To: t10@t10.org Subject: SSC-3: Tape end-to-end data protection (07-373r2; 07-374r2) From: Kevin D Butt <kdbutt@us.ibm.com> Date: Tue, 4 Sep 2007 17:13:36 -0700 X-Message-Number: 8031 Formatted message: HTML-formatted message I have updated my presentation and proposal on Tape end-to-end data protection. The presentation has been updated in an attempt to better show: 1) Why the disk end-to-end method is not a good candidate for tape solutions; and 2) Why the protection information length (i.e., CRC length) needs to be included in the transfer length and not just inferred. The proposal has been updated from the original incorporating feedback from four different companies. Many options have been removed. Clarifying text and figures have been added to the model clause. Text that is likely to get removed unless somebody fights to keep the related options has been highlighted.
