Module 7: IP SAN, FCoE, NVMe-OF (Overview of IP SAN)

Question 1

What is an IP SAN?

Answer 1

uses Internet Protocol (IP) to transport block IO over LAN

Question 2

Why would users want to use an IP SAN?

Answer 2

more cost effective than FC SAN
want to use existing IP network for ease of management

Question 3

Why do most organizations build a smaller separate LAN for their IP SAN?

Answer 3

LAN must handle continuous peak demands of storage traffic load without impacting normal user data traffic - sometimes existing LAN can’t handle this workload

Question 4

What is iSCSI?

Answer 4

IP based protocol that enables transporting SCSI data over IP network - inexpensive and easy

Question 5

How does the iSCSI protocol work?

Answer 5

encapsulates SCSI IO into packets and transports them using TCP/IP

Question 6

What is FCIP?

Answer 6

IP based protocol used to interconnect distributed FC SAN islands over an IP network

Question 7

How does FCIP work?

Answer 7

encapsulates FC frames onto OP packets and transports over existing IP network - enables transmissions by tunneling data between FC SANs

Question 8

What is FCIP used for?

Answer 8

transporting FC protocols and SCSI block IO over long distances - best way to interconnect geographically dispersed FC SANs over WAN
