  7. 7. OneCore Storage SDK Highlights OneCore Storage SDK provides a common driver framework for: – All Emulex SLI-4 product platforms (XE201*, XE4310R, and future platforms) – All the Storage Protocols (FC, FCoE and iSCSI) OneCore Storage SDK replaces: – The Emulex iSCSI TDK – The Emulex FC TM SDK OneCore Storage SDK is on its 3rd Major Release – Over a dozen Storage OEM customers – Even more Development Portal customers OneCore Storage drivers can shorten development time in a number of ways: – Use “as-is” with a standard or custom Back-end interface – Leverage components of the driver as building blocks for your driver – Use as reference code along with the Emulex SLI-4 specifications to write your own driver * The XE201 is capable of Fibre Channel and Ethernet © 2013 Emulex Corporation 7

  13. 13. OneCore Storage SDKDriver Components Service Level Interface 4 (SLI-4) – The SLI-4 component implements the commands and processing defined by the SLI-4 Architecture Specification, SLI-4 FC and FCoE Command Reference, and the SLI-4 iSCSI Command Reference – The SLI-4 component provides a lightly-abstracted application programming interface (API) that enables access to the device hardware without enforcing a specific policy Hardware Abstraction Layer (HAL) – The HAL component provides an abstracted interface to the SLI-4 component to perform common operations, such as, port initialization, shutdown, and I/O - these operations can be performed without having to know the semantics of the SLI-4 interface – The HAL component also provides APIs for port and node management, command and event processing, as well as I/O handling Transport – The transport components provide protocol-specific and general transport handling – The FC/FCoE transport sub-component includes discovery, logins and BLS/ELS handling – The iSCSI transport sub-component includes connection establishment, connection offload and session management © 2013 Emulex Corporation 13
  14. 14. OneCore Storage SDKDriver Components (Continued) SCSI API – Part of the Transport layer – Provides a SCSI-like API for back-end initiator and target connectivity – Common across all three storage protocols (FC, FCoE, and iSCSI) – Includes APIs for sending/receiving SCSI commands and TMFs, sending/receiving data and SCSI status, as well as aborting I/O Operating System – Provides the OS services required by the OneCore Storage driver through an OS-independent API – Separate component are provided for Linux, FreeBSD, and User-Space drivers – Functionality includes: • Memory allocation, free, and cache coherency • Locking for concurrency protection • Linked list creation and handling • OS-specific PCI driver entry points and MSI-x/INTx interrupt handling © 2013 Emulex Corporation 14
  15. 15. OneCore Storage SDKDriver Common ObjectsThe OneCore Storage Driver Common objects provide a mechanism throughwhich the various OCS driver components share and track information. Thesedata structures are primarily used to track SLI component information, but canbe extended by other components, if needed. The main objects are: Domain – The ocs_domain_t object represents the SCSI domain, including any infrastructure devices such as FC switches and FC forwarders. The domain object contains both an FCFI and a VFI. SLI Port – The ocs_sport_t object represents the connection between the driver and the SCSI domain. The SLI Port object contains a VPI (virtual port indicator). Remote Node – The ocs_node_t represents a connection between the SLI Port and another device in the SCSI domain. The node object contains an RPI (remote port indicator) DMA – The ocs_dma_t object describes a memory region capable of performing direct memory access (DMA) transactions. © 2013 Emulex Corporation 15

  18. 18. OneCore Storage SDKLinux User-Space FC/FCoE Driver Overview The Linux User-Space FC/FCoE Driver is composed of three components: – Kernel Module – Common Linux FC/FCoE Front-End Components (same as kernel driver) – Emulex RAMD (same as kernel driver) Kernel Module (ocs_uspace.ko) – The User-Space driver includes a small kernel module (ocs_uspace.ko) that provides access to PCI resources, DMA buffer management, etc. – The Kernel module functionality includes: • Read/Write PCI configuration space registers • Read/Write per PCI function BAR memory regions • Mapping of per PCI function BAR memory regions to user space • Allocation and freeing of kernel resident DMA buffers and mapping buffers to user space. • DMA buffer synchronization (maintaining cache coherency) • Wait on interrupt © 2013 Emulex Corporation 18
