6 Cabling the ATL M2500 Library for Fibre Channel

SDLT/LTO Drive Cabling with a 1-GB SAN 0

For example, if you have SDLT or LTO drives and a 1 GB SAN,

Quantum recommends a ratio of one tape drive per FC420 SCSI port.

This means that three- and four-drive libraries would require a second

FC420 Fibre bridge, and five- and six-drive libraries would require

three FC420 bridges, as shown in Figure 3

FC420-Port Cabling

Note: SDLT and LTO tape drives are sometimes referred to as

Superdrives.
