The Infrastructure Performance view displays system-level performance metrics across all systems.
The information displayed for storage systems includes:
- IOPS – Average I/O requests per second over the last 24-hour period.
- Bandwidth – System bandwidth showing average host bytes per second over the last 24-hour period.
- Utilization (Card View Only) – Average percent of time the Storage Processors (Unity XT family) or Controllers (SC and XtremIO) are busy over the last 24-hour period.
- Latency – The average time required for a packet to travel from the host to the object over the last 24-hour period. For PowerMax and VMAX, displays the response time for read and write I/O requests for the system.
- Clients (Card View Only) – Number of clients connected to the PowerScale cluster.
Performance Trend graph – Chart showing IOPS over the past 24 hours with a data point on every update (varies slightly per product type).
The System Performance information displayed for switches includes:
- System Bandwidth – Average bandwidth for the switch over the last 24-hour period.
- Utilization >= 80% – Number of ports with utilization greater than or equal to 80%4
- Congested – (Connectrix only) Number of ports with congestion
- Errors – Number of ports with errors1
- Link Reset – (Connectrix only) Number of ports with link resets
Note: The 24-hour bandwidth chart is displayed for Connectrix only.
VxRail, APEX Hybrid Cloud Services, and APEX Private Cloud Services display a 24-hour chart of CPU utilization and the 24-hour average for CPU and Memory Utilization.
PowerEdge servers show the following performance metrics:
- CPU Usage – Percentage of CPU consumed by the server
- Memory Usage – Percentage of RAM the server uses based on what is allocated
- System Board IO
- SYS Usage
- Inlet Temp – Temperature reading in Celsius
PowerProtect DD systems show the 24-hour averages for the following metrics:
- Pre-compressed Write throughput
- Pre-compressed Read throughput
- CPU Usage
- Incoming Pre-compressed Replication
- Write Streams
