Monitor storage devices
Use the system console to monitor storage devices in your system. You must be assigned the Hardware administration role with permission to View all hardware resources (Read-only) to perform these steps. By monitoring your storage devices, you can view various details such as associated events and jobs, firmware levels, status, capacity, and usage and allocation of disks and volumes.
Procedure
- Click Hardware > Storage Devices.
- Select a storage device and monitor its details:
- Events: Number of events that are associated with the device.
- Jobs: Specifies the pending and started jobs that are associated with the device.
- Type: Specifies the type of storage device.
- Firmware: Specifies the firmware release level.
- Status: Specifies the availability status of the device.
- Capacity: Specifies the capacity of the device. This information is displayed only for the storage controller and includes the total space and the percentage of space used.
- Location: Specifies the physical location of the device in the system.
- Temperature: Specifies the temperature information for the device.
- Physical cores: Specifies the percentage in a graph of CPU utilization and CPU allocation.
- Disk Drives: Specifies a list of disk drives their information, including location, state, capacity, and type.
- Operating system volumes: Specifies the operating system volumes.
- Storage volumes: Specifies a list of storage volumes that are associated with the device, including their name, size, and state.
In a VMware environment, PureApplication System allocates Virtual Machine File System (VMFS) volumes on a cloud group basis as needed. VMFS is a high-performance file system that is optimized for storing virtual machines. The system first searches for a storage controller that has at least 1.8 TB of free capacity and an average latency less than 50 ms for the new VMFS storage volume. If no storage controller with such latency exists, the request to create a disk or volume fails.
For each storage controller that has an acceptable average latency, the system searches for an existing storage volume on the controller that contains sufficient free capacity for the new disk or volume. Otherwise, a new storage volume is created. After the VMFS storage volume is identified, the disk or volume is placed in the VMFS storage volume.
When a cloud group is deleted, all remaining VMFS storage volumes for the cloud group are released. As disks or volumes are released, the system attempts to free unused storage volumes while it retains excessive capacity to avoid creating and deleting storage volume cycles unnecessarily. Deleting a 1.8 TB storage volume (when a disk or volume is deleted) to create a new 1.8 TB storage volume is an example of a cycle that is unnecessarily deleted.
- LUNs: Specifies the total and pending number of logical unit numbers (LUNs).
- Storage controller ports: Specifies information about the number of total ports, availability, the device state, identifier and speed, and the corresponding worldwide port name.
- Storage node statistics: Specifies the input and output statistics for the storage node, including bytes, latency, and number of messages.
- LEDs: Specifies information about the LEDs for the device.
