16 K2 Lx0 RAID Instruction Manual July 31, 2008
Chapter 1 About the K2 Lx0 RAID
The K2 Lx0 RAID Expansion Chassis provides additional storage capacity. It
contains:
• Two Expansion Adapters
• Up to eleven K2 Lx0 RAID Expansion Chassis can be connected to a single K2
Lx0 RAID chassis
• A single disk-array storage system with up to 144 drives
K2 Lx0 RAID components
The K2 Lx0 RAID components are:
• One 2U high rack-mountable chassis
• One or two(K2 Lx0 RAID redundant) RAID controllers or two expansion adapters
(Expansion chassis)
• As many as twelve SAS 73GB or 300GB (15,000 rpm) or SATA 500 GB or 750
GB (7,200 rpm) disk drives per chassis
• Two RAID chassis power supplies
All configurations have SNMP ports, slots for primary and secondary controllers, and
chassiswith redundant power. Any unoccupied slot (RAID controller or disk module)
has a filler module to maintain air flow and compliance with electromagnetic
interference (EMI) standards.
The RAID controllers, expansion adapters, disk drives and power supplies are
hot-swappable field replaceable units (FRUs), which means you can add or replace
them while the K2 Lx0 RAID is powered up.
An optional second RAID controller module in the K2 Lx0 RAID allows for
continued access to the K2 Lx0 RAID if the primary RAID controller fails. Refer to
the K2 Storage System Instruction Manual for detailed connection and configuration
instructions.

July 31, 2008 K2 Lx0 RAID Instruction Manual 17
Chassis
The following figure shows the RAID Storage Chassis components. Details on each
component follow the figure.
NOTE: Every K2 Lx0 RAID chassis controller includes a backup battery so that if
electrical power is lost, data stored in cache memory will be saved.
Chassis
The chassis is a sheet-metal housing that contains chassis slots for the RAID
controllers or expansion adapters, disk drives, power supplies, and the LAN card.
K2 Lx0 RAID Circuit board modules
There are two circuit board modules used: the RAID controller module and the
expansion adapter. The RAID controller module is in the primary RAID chassis. It
manages the disk drives and provides an interface to the K2 Media Server system or
switch. The expansion adapter is in an Expansion chassis. It manages the disk drives,
in conjunction with the connected RAID controller and provides an SAS interface to
the primary chassis.
K2 Lx0 RAID Storage Chassis circuit board modules
The K2 Lx0 RAID includes one or two RAID controller modules. This provides
redundant host interface ports.

Chapter 1 About the K2 Lx0 RAID
The following figure shows a K2 Lx0 RAID with the two RAID controller modules.
The RAID controller module has two host ports (HP0/HP1) and two Expansion
Chassis SAS ports (DL1/DL0). The Host ports require LCC cables (optical) for the
Fibre Channel connection to a K2 Media Server or to a Fibre Channel switch. The
Expansion Chassis Ports require SAS cables for the SAS connections with a K2 Lx0
Expansion Chassis. There are two port status LEDs for each Host port and each SAS
port. Refer to “Interpreting controller status LEDs” on page 35.
When the redundant controller option is not installed in the K2 Lx0 RAID Storage
Chassis, a blank fills the other RAID controller slot.
K2 Lx0 Expansion RAID Expansion Chassis circuit board modules
The K2 Lx0 Expansion RAID Expansion Chassis has two expansion adapters as
shown in the following figure.
The expansion adapter in the K2 Lx0 Expansion has two SAS ports: DP-IN and
DP-OUT. SAS cabling connects the DP-IN port to a K2 Lx0. There aretwo port status
LEDs for each SAS port. Refer to “Interpreting expansion adapter status LEDs” on
page 38.

Power supplies
Power supplies
There are two auto-ranging power supplies, each with a power cord. Each supply
supports a fully configured K2 Lx0 External RAID and shares load currents with the
other supply, if it is present. The power supplies are designed so as to protect the disk
drives if you install them while the K2 Lx0 External RAID is powered up. A disk with
power-related faults will not adversely affect the operation of any other disk.
Each power supply has status LEDs visible from the rear panel. The status LEDs are
described in the “Interpreting power supply status LEDs” on page 39. Youcan add or
remove one power supply in the RAID Storage Chassis while the RAID Storage
Chassis is powered up, but the operationmust be completed within two minutes. Even
if a power supply is disabled, the fan in the non-functioning power supply can run off
the second power supply to cool the RAID for a couple of minutes.
Disk modules
Each disk module consists of a SAS or SATA disk drive in a carrier assembly. If a
disk drive fails, and needs replacing, you can do so while the RAID Storage Chassis
is powered up. Replacement disk drives begin rebuilding immediately after being
installed. (See “Removing and installing disk modules” on page 40.)
The following table shows how disk modules are identified based on the chassis
address and physical location. The chassis with an address set to 0 contains drives
from00to 0B; theexpansionchassisarenumberedX0throughXB, where Xindicates
the chassis number.
For information on cabling expansion chassis, see the K2 Storage System Instruction
Manual
An operating primary RAID chassis must have, at a minimum, the first three physical
drives (00 - 02) installed, as the RAID configuration information is written to these
drives. Microcode is also written to these disks when RAID controller microcode is
loaded.
The SAS and SATA disk drives are shown in the following illustrations. The SATA
drive has an adapter to fit it to the K2 Lx0 RAID Chassis.
