Chapter 1

About the K2 Level 3 RAID storage

This chapter introduces the K2 RAID Storage. Topics include:

• “Level 3 RAID features” on page 15

• “Level 3 RAID components” on page 17

• “Configurations” on page 23

Level 3 RAID features

The K2 Level 3 RAID Stor age is used in Level 3 and Level 3R K2 Storage Systems.
The RAID storage device is a high performance, high availability mass storage
system. The L3 RAID chassis 2Gb/s host interface supports industry standard Fibre
Channel technology.

L3 RAID
Expansion
Chassis

L3 RAID
Chassis

November 23, 2005 Level 3 RAID Instruction Manual 15

Chapter 1 About the K2 Level 3 RAID storage

Four FC host ports are available, so that the L3 RAID chassis can be connected
directly to up to four media servers without Fibre Channel switches. The L3 RAID
chassis utilizes dual FC-AL technology, allowing four loop configurations within a
single chassis. Port-BypassCircu its have been ad ded to maint ain loop integ rity during
failures without user intervention. Each loop and associated Port Bypass Circuits
along with all other active components are on redundant, separate hot swappable
modules. With two RAID Controllers, the two loops within a single standard chassis
are configured as a single loop with a backup loop in standby mode.

High-performance RAID processors that enable inter-controller communication at
2Gb/s are installed to implement the shared memory system. This feature not only
enhances the performance, but also helps dynamic load balancing of the host
interfaces.

The Switch based disk enclosures permits hi gh- speed access to the d isk dr ive s being
used.

The L3 RAID chassis cont ains from fi fteen low prof ile 3.5" Fi bre Channel Ar bitrated
Loop (FC-AL) disk drives. The chassis also supports one or two hardware RAID
Controllers in one 3U high rack-mountable chassis.

The L3 RAID Expansion Chassis provides additional storage capacity. The
Expansion Chassis has one or two Expansion Adapters installed. Up to seven L3
RAID Expansion Chassis can be connected to a single L3 RAID chassis comprising
a single disk-array storage system with up to 120 drives.

NOTE: Grass Valley does not support mix ing disk drives of differing capaciti es in
a file system stripe group.

K2 Level 3 features

The K2 Level 3 provides 350 MB/s maximum data rate. Optical cables connect to
hosts, such as to a K2 Media Server or to a Fibre Channel switch.

The Level 3 RAID suppor ts up to seven K2 Level 3 RAID Expans ion Chassis. It does
not support connection to PFC500E, PFR500E, PFR600E, or PFR700E RAID
Expansion Chassis .

Capacity and redundancy

The level 3 RAID contains five, ten, or fifteen low profile 3.5" Fibre Channel
Arbitrated Loop (FC-AL) di sk drives . The chassis a lso suppor ts one or t wo hardware
RAID controllers in one 3U high rack-mountable chassis. The Level 3 RAID
currently uses 73GB, 146GB or 300GB drive capacit ies. Wit h 15 drives, one chassis
holds up to 876GB, 1.7TB, or 3.6TB depending on the disk drive option.

The Level 3 Expansion Chassis provides additional storage capacity. Up to seven
Level 3 Expansion Chassis can be connected to a single K2 RAID Storage Chassis
comprising a single disk-array storage system with a total of 120 drives and
approximately 1.7TB, 3.4TB, 7.2TB of storage depending on the disk drive option.
This provides for cost effective storage expansion as requirements grow.

16 Level 3 RAID Instruction Manual November 23, 2005

Level 3 RAID components

The Level 3 RAID components are:

• The chassis with passive midplane board

• One or two RAID controllers (K2 Level 3R) or two expansion adapters

• As many as fifteen Fibre Channel disk drives per chassis

• Two RAID chassis power supplies (K2 Level 3) or expansion chassis power
supplies

Any unoccupied slot (RAID c ontroller or disk mo dule) has a filler modu le to maintain
air flow and compliance w ith electromagnetic interference (EMI) standar ds.

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 Level 3 RA ID is powere d up.

