Configuring Iscsi Initiators - Overland Storage SnapServer Administrator's Manual

SnapServer/GuardianOS 7.5 Administrator's Guide
Connectivity to the iSCSI disk is established using a software package or PCI card, known as
an initiator, that must be installed on a client machine. The initiator sees the SnapServer as a
"target portal" and an iSCSI disk as a "target."
To use the SnapServer as an iSCSI target, you need to configure iSCSI on both the client
initiating the iSCSI connection, and on the SnapServer. Use the information presented here in
conjunction with the documentation supplied with your initiator to install, configure, and
connect the iSCSI initiators to the SnapServer.
iSCSI Disk Limitations:
• The the size of any iSCSI disk is limited to the size of a single chassis filesystem.
• GuardianOS can maintain up to 256 iSCSI disks.
