Print Server Tips and Techniques
Consider the following tips and techniques when configuring print servers.
■
Using a server’s built-in SCSI port (if compatible) to minimize cost will result in
satisfactory print server performance in most environments, even if the SCSI port
does not operate at full Ultra320 or Ultra160 speeds.
■
Data protection can be provided via host-based software volume management
software using the operating system’s volume manager or a third-party volume
manager. The recommended configurations will provide RAS similar to a single
controller RAID array.
■
Each server must be connected to a different SCSI bus when using the
recommended large configuration.
■
When adding a second server, one RAID 1 logical drive can be reassigned to the
second server by moving its drives to the second SCSI bus if the server operating
systems and volume managers are compatible.
