Why wouldn't any of them work just fine, if the Linux kernel contains
support for them? (No, I haven't tried any of them.)

Support for Compaq Smart* devices is directly under "Block devices"
in the kernel configuration?

< > Compaq Smart Array 5xxx support

Support for IBM ServeRAID is in the SCSI support / SCSI low-level
drivers section:

< > IBM ServeRAID support

See also <URL: ;

The HP NetRAID 3si appears to be a relabeled AMI MegaRAID 438. These
drivers are also in the SCSI low-level drivers section.

Of course Linux kernel would work at best with both controller.
Maybe Alessio wants to know if booting from SRM is possibile or not with
one of the controller listed.

I think it depends on SRM revision used by your alpha.
Which alpha would you like to use it on?
Is it your PWS?

Hi Gianluca,
for configuring one reliable web/mailserver I have solved in this way:
for booting process i have installed a 4,5 GB SCSI hard disk on my Qlogic
ISP1040 for mounting all directories except /data (it contains /var/www
and /home directory).
This directory is mounted on 2 x RAID1 9,1GB SCSI on Compaq SmartArray 2/DH
At Qlogic controller I have attached one 4GB DAT streamer for backups.
This configuration can be improved?

The SRM is updated at last version.

Sure, for my Digital Personal Workstation 500a (1 GB RAM and Matrox
Millennium PCI video card).
