Redundant Solution Requirements
The Scalar DLC Redundant (failover) solution is provided using the Microsoft Cluster service. The user has
a shared disk with the Scalar DLC database and two hosts with the installed components of Scalar DLC
software; for redundancy reasons, one host is online and the other is offline. If an error occurs and the online
host goes offline, the other host turns online immediately, so the customer even does not notice a problem
with the host. The customer engineer can repair the problem host without stopping the Scalar DLC software.
The Scalar DLC Redundant solution is based on Microsoft Cluster service. The special requirements are:
• Two PCs, each meeting the standards described in PC System Requirements
on page 5.
• Microsoft Windows 2000 Advanced Server or Windows 2003 Server installed on each PC.
• Microsoft Cluster Service installed on each PC.
• For each PC, there should be a minimum of two disk controllers. The two disk controllers do not
need to be the same type. For example, using on-board IDE and SCSI is acceptable.
• At least one external (shared) RAID disk. The disk partition should have NTFS formatting.
• RAID adapter (on each PC) to access a shared disk.

CAUTION
The Scalar DLC failover solution in a redundant configuration requires the
Windows 2000 Advanced Server or Windows 2003 Server operating system.
By default, this system is configured without password protection for network
access. So ADIC strongly urges companies using this product to use all
customary procedures to protect Scalar DLC servers from external threats.
