28 Planning to Install and Configure Pathlight VX

Installation, Configuration, and Integration Requirements

Pathlight VX installation involves two phases: hardware installation and configuration, and integration of the

Pathlight VX in the customer environment. This section provides information about Pathlight VX

configurations, and specifies requirements that must be met to successfully install, configure, and integrate

the Pathlight VX in the customer’s environment.

Table 20

provides details on the maximum number of virtual media, drives, and libraries that are supported

for each Pathlight VX configuration. Table 21

on page 30 through Table 27 on page 39 are used to gather

information to configure the FC Host(s) and FC ports, configuring virtual drives, virtual libraries, and media.

Table 29

on page 41 provides brief descriptions of the Pathlight VX Advanced Features (Archive, Early Tape

Creation, and Storage Policies).

Pathlight VX Virtual Capacity - Libraries, Drives, and Media

The maximum number of virtual tapes, drives, and libraries that can be created on a Pathlight VX depend

on the disk capacity of the system.

Pathlight VX supports up to 32 virtual libraries and either 20 or 40 virtual drives (depending on the number

of FC blades on the SNC). Pathlight VX supports only one virtual drive type per virtual library (you cannot

mix virtual drive types per virtual library). Pathlight VX supports both LTO-1, LTO-2, and LTO-3 virtual

media.

To determine the maximum virtual capacity of the customer’s Pathlight VX, locate the ordered configuration

in the first column (Pathlight VX Configuration) in Table 20

Note

If disk extension is enabled, ensure the number of virtual drives concurrently

mounted will not exceed available disk space.

CAUTION

Tape counts are calculated and may differ by ±1.
