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.

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.

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 data _at_ 100, 200, 400 Mbps
  (Cable).
• Transferring data _at_ 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.

iSCSI initiator Specification

• Hardware Initiator is a PCI-X or PCI-E card
• 1.Adaptec ASA 7211
  2. QLogic SANblade 4010/4040
  3. Intel PRO/1000 T IP Storage Adapter
  4. Emulex GN9000/SI
• Software Initiator
• 1. Piece of software.
• 2. CPU is responsible for
  decoding/encoding the data.

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

Conclusion

• The main barrier are ----
• High speed internet connectivity.
• Power requirement for Camcorder to transfer
  the data.
• Digital video coding standards.
• IEEE 1394 Interface OS support
• cost of the iSCSI hardware system.
