If you are using SAS already you are probably better off continuing to use that. There almost nothing SAS cannot do, whatever data you throw at it. It sounds like you have big data and even if you do want to step away from SAS, you would probably want to lean towards Python, because it appeals to the high performance community and are more likely to get help there.
Ken Thomson, Denis Ritchie, et al....hats off to you all and this community!

MFI(4) BSD Kernel Interfaces Manual MFI(4) NAME
mfi -- LSI MegaRAID SAS driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device pci device mfi Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): mfi_load="YES" DESCRIPTION
This driver is for LSI's next generation PCI Express SAS RAID controllers. Access to RAID arrays (logical disks) from this driver is pro- vided via /dev/mfid? device nodes. A simple management interface is also provided on a per-controller basis via the /dev/mfi? device node. The mfi name is derived from the phrase "MegaRAID Firmware Interface", which is substantially different than the old "MegaRAID" interface and thus requires a new driver. Older SCSI and SATA MegaRAID cards are supported by amr(4) and will not work with this driver. Two sysctls are provided to tune the mfi driver's behavior when a request is made to remove a mounted volume. By default the driver will disallow any requests to remove a mounted volume. If the sysctl dev.mfi.%d.delete_busy_volumes is set to 1, then the driver will allow mounted volumes to be removed. HARDWARE
The mfi driver supports the following hardware: o LSI MegaRAID SAS 1078 o LSI MegaRAID SAS 8408E o LSI MegaRAID SAS 8480E o LSI MegaRAID SAS 9260 o Dell PERC5 o Dell PERC6 o IBM ServeRAID M5015 SAS/SATA o IBM ServeRAID-MR10i o Intel RAID Controller SROMBSAS18E FILES
/dev/mfid? array/logical disk interface /dev/mfi? management interface DIAGNOSTICS
mfid%d: Unable to delete busy device An attempt was made to remove a mounted volume. SEE ALSO
amr(4), pci(4), mfiutil(8) HISTORY
The mfi driver first appeared in FreeBSD 6.1. AUTHORS
The mfi driver and this manual page were written by Scott Long <scottl@FreeBSD.org>. BUGS
The driver does not support big-endian architectures at this time. BSD