IMPORTANT: You must not hot swap operational RAID controllers or disk drives
without first disa bling th e target compo nent usin g the Grass Vall ey Stora ge Util ity.

An optional second RAID controller module in the Level 3 RAID, allows for
continued access to the Level 3 RAID if the primary RAID controller fails. Refer to
the K2 Storage System Instruc tion Manual f or detail ed conn ectio n and config urati on
instructions.

must have its chassis a ddress manuall y configured. This address i s set by a cont rol on
the expansion adapter. Refer to your K2 Storage System Instruction Manual for
information on setting the chassis address switch. See also, “Addressing

requirements” on page 26.

The following diagram shows how disk modules are identified based on the chassis
address and physical location. The chassis with an address set to 0 contains drives
from 00 to 0E; the expansion chassis with an address se t to 1 contains drives from 10
to 1E.

Disk modules

Each disk module consists of a Fibre Channel 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 43.)

The disk drives are 3.5-inch FC-AL drives that conform to the Fibre Channel
Arbitrated Loop (FC-AL) standards and support dual-port FC-AL interconnects
through the two RAID controllers and their cabling.

November 23, 2005 Level 3 RAID Instruction Manual 19

Chapter 1 About the K2 Level 3 RAID storage

NOTE: Once the Level 3 RAID is installed and configured, the disk

!

modules become slot dependent. Moving disk modules between physical
slots will result in loss of data and t he need to rec onfigure th e system.

Level 3 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 a Fibre Channel interface to the K2 Media
Server system or Fibre Channel switch fabric. The expansion adapter is in an
Expansion chassis. It manages the disk drives, in conjunction with the connected
RAID controller and provides a Fi bre Channel interface to the primary chassis.

Level 3 RAID Storage Chassis circuit board modules

The K2 Level 3R includes one or two RAID controller modules. This provides
redundant Fiber Channel interface ports.

The following figure shows a K2 Level 3 RAID Storage Cha ssi s with the two RAID
controller modules installed.

The RAID controller module has four Fibre Channel ports: two Host Fibre Channel
Ports (HP0/HP1) and two Expansion Chassis Ports (DL1/DL0). The Host Fibre
Channel Ports require LCC cables (o ptica l) for the Fibre Ch annel connec tion to a K2
Media Server or to a Fibre Channel switch. The Expansion Chassis Ports require
HSSDC cables (copper) for the Fibre Chan nel connections with a Level 3 Expansion
Chassis. This extends the Fibre Channel loop of the corresponding K2 Level 3
chassis. There i s a port status LED f or each Fibr e Channel por t. Refer t o “Interpreting

controller status LEDs” on page 39.

When the redundant Fiber Channel option is not installed in the K2 Level 3 RAID

Power supplies

There are two auto-ranging power supplies, power cord and standby switch. Each
supply supports a fully configured K2 Level 3 External RAID and shares load
currents with the o the r su ppl y, if it is present. The power sup pli es are designed so as
to protect the disk drives if you install them while the K2 Level 3 External RAID is
powered up. A disk with power-related faults will not adversely affect the operation
of any other disk.

The RAID chassis and the expansion chassis each have their own type of power
supply. The two types are not interchangeable.

Level 3 RAID Installation Information

This chapter describes information you’ll need to install th e K2 RAID Sto rage (K2
Level 3 Expansion Chassis). Major topics are:

• “Installation requirements”

• “Installing a K2 Level 3 RAID Storage in an equipment rack”

• “K2 Level 3 RAID Storage power-up and initialization”

• “K2 Level 3 RAID Storage power-down”

Installation requir ements

This section describes the following requirements:

• “Site requirements” on page 25

• “Addressing requirements” on page 26

• “Cabling requirements” on page 26

• “Binding disk modules into groups” on page 27

Site requirements

For proper K2 Level 3 Expansion Chassis operation, the installation site must
conform to certain environmental specifications. These are detailed below and in

Chapter 4, Level 3 RAID Technical Specifications and Operating Limits.

