Muzete mi prosim tuhle problematiku vice priblizit? Nemam predstavu jak bych 
mohl MySQL pridelit
cely block device. Muzete me nakopnout spravnym smerem? Odkazy?
To same v pripade IO scheduleru.
Bude to, jak sjem jiz psal, dedikovany MySQL server. pobezi na nem par ne 
prilis vytezovanych
MyISAM databazi, ale prevaznou vetsinu zateze bude generovat databaze 
InnoDB.
Premyslel jsem o maximalnim vykonu, a premyslel jsem o dvou dedikovanych 
SCSI discich.
Jeden pro Data (MyISAM, InnodDB) + druhy disk pro BinLog + InnoDB log.
Tak to je tak moje situace. Muzete mi doporucit jiny zpusob?

Diky.
