I need to choise the storage type for a squid proxy server with 100Mb/s traffic.


Which is better for performance (don't care the data reliability) ?

This storage is only for the squid cache (not system disk).

I have 3 disk for the array.

I'm using centos 5

Have your read the entry in the Squid FAQ – Zoredache Aug 5 '11 at 21:26
Documentation's a fad. It'll never catch on. – womble Aug 5 '11 at 22:01

JBOD is the fastest. You can even get a better performance with SSD hard disks.

Not seriously: And if you don't relay on reliability then what about ramdisks? You can't beat their performance.

Thanks, do you know where I found a guide for JBOD configure ? I can't found anything. – Roberto Aug 5 '11 at 22:15
JBOD means "just a bunch". So just use them. Probably as Zoredache suggests or as MikeyB suggests. Nothing special. – mailq Aug 5 '11 at 22:23

ok, I understand. Thanks all. – Roberto Aug 5 '11 at 22:39
To configure squid with jbod. Install disks, setup one cache_dir per disk. – Zoredache Aug 5 '11 at 22:45

Your fastest option will probably be three separate mountpoints, one for each disk. Configure Squid to balance across them.