Power

Refer to “Data handling specifications ” on page 55 for AC power requirements. The
values indicate eit her the values for the power cord of a K2 Level 3 Expansion Chassis
with a single power supp ly, or the total values shared by the line cords of two power
supplies in the same K2 Level 3 Expansion Chassis, with the division between the
power cords and supplies at the current sharing ratio. If one of the two power suppli es
fails, the remaining supply and cord must support the full load. You must use a rack
mount cabinet with ac power distribution, and have main branch ac distribution that
can handle these values for the number of K2 Level 3s and K2 Level 3 Expansion
Chassis units that you will interconnect.

Cooling

Make sure your si te has air condition ing of the correct s ize and pla cement to mai ntain
the specified ambient te mperatu re range. The air cond itio ning must be able to handle
the requirements of the K2 Level 3s and any connected Level 3 Expansions as
indicated under “Environmental limits” on page 56.

November 23, 2005 Level 3 RAID Instruction Manual 25

Chapter 2 Level 3 RAID Installation Information

Addressing requirements

There are two addresses for the K2 Level 3: the Fibre Channel Arbitrated Loop
address ID (FC-AL addre ss ID) and t he chassis address. I f you have a c ustom syste m
that needs multiple primary RAID chassis connected to an FC switch, consult your
Grass Valley representative.

Chassis address setting requirement

The chassis address for a K2 Level 3 primary RAID chassis is pre-set at 0 and does
not need to be configured.

Each Level 3 Expansion expansion chassi s must have its chassi s address configu red.
This is set by the chassis address switch, which is located on the expansion adapter.
The following figure identifies the switch.

(4) LINKUP LED

(1) READY LED

(2) FAULT LED

Set the switch as explained in the K2 Storage System Instruction Manual.

NOTE: When the switches of the left and right adapters are set differently, the
FAULT LEDs blink and the Expansion ch assis is not started. If different values a re
set, turn off the power of the system including the Expansion chassis, re-set the
values to

1, and turn on the power again.

Cabling requirements

It is recommended that you use th e Fibre Channel cable s shipped with your K2 Level
3 Expansion Chassis when making connections. For cable specifications, refer to

“Cable lengths” on page 55.

Optical cables must meet the app ropriate 2-Gbit FC-AL loo p standards. You must use
this type of cable to connect a host to the K2 Level 3 controller.

(6) Ejector

Copper cables must meet the appropriate standards for 2-Gbit FC-AL loops. You
must use this type of cable to connect Expansion chassis.

Do not leave an unused (that is, dangling) cable connected to a Fibre Channel port
because it may cause excess noise on the loop.

NOTE: Also refer to the K2 Storage System Instruction Manual for cabling
diagrams and step-by-step instructions.

26 Level 3 RAID Instruction Manual November 23, 2005

Binding disk modules into groups

After cabling a K2 Level 3 and a ny Level 3 Expansion s, you must bind disk modules
into LUNs using the Storage Utility provided by Grass Valley. Refer to the K2
Storage System Instruction Manual for information on using the Storage Utility to
bind drives.

NOTE: Make sure you allow adequate time for binding disk modules into LUNs.
K2 Level 3 RAID controllers bind multiple LUNs at the same time, yet take more
than an hour to bind a LUN. Large drive capacities and multiple LUNs can
increase the binding tim e to 10 hours or more.

K2 Level 3 RAID Storage power-up and
initialization

This section gives information about connecting power and powering-on the
K2 Level 3 RAID Storage system.

Connecting electrical cables

For each chassis, there are two electrical cables (one for each power supply) that
should be connected to separate outside power sources.

!

!

To prevent the plug from being inadvertently discon nected, secure the electri cal cable
into the outlet by doing the following:

1. Check that the power switch on the RAID chassis and tho se on the host system are

all set to OFF.

WARNING: Make sure the power cords meet local safety and elec trical
standards.

CAUTION: The K2 Level 3 RAID Storage system must be electrically
grounded. Operating the syst em without proper grounding can dama ge
disk drives. If the outlet you use is not grounded, make sure that a
licensed electrician replaces it and installs a grounding conductor.

