BE Directors (DA) analyze view (Diagnostic and Historical)
Analyze views provide an in-depth exploration of storage system data across various collection ranges.
| Attribute | Description |
|---|---|
| Name | The ID of each backend director |
| % Busy | The percentage of time that a director is busy |
| IOs/sec | The number of I/O operations per-second commands to the disk |
| Reqs/sec | The number of data transfers that occur between the director and the cache. An I/O may require multiple requests depending on I/O size, alignment or both. For writes the request counter is incremented at the time that the write pending flag is removed from the cache slot. If multiple DAs are involved in the I/O operation (such as RAID 1), the request count may not reconcile with the I/O count and I/O size. |
| MBs Read/sec | The average size of host MBs read (per second) by the director |
| MBs Written/sec | The average size of host MBs written (per second) by the director |
