iSCSI Disks

Internet SCSI

(iSCSI) is a standard that defines the encapsulation of SCSI packets in

Transmission Control Protocol (TCP) and their transmission via IP. On

SnapServers, an iSCSI disk is based on an expandable, RAID-protected volume, but

appears to a client machine as a local SCSI drive. This storage virtualization frees

the administrator from the physical limitations of direct-attached storage media and

allows capacity to be expanded easily as needed. Unlike standard SnapServer

volumes, SnapServer iSCSI disks can be formatted by the iSCSI client to

accommodate different application requirements.
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 initiator(s) to the SnapServer.

iSCSI Disk Limitations

• The iSCSI protocol limits the size of any iSCSI disk to 2TB.
• The GuardianOS can maintain up to 256 iSCSI disks.

For Additional Information

The following resources provide further information you may need to plan and

complete your iSCSI implementation.

SnapServer Online Help:

Available from the

Storage > iSCSI

screen, the online

help provides details on creating and managing iSCSI disks on SnapServers.