2. Insert the power cord into the power supply.

3. Secure the power cord with the stopper.

4. Insert the plug of the power cord into an AC outlet. Use a grounded AC outlet.

Powering-up the K2 Level 3 RAID Storage system

1. Power-up the Level 3 Expansi on Expansio n chas sis prio r to or at the s ame time as

the K2 Level 3 Controller chassis.

NOTE: You must always power-up the Level 3 Expansion Expansion chassis prior
to, or at the same time as, the K2 Level 3 RAID controll er chassi s. Failure to do so
may prevent some LUNs in the expansion chassis from being recognized.

November 23, 2005 Level 3 RAID Instruction Manual 33

Chapter 2 Level 3 RAID Installation Information

Before turning on the AC power, c heck f or loos e d isk drive s by pus hing e ach disk
drive.

2. Turn on power switches on both power supplies.
When turning on the power switches, confirm that the POWER GOOD LEDs

(green) on all th e po wer supplies and POWER LEDs (green) on the front panel of
the RAID chassis and Expansion chassis go on. The power supply starts, and the
POWER LED (green) is on while the power switches are on.

The RAID chassis performs the self-test and initialization immediately after the
power is turned on. When the self-test and initialization terminate and the RAID
chassis becomes ready , the READY LED of the controller stop s flashing and enters
the on state.

3. Confirm that the READY LED is on, and then turn on the host system.
The chassis takes four minutes (at maximum) to start.
Refer to sections in Chapter 3, “Servicing the Level 3 RAID” for information on

interpreting status LED behavior.

NOTE: Refer to the K2 Storage System Instruction Manual for complete system
power-up procedures.

K2 Level 3 RAID Storage power-down

NOTE: If your K2 Level 3 RAID Storage system is part of a shared storage sys tem,
refer to the K2 Storage Syst em Instruction Manual for instructions on shutting down
the shared storage before powering down a K2 Level 3 RAID Storage.

To power-down the K2 Level 3 RAID Storage correctly:

1. Stop all read/write activity to th e K2 Level 3 RAID Storage storage system.

2. On the RAID controller chassis, turn off power switches on both power supplies.

3. On the Expansion chassis, turn off both power switches on both power supplies.
Alternatively, turn off all power switches of the RAID controller chassis and the

Expansion chassis at the same time.

!

To turn on power, refer to “K2 Level 3 RAID Storage power-up and initiali zation” on

page 33.

CAUTION: You must always power down the K2 Level 3 RAID
controller chass is prior to, or at the same ti me as the Level 3 Expansion
Expansion Chassis.

Servicing the Level 3 RAID

This chapter des cri be s how to monitor K2 Level 3 External RAID status and r eplace
Field Replaceable Units (FRU).

Topics include:

• “Maintenance procedures using Grass Valley Storage Utility” on page 35

• “Monitoring K2 Level 3 External RAID status using NetCentral” on page 35

• “Interpreting disk module LEDs” on page 38

• “Interpreting controller status LEDs” on page 39

• “Interpreting power supply status LEDs” on page 43

• “Removing and installing disk modules” on page 43

• “Replacing a RAID controller or expansion adapter” on page46

• “Replacing a power supply” on page 49

Maintenance procedures using Grass Valley Storage Utility

Several maintenance procedures can be performed using the Grass Valley Storage
Utility.

To perform the following tasks, refer to the K2 Storage System Instruction Manual:

• Checking RAID controller microcode version

• Loading RAID controller microcode

• Identifying disk modules prior to removal

• Downloading K2 Level 3 disk drive firmware

• Disabling a K2 Level 3 RAID controller for removal

• Disabling a K2 Level 3 disk module for removal

• Configuring K2 Level 3 network and SNMP settings

Monitoring K2 Level 3 External RAID status using NetCentral

You can mon itor K2 Level 3 External R AID Storage systems us ing Grass Valley’s
NetCentral monitoring software. Enabled by SNMP, NetCentral can continuously
monitor the storage system and send notifications if there is a problem. The SNMP
agent software required for NetCentral monitoring resides on the RAID storage
device itse lf. As a resul t, the K2 Level 3 External RAID appears in NetCentral as a
standalone device rather than as a subsystem of the K2 Media Client.

