Versions of Redis Open Source databases supported by Redis Software on the node (read-only)<br />**db_type**: Type of database<br />**version**: Version of database |
| system_time | string | System time (UTC) (read-only) |
| total_memory | integer | Total memory of node (bytes) (read-only) |
| uptime | integer | System uptime (seconds) (read-only) |
| use_internal_ipv6 | boolean (default:&nbsp;false) | Node uses IPv6 for internal communication. Value is taken from bootstrap identity (read-only) |
