Hello,
I am not exactly sure if this question is under the right heading but, here it goes.
I am in the process of converting from a hardware RAID to a software RAID system (woot!) for my home NAS using openmediavault. In planning the system I was thinking of going for the G3240 model pentium as it has frequency scaling and a rather nice price but, I realized that I had never done software RAID and had always used adaptec cards in the past and was not knowledgeable enough to make the right choice here, so got a few questions.
Short info before the questions:
- NAS is used for backup and as a file-server
- Has 4 x 3TB WD REDs (I love RAID 10, would like to keep it that way)
- Has mSATA 24GB sandisk ssd (Debian and openmediavault)
- Has 8GB DDR3 SODIMMs non-ECC
- ext4 file system
- Supermicro X10SLV-Q mobo in hand (mobo can change, depending on answers to my questions)
Questions:
- Does the number of cores and/or hyper-threading have an effect on software RAID and is it worth going for quad or octa cores?
- Does the mobo chipset have an effect on software RAID performance (for ex. q87 vs C224)?
- Which software RAID should I choose for my NAS (transparent RAID, etc.)?
- Is it better to use adaptec 3405 JBOD (have in hand), a seperate HBA or attach drives directly to mobo for software RAID, does it matter?
Thanks people.
