  ARR2 caching and sizing Reply Contact We are woking on a smooth streaming design, and we what to use ARR2 for load balancing and caching.   Is there any memory / CPU recommendations on a ARR2 server with 10Gbit NIC.   We plan to make 2 RAID0 cache volumes on each ARR node. if a cache volume fail, the ARR node will ask the origin server for the missing data, and there will not be any interruptions on the streams. Or am i wrong here ?   Is there any documentation available on DVR on live smooth streaming. Is it using the ARR cache for DVR.   Regards Søren Ravn

  Re: ARR2 caching and sizing Reply Contact It's difficult to make a blanket recommendation on CPU/memory without knowing the traffic pattern of your usage.  As you may have guessed, the first bottleneck that you are going to hit is disk i/o.  Depending on the average size of the files that are being cached, you may or may not be able to saturate the NIC. That said, we do have some deployment recommendations that are applicable to ARRv2 deployment in general.  It can be found at Deployment recommendations for Application Request Routing.  As for your last question on DVR on live smooth streaming (LSS), it depends on what you mean by that.  In an upcoming release of LSS, there is a role that gets enabled when ARR is installed.
