Hi,
Our of the customer has a 5230 appliance it has a serious performance problem. they are performing tape out operation for weekly full backups. and they perform that tape out process with a slp windows which is running 8 am to 5pm. their mostly tape out process happening on monday and their monday schedule backups affected badly. for example one of the vm clients backup working with a 300 mb/s ( acc enable ) when there is no performance problem, but after the tape out process same client backups working with a 20 mb/s. we are rebooting appliance and then restart affected clients backup after the reboot, its working nearly 250 or 300 mb/s. without the bandwidth the snapshot creation process takes nearly 18mins when the appliance has a bad performance. after the reboot same snapshot process takes 2 mins.
