Dell PowerEdge R730 SEDs

Hi,

I plan to acquire a R730 wih the following Har Drives

RAID 1

- (2) 300GB 15K RPM SAS 6Gbps 2.5in Hot-plug Hard Drive,3.5in HYB CARR

RAID 5

- (4) 600GB 15K RPM Self-Encrypting SAS 12Gbps 2.5in Hot-plug Hard Drive,3.5in HYB CARR,FIPS140-2,13G

Questions:

1. Will this be ok ? I just need the Data Disks (RAID 5) to be encrypted/

2. Can I have both 6 Gbps and 12 Gbps drives in the same unit?

3. Where can I get the vSphere 6 installer for R720 / R730 servers?

Thanks,

Paul
