Recently I am trying to consider deploying SSDs on search machines Each machine runs data-nodes + shard-server and local reads of hadoop are leveraged….
SSDs are a great-fit for general lucene/solr kind of setups. But for blur, I need some help… 1. Is it a good idea to consider SSDs, especially when block-cache is present? 2. Are there any grids running blur on SSDs and how they compare to normal HDDs? 3. Can we disable block-cache on SSDs, especially when local-reads are enabled? 4. Using SSDs, blur/lucene will surely be CPU bound. But I don't know what over-heads hadoop local-reads brings to the table… Any help is much appreciated because I cannot find any info from web on this topic -- Ravi
