2. Outline Introduction. How iSCSI works. How cam coder works?
Requirement For Implementation.
System Setup.
IEEE 1394 Interface
iSCSI Initiator and Target
Conclusion.

3. Introduction
To provide the iSCSI storage solution for the camcorder application.
Camcorder are the devices which are used for making videos and provides digital information.
Application of iSCSI to the camcorder can be applied by storing the video collected at a remote distance by using the existing TCP/IP protocol.
It can be a smart storage solution for overcoming the cost of the memory used in storing the data.

5. How iSCSI Works? 1 User issues a request for data to a local server2
The SCSI command is
encapsulated in TCP/IP & transmitted
over IP Network

The packet is decapsulated
separating the SCSI commands 5
The data request is again encapsulated in TCP/IP
then returned 4
The SCSI commands are received by the
Internal SCSI Controller, and the data
is retrieved.

6. iSCSI Benefits Leverages existing investment in technology and skills.
Relatively low implementation costs.
Similar speeds to fibre channel.
10 Gig Ethernet, 40 Gig announced.
No distance limitations.

7. Requirement For Implementation
High speed Internet(20Mbps ~30Mbps).
Video Coding Standards (MPEG,TIFF etc).
iSCSI hardware Initiator.
The internet connection should have to be Reliable.
The power required for Camcorder to transfer the Digital Data on high speed connection.
The IEEE 1394 standards for transferring the data from camcorder to the iSCSI initiator.

8. Speed Requirement

9. Off-load Engines

10. Camcorder Operation

14. System Setup Hardware iSCSI initiator IEEE 1394 Interface
Adaptor
TCP/IP
Network
iSCSI Target
PDA
iSCSI server

15. IEEE P1394(FireWire) Interface
IEEE 1394 is a low cost audio/video digital interface.
A digital interface
There is no need to convert digital data into analog and tolerate a loss of data integrity.
Transferring 100, 200, 400 Mbps (Cable).
Transferring 12.5, 25 or 50 Mbps (Backplane)
Physically small.
There is no need for terminators, device IDs, or elaborate setup
Isochronous Transfers
The 1394 protocol is a peer-to-peer network with a point-to-point signaling environment.
SRP (US) $60.00
3-port FireWire® Card Bus IEEE 1394

16. Digital Data Transmission

17. iSCSI initiator Specification
Hardware Initiator is a PCI-X or PCI-E card
1.Adaptec ASA QLogic SANblade 4010/ Intel PRO/1000 T IP Storage Adapter Emulex GN9000/SI
Software Initiator
1. Piece of software.
2. CPU is responsible for decoding/encoding the data.
Hardware initiator

18. iSCSI Target Specification
Server chassis with multiple hard drive bays (usually hot swappable)
Motherboard, CPU and memory
Multiple hard drives
One of more RAID controllers
One or more network interfaces
Target software package
iSCSI Target Server

19. Conclusion The main barrier are ----
High speed internet connectivity.
Power requirement for Camcorder to transfer the data.
Digital video coding standards.
IEEE Interface OS support
cost of the iSCSI hardware system.
