SAN performance

[peterve]

Hi,

This question may be quite generic for this forum, but I guess the forum is filled with experts, so here it goes :

I'm building a project plan to implement a SAN in our environment. I'm struggling with some theoretical exercises such as determining the performance between clients and the disks in the SAN array. In fact, there are a couple of components that are not very clear to me
Suppose I want to use a iSCSI bases SAN, using Gigabit Ethernet. What would be the effective performance between the server that is hosting the SAN volumes and the SAN disks themselves ?
What are my options to make the SAN performing well compared to servers with built-in disks ?
Etherchannel/Bundling multiple ethernet connections? more controllers ? .... what else ?) Can you tell me what the impact of every extension would be ?

Where can I find an overview of all of the SAN components and their performance ?
(disks, disk array backplane, SAN controller, switches, iSCSI adapters, ethernet vs FC, ...)

thanks



thanks
