The only place I'd seen SCA is on Sun boxes :-) But then, I haven't dug into too many x86 servers. Of course, SCA is being displaced by SAS now, which has a yet > another incompatible connector.

I've used the following which might be acceptable for GNHLUG or not: Leave the OS disks on a RAID1 setup. Data on the following setup. 4 port SATA card 4 42" long SATA cables 4 short SATA extenders (from card to outside of box) external case with power supply (an old PC) 4 pin power adapter to 2 SATA power ends 4 SATA drives 4 short SATA extenders from drives to outside of case fans in case pulling air through drives There's a $20 4 port SATA card that works nice with Linux. There are IDE to SATA adapters for $20ish. They need a floppy power connector. I have a test setup at work with an external storage tower ($169). We could take up a collection for the parts & drives. I have an extra IDE to SATA adapter and $20 toward the SATA card. Maybe someone has an old 1U server chassis w/ a power supply and fans? Maybe someone has an extra IDE or SATA drive? SATA is inherently hot plug. I've read about someone adding a SATA drive to an running linux box. It reminds me of doing it with external SCSI drives. -- Ben > _______________________________________________ > gnhlug-discuss mailing list > gnhlug-discuss@mail.gnhlug.org > http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ >
