DoubleStore

DoubleStore is a software layer unique to Technologic Systems that provides RAID-like filesystem redundancy on SD flash media. Using DoubleStore, robust file storage can be acheived either using 2 separate cards, or on one card by splitting its capacity in half. Furthermore, TS has put the ability to boot from a DoubleStore SD card in the low-level TS-BOOTROM startup firmware, thereby giving the benefit of a fault tolerant bootup of the Linux kernel and initrd on TS boards.

See our white paper on DoubleStore for more details.

If you are on a TS-75XX or TS-45XX see sdctl for more information on using doublestore in your product. For other products, see dblstorctl.
