Overview
Director Description
The director is a second-generation, 64-port product that provides dynamic
switched connections between Fibre Channel servers and devices in a SAN
environment. Directors are managed and controlled through an High Availability
Fabric Manager (HAFM) appliance with HAFM and Director 2/64 Element
Manager installed. The HAFM appliance is a 1U rack-mount appliance that
provides a central point of control for up to 48 directors and/or edge switches.
Multiple directors and the HAFM appliance communicate through the customer’s
local area network (LAN).
Features
Features of the Director 2/64 include:
■Scalable from 32 to 64 User ports (with optional UPM 2 Gb add-on)
■100% dynamic non-blocking, cut through switching with congestion queuing
■Online error detection, error isolation, and error recovery
■Redundant, hot-pluggable components
■Full duplex 200 MB/sec per port performance
■Less than 2-µs average switch latency
■100-km distance support (60 buffers), with use of repeaters
■Small form factor, hot-pluggable optical transceivers, auto configure G_ports
■Combination short-wave or long-wave laser transceivers
■Redundant power supplies and fan modules
■Online product repair for Field Replaceable Units (FRUs)
■Periodic health check and enhanced system monitoring
■Non-disruptive firmware load and update
18Director 2/64 Installation Guide
Director Management
The director is managed and controlled through:
■The HAFM application. This graphical user interface (GUI) resides on the
HAFM appliance and provides a single point of management for all directors,
and a launching point for the Director 2/64 Element Manager.
■Simple network management protocol (SNMP). A SNMP agent is
implemented through the HAFM application that allows administrators on
SNMP management workstations to access director management information
using any standard network management tool. Administrators can assign
internet protocol (IP) addresses and corresponding community names for up
to 12 SNMP workstations functioning as SNMP trap message recipients.
Refer to the HP StorageWorks SNMP Reference Guide for Directors and Edge Switches for more information.
■The Internet using the Embedded Web Server (EWS) interface installed on
the director. This interface supports configuration, statistics monitoring, and
basic operation of the director, but does not offer all the capabilities of the
Director 2/64 Element Manager. Administrators launch the EWS interface
from a remote PC by entering the director’s IP address as the internet URL,
then entering a user name and password at a login screen. The PC browser
then becomes a management console.
Overview
Note: The default user name for the right to view status and other information is
“operator.” The default user name for the right to modify configuration data,
perform maintenance tasks, or perform other options is “Administrator.” The
default password for both user names is “password.”
■The command line interface (CLI). The CLI allows you to access many
HAFM and Element Manager functions while entering commands during a
telnet session with the director. The primary purpose of the CLI is to automate
management of a large number of directors using scripts. The CLI is not an
interactive interface; no checking is done for pre-existing conditions and no
prompts display to guide users through tasks. Refer to the HP StorageWorks CLI Reference Guide for Directors and Edge Switches for more information.
■A customer-supplied PC or UNIX-based platform with the HAFM appliance
and client HAFM and Director Element Manager installed.
■A customer-supplied remote workstation communicating with the HAFM
appliance through a corporate intranet.
19Director 2/64 Installation Guide
Overview
■A customer-supplied PC platform with a network connection to the EWS
interface installed on the director.
■A customer-supplied server platform communicating with the switch through
a LAN or corporate intranet. The HAFM applications are ordered and
installed on the server by the customer.
Error-Detection, Reporting, and Serviceability
The director provides the following error-detection, reporting, and serviceability
features:
■Light-emitting diodes (LEDs) on director FRUs and the front bezel that
provide visual indicators of hardware status or malfunctions.
■System and threshold alerts, event logs, audit logs, link incident logs,
threshold alert logs, and hardware logs that display director, Ethernet link, and
Fibre Channel link status at the HAFM appliance, remote workstation, or
EWS.
■Diagnostic software that performs power-on self-tests (POSTs) and port
diagnostics (internal loopback, external loopback, and Fibre Channel (FC)
wrap tests). The FC wrap test applies only when the director is configured to
operate in FICON management style.
■An internal modem for use by support personnel to dial in to the HAFM
appliance for event notification and to perform remote diagnostics.
■Automatic notification of significant system events (to support personnel or
administrators) through e-mail messages or the call-home feature at the
HAFM appliance.
Note: The call-home feature is not available through the EWS interface.
■An RS-232 maintenance port at the rear of the director (port access is
password-protected) that enables installation or service personnel to change
the director’s internet protocol (IP) address, subnet mask, and gateway
address.
■Redundant FRUs—logic cards, power supplies, and cooling fans—that are
removed or replaced without disrupting director or Fibre Channel link
operation.
20Director 2/64 Installation Guide
Overview
■A modular design that enables quick removal and replacement of FRUs
without tools or equipment.
■Concurrent port maintenance—UPM cards are added or replaced and
fiber-optic cables are attached to ports without interrupting other ports or
director operation.
■Beaconing to assist service personnel in locating a specific port, FRU, or
director in a multi-switch environment. When port beaconing is enabled, the
amber LED associated with the port flashes. When FRU beaconing is
enabled, the amber (service required) LED on the FRU flashes. When unit
beaconing is enabled, the system error indicator on the front bezel flashes.
Beaconing does not affect port, FRU, or director operation.
■Data collection through the Element Manager on the HAFM appliance to help
isolate system problems. The data includes a memory dump file and audit,
hardware, and engineering logs.
