We have a Unity 500 device. We are using this device to serve BI and SQL jobs.
When we restore sql files to an exported lun on storage the progress bar on MSSQL panel stuck on 100% and after a long time the job gets finished.
Long time means about 20 times more.
We tested it on the local disks of the server and the job gets finished in 5 minutes but on the storage it longs about 1 hour.
I have test many scenarios but we got the same result again and again. I have changed the windows server and reinstalled MSSQL.
I would be pleased if somebody help me with this.
