No longer. SAS = Serial SCSI. I can barely get any high-end servers delivered without SAS anymore. The hardware is cheaper and simpler to produce than parallel. Also, you have each device on their own line - just like with SATA. A cable error no longer renders the whole 15 devices useless. - -- Peter Larsen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHpXQXHbLDna3OFD0RAuUTAJ0WYdpEBJcvl+nziH1FSuw6gSTdeQCgg/0H 947MXz4IxEyDiX+vw/am3LA= =Zl9m -----END PGP SIGNATURE----- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
