Hello, I am currently testing switching from Dell PERC hardware RAID cards to Linux software RAID and I wanted to see if anyone out there has anything this large or larger and can give me some tips. Basically I'm going to do a bunch of RAID1 mirrors (56 drives), RAID) those in sets of 14 and then stripe those 4 into one big array. We want to get the most spindles possible servicing disk requests and I wanted to know if anyone has tried such a setup. I have test hardware with 20 drives and it appears to behave nicely and I'm getting much better throughput from software RAID than the Dell PERC hardware RAID cards, but I wanted to make sure that this solution would scale up to 56. Looking at dmesg (MAX_MD_DEVS=256, MD_SB_DISKS=27) and looking at the /dev directory (up to 128 SCSI disks) it looks like it should, but I wanted to get some first hand experience, if there is any :) Thanks in advance.
