Connectivity
The Scalar 10K offers several different connectivity options,
allowing the library to support a wide range of backup
topologies and applications. Flexible library connectivity
delivers active support for loop and switched fabric Fibre
Channel protocols, along with SCSI.
SAN Connectivity
The Scalar 10K can be connected to a Fibre Channel Storage
Area Network (SAN) via the Storage Network Controller
(SNC). See Figure 2-8 on page 2-17.
The SNC provides four SCSI bus connections, one ethernet,
and two Fibre Channel connections. The SNC allows native
SCSI devices (for example: library controller and tape drives)
to be seen by any hosts that are attached to the SAN.
The library controller and the tape drives access the SAN via
the SNCs, which can be installed in a Scalar 10K CM or a DM.
LTO drives can also attach to the SAN through the Native
Fibre Channel interface available.
For Dual Aisle configurations, the Scalar DLC controls the
cartridge accessors and the SNC controls the tape drives.
