Introduction

The NI HDD-8266 series are applications of cabled PCI Express technology. These products leverage commercially available enterprise-class RAID controllers and hard drives.

About the NI HDD-8266 Series
Description and Features
The NI HDD-8266 is a 2U chassis specifically designed for streaming to and from disk applications by National Instruments. This chassis supports up to 24 enterprise-class SATA or SAS hard drives controlled by a 24-port PCI Express RAID controller. This system is preconfigured as RAID 0; however, the system also is validated to perform well under RAID5 and RAID6. The RAID card also supports additional modes such as RAID 1, RAID 10, RAID 50, and JBOD, but NI has not specifically validated these RAID modes for performance. Refer to the included RAID controller user manual or guide for more information about these modes.

NI HDD-8266 x8 System
The RAID system consists of an NI PXIe-8384 in a PXI Express or CompactPCI Express chassis, connected to the NI HDD-8266. This system can use the full bandwidth of PCI Express x8 (Generation 2) technology. In order to achieve maximum throughput, the PXI Express host controller and the PXI Express chassis must support x8 PXI Express devices. The NI HDD-8266 will work with non-x8 PXI Express controllers and chassis but at a reduced speed.

What You Need to Get Started
To set up and use your NI HDD-8266 for PXI Express, you need the following hardware and software to use with your PXI Express chassis and controller:

• Host: PXI Express controller and chassis
• RAID array: NI HDD-8266
•  Host connection: NI PXIe-8384
• Cable: PCI Express x8
• Software: RAID drivers (on the included CD)

Unpacking
Your NI HDD-8266 system is preassembled and preconfigured for use. You need only to remove the NI HDD-8266 RAID storage chassis from the shipping box and assemble your system. There is no need to open your NI HDD-8266 chassis. The system is preconfigured and sealed.

Caution Your NI HDD-8266 system is sensitive to electrostatic damage (ESD). ESD can damage several components on the system.
Caution Never touch the exposed pins of connectors. Doing so may damage the device.

To avoid such damage in handling the device, take the following precautions:

• Ground yourself using a grounding strap or by holding a grounded object.
• Touch any antistatic packaging to a metal part of the chassis before removing the device from the package.

Complete the following steps to install the NI PXIe-8384 in your PXI Express or CompactPCI Express chassis:

1. Power off your PXI Express or CompactPCI Express chassis, but leave it plugged in while installing the NI PXIe-8384. The power cord grounds the chassis and protects it from electrical damage while you install the module.

2. Locate an available PXI Express or CompactPCI Express slot in the chassis. Th I PXIe-8384 must not be installed in the controller slot (slot 1 in a PXI Express chassis).
   Caution To protect both yourself and the chassis from electrical hazards, leave the chassis off until you finish installing the NI PXIe-8384.

3. Remove or open any doors or covers blocking access to the slot where you intend to install the NI PXIe-8384.

4. Touch the metal part of the case to discharge any static electricity that might be on your clothes or body.

5. Make sure the injector/ejector handle is in its downward position. Be sure to remove all connector packaging and protective caps from retaining screws on the module. Align the NI PXIe-8384 with the card guides on the top and bottom of the system controller slot. Caution Do not raise the injector/ejector handle as you insert the NI PXIe-8384. It will not insert properly unless the handle is in its downward position so that it does not interfere with the injector/ejector rail on the chassis.

6. Hold the handle as you slowly slide the module into the chassis until the handle catches on the injector/ejector rail.

7. Raise the injector/ejector handle until the module firmly seats into the backplane receptacle connectors. The front panel of the NI PXIe-8384 should be even with the front panel of the chassis.

8. Tighten the bracket-retaining screws on the top and bottom of the front panel to secure the NI PXIe-8384 to the chassis.

9. Replace or close any doors or covers to the chassis.

Cabling
Connect the cabled PCI Express x8 cable to both NI PXIe-8384 and the NI HDD-8266 chassis. The cables have no polarity, so you can connect either end to either the card or chassis.

Caution Do not remove the cable after the system is powered on. Doing so can hang or cause errors in applications communicating with devices. If a cable becomes unplugged, plug it back into the system. (You may need to restart your computer.)

Hardware Overview

This section presents an overview of NI HDD-8266 hardware functionality and explains the operation of each functional unit.

Functional Overview
The NI HDD-8266 is based on PCI Express technology. The NI PXIe-8384 paired with the NI HDD-8266 uses PCI Express drivers to enable control of a PCI Express RAID card in an external chassis. The PCI Express Redriver architecture is transparent to device drivers, so only the RAID driver is needed for the NI HDD-8266 to function. The link between the PC and the chassis is an x8 PCI Express link (Generation 2). This link is a dual-simplex communication channel comprised of low-voltage, differentially driven signal pairs. The link can transmit at a rate of 4 Gbps in each direction simultaneously in x8 mode.

LED Indicators
The LEDs on NI HDD-8266 cards give status information about power supplies and link state. The back of the NI HDD-8266 has two LEDs, one for power supply status and one for link state.
Table 1 describes the meaning of the LEDs on the back of the NI HDD-8266.
