Memory Error Log Summary

The memory error log is empty.

Question:
1) How many memory still can be added for above 2 servers? And what is the max MB per single memory that these 2 servers can support?

2) For RP5470, there is some errors on the memory. How I'm going to troubleshoot based on these errors messages?

3) How many CPU still can be added for above 2 servers? What is the max mhz per single CPU that these 2 servers can support?
For RP5470 & RP7410, both current CPU is 2 x 875 MHz, PA-RISC2.0, v.

regards.

[Pete Randall · Accepted solution]

1) RP5470 - up to 16 GB memory, RP7410 - up to 64 GB memory

2) single bit errors should not cause any problems

3) RP5470 - up to 4 PA8700, 875 MHz CPUs, RP7410 - up to 8 PA8700, 875 MHz CPUs

Hi,

Thanks for your fast response.

Q1) For RP5470, there are total 16 slots. The max memory that can support is 16GB. Is means that 1 slot can support up to max 1GB?

Q2) For RP7410, there are total 16 slots. The max memory that can support is 64GB. Is means that 1 slot can support up to max 4GB?

Q3) How to find out the available memory & CPU slots? What I mean is in order to add the memory & CPU up to max for these 2 servers, do I need to buy extra slot/scsi? Or the server itself already come with all the slot/scsi?

regards.

[Pete Randall]

q1) yes

q2) yes

q3) the slots are already there, you just need to fill them

[Pete Randall]

Maybe I should re-consider that response, at least q1 and q2, anyway. I seem to recall that the older N-class had memory carriers and you had to purchase a second carrier to fully expand. I'm not sure if that is the case with the newer rp series, but will see if I can find out.


Pete

[Pete Randall]

The rp5470 does seem to have a memory carrier available which provides 8 additional slots, but you already have 16 slots, so I suspect you have two carriers already.

I'm still searching for an answer on the rp7410.

hi, rp7410 can have 64gb max memory if 2 cell baords are installed.


It is 32gb 16 slots and 4 processors per cell board.

part numbers of mem upgrades are here

Hi,

RP7410
max 16 GB per cell board,32 GB with two cell boards

The minimum cell configuration includes two active CPUs and 1 GB of memory per cell board.
The maximum configuration includes four active CPUs and 16 GB of memory per cell board.
Memory DIMM modules for the rp7410 are sold in sets of four (quads), with DIMM board
sizes of 256 MB, 512 MB, and 1 GB available at first release. Memory quads of different
sizes can be mixed within a chassis and within a cell. However, for optimum memory
interleaving and performance, it is recommended that one memory size be selected and
distributed evenly across available cells.

Andrew is correct, support for 64 GB mem has been added in 2003

Hi,

1) For RP5470, the default memory slots is 8 with each max up to 1GB and can support up to 2 CPUs. But according to the nickel info, currently the server seems like has 16 memory slots and can support up to 4 CPUs without buying any extra cell board/slots. Am I right?

2) For RP7410, 1 cell board consists of 16 memory slots with each max up to 2GB and can support up to 4 CPUs. Based on above kernel, currently the server seems like has 1 cell board. Am I right?

regards.
