Abstract

With the current implementation of the BladeCenter product, only one user is allowed to view the output of one of the fourteen blades at any point in time while the system is running. This somewhat limits the administrative power that could be available to multiple users. The following concept would give the capablility of allowing multiple users to access video streams from multiple blades simultaneously. By adding a DSP to each of the blades in the BladeCenter, we are able to pursue our goal of simultaneous video for each blade. This is different from the current design in that there is only one DSP in the BladeCenter (on the Management Module) and through the use of a KVM, it compresses the video stream from whichever blade is currently selected. By placing a separate DSP on each of the Blades, each DSP can locally process its own video stream, send it out onto the VLAN, and then send that VLAN stream out through the Management Module over ethernet. Another added benefit to adding the DSP to the blade would be the ablility to compress the Digital Video stream instead of the Analog Video stream that we are currently doing. This will add to the video quality of our remote video sessions. If cost becomes an issue, perhaps the ability to add the DSP tp the blade as an add-in module might work.

  Sending Digital Video from multiple Blades simultaneously through a DSP/VLAN Protocol

         In order to implement this idea, there needs to be a DSP on each Blade that will be in the BladeCenter. We would like to feed the DVO from the Video chip on the Blade into the DSP. By using the DVO stream, the DSP will be able to process higher quality video streams than the A/D converter that is on the Management Module. The DSP will compress the Digital Video and insert this compressed video onto the VLAN. This DSP algorithm is very similar to the one that is being used on the Raptor add-in card. The DSP on the Raptor card basically takes DVO stream from the video chip and compresses it to be sent out on the LAN. We are taking this idea to the next step by doing this on each blade and then allowing multiple users to access different systems at the same time. The VLAN packets then get sent over to the BladeCenter Switch Module and get passed to the Management Module. The Management Module then sends the compressed video stream from the VLAN out onto the ethernet to the requested user. Below is a block diagram illustrating this topology:
