My Dell PowerEdge R630 users have reported slowdowns. Investigating did not show any issues. After a support request with Dell it was mentioned that the SSD drives I’m using are known to exhibit issues of slowdowns due to timing problems.

This has been addressed with a firmware upgrade. The drives being used are configured in a RAID10 under the PERC H730 Mini Controller

Details about the disks:

Media Type: SSD
Firmware: LPCF11XC


I will soon update to * Firmware Version 11XU *

Fixes and Enhancements
Updated SMART attribute reportiing
Improved Interface command robustness

DST Long command handling
Improved DC cycle management
