King, III" Subject: Hello Sender: owner-linux-mm@kvack.org To: linux-mm@kvack.org List-ID: I'm not much of a kernel type, but I do have some formal background on OS working and reading through the Linux-MM site brought back lots of stuff. Anyway, I am working on a project where we have a large database split into 12 segments, and I want to put some of the indices in those segments into memory. The indices for all of the segments takes up about 4 GB. The database server is a multi-threaded proprietary one that I ported over to Linux - it already runs on MacOS (yes, true!), NT, Solaris, AIX. I have a couple of questions (assume I am talking about the latest versions of any component, like kernel or lilo or ramdisk): 1. If I purchase a Quad Xeon 550 with 4 GB of memory, will Linux work on it? (I saw the whole thing about tweaking kernel parameters to change from a 3:1 split to a 2:2 split) Should I just buy 2GB - will I be able to use the extra 2GB? 2. Can I create a large (let's say 1GB) ramdisk or memory filesystem? Obviously the more index I can fit into memory, the faster the result. I'd really, really like to use Linux here. It has proven itself as our mail/DNS server and hasn't crashed once in over 2 years, where we reboot NT servers weekly. I am willing to do some kernel hacking and experimentation. I have not been able to find another resource related to large amounts of memory with Linux. Hopefully through my experiences I will be able to produce a Linux VLM-HOWTO!
