Suggestions for VMware ESXi RAID arrays usage for best performance

Hi,

I am setting up a new WEB + MAIL + SQL server on brand new hardware.
As basis, ESXi is used with 2 Virtual Machines, running Windows 2008 Server 64-bit.

Now, server has 2 RAID arrays setup as follows:
RAID 10 array with 4 x 1TB SATA disks = approx. 2 TB of storage space
RAID 1 array with 2 x 300GB SAS 15k disks = approx. 300 GB of fast system space

Now, could you recommend me how to configure virtual machines/ESXi to gain the best performance out of these disks?
What to put where, how much space should I allocate for what etc.
I am kinda new into VMware.

thanx.

ADD-ON:
By "best performance" I mean, that I am looking for suggestions how to configure things to establish the fastest environment for WEB, MAIL and SQL servers inside ESXi.

Should I put virtual machines onto fast RAID 1 SAS array, and configure slower RAID 10 with SATA drives as D:\ drive for WEB and MAIL?
Or should I configure it somehow different?

Which means, I could use RAID 1 SAS array for SQL logging, and performance would be better, than in case of using SATA RAID 10 array for both, SQL DB and LOGS, right?
In best case scenarios, you want your OS, LOGS, and DATA to be on different spindles. If you only have those two logical disks to write to, then yes I would keep LOGS with my OS and DATA on the RAID 10.

If you have a test environment and can simulate production loads, it would be a good idea to keep an eye on the I/O for both drives. But as long as your DB is not too intense, I would probably set it up this way.
Thank you.
I'll wait for another week to see if any other better answers are given, and will reward and close question then.
