Hail folks. I've to set up an ~1TB SAN on our network. We're thinking about recycling an existing server with an HP SmartArray 641 RAID Controller and expanding it with another SA641 controller and some more disks, or directly purchasing an HP fiber Storage Area Network. In both cases I'll have to create a unique logical volume, and I'm wondering which logical volume manager to use. The machine will be a production system, it must be stable and reliable, fairly fast in disks access, and I'd like to run a 2.6 kernel on it. Lately I've used EVMS on some small systems and it left me well impressed; is it sufficiently mature and stable to be used with good results on such a system? Are there other _valid_ alternatives? And, of course, I'll have to use a journaled filesystem on top of the LVM. The average size of the files is about hundreds KiloBytes, seldom reaching the whole MB. The directories hierarchy will be fixed and highly structured, organized like this: /Year/ |__Month/ |__Day/ |__Hour/ |__Minute/ The number of stored files will be about 1,5 millions, and the estimated access rate will remain lower than 1,000 access/sec, with 30% write and 70% read. I've played for so long with ext3 and XFS filesystems, but both seems to have efficiency problems with setups like this. May someone give me some advices about the filesystem choice? Could ReiserFS be a valid solution? Should I consider other filesystems? Thanks to all.
