TotalStorageDS Extent Pool
The TotalStorage Extent Pool attributes provide information about the extent pools in a TotalStorageDS storage facility.
Allocated Extents: The total number of real allocated extents in the pool.
Avg Read Op Rate: The average read operations per second to all ranks in the extent pool.
Avg Read Resp Time: The average read response time (in milliseconds) to all ranks in the extent pool.
Avg Write Op Rate: The average number of write operations per second to all ranks in the extent pool.
Avg Write Resp Time: The average write response time (in milliseconds) to all ranks in the extent pool.
Dyn Reloc Src Extents: The total number of extents used as source for dynamic relocation.
Dyn Reloc Tgt Extents: The total number of extents used as the target for dynamic relocation.
Dyn Reloc Tgt Extents: The total number of extents used as the target for dynamic relocation.
Extent Pool ID: The identifier of the extent pool.
Managed System: The internal node name used to identify the system from which this row of data was obtained.
Max Read Op Rate: The maximum read operations per second to any rank in the extent pool.
Max Read Resp Time: The maximum read response time (in milliseconds) to any rank in the extent pool.
Max Write Op Rate: The maximum number of write operations per second to any rank in the extent pool.
Max Write Resp Time: The maximum write response time (in milliseconds) to any rank in the extent pool.
Number of arrays with problems: The number of arrays with error conditions of Raid Degraded (one or more array members need rebuilding), DDM Throttling (a near-line DDM in the array is throttling performance due to temperature or workload), or RPM Exception (a DDM with an slower RPM than the normal array DDMs is a member of the array as a result of a sparing action).
Pool Type: The extent pool type, either CKD (Count Key Data) or FB (Fixed Block).
Pool Utilization: The percentage of the total extents in the pool that are currently allocated.
Real Extents Converted: The total number of real extents converted in the extent pool.
Real Extents: The total number of real extents in the extent pool.
Real Pool Capacity: The total real capacity (in GB) of the extent pool.
SSD Ranks: The status of solid state devices in the extent pool, including All, None, and Mixed (both SSD and non-SSD ranks).
Storage Facility ID: The storage facility identifier for the device (Type-Model-Serial Number).
Storage Facility Serial Number: The storage facility serial number of the device.
Time Stamp: The date and time associated with this row of data.
Total Read Operations: The total read operations to all ranks in the extent pool.
Total Write Operations: The total number of write operations to all ranks in the extent pool.
Virt Extents Converted: The total number of virtual extents converted in the extent pool.
Virtual Extents: The total number of virtual extents in the extent pool.
Virtual Pool Capacity: The total virtual capacity (in gigabytes) of the extent pool.
