For those storage professionals that require a deeper understanding of Ethernet technology; this seminar can be a standalone one day training module or it can be added to the iSCSI seminar as an add-on module.
This seminar covers the fundamental aspects of Ethernet (TCP/IP-based) technology. The seminar starts with “what Ethernet is” and “how it is applied” to all IP Storage options, a comparison of the different storage and network protocol stacks, and the standards used to define Ethernet technology. Next comes the basics of the technology including: frame format, MAC addressing, EtherTypes, FCS, topologies, CSMA/CD, and Jumbo frames. Ethernet switch learning, VLANs, making Ethernet “Lossless”, and protocols enhancements for the data center round out these fundamental topics. Finally the hardware characteristics including: transceivers, speeds, encoding, and module form factors complete link layer topics.
The seminar continues by covering IP essentials including: IPv4 & IPv6 dotted address notation, header details (length, Type of service – TOS, and a bunch of flags), and how datagrams are fragmented and reassembled. Next on the protocol stack are the TCP essentials including; well-known ports, TCP segment header components, TCP options, and connection management.
The seminar closes by summarizing all of today’s Ether-based protocols including; NAS, iSCSI, FCIP, and FCoE.
