StorNext Components

• Network Tools and Diagnostics In the case where issues are reported related to performance issues or connectivity issues with DLC, or issues are reported related to connectivity between SNFS clients and SNFS MDCs. For example;
  • Lower than expected throughput, or high latency on LAN Clients
  • Lower than expected file/metadata rates
  • Connectivity issues or disconnects

• Storage and SAN Tools and DiagnosticsI
• In the case where SAN client, LAN client or both types of clients are reporting performance, stability or connectivity issues. For example;
  • Lower than expected throughput, or high latency on SAN and LAN Clients
  • Lower than expected file/metadata rates
  • FSM disk connectivity issues
  • Client connectivity issues

• MDC Node Tools and Diagnostics
• When checking client connectivity issues, file operation performance issues or down file systems. For example;
  • Lower than expected file/metadata rates
  • FSM disk connectivity issues

• Client Node Tools and Diagnostics
• In the case where data path performance or stability issues are reported.
  • Lower than expected throughput or high latency on LAN Clients
  • Client connectivity issues
