Compaq Infortrend manual Out-of-Band via Ethernet, What Is the “Disk Reserved Space?”

3.2Out-of-Band via Ethernet

The RAIDWatch manager software provides graphical interface to the subsystem. Before you can access the RAID system using the software manager, your must:

1.Create a reserved space on your array(s)

2.Set up the related TCP/IP configurations to enable the Ethernet port and the http service

3.FTP RAIDWatch program files to the controller IP address

What Is the “Disk Reserved Space?”

RAIDWatch and Reserved Space:

•There is no need to install the RAIDWatch program to your management computer if you access the software using the controller Ethernet port. In order to simplify the installation process, system firmware already contains important software agents.

•User’s configuration data and the manager’s main programs are kept in a small section of disk space on each data drive. The segregated disk space is called a “Disk Reserved Space.” When configuring a logical drive, firmware automatically segregates a 256MB of disk space from each of the member drives.

•Because the manager’s main program is run from the reserved space on drives, in the event of RAID controller failure, the manager interface can “failover” to a counterpart controller. Operators’ access to the system will not be interrupted.
