Technical Bulletin #496: SNSI File Interchange Service Update

Published on: 
January 15, 2015

Livermore Computing (LC) now offers two methods for moving files from the Open Computing Facility (OCF) to the iSNSI network. In addition to the existing method using tape technology and computer operator ‘sneakernet,’ a new method available now uses an electronic One Way Link (OWL).

From OCF to iSNSI

*this method is discouraged. Transfers only occur during normal working hours.

From iSNSI to OCF

Tape technology remains the only method available for users to transfer files from the iSNSI network to the OCF. To do this, users must first connect to tapefis on the iSNSI network. Data will be written to tape and transferred to the OCF by LC Operations staff. To retrieve transferred files on the OCF, users must connect to either snsitapefis (CZ) or rzsnsitapefis (RZ) depending on if the user is a CZ only or an RZ user.
