Introduction

The LSI MegaRAID SAS 9280-8e RAID controller addresses data throughput and scalability requirements across midrange and enterprise-class server platforms. This controller provides: – 6.0 Gb/s Serial Attached SCSI performance – 3.0 Gb/s SATA II performance – Eight-lane, 5-Gb/s PCI Express host interface The SAS 9280 RAID controller uses the LSI intelligent Battery Backup Unit 07 to provide cached data protection and allows system builders to protect cached data even during the most catastrophic system failures. The SAS controller supports the ANSI Serial Attached SCSI standard, version 2.0. In addition, the controller supports the SATA II protocol defined by the Serial ATA specification, version 1.0a. Supporting both, the SAS interface and the SATA II interface, the SAS controller is a versatile controller that provides the backbone of server environments. Each port on the SAS RAID controller supports SAS devices, SATA II devices, or both.

V CAUTION!

6



The actions described in this manual shall be performed by technical specialists. A technical specialist is a person who is trained to install the server including hardware and software.



Repairs to the device that do not relate to CSS failures shall be performed by service personnel. Please note that unauthorized interference with the system will void the warranty and exempt the manufacturer from all liability.



Any failure to observe the guidelines in this manual, and any improper repairs could expose the user to risks (electric shock, energy hazards, fire hazards) or damage the equipment.



Transport the device only in the antistatic original packaging or in packaging that protects it from knocks and jolts.



Only install extensions that have been released. If you install other extensions, you may interfere with the requirements and rules governing safety and electromagnetic compatibility of your system. Information on which system extensions are suitable can be obtained from the customer service center or your sales outlet.



The warranty becomes invalid if the device is damaged during the installation or replacement of system extensions.



Components can become very hot during operation. To avoid burns, make sure you do not touch components when adding or removing system board extensions!



Transmission cables to peripheral devices must be adequately shielded.

SAS 9280-8e RAID Controller

Introduction ●

Never connect or disconnect data cables during a storm (lightning hazard).

Notes about boards ●

During installation/uninstallation of a board, observe the specific instructions described in the service manual for the server.



To ensure that the system and system board are completely disconnected from the mains voltage, remove the plug from the mains outlet.



To prevent damage to boards and the components and conductors on them, please take great care when you insert or remove them. Make sure that extension boards are slotted in straight, without damaging components or conductors on the system board, or any other components, for example EMI spring contacts.



Be careful with the locking mechanisms (catches, centering pins etc.) when you replace boards.



Never use sharp objects (e.g. screw drivers) for leverage.

Environmental protection

Environmentally-friendly product design and development This product has been designed in accordance with the Fujitsu standard for "environmentally friendly product design and development". This means that key factors such as durability, selection and labeling of materials, emissions, packaging, ease of dismantling and recycling have been taken into account. This saves resources and thus reduces the harm done to the environment. Further information can be found at: – http://ts.fujitsu.com/products/standard_servers/index.html (for the EMEA market) – http://primeserver.fujitsu.com/primergy/concept/ (for the Japanese market) Energy-saving information Devices that do not need to be constantly switched on should be switched off until they are needed as well as during long breaks and after completion of work. Packaging information This packaging information doesn’t apply to the Japanese market. Do not throw away the packaging. You may need it later for transporting the system. If possible, the equipment should only be transported in its original packaging. Labels on plastic casing parts Please avoid sticking your own labels on plastic parts wherever possible, since this makes it difficult to recycle them.

Overview

The SAS 9280-8e controller is a high-performance intelligent PCI Express-toSAS/Serial ATA II adapter with RAID control capability. The SAS 9280-8e controller provides reliability, high performance, and fault-tolerant drive subsystem management. It is an ideal RAID solution for the internal storage of workgroup, departmental, and enterprise systems. The SAS 9280-8e controller offers a cost-effective way to implement RAID in a server. SAS technology brings a wealth of options and flexibility with the use of SAS and Serial ATA (SATA) II devices within the same storage infrastructure. However, SAS and SATA devices bring individual characteristics that make each one a more suitable choice depending on your storage needs. MegaRAID gives you the flexibility to combine these two similar technologies on the same controller, within the same enclosure, but not in the same virtual drive.
