I was buying to Dell MD-1000 storage boxes each with 15 SAS 15k RPM disks
each of 240 GB. A muscular server connects to each one via SAS cables and
dedicated hardware RAID controllers. I was planning on running two RAID5
arrays of 7 disks each on each box (i.e. total of 4 arrays)
The problem is that the controllers export each array as a seperate device
/dev/sda1 etc.
I can always aggregate via. LVM but our tests show a 3x performance hit
when the LVM is intrduced.
Has anyone been in similar situations? What are way's out of this? I have a
bunch of users I'll be using the boxes to host.
Now I could split them as /home1 /home2 etc. and mount each on a seperate
decie. Downside is that there is no load balancing. What if all access is
on /home1 then I have a hot spot.
Any sugesstions?
