Cobalt RaQ 4 User Manual 37
If RAID fails on the RaQ 4r, the system indicates the non-RAID status in three
ways:
• An email is sent to the RaQ 4 Administrator.
• Active Monitor blinks red on the Server Management screen.
• On the Server Management screen, under System Status , the Disk
Integrity (RAID) circle changes to red.
Once you replace a failed drive on a RaQ 4r and reboot the server, the system
detects the new hard disk drive. It then automatically begins to synchronize the
new hard disk drive to the existing hard disk drive so that the server will be able
to provide disk mirroring.
Site management
The RaQ 4 is designed to host multiple virtual sites. A virtual site is an individual
location on the Internet, such as www.abc.com or www.xyz.com. Each virtual
site can have a unique set of users who can send and receive email, publish Web
pages, or upload and download files through FTP. A virtual site can also provide
anonymous FTP access.
The RaQ 4 server can host a large number of IP-based virtual sites. The number
of sites depends on the amount of hard-disk-drive space available on the server,
the amount of hard-disk-drive space allocated for each site, the amount of traffic
generated on each site and the amount and complexity of the dynamic Web
content on each site (for example, ASP, CGI, PHP and others). Dynamic Web
content on an individual site induces a much heavier load on the server than does
static content.
In the Site Management section of the Server Management screen, the RaQ 4
Administrator can create and manage virtual sites hosted by the RaQ 4. A table
displays the virtual sites (if there are any) on the RaQ 4. See Figure 15.
✍
Note: During the synchronization process, the RaQ 4r cannot
provide disk mirroring but it can still serve requests.
✍
Note: A virtual site can be name-based or IP-based. If there are
several name-based virtual sites on an IP address, only one name-
based virtual site can use anonymous FTP.
