Features
System board
The features of the system board (D1409) are described in the technical manual
for the system board in relation to the hardware and in the BIOS setup manual
for the firmware (see “Related Publications” on page 107).
Hot-plug PCI slots
In addition to standard PCI slots, the server also comprises two hot-plug PCI
slots that allow boards to be installed and removed online assuming the
operating system supports this functionality (for further information see section
“Replacing hot-plug PCI Boards” on page 94).
Hard disk drives
The server has a drive cage that can accommodate up to six ULTRA 320-SCSI
hard disk drive modules. Each hard disk drive module (HDD module) can accom-
modate a SCSI hard disk drive with an SCA (Single Connector Attachment)
interface and a maximum height of 1 inch. The module is connected to the SCSI
backplane without cables via the SCA interface. This allows hard disk drive
modules to be simply plugged in or pulled out (for further details see section “Hot-
swap Hard Disk Drives” on page 81).
The hard disk drive system is designed for Ultra3 SCSI and can be configured
as a dual-channel system with three hard disk drives each or as a single-
channel system with six hard disk drives. The hard disk drives can be controlled
by the onboard controller or by a RAID controller.
A HDD extension box can be installed optionally (with a maximum of three HDD
modules). The hard disk drives in the extension box can likewise be controlled
by the onboard controller or by a RAID controller.
If the server has a RAID controller and a corresponding RAID configuration,
defective HDD modules can also be exchanged online (hot-swap).
An external SCSI interface is also offered optionally to allow external storage
subsystems to be connected. You find further information in the configurator
(see “Related Publications” on page 107).
