4. Names and Functions of Sections This section describes the components of the disk array controller. Disk Array Controller (Front view) (Rear view) Channel 1 (Ports 0 and 1) connector The connector allows the disk array controller to be connected to the backplane board. N code label Indicates the N code of the disk array controller.
Backplane Board (Front View) (Rear View) SAS connector The connector allows the backplane board to be connected to the HDD. Card edge connector The connector allows the disk array controller to be connected to the server. Internal connector The connector allows the backplane board to be connected to the disk array controller. Internal Cable Mounting Screws (3)
Chapter 2 RAID This chapter describes the RAID features that 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." RAID technology allows more than one HDD to be handled collectively.
1-3 Disk Group A disk group is configured with more than one HDD. Up to two disk groups are permitted by the disk array controller when two HDD‟s are installed in the server. The figure below shows a sample configuration. Two HDD‟s are connected to the disk array controller, creating one disk group (DG).
2. RAID Levels This section details the RAID levels that the disk array controller supports. 2-1 Characteristics of RAID Levels The table below lists the characteristics of the RAID levels: Level Function Redundancy Characteristics RAID0 Striping Fastest data read/write Largest capacity Capacity: (capacity of single HDD) ×...
2-3 RAID1 In RAID1, data saved to a HDD is written to another HDD without change. This mode is called "mirroring." When data is written to a single HDD, the same data is written to another HDD. If either of the HDD‟s fails, the other HDD containing the same data can substitute for the failed HDD.
Select a HDD and start the rebuild manually. For the detailed operation, refer to the "MegaRAID Storage Manager User's Guide" on the NEC EXPRESSBUILDER CD-ROM that comes with the server. 1-2 Auto Rebuild The disk array controller can automatically start the rebuild without using a utility such as MSM.
(top of HDD). For the detailed operation, refer to the "MegaRAID Storage Manager User‟s Guide" on the NEC EXPRESSBUILDER CD-ROM that comes with the server. 3. Consistency Check Consistency check is used to check the consistency among virtual drives. It is available for redundant virtual drives in RAID1.
5. Reconstruction The reconstruction feature is used to change the configuration and/or RAID level of an existing virtual disk. 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 98
Ex: Migration with addition for RAID0 virtual disk The figure below shows an example of adding a single 36GB HDD to a RAID0 virtual disk configured with a single 36GB HDD: Virtual disk (RAID0) [Before execution] Capacity = 36GB 36GB 36GB Execute Migration with addition Virtual disk (RAID1)
Chapter 4 Hardware Setup Install the disk array controller in a server in the following procedure. Before 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 installation to perform the Check setup correctly.
1. Prepare for Setup Note the following before the setup: Only a single disk array controller can be installed in a server. Some limitations may be imposed on the installation to the mezzanine slot depending on the type of the server. Before installation, check the limitations by referring to the Notice User‟s Guide of the server.
2. Installing the Disk Array Controller This section describes how to install the disk array controller in the server, using N8400-029F/030F NEC Express5800/120Bb-6 as an example. The disk array controller does not support the PCI hot-plug feature. Before installing or removing the disk array controller from the server, always remove the server from the Blade Enclosure.
Page 102
Lift the rear cover to remove it from the CPU blade. Locate the mezzanine slot (Type 2) to install the disk array controller. Insert the disk array controller straight into the mezzanine card slot (Type 2), and then secure it with the provided screws.
Page 103
Install the backplane board. (1) If a HDD has been installed in the server, remove it. (2) Remove the four screws from the front cover. (3) Lift the front cover straight up to remove it. (4) If a backplane board has been installed, remove it. Remove the three screws to remove the existing backplane board.
Page 104
(5) Install the new backplane board. Secure the backplane board with the three screws removed in the previous step. (6) Install the front cover. Pay attention to the engagement of the connectors. (7) Tighten the four screws at both sides of the front cover.
Page 105
Connect the internal cable to the two connectors on the disk array controller. See the figure below. If it is difficult to connect the cable, remove the disk array controller from the mezzanine card slot (Type 2) and connect the cable to the disk array controller. Connector at backplane Internal cable Connector at server side...

3. Maintenance The disk array controller supports the following maintenance features: Configuration on Disk (COD) Rebuild Critical boot 3-1 Configuration on Disk (COD) Feature The COD feature writes the configuration information on a HDD. 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 Avoid installation in extreme temperature conditions. Immediately after the server is powered off, its internal components such as HDD‟s are very hot.
