Manage storage performance

You can manage storage performance metrics by cluster, host, or disk.

Monitor storage cluster performance

On the top navigation bar, click Storage, and then select Performance Monitoring from the navigation pane.

Monitor host performance

1. On the top navigation bar, click Storage, and then select Performance Monitoring from the navigation pane.

2. Click the Hosts tab.

3. Select a host from the Host list to view performance data about that host.

Monitor disk performance

1. On the top navigation bar, click Storage, and then select Performance Monitoring from the navigation pane.

2. Click the Disks tab.

3. Click the name of a disk in normal state to view its performance data, including IOPS, I/O throughput, latency, and disk capacity usage.

Filter disk information

1. On the top navigation bar, click Storage, and then select Performance Monitoring from the navigation pane.

2. Click the Disks tab.

3. Click Filter.

4. Configure the filter criteria, and then click OK.

Export disk information

1. On the top navigation bar, click Storage, and then select Performance Monitoring from the navigation pane.

2. Click the Disks tab.

3. Click Export.

4. Select a file format, and then click OK.

Parameters

Storage cluster performance metrics

• IOPS: The number of reads/writes processed per second by the storage cluster for the most recent 30 minutes. To view IOPS data at a particular time in point, hover over the curve.

• Read: Represents the read IOPS.

• Write: Represents the write IOPS.

• Restore: Represents the IOPS to retrieve backup data for data restoration.

• I/O Throughput: Displays the storage cluster I/O throughput data for the most recent 30 minutes. To view IOPS data at a particular time in point, hover over the curve.

• Read: Represents the read throughput.

• Write: Represents the write throughput.

• Restore: Represents the throughput to retrieve backup data for data restoration.

Host performance metrics

• IOPS: Displays the average number of data disk reads/writes processed per second by the host for the most recent 30 minutes. To view the data at a particular time in point, hover over the curve.

• I/O Throughput: Displays the average data disk I/O throughput data on the host for the most recent 30 minutes. To view the data at a particular time in point, hover over the curve.

• CPU Usage: Displays the CPU usage data on the host for the most recent 30 minutes. To view the data at a particular time in point, hover over the curve.

• Memory Usage: Displays the memory usage data on the host for the most recent 30 minutes, including used memory and free memory. To view the data at a particular time in point, hover over the curve.

• Disk Capacity: Displays data about used capacity and free capacity of the disk for the most recent 30 minutes. To view the data at a particular time in point, hover over the curve.

• Latency: Displays the average disk read and write latency data for the most recent 30 minutes. To view the data at a particular time in point, hover over the curve.

• Disk Load: Displays the disk load data (in ms) for the most recent 30 minutes. To view the data at a particular time in point, hover over the curve. A higher value represents a heavier storage load.
