Is this only an issue with multi-chassis cabled NUMA systems such as Altix 4000/UV and the (discontinued) IBM x86 NUMA systems (x440/445) with their relatively low direct node-node bandwidth, or is this also of concern with single chassis systems with relatively much higher node-node bandwidth, such as the AMD Opteron systems, specifically the newer G34, which have node-node bandwidth of 19.2GB/s bidirectional? -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
