Dears, We've installed a cluster of one collection of 350M documents on 3 r3.2xlarge (60GB RAM) Amazon servers. The size of index on each shard is about 1.1TB and maximum storage on Amazon is 1 TB so we add 2 SSD EBS General purpose (1x1TB + 1x500GB) on each instance. Then we create logical volume using LVM of 1.5TB to fit our index.
The response time is about 1 and 3 seconds for simple queries (1 token). Is the LVM become a bottleneck for our index? Thanks for help.
