VMware ESXi 4.1 installation issue
The BIOS reports that NUMA node 1 has no memory. This problem is either caused by a bad BIOS or a very unbalanced distribution of memory modules.
Any idea why I am getting this error. The server is installed with Win2k8 Standard edition at the moment and RAID is configured on it. It is an HP Proliant server DL380 G7 with 2 processors and 18GB of memory.
Its a brand new server.
Please help!

Excellent! Thanks, I found that it is not same size in the paired slots. I have asked my hardware vendor to come over and check this out. Will keep you all posted.

Thanks, This was the issue. Its sorted out now!
Some additional info:
System designers use non-uniform memory access (NUMA) to increase processor speed without increasing the load on the processor bus. The architecture is non-uniform because each processor is close to some parts of memory and farther from other parts of memory. The processor quickly gains access to the memory it is close to, while it can take longer to gain access to memory that is farther away.
In a NUMA system, CPUs are arranged in smaller systems called nodes. Each node has its own processors and memory, and is connected to the larger system through a cache-coherent interconnect bus.
The system attempts to improve performance by scheduling threads on processors that are in the same node as the memory being used. It attempts to satisfy memory-allocation requests from within the node, but will allocate memory from other nodes if necessary.
