1 Overview of Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX This document is the primary reference and user’s guide for the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX based on the Intel® 6Gb/s SAS/SATA RAID On-a-Chip device. This document contains complete installation instructions for the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX and includes the product specifications.
Note: Convention of usage of important terms: Nytro Cache: This term refers to the SSD Flash module used for user data cache, called Nytro Cache. SSD: This term refers to external SSDs. Intel offers Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX family to provide enterprise proven performance acceleration and data protection for direct attach storage (DAS).
The Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX provides accelerated performance and improved manageability to MegaRAID with its two embedded Nytro Flash modules. The Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX uses Nytro Flash memory in front of the connected hard disk drive (HDD) volumes to create high-capacity and high-performance acceleration cache pools. The Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX is based on the LSISAS2208 RAID On-a-Chip (ROC).
— RAID spans 10, 50, and 60 • Internal drive bay support • JBOD mode support • Nytro Flash module helps protect cache in the event of power fail — no battery required • SuperCap kit (option) to protect DRAM content in the event of power failure • Faster rebuilds will occur due to servicing most storage requests from Nytro Flash module • Compatible with existing RWC2 management interfaces • Zero administrative overhead Configuration Scenarios You can use the Intel® RAID SSD Cache Controller RCS25ZB040/RC

2 Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX Hardware Installation Requirements The following items are required to install a Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX card: • An Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX card • A host server with an available x8 PCI Express* 3.0 slot Note: This card also works in PCI Express* first generation slots. The PCI Express* software is backward compatible with previous revisions of the PCI bus and the PCI-X bus.
Hardware and Software Installation Overview The following flowchart shows the steps necessary to configure your Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX and RAID system. Figure 3.
Quick Installation of the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX Use the following steps to install your Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX. These steps are for experienced computer users or installers. 1. Unpack the card and inspect it for damage. Unpack the card in a static-free environment, and follow good antistatic grounding procedures. Remove the card from the antistatic bag, and carefully inspect the device for damage.
Figure 4. Example of an Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX Board Installation and Cabling 7. Secure the card to the server’s chassis. Install the bracket screw, if applicable, or engage the server retention mechanism to secure the card to the server’s chassis. 8. Connect SAS or SATA devices to the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX. Make sure that the cable you use conforms to all specifications. 9. Perform a safety check.
— A CDROM drive containing Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX drivers for supported operating systems, RAID configuration utilities, an electronic version of this user’s guide, and links to other related documentation — A license agreement — Warranty information 2. Prepare the server. Turn off the power to the server, and disconnect the AC power cord. Remove the server cover. Refer to the server documentation for instructions.
Caution: The PCIe slot must meet the 300 linear feet per minute (LFPM) minimum airflow requirement but 500 LFPM is optimal for thermal performance. Figure 5. Example of an Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX Board Installation in a PCI Express* Slot 7. Install the SAS devices, SATA devices, or both in the host server case. Refer to the documentation for the devices for any pre-installation configuration requirements. 8. Connect the RAID card to the devices.
drivers. The Intel® RAID Software User’s Guide provides information on how to install and use the drivers. Be sure to use the latest service packs provided by the operating system manufacturer and to review the readme file that accompanies the driver. RAID Cache Protection Kit (optional) The RAID Maintenance Free Backup Unit 3 contains a RAID Cache Protection module and a mounding bracket.
SAS Device Cables and Connectors The figure below illustrates the cable necessary for connecting SAS or SATA drives to the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX card. Also the cable necessary to connect the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX card to an internal drive bay. Figure 7.
5. They permit the random deletion of logical drives that were created by using Intel® RAID Web Console 2 (refer to the Intel® RAID Software User’s Guide for more information). 6. They support the use of the remaining array capacity by Intel® RAID Web Console 2. The Intel® RAID Software User’s Guide provides detailed installation instructions for operating system drivers.

Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX Characteristics 3 All of the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX cards contain the same connectors and headers. Therefore, there is only one board illustration and description given in this chapter. Flash Memory Capacity The differences between the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX family of controllers are the amount of flash memory as shown in the following table: Table 2.
Dirty Cache LED Header (J1) J1 is an optional two-pin header for connecting an LED to indicate a write command is pending. This LED is known as the Write Pending LED. Use this LED with the write-back cache feature. The dirty cache signal is driven by GPIO(5) of the LSISAS2208. The table below shows how to connect an LED to the J1 header. Table 3.
Life Status LED The CR2 LED is mounted on the surface of the controller board. This LED is bicolor RED or GREEN and it indicates the life status of the Nytro Flash modules. See Figure 8 for the location of the CR2 LED. LEDs on the Backside of the board CRB1 Orange LED = fault LED CRB2 Blue LED = Status LED (whether off-loading or not) CRB3 Green LED = power Connectors This section describes the connectors and headers on the Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX card.
Modular RAID Key Header (J6) J6 is a two-pin header that provides for connecting a modular RAID Key board for upgrades. At this time, there are no upgrade options available. SAS/SATA Connector (J7) The Intel® RAID SSD Cache Controller RCS25ZB040/RCS25ZB040LX supports 6Gb/s SAS/SATA connections through connector J7. SATA or SAS device are connected directly to the card or through an expander. The cards contain one mini-SAS 4i connectors (SFF-8087) that contains four SAS ports.
