i have a new installation of BE 15 FP3 in CAS MMS environmnet with (ODBC connection eror ...) problem.
but my main concern for now is it's take around 30-40 minutes for every job to start backup proccess, specially for jobs tageted on deduplication storage and opt-duplicate jobs.
job starts but it will hang at "Loading Media" for about 40+ minutes .
i've checked server is not using more that 20~30% of resource (CPU-RAM-Network-Disk..).
my installation is a CAS (VM) and 2 MMS (DL380 G8) with windows server 2012 R2 ,each mms have aound 12 TB of disk (Raid 50 Array with 10K disks).
Number of Concourunt jobs on deduplication disks is set to 6.
each server have at leaste 2 Gb/s ethernet connectivity.
i wonder what could be the cause of this delay?
