2 Target Side Adapter Controller General Most computer systems are based on the PCI Express standard as a high speed backbone for interconnection of peripheral components with a host CPU. Typically all PCI Express based devices are located closely in a common enclosure. The PCI-SIG PCI Express External Cabling Specification addresses extended applications, such as split-systems or I/O expansion by means of a suitable copper cable, available e.g. for a x PCI Express link, up to m length. When used with an AOC (Active Optical Cable), distances of up to 00m can be bridged between host and target systems. The SXS-STRING is a target system adapter card for PCIe x external cabling. The board fits into the system slot of a CompactPCI Serial backplane. Two on-board quad-port G RAID controllers are used to distribute eight channels across a CompactPCI Serial backplane. Thus, up to eight based CompactPCI Serial peripheral slot cards in a target system can be controlled by a remote host system CPU, with a maximum PCI Express transfer rate of 0Gbps. The SXS-STRING serves as a high performance controller, suitable e.g. for configuring industrial storage systems. SXS-STRING EKF -- ekf.com

5 Theory of Operation SXS-STRING CompactPCI Serial PCIe External Cabling Target Side Adapter Controller The SXS-STRING allows to control a CompactPCI Serial target (downstream) system by a remote host CPU via PCI Express external cabling. The host (upstream) system may be any computer with a PCI Express external cabling adapter, not necessarily a CompactPCI Serial system. The SXS-STRING must be inserted into the system slot of the CompactPCI Serial target system. Being mainly a powerful controller, the SXS-STRING is organized similar to a CompactPCI Serial system slot controller card, however restricted to the resources of the CompactPCI Serial backplane. The SXS-STRING is connected to the host system by a PCI Express x front panel cabling connector. An on-board PCI Express packet switch establishes dedicated PCIe links for two attached controllers. Eight channels in total are available via the relevant backplane connectors P/P, sufficient for up to eight based CompactPCI Serial peripheral cards in a target system. Since the SXS-STRING is equipped with two quad port G controllers, the devices of the CompactPCI Serial target system are organized as x drives. Each controller can be individually configured for RAID level 0//0, or non-raid operation. EKF -- ekf.com

11 Target Side Adapter Controller Typical Application For distances up to 00m between host system and target system active optical cables (AOC) are recommended. Below m (e.g. when connecting racks in a common enclosure) a low cost copper cable is sufficient. Please note, that an AOC employs a host side connector and a target side connector, which must not be interchanged. A PCI Express copper cable however is configured identical at both endings. While a copper cable is spread spectrum clock (SSC) compatible, the AOC requires a constant frequency clock (CFC). For proper operation over AOC, setup the host interface (e.g. SX-SLIDE) for CFC.

15 Target Side Adapter Controller Power Sequencing Please understand, that host and connected target hardware should be considered as distributed parts of a common computer system. During BIOS POST the whole system will be explored for PCI Express devices attached to the PCIe root complex (processor on host system CPU card). Devices which are not active (powered up) at this time, will not be enumerated by the BIOS and are consequently not available for the operating system afterwards. Hence a power sequencing procedure must be observed for host system and target system. The rule is simple: Power up the target system before the host system, or simultaneously. If power sequencing conditions cannot be maintained, the host system must be restarted again, until the remote target devices are visible to the host CPU. If the host system is equipped with an EKF processor board such as the SC-LARGO or later, a startup time delay up to s can be configured via BIOS setup: Setup (F): Advanced -> Miscellaneous Configuration -> Execute Delay after Reset The adjusted delay would be executed before enumeration and initialization of PCI Express devices, thus permitting a reasonable power up time lag for the remote target system. The delay countdown is indicated by a red blinking LED GP in the CPU card front panel. EKF -- ekf.com
