This seminar
is a combination of our "Understanding IP Storage Protocols"
and "In-Depth iSCSI & SCSI Protocols" courses. This seminar provides a comprehensive understanding of the current development and deployment of IP Storage including IPFC, FCIP, iFCP, mFCP,
iSCSI and how standard TCP/IP networks are used in today's IP
based storage applications. This course starts out with an overview of storage networking concepts, provides a comprehensive examination of the TCP/IP protocols used in Storage Networks
with a particular focus on iSCSI and TCP/IP and also examines
the performance acceleration approach of TCP/IP Offload
Engines.
We will also provide a comprehensive examination of the current development of iSCSI and SCSI protocols. This explains the
puzzle of information available and puts it all together, from making connections, to how SCSI commands work, to deciphering mode & log pages, and sense data (SCSI error information). All the pieces of an iSCSI system are clearly explained, including what it takes to integrate iSCSI components into a working system. In class exercises and labs reinforce system concepts. We also look at the trend of the current iSCSI implementations and examine SCSI & iSCSI
protocol analyzer captures of real hardware configurations.
