We have a server that we are now ready to configure so as to serve our companies main databases to our staff situated across the country!
The question however!?
We would like to use RAID 10 for the database mount point in linux (RHEL 5). We have a nice Intel SRCU42X (PCI-Express) card serving 2 SCSI HDD backplanes (namely a 6 bay and 4 bay = ten disks) connected in the Intel SC5300BD2 server.
In your experiences, what is the best way to configure the ARRAYS and LOGICAL DRIVE in the Intel Raid Controller BIOS program? ie...I would like to have the RAID 10 volume configured in such a way so as to have the striping running between the 2 hard disk channels (the 2 HDD bays) and have the mirroring of each respective striped drive stay on that respective hard drive bay/channel?
Will this bring about max disk io performance??
Any suggestions would be much appreciated as we're ready to kick off with proceedings!!
A data block "abcd"
I II - Option 1 - STRIPES across the 2 scsi channels/hdd backplane
a a - Option 2 - MIRRORS running across the 2 scsi channels/hddbackplane
