building a RAID6 array with different disk sizes
Posted on 2014-04-24
I am building a virtual environment on a R710 server with PERC/6i controller. I am planning to go with a RAID6 array. I have four(4) 500 GB hard disks and two(2) 750 GB hard disks. Can I combine these and create 1 RAID6 array? The controller is showing me that I can get about 2.7 TB with this combination. Is it possible to build one array with different hard disk sizes and get the entire space or am I losing 250 GB on each of the 750 DB hard drives. Also the two(2) 750 GB disks on my Dell Poweredge R710 are displaying amber light after an initial green light (comes with green then changes to amber on and off). Is this because of this discrepancy? The drives are new and in good condition. The controller is not showing any errors on these two disks.
