Does anyone have experiences about ARC-1883I SAS controller with CentOS7?
I am planning to have RAID1 setup and I am wondering if I should use the controller‘s RAID functionality which has 2GB cache or should I go with JBOD + Linux software RAID?
The disks I am going to use are 6TB Seagate Enterprise ST6000NM0034
7200rpm SAS/12Gbit 128 MB
If hardware RAID is preferred, the controller’s cache could be updated to 4GB and I wonder how much performance gain this would give me?
