Hi, we have recently ordered a Dell PowerEdge 6300 server with the following
configuration:
quad pII-450 Xeon processors
2 gb ram
3 x 9 gig lvd scsi hd's
perc2 raid controller
other useless stuff
Is there any issues with 2 gigs of ram and the quad processors? Dell
wouldn't ship the computer with 2 gb ram because it doesn't conform to
RedHat's guidelines or something, so I have to put it in once it gets here.
Can 2.2.x kernels handle 2gb of ram properly? What about the quad xeon
processors?
If anyone has a similar configuration, it would be gr8 to hear from you.
I have a Dell PowerEdge 6350 with 2G of RAM. To use the 2G you need to
recompile your kernel with the following changes: in files
/usr/src/linux/include/asm-i386/page.h and
/usr/src/linux/arch/i386/vmlinux.lds change 0xC0000000 to 0x80000000.
With this change you can address up to 2G minus epsilon (where epsilon is
about 50M) of physical memory but processes can have only 2G of address space.
(Without this change you could address up to 1G minus epsilon of physical
memory but processes could have 3G of address space.)
Note that with the above change, the stack sits at 0x80000000 instead of
0xC0000000 so you might need to reconfigure/recompile programs like the
Boehm-Weiser conservative garbage collector that need to know where the stack
sits.
Also note, that you will need to put
append="mem=1984M aic7xxx=no_probe"
in /etc/lilo.conf and rerun /sbin/lilo after you rebuild your kernel for
reasons too complex to describe here.
