NUMA-Non uniform memory access


Most servers with multiple sockest like 32 sockets run on NUMA . Need to understand how this works

Apart from this HBA adapters cards

Blade server v/s clustor .. In clustor different machines are connected by heartbeat but in blade servers all the 4 cpu cells are housed up In one RAC one big machine like cupboard

Sockets are physical slots to hold processors. You cannot place dual core serves in multiple sockets. Processors like xeon are capable of multi socket
