We do this via construction of a RAID 10 volume of 10 EBS 64M volumes.
This will take some time so let's get it going immediately.
Strapping together an mdadm volume for RAID
root ~]# yum install mdadm

[root@ ~]#
now we being creating a raid10 array with 10 devices with 256k chunks
mdadm --create /dev/md0 --level=10 --raid-devices=10 /dev/sd[fghijklmno]
make sure the create has begun by checking mdstat
[root@~]# cat /proc/mdstat
Personalities : [raid10]
md0 : active raid10 sdo[9] sdn[8] sdm[7] sdl[6] sdk[5] sdj[4] sdi[3] sdh[2] sdg[1] sdf[0]
314571520 blocks 256K chunks 2 near-copies [10/10] [UUUUUUUUUU]
[>....................] resync = 2.2% (7133112/314571520) finish=95.2min speed=53807K/sec
.... Call back in 95.2 minutes when your raid build should be complete.
