CRAY SV1 SuperCluster Resiliency Mike Wolf I/O development SGI 41st Cray User Group Conference Minneapolis, Minnesota
Resiliency Goals Maintain cluster operations after a panic ¥ Ring Resiliency ¥ Auto-Recovery ¥ Failover
SuperCluster Resiliency Ring Resiliency ¥ Operating System resets client chip ¥ Check xxx commands resetting client chip ¥ Proxy locking ¥ Dring monitor
SuperCluster Resiliency Auto-Recovery ¥ Foundation / Monitoring ¥ User exits in check xxx commands ¥ Recovery ¥ Notification
SuperCluster Resiliency Failover ¥ NFS ¥ UDB ¥ DCE/DFS ¥BDS
Resiliency Example 1 SV1 SuperCluster Basic Building Block Mainframe 1 MPN Mainframe 2 MPN FCN MPN Mainframe 3 MPN Mainframe 4 GigaRing Ethernet SWS
