Pathlight VX Components
The Pathlight VX contains the following components:
•MS
• SNC (either 1 or 2 FC blades)
1
• FC switch (in High-Performance configurations)
• RAID storage disk
• Pathlight VX-450 uses 2 AX100SC enclosures as the RAID.
• Pathlight VX-650 uses CX300 enclosures as the RAID.
Each Pathlight VX contains one MS and one SNC. Together, these components constitute the Pathlight VX
Controller. In High-Performance configurations, the Pathlight VX Controller also includes an FC switch.
Management Server
The Management Server (MS) is the server component of Pathlight VX. The MS manages the configuration
and status of the Pathlight VX components. The MS also regulates data flow to and from the storage disk
and controls the location where data is written on the disk. The MS provides policy-based data
management, with data placement based on access requirements, usage, and age.
The MS is also responsible to control one or more physical libraries attached to the Pathlight VX. The MS
periodically queries the physical libraries for status changes and available media.
The MS is a 2U enclosure that, together with the SNC (and in some configurations, the FC switch),
constitutes the Pathlight VX Controller. In the rack, the Pathlight VX Controller is covered by the ADIC bezel.
Figure 2
shows the front view of the MS, with the SCSI hard drives and power button identified. The MS
front panel is visible when the Pathlight VX bezel is removed.

1. Depending on the specific Pathlight VX configuration, the SNC houses either 1 or 2 FC blades. The Entry-Level
Configuration has 1 FC blade in the SNC. The Standard and High-Performance Configurations have 2 FC blades in the
SNC.
2. For instructions on removing the Pathlight VX bezel, refer to Starting Up the Pathlight VX
on page 17.
CAUTION
Figure 2 identifies the location of the MS power button. To start up or
shut down the MS, refer to Starting Up and Shutting Down the Pathlight
VX on page 17; do not simply press the power button. Failure to follow
this procedure can interfere with the Pathlight VX’s operation.
