In addition to the space required for standalone libraries, a CLM library requires 52 inches (130 cm)
of clear space t
o the left of the primary cabinet as you face the front of the cabinets. See the section
called Floor space in HP StorageWorks ESL E-Series Tape Library unpacking and installation guide
for fur ther information.

that has already been expanded to full capacity using purchased licenses installed using Command
View TL. Secondar y cabinets must b e ESL 712e or 630e libraries.
The primary cabinet must have between 1 and 5 fully-populated clusters (that is, each of these clusters
must contain 4 drives). Cabinet 2 in the library must have at least 1 drive cluster containing at least 1
drive, and may have up to 6 fully-populated clusters. Other secondary cabinets must have at least 1 drive
cluster containing at least 1 drive, and may have up to 2 fully-populated drive clusters. The entire library
can have up to 11 clusters and up to 44 drives. Maximum slot count in a 5 cabinet library is 3,560.
Cross Linked systems contain the following additional parts:
• Cross Link arm (CLM arm)
• Cross Link robotics controller (CLM robotics controller)
The CLM arm (see Figure 14) is used to send a shuttle between libraries. The shuttle carries a data tape
cartridge so that it can be stored in a secondary cabinet or retrieved for use, as necessary.

The CLM robotics controller (see Figure 15) is located on the primary library only, just above the cabinet
controller. In an individual library, this would be considered the number 5 drive bay. The controller
contains the power supplies, CLM electronics PWA, and Ethernet hub for the CLM robotics. It supplies
power to and controls the CLM.
