Hi, I'm putting together a cheap indexing server for an "explorative" lucene project and had a few questions about which route to go.
I am going with a Socket 939 platform - does it make sense to get the dual core Athlon 64 X2, or is it better to stick with a faster clocked "plain" Athlon 64? Also, would Lucene benefit from running in 64 bit mode, or does it prefer "compatibility" 32 bit? I figure most indexing apps will be heavily IO bound, so I am stressing that, while staying with commodity components, so: WD SATA disks (250GB, 16MB cache, SATAII 3Gb/s) starting out with 4 of these (plus system disks), on the onboard controller (RAID0) If need be I can add two disk cages, 5 disks each with two decent SATA RAID controllers (64/128MB cache, NCQ, that sort of thing); the nForce4 PCI-Express should stand up to this, I'm hoping. And of course I am limited to 4GB RAM. I have three main applications in mind: Indexing PubMed/Medline article abstracts, this would we an index of about 15 million records with a couple of identifier fields, a title and a 1-3 paragraph abstract. Mostly the searches will be keyword searches on the text fields. Potentially I could add full-length papers to this as well (a lot fewer records though). Second one is indexing a couple hundred thousand MS Office documents and PDF files (Google Appliance sort of thing). And finally a genetic database repository a la LuceGene, or SRS. This would have more complex records (ie many fields, but little data with each), which are mostly retrieved on unique identifiers (very little text searching). This would probably run to a few tens of millions of records, maybe around 100 million eventually. Given these applications, what else should I be thinking about, hardware-wise?
