Intro

The S3 protocol is delivered via gateways to the web object scaler (WOS) nodes. Currently there are 2 WOS nodes and 5 gateway nodes in production.

WOS

Each WOS nodes has 2 10 GE interfaces. Currently only a single 10 GE connection is active. IP adresses and cabling have been reserved for connecting the second interfaces (link aggregration). The 2 WOS nodes are logically in 2 different zones though physically they are in the same rack. 

wos-2-a 141.52.220.80
wos-2-b 141.52.220.81 (not active)
wos-3-a 141.52.220.82
wos-3-b 141.52.220.83 (not active)

S3 Gateways

The S3 gateway is installed on 5 servers: 

141.52.220.75
141.52.220.76
141.52.220.77
141.52.220.78
141.52.220.79

Node 141.52.220.79 is the management node, where several administration tools are installed:

  • accesskeyctl
  • adminctl
  • configctl

Administrators can manage and monitor the activities on WOS Access S3 platform through the Web UI.

Managing credentials

The tool for managing credentials is DDN's accesskeyctl. The following actions are possible:

List all existing keys: 

[root@node31 ~]# accesskeyctl -l

      Access Key                         Secret Key                                     UUID                         Tag          Enabled

Generate a new pair of keys: 

[root@node31 ~]# accesskeyctl -g tag

Credentials generated with tag 'tag':
  accessKey='AKIA2UBKM1AODG1L178D'
  secretKey='+4urJWrORF1EEFdQz9hmlLO6ptV5bxHAALiSuq8b'

Enable/disable credentials: 

[root@node31 ~]# accesskeyctl --disable AKIA2UBKM1AODG1L178D
Credentials for AccessKey 'AKIA2UBKM1AODG1L178D' have been disabled.

Regenerate secret key associated with an access key: 

[root@node31 ~]# accesskeyctl --regenerate AKIA2UBKM1AODG1L178D
SecretKey for Credentials with AccessKey 'AKIA2UBKM1AODG1L178D' has been regenerated, new SecretKey is 'fgPanwW9BiVY1uFWdh8ag6DtuwJXW6mvem8cNFwl'.

Managing cluster services

The adminctl tool helps user manage the cluster services. 

[root@node31 ~]# adminctl --status
