To XFS to mono epipleon poy kanei, einai oti sou dinei th dynatothta *ws 
filesystem* na kaneis reserve ena kommati tou xwrou pou parexei gia 
real-time access. To XFS, gia o,ti apo8hkeyseis ekei, desmeyetai *oso 
pernaei apo to xeri tou* na prospa8hsei na roufhksei apo to layer poy 
brisketai apo katw tou ta dedomena kai na ta steilei sto layer poy 
brisketai apo panw tou, me ena sta8ero ry8mo. Tipote ligotero, tipote 
perissotero.

Apo kei kai pera, to na diasfalistei oti esy ontws 8a pareis ta dedomena 
me to ry8mo poy xreiazesai kai ta timing constraints poy exeis, den 
eksartatai mono apo to filesystem alla kai apo olo to ypoloipo systhma.

bandwidth guarantee tou XFS.

2) Isxyan thn epoxh pou to SGI Indy 8ewroutan to art of the state se 
graphics/video processing. Apo tote exei perasei POLYS kairos, kai exw 
thn ais8hsh oti shmera mporei na mhn exoun kai toso megalo nohma oso

Kontologis, to proteleytaio[1] pragma poy 8a se kanei na deis diafora 
sthn prosbash twn DV kai twn mp3 sou einai mallon to eidos tou linux 
filesystem pou xrhsimopoieis.
