Rapid storage devices development for storage and telecom OEMs

Customer case study: Breakthrough Systems
Breakthrough’s innovative software solutions enable storage and telecom OEMs to quickly and cost-effectively bring to market diverse storage devices and systems, ranging from tape and disk drives to advanced arrays and libraries, by accelerating target mode driver development. VARs and OEMs typically bundle BSI’s various virtualization offerings with a hardware device to offer a turnkey storage virtualization appliance.

The SCSI Target Mode Driver component is a platform agnostic module used on embedded applications running Linux and other operating systems. It provides infrastructure for the access to the storage interface hardware (Host Bus Adapter) within a general-purpose operating system. The BSI SCSI Target Mode Driver implements the functionality of what is known as the SCSI transport services layer. The SCSI transport layer can be a traditional parallel SCSI, SAS, Fiber Channel or iSCSI. Commands, status and data are sent and received via the Target Mode Driver API.

BSI’s user level applications as the Virtual Disk Software (VDS) and Virtual Tape Library (VTL) use the Target Mode Driver to access the hardware on the supported operating systems.

“WinDriver was selected to provide platform portability for our storage interface hardware driver components for the most popular GPOS” says Terry Spear, BSI’s CTO. “The BSI software is designed to be platform independent supporting both embedded real time (RTOS) and general purpose operating systems (GPOS). WinDriver was the enabling technology to allow our software to be platform independent in the latest generation GPOSs. It also allowed our embedded storage interface driver products to be quickly ported to Linux and Solaris.” 


“Our alternative to using WinDriver was to build a traditional OS specific driver for each storage interface HBA we wanted to support. This created a “m x n” problem of the number of unique drivers we would have to create and support. As a cost savings move, BSI used WinDriver to reduce the “m x n” to “n”.”

Breakthrough Systems SCSI Target Mode Drivers control PCI Host Bus Adapter products. The drivers access ASIC registers, set up PCI Bus master DMA and respond to interrupts.  The WinDriver APIs are used for DMA mapping, interrupt control and general high-performance PCI access. WinDriver’s unique architecture also allows this layer to be implemented in the user mode.

About WinDriver Jungo's WinDriver automates and simplifies the development of user mode device drivers and applications for USB / PCI / PCI Express / CardBus / ISA / PCMCIA / PCI-X / and CompactPCI under Windows 98/Me/NT/2000/XP/XP Embedded/ Server 2003, Windows CE, Linux, Solaris and VxWorks. WinDriver provides a complete solution for creating high performance drivers and custom hardware access applications, thereby enabling device manufacturers to focus on their driver's added-value functionality, instead of on operating system internals and the DDK. Enhanced Built-in support is available for Actel, Altera, Atmel, Cypress, National Semiconductor, PLDA, PLX, Microchip, Netchip, QuickLogic, Silicon Laboratories, STMicroelectronics, Texas Instruments and Xilinx.
