4. Names and Functions of Sections This section describes the sections on the disk array controller. (Front view) (Rear view)
Page 99
Used to connect a memory module or N8103-94 additional battery. N code label Indicates the N code of the disk array controller. N8103-91 PCI connector (PCI Express) The connector allows the disk array controller to be connected to a PCI slot (PCI Express)
5. Hardware Setup Install the disk array controller in a server in the following procedure. Before the installation, always refer to the User’s Guide of the server. The job flow varies depending on the server type or system configuration. Check the server type and system configuration before the installation to Check conduct setup correctly.
5-1. Prepare for setup Note the following before the setup. Only a single disk array controller can be installed in a server. Some limitation may be imposed to the installation on the PCI slot (PCI Notice Express) depending on the type of the server. Before the installation, check the limitation following the User’s Guide of the server.
5-2. Installing Additional Battery To use the N8103-94 additional battery, remove the memory module from the disk array controller, and install the additional battery instead. Open the lever fixing the memory module. Remove the memory module. Insert the additional battery into the slot securely. Close the lever opened in Step 1 to fix the battery.
5-3. Installing the Disk Array Controller Confirm the position of the PCI slot (PCI Express) in which the disk array controller is installed and remove the corresponding additional slot cover. Store the removed additional slot cover carefully. The removed screw will be used to install the disk array controller.

5-4. Connecting SAS Cable Connect the SAS cable to the SAS connector on the disk array controller. For the connection, see the figure below and the connection table. For the connection to the server, refer to the User’s Guide of the server. If it is hard to connect the cable, pull out the disk array controller from the PCI slot (PCI Express) once and connect the cable to the disk array controller.
Page 106
SAS connector SAS connector Port 4 - 7 SAS cable Port 0 - 3 Port 4 - 7 SAS cable Port 0 - 3 Example: Tower Model Server Port numbers are predefined according to the physical location of HDD. When connecting the disk array controller to the server with SAS cable, check if the cable connector is appropriate to port number.
Chapter 2 RAID This chapter describes the RAID features which the disk array controller supports. 1. Overview of RAID 1-1. What is RAID (Redundant Array of Inexpensive Disks)? RAID is an abbreviation for "Redundant Array of Inexpensive Disks". The RAID technology allows more than one hard disk drive (HDD) to be handled collectively.
1-2. RAID Levels The record mode enabling the RAID feature includes several levels. Among the levels, the disk array controller supports the following levels; RAID 0, RAID 1, and RAID 5. The number of HDDs required to create a disk group varies depending on the RAID level as shown in the table below.
1-3. Disk Group A disk group is configured with more than one HDDs. Up to eight disk groups are permitted by the disk array controller when eight HDDs are installed in the server. The figure below shows a sample configuration. The three HDDs are connected to the disk array controller, creating one disk group (DG).
1-4. Virtual Disk Virtual disk is a logical drive defined in disk group. It is recognized as a physical drive by OS. Up 40 virtual disks are permitted by the disk array controller. The figure below shows a sample configuration in which the disk array controller is connected with three HDDs, creating one disk group (DG).
1-7. Hot-Spare Disk The hot-spare disk is prepared as an auxiliary HDD substituting for a defected HDD included in a logical drive which is configured at a redundant RAID level. Detecting a HDD fault, the system disconnects the HDD (or makes it offline) and starts rebuild using the hot-spare disk.
2. RAID Levels This section details the RAID levels which the disk array controller can support. 2-1. Characteristics of RAID Levels The table below lists the characteristics of the RAID levels. Level Function Redundancy Characteristics RAID0 Striping Data read/write at the highest rate Largest capacity Capacity: (capacity of single HDD) ×...
2-3. RAID1 In the RAID1 level, data saved in a HDD is written to another HDD without change. The mode is called "mirroring". When data is written onto a single HDD, the same data is written onto another HDD. If either of the HDDs is defected, the other HDD containing the same data can substitute for the defected HDD.
2-5. Spanning of RAID1 Data to be recorded is distributed to two HDDs in mirroring mode. Then, each mirrored data is written onto HDD by striping. Owing to this feature, high disk access performance of RAID0 and, in addition, high reliability of RAID1 can be achieved. Disk array controller Disk 1 Disk 2...
For the detailed operation, refer to the "MegaRAID Storage Manager User's Guide" in NEC EXPRESSBUILDER CD-ROM that comes with the server. 1-2. Auto Rebuild The disk array controller can automatically start the rebuild without use of any utility such as MSM.
Page 116
Note the following for the rebuild: The HDD used for rebuild should have the same capacity, rotation speed, and standard as the defected HDD. Notice During rebuild, the processing rate is decreased due to much load. During rebuild, do not shutdown or reboot the server. If the server is shutdown by an unforeseen accident such as power interruption, turn on the power again as soon as possible.
If the system is restarted, Patrol Read is aborted. After restart of the system, Patrol Read runs from the first step (top of HDD). For the detailed operation, refer to the "MegaRAID Storage Manager User’s Guide" in NEC EXPRESSBUILDER CD-ROM that comes with the server. 3. Consistency Check The Consistency Check is used to check consistency among virtual drives.
4. Background Initialize The Background Initialize is automatically executed when RAID5 virtual disk is created in the disk group composing of five or more HDDs. The Background Initialize performs the parity generation processing to the area not initialized in the background. The processing is equivalent to that of Consistency Check. However, the Background Initialize is not performed in the following cases.
5. Reconstruction The reconstruction feature is used to change configuration and/or RAID level of existing virtual disk. The Reconstruction contains the following three features, however, the disk array controller supports "Migration with addition" only. 5-1. Removed physical drive Unsupported. 5-2. Migration only Unsupported.
Page 120
Note the following for the Reconstruction: Be sure to make backup copy of data and perform Consistency Check before starting Reconstruction. Notice The Reconstruction is disabled in the configuration where several virtual disks are defined in one disk group During Reconstruction, the processing rate is decreased due to much load.
Some of NEC systems cannot use mouse on WebBIOS. In that case, please use keyboard instead of mouse. Move the cursor on the screen by TAB and press Enter to select it.

Chapter 5 Operation and Maintenance 1. Maintenance Service Service representatives subordinate to or authorized by NEC provide services of the disk array controller with use of genuine parts and high technical capabilities. You can get the services for your own convenience.
3. Maintenance The disk array controller supports the following maintenance features Configuration on Disk (COD) feature Rebuild feature Critical boot feature 3-1. Configuration on Disk (COD) Feature The COD feature writes the configuration information into HDDs. The feature prevents the configuration information from being lost if the disk array controller is defected and replaced.
4. Replacement of Disk Array Controller Replace the disk array controller in the following procedure: For the handling of the server, refer to the User’s Guide of the server. Check CAUTION 高温注意 Avoid installation in extreme temperature conditions. 本体装置の電源をOFFにした直後は、内蔵型のハードディスクドライブなどをはじ め装置内の部品が高温になっています。十分に冷めたことを確認してから取り付け/ 取り外しを行ってください。...
5. Troubleshooting If the server equipped with the disk array controller does not operate normally or some utilities are disabled, check the following. Follow the action described in the relevant item if found. (1) OS cannot be installed. 8 Have virtual disks been created? Create virtual disks using WebBIOS.
Page 163
(3) HDD failed Contact your service representative. (4) Rebuild cannot be executed. 8 Is the capacity of the HDD to be rebuilt rather small, isn’t it? Use a disk having the same capacity as the defected HDD. 8 Is the RAID level of the virtual disk RAID0, isn’t it? Rebuild is not possible because of no redundancy in RAID0.
