Thanks for that link - they look interesting.

2 LSI 6295 with BBU, 4 10k SAS drives, the mounting bays - that's around
2500 EUR.

For now the system uses two local SATA-Drives with software-raid1 and
this setup is more than enough performance. Is there really no cheaper
solution to get DRBD up and running with the same perfomance than a
local Software-Raid1?
