Just a few hints I give to my co-workers:
- take care when buying rack-mount case: you may have trouble adding
extension cards when choosing smaller than 3U ; and it's quite difficult
to find in Hanoi too: our usual provider had to buy it from HCMC ;
- buy plenty of RAM (from 1 to 64 GB), so that most frequent disk access
will be cached in RAM (Linux make use of all unclaimed RAM for
buffer/cache) ;
- if you need quick random access to data then you should probably use
SCSI disk since the SCSI card will organize data access in the most
efficient manner (reorder them to reduce mecanical movements) ; ATA
(IDE/PATA or SATA) on the other hand will require more CPU time (not
power, but "busy" time waiting for I/O) since the CPU will have to do
everything by itself ;
- by the way, if you need CPU processing, choose one with large L2 cache
(>= 1 Mo), not some loose one like a Celeron ;
- and last but not least, storing data is one thing, but don't forget
about saving it! RAID-1 will only preserve from data loss because of one
disk failure, but not full data loss in case of two disk failing at the
same time, or fire in the computer or just some bad guy/program
intruding the server and removing/corrupting everything... Here I
recommend the "backuppc" wonderful free software.
