SoftLayer's iSCSI storage allows customers to access disk space on a high-performance iSCSI target. The storage is presented as a block-level device that customers can format to best fit their needs. iSCSI storage resides on the private network and all bandwidth to the iSCSI target does not count toward your public bandwidth allotment.
iSCSI storage may be instantly added through “Add Other Service” under “Sales” in the Customer Portal.
