Abstract

As logical partitioning becomes popular the trend is to create a high number of partitions. This leads to a situation where there may not be enough I/O slots for each partition and some partition would be required to share the I/O using a hosting partition. Typically the hosting partition will switch packets at the link level between the external network and the other partitions. The performance of the whole degrades when one or more of the partitions joins multicast groups.
