I'm upgrading a mail system that currently runs on an old dell 2450 with u320 scsi drives.
I plan on clustering two webmail front ends and running the mysql and nfs mount on a seperate server. So I'm trying to foresee where the bottleneck would be in performance. Do i spring for 15k drives on the backened or will 10k's do fine. Keeping in mind that this is all going over a gigabit swtich, i'm wondering if the switch will be the real bottleneck. I'm not too worried about the horse power being an issue on the backened server.
I know it's tough to estimate with little to know statistics, but it's about a 1k user mail system. they run fine on this single dell as most of them use outlook anyway. Does anyone have feedback of running mysql/nfs over a gigabit switch? is it better to run a setup like openfiler/freenas and iscsi mount partitions? any feedback is welcome.
