Automatic hot standby, true, functional hot pluggable everything, full redundancy, IP switchover, self monitoring and error recovery, etc. We support RAID-0, RAID-1, RAID 5. Currently only up to 45 drives per array, but that will change too. While the system is NOT a classic Fault Tolerant, it allows you to build various servers theat will provide uninterrupted service with single component failure ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 503.799.2313 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
