Not necessarily for scalability but for a practical hardware of choice for servers intended for DHCP, NFS, OpenLDAP and DNS. Maybe for the NFS server, the SCSI HDD should be scalable for the file servers. Also, I read some article before that there is a particular IBM hardware that works best for DRBD setup. I just forgot what was that and I didn't mind it because I thought I won't be having an opportunity to use them for production use. And now, I have been instructed to research which is the best IBM server hardware for the above purposes, an IBM xSeries 345 or an IBM Blade HS20. > Bear in mind that a Blade is basically a laptop.

The initial plan is to purchase 4 or 6 server machines for the said services and it will be 2 or 3 pairs of those machines will be configured with Heartbeat and DRBD. Thanks again. GNUbie