November 23, 2005 Level 3 RAID Instruction Manual 35

Chapter 3 Servicing the Level 3 RAID

Communication with NetCentral takes place over the Ethernet connection on each
RAID controller. To monitor the K2 Level 3 External RAID, you must connect
network cabling, power on the sys tem, then configur e network and SNMP sett ings as
described in the K2 Storage System Instruction Manual.

Refer to the N etCentral On-line Help for information on monitoring the Level 3
RAID with NetCentral.

Removing and installing disk modules

!

Use the following instructions to replace a faulty disk module. It should be replaced
while the RAID chassis is running (hot-swapped).

Moving disk modules

!

• The disk module must be unbound.

• Moving a drive module that is part of a LUN to anot her slot makes all informati on
on the LUN inaccessible.

• You must remove and install the di sk module while the storag e system is powered
up.

CAUTION: If the RAID chassis does not have the r edundant controller
option, when a replacement disk module is inserted there can be a 1.5
second (maximum) disruption. Video record/play is not affected.

CAUTION: You can destroy the media file system beyond recovery if
you move a disk module to a different sl ot. The service person can move
a disk module when you don’t care about losing the media in the media
file system and under the following cautions:

November 23, 2005 Level 3 RAID Instruction Manual 43

Chapter 3 Servicing the Level 3 RAID

A disk module must be inserted all the way or removed entirely. Do not leave a disk
module partially removed exce pt for periods when you are allowing it to spin down.
When replacing multiple disks, observe the following:

• The RAID chassis configuration information is w ritten to the first three disk
modules. If all of th ese disk modules are rep laced with new device s with the power
supplies turned off, the information is lost. This condition is indicated by the
SERVICE LED blinking at a high rate at chassis power up. Therefore, do not
replace the first three disk modules with the power supplies turned off.

• When multiple disk modules are subject to replacement, they must be replaced
with new disk modules one by one. Do not replace multiple disk modules
simultaneously. After checking th at the Ready L ED on the front panel of the
current disk module is lit, commence replacing the next disk module.

• Stick on the physical label indicating the installation position on each newly
installed disk module.

!

CAUTION: Handle a disk module gently and use an ESD wristband.
Do not remove a faulty disk module until you have a replacement
module (with the same part number) or a filler module available.

Removing a disk module

NOTE: If a disk module has been bound into a LUN, do not mov e it to another slot
unless you do not care about the data on the LUN. Each module has LUN
identifying information written wh en it is bound. Moving it to another slot can
make information on the original LUN inaccessible.

Generally, you should not remove a disk module unless it is faulty. Refer to

“Interpreting front panel LEDs” on page 36 and “Monitoring K2 Level 3 External
RAID status using NetCentral” on page 35.

NOTE: If you wish to remove an operational disk module, use the Grass Valley
Storage Utility to disable the disk before removing it.

To remove the disk module:

1. Confir m the location of the faulty disk module by checking its Fault LED. Also
check NetCentral messages. NetCentral messages may report disk faults by disk
module number.

2. Remove the disk module as illustrated in the following diagram.

Replacing a RAID controller or expansion adapter

Use the following instructions to replace a RAID controller or expansion adapter. It
should be replaced while the chassis is powered up (hot-swapped).

On a chassis with two controllers, if the controller microcode on the replacement
controller is not the same as that on the other currently installed controller, the
microcode on the r eplacement con troller is a utomatica lly upgraded or downgraded t o
match that on the currently installed controller.

NOTE: A Level 3 RAID chassis must have at least one RAID controller installed.
Do not remove both RAID controllers, even in an offline condition. Since the
controllers store the configuration information of the RAID chassis or the product
license unlock information, replacing the two controllers simultaneously loses the
data.

Removing a RAID controller or expansion adapter

To remove a RAID controller or expansion adapter:

1. Identify the module to be replaced using NetCentral or verify that the module’s
Fault LED is on. If you are removing an operatio nal RAID controller, use the Grass
Valley Storage Utility to disable th e RAID controller.

2. Remove the cables connect ed to the module. No te wher e the c ables connect to t he
