link HP MicroServer Gen8 Hot-Swap Disk Limitation

I bought a HP MicroServer Gen8 G1610T and installed an Adaptec RAID card and hard drives which all supported hot-swap. I wanted to know what the limitation was with this server as I've hot-swapped Seagate SATA desktop drives in numerous QNAP NAS' and it always worked as expected. Turns out it's the disk caddies.
