Raid 10 on DL380 G5

I have got a HP Proliant DL380 G5 with a Smart Array P400 Controller. Is it possible to use RAID 10 with this controller? If so how many drives are required?

The SA-P400/256 supports RAID 0, 1, 1+0 and 5.

RAID 6 (Advanced Data Guarding) is available by adding either the BBWC upgrade or the 512 BBWC upgrade

Disk Requirements: An even number of hard disks with a minimum of four; All drives should be identical.

Array Capacity: (Size of Smallest Drive) * (Number of Drives ) / 2.

Storage Efficiency: If all drives are the same size, 50%.

Fault Tolerance: Very good for RAID 01; excellent for RAID 10.

Availability: Very good for RAID 01; excellent for RAID 10.

Degradation and Rebuilding: Relatively little for RAID 10; can be more substantial for RAID 01.

Random Read Performance: Very good to excellent.

Random Write Performance: Good to very good.

Sequential Read Performance: Very good to excellent.

Sequential Write Performance: Good to very good.

Cost: Relatively high due to large number of drives required and low storage efficiency (50%).

Special Considerations: Low storage efficiency limits potential array capacity.

Recommended Uses: Applications requiring both high performance and reliability and willing to sacrifice capacity to get them. This includes enterprise servers, moderate-sized database systems and the like at the high end, but also individuals using larger IDE/ATA hard disks on the low end. Often used in place of RAID 1 or RAID 5 by those requiring higher performance; may be used instead of RAID 1 for applications requiring more capacity.
