Hi. I have 2 SunFire V490 servers running Solaris 10. We may have to upgrade with more memory on one of them to make it compatible with the other. Here's the one with 12GB of RAM:

Here's the server with 8GB of RAM:

Here are the capacity specs for a SunFire V490:
Code:
8 memory slots (DIMMs) per processor, 16 total slots per CPU/Memory Board
512MB, 1GB, or 2GB expansion (32GB maximum per CPU/Memory board, 64GB maximum when configured with 4 processors)
All memory DIMM slots must be fully populated.
On the server with 8GB RAM, are 16 slots for one CPU full of DIMMs, all 512MB in size? I'm not sure how to interpret the output. In other words, I'm assuming board A is full and board B empty.
Alternatively, on the 12GB RAM server, board A appears full with a mix of 512MB and 1GB DIMMs.
If my interpretation is correct, how can I upgrade the 8GB RAM server to 12GB of RAM? Must I throw away 8 * 512MB DIMMs and purchase 8 * 1GB DIMMs or can I populate 8 memory slots on board B with 512MB DIMMs? Not sure what's meant with "All memory DIMM slots must be fully populated" - is it referring to the 8 processor slots or the 16 CPU/memory board slots?
As you can see I use quadcore processor on my Solaris box

Empty means that RAM slot is unused
0 -> no error in memory
A0 -> probably means logic address of my RAM
Bank -> do not know about that

hi,
we have an e6900 and my sys admin says that the number of processors and memory were reduced to 4 and 8GB. However, a prtdiag |grep Memory returns 16GB of memory. So what is my system's memory? psrinfo returns 4 online and 4 offline CPUs.
Thanks.
