If you go with IDE drives it is highlu possible it is not going to work. which means, you don't have data loss if a drive fails, but downtime (depends on the server if this is critical). If you use SCSI drives and Softwareraid you can make hotswap, then if you don't have an special reason for hardware raid, you can go for software raid. - -- Clemens Schwaighofer - IT Engineer & System Administration ========================================================== TEQUILA\Japan, 6-17-2 Ginza Chuo-ku, Tokyo 104-8167, JAPAN Tel: +81-(0)3-3545-7703 Fax: +81-(0)3-3545-7343 http://www.tequila.co.jp ========================================================== -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFAa6EqjBz/yQjBxz8RApbuAKDf2q472lXPznFHPkpQ56dSLRkKJwCdGHWm agCc+RjOofOQk3aNaZRB4GY= =w1b7 -----END PGP SIGNATURE-----
