We recently plugged in new SSD in some of our Dell R410 systems (integrated H200 controller). The drives we put into Dell hot-plug caddies were Kingston KC100 2.5" 240Gb SATA3 (SKC100S3/240G)
We use those SSD drives in other systems like Dell R210 II and SuperMicro systems as well.
The problem is that we see a lot of the files in the disk activity with a disk latency (Response time in Resource monitor) of around 30-50ms on the Dell R410 systems, where the other systems have 0-1ms.
Surely this most likely comes down to the H200 controller, but how to process from there?
The SSDs are connected to a SAS/SATA hotplug backplane.
