I'm building a SAN device to replace the NAS connected off my existing server.
Speed was an issue with ~20-30 clients so switching from 1Gbt to 4Gbt seemed like the best solution.

What would be the best type of way to setup 10x WD NAS red 4TB disks and what is the best raid hba card for this type of setup?

The current setup is a a 4Gbit Fibre channel link to a windows server with 2 locally attached hard disks which according to my understanding are in SCSI block format like JBOD?
being new to enterprise equipment and jargon I'm quite out of my depth with SAN setups.

I was considering using this LSI Logic LSI00208 MegaRAID SAS 9260-16i I'm unsure if this is overkill or not.

I was also wondering the best way to join the disks together whether hardware raid is the best option over client side software raid over the 4Gbt fibre.

I currently have 10 unused 4TB WD NAS and I was wondering the best way to set them up in a SAN.

The LSI MegaRAID SAS setup will give you great throughput - I would suggest getting the SAS drives to put in the array - usually I go with 160GB or 320GB (depending upon the size of the array). The larger hard drives will slow performance on the LSI controller.

It is always best to have the OS drive in a Non-RAID setup - run them as 2 separate drives (depending upon the size - one for the OS and a few programs - the 2nd for applications and temporary space).

Avoid software RAID in a server - you want the hardware RAID to give you performance and reliability.

If NAS was a good solution previously, why not just get a better performing NAS. Get one that supports 10GE and a switch with 10GE support. I know SOHO Qnap has NAS that support 10GE. NAS is generally simpler to admin than SAN. Something like a Synology DS3612sx or DS3614sx would be a good choice. I see prices around $3K for the DS3612sx -- The DS3614sx is rack mountable and has dual power supplies.
