Error description
After the upgrade IBM Spectrum Protect Plus to version 10.1.9, when bandwidth throttle is enabled for a site, the replication or cloud copy jobs associated with that site will transfer data at a rate that is much slower than expected. The problem occurs specifically when multiple replication or cloud jobs run concurrently. The overall transfer throughput for a given job is reported at the end of the job log. For example: CTGGA0398 Total data replicated for job 7.31 GB; Throughput: 2.28 MB/Sec; Duration 0H:54M:49S Due to a miscalculation, the throttle rate is unnecessarily divided by the number of active jobs rather than the number of active vSnaps. The result is that all active vSnap servers in the site get throttled to a low value. | MDVREGR 10.1.8.0 5737SPLUS | IBM Spectrum Protect Plus Versions Affected: IBM Spectrum Protect Plus 10.1.9 Additional Keywords: SPP, SPPlus, TS007488465, REPLICATION, THROTTLE
Local fix
Temporarily disable the network throttle in the site settings. If this is not possible because some amount of throttling is desired, then schedule SLAs to avoid overlapping replication or cloud copy jobs within the same site.
Problem summary
**************************************************************** * USERS AFFECTED: * * IBM Spectrum Protect Plus level 10.1.9. * **************************************************************** * PROBLEM DESCRIPTION: * * See ERROR DESCRIPTION * **************************************************************** * RECOMMENDATION: * * Apply fixing level when available.

Problem conclusion
IBM Spectrum Protect Plus has been fixed. The throttle rate calculations will be based on the number of vSnap servers in a site that are actively transferring data regardless of active job count.
