Agenda: 

1) 05-019r1    SAS 1.1 OOB For SAS/SATA Support 
http://www.t10.org/ftp/t10/document.05/05-019r1.pdf 

Review draft white paper by Bill Bissonette concerning if damage to SATA
devices is an issue. The paper should include an explanation of when the
SAS signal levels would be delivered to the SATA device and give voltage
level and circuit examples to aid the analysis. Dan mentioned a concern
over long tem electro-migration. 

2) 04-378r0           SAS-1.1 Clarification of SATA Signaling Level
Specification [Olawsky] 
http://www.t10.org/ftp/t10/document.04/04-378r1.pdf 
  
3Gbps SATA numbers in tables: 
SATA and SAS specification specify amplitude differently, resulting in
significantly different minimum values. 
Pre-emphasis has not been included in simulations. 
How real is a worst case SATA device (rise time, amplitude, jitter)?
Experience is that SATA devices are much better than worst case. 
Eye closure concerns due to influence of reflections from ESD diodes,
connectors, etc. These factors may reduce the affects of pre-emphasis
and amplitude. 

3) Addition of FC PL-2 appendix 

Status of George Penokie's editing of the FC-PI-2 Annex B source
document received from Bill Ham. 

4) New 4X connector proposal needs to be drafted if it will be included
in SAS 1.1. (Molex?) 

5) New items
