Adding another raid controller to ML570.

We have an Proliant ML570 server with a 5300 RAID controller that is running windows 2000 and SQL 2000. Currently the server is configured with 1 mirror set for the OS and another mirror set for the log files, this is on Cage A of the server. Cage B is configure with 6 disk RAID 5 for the data files. We want to have the mirror that has the logs put on its own controller to get maximum performance benefits, if Cage A is connected to Channel1 and Cage B is connected to channel 2 of the 5300, how can I get this acomplish. I know i can just put another RAID controller in the server but where will the channel for this controller connect in Cage A that is where I have the mirror set for the log files? if the is another piece that I'm missing please advice. Thanks,

Hi,

It's not possible to split the Cage A or B there are only 2 Busses internal.

The only option you have is to buy an external drive enclosure and connect this to the extra Raid controller.
