They are awfully nice little boxes; but there is one other flaw - there's a bug in Solaris 8 with respect to clock management on the X1 and Blade boxes. Even with (x)ntpd running, the system clock will occasionally (on the order of once or twice a day) jump by 20 or more seconds out of sync; and stay that way for a random time period. (One company I work with has a farm of 30 X1s and a distributed app where time synconization is = critical. Their boxes usually stay out of sync for about 5 to 20 minutes before ntpd slams them back where they belong.) (No, it isn't a configuration problem or lack of system patch. Sun are apparently aware of the problem and working on a patch upgrade.) Oh, and you have to make sure your X1 farm is in a properly air-conditioned environment; otherwise they tend to start to overheat and automatically = shut themselves down. (I would expect the same requirement of any equivalently powerful 1U box...) -Pat GnuPG/PGP key 9DC60D6CB0FCC2E3 at search.keyserver.net Fingerprint: A241 AADC 5AB8 1A36 08FF 7168 9DC6 0D6C B0FC C2E3 --==========2279407794========== Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: For info see http://www.gnupg.org iEYEARECAAYFAjtM2rMACgkQncYNbLD8wuNoBACfcmLIoLGqjEEQxPmWG0bjqCcG G9UAmwfP/m4dGiWr7krtP6CsVuDRmti3 =Im48 -----END PGP SIGNATURE----- --==========2279407794==========-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