■Status monitoring of redundant FRUs and alternate Fibre Channel data paths
to ensure continued director availability in case of failover. The HAFM
application queries the status of each backup FRU daily. A backup FRU
failure is indicated by an illuminated amber LED.
■SNMP management using the Fibre Alliance management information base
(MIB) Version 3.1, that runs on the HAFM appliance. Up to 12 authorized
management workstations can be configured through the HAFM application
to receive unsolicited SNMP trap messages. The trap messages indicate
operational state changes and failure conditions.
■SNMP management using the Fibre Channel Fabric Element MIB (Version
1.1), transmission control protocol/internet protocol (TCP/IP) MIB-II
definition (RFC 1213), or a product-specific MIB that runs on each director.
Up to six authorized management workstations can be configured through the
Element Manager on the HAFM appliance to receive unsolicited SNMP trap
messages. The trap messages indicate operational state changes and failure
conditions.
Note: For more information about SNMP support provided by HP products, refer
to the

21Director 2/64 Installation Guide
Overview
Zoning
The director supports a name server zoning feature that partitions attached devices
into restricted-access groups called zones. Devices in the same zone can recognize
and communicate with each other through switched port-to-port connections.
Devices in separate zones cannot communicate with each other.
Zoning is configured by authorizing or restricting access to name server
information associated with device N_Ports that attach to director fabric ports
(F_Ports). A zone member is specified by the port number to which a device is
attached, or by the eight-byte (16-digit) World Wide Name (WWN) assigned to
the host bus adapter (HBA) or Fibre Channel interface installed in a device. A
device can belong to multiple zones.
Caution: If zoning is implemented by port number, a change to the director
fiber-optic cable configuration disrupts zone operation and may incorrectly
include or exclude a device from a zone.
If zoning is implemented by WWN, removal and replacement of a device
HBA or Fibre Channel interface (thereby changing the device WWN) disrupts
zone operation and may incorrectly include or exclude a device from a zone.
In Open Fabric mode, only zoning by WWN is supported. Zoning by port
numbers is not supported.
Zones are grouped into zone sets. A zone set is a group of zones that is enabled
(activated) or disabled across all directors and edge switches in a multi-switch
fabric. Only one zone set can be enabled at one time.
Multi-Switch Fabrics
A Fibre Channel topology that consists of one or more interconnected directors or
switch elements is called a fabric. Operational software provides the ability to
interconnect directors (through expansion port (E_Port) connections) to form a
multi-switch fabric. The data transmission path through the fabric is typically
determined by fabric elements and is user-transparent. Subject to zoning
restrictions, devices attached to any interconnected director can communicate
with each other through the fabric.
Because a multi-switch fabric is typically complex, maintenance personnel should
be aware that several factors can degrade fabric performance or cause
connectivity failures. These factors include:
22Director 2/64 Installation Guide
Overview
■Domain ID assignment—Each director in a fabric is identified by a unique
domain ID that ranges from 1 through 31. A domain ID of 0 is invalid. If two
operational fabrics join, they determine if any domain ID conflicts exist
between the fabrics. If one or more conflicts exist, the E_Ports that form the
interswitch link (ISL) segment to prevent the fabrics from joining.
■Zoning—In a multi-switch fabric is configured on a fabric-wide basis, and a
change to the zoning configuration is applied to all directors and switch
elements in the fabric. To ensure zoning is consistent across a fabric, the
following rules are enforced when two fabrics (zoned or unzoned) join:
— Fabric A unzoned and Fabric B unzoned—The fabrics join
successfully, and the resulting fabric remains unzoned.
— Fabric A zoned and Fabric B unzoned—The fabrics join successfully,
and fabric B automatically inherits the zoning configuration from
fabric A.
— Fabric A unzoned and Fabric B zoned—The fabrics join successfully,
and fabric A automatically inherits the zoning configuration from
fabric B.
— Fabric A zoned and Fabric B zoned—The fabrics join successfully only
if the zone configurations can be merged. If the fabrics cannot join, the
connecting E_Ports segment and the fabrics remain independent.
Zone configurations for two fabrics are compatible (the zones can join) if the
active zone set name is identical for each fabric, and if zones with the same
name have identical elements.
■Port segmentation—When an ISL activates, directors exchange operating
parameters to determine if they are compatible and can join to form a single
fabric. If they are incompatible, the connecting E_Port at each director
segments to prevent the creation of a single fabric. A segmented link transmits
only Class F traffic; the link does not transmit Class 2 or Class 3 traffic. The
following conditions cause ports to segment:
— Incompatible operating parameters—Either the resource allocation
timeout value (R_A_TOV) or error detect timeout value (E_D_TOV) is
inconsistent between directors. To prevent E_Port segmentation, the same
E_D_TOV and R_A_TOV must be specified for each director.
— Duplicate domain IDs—One or more domain ID conflicts are detected.
— Incompatible zoning configurations—Zoning configurations for the
directors are not compatible.
23Director 2/64 Installation Guide
Overview
— Build fabric protocol error—A protocol error is detected during the
process of forming the fabric.
— No principal switch—No director in the fabric is capable of becoming
the principal switch.
— No response from attached switch—After a fabric is created, each
director in the fabric periodically verifies operation of all attached
switches and directors. An ISL segments if a switch or director does not
respond to a verification request.
— ELP retransmission failure timeout—A director that exhibits a
hardware failure or connectivity problem cannot transmit or receive Class
F frames. The director did not receive a response to multiple exchange
link protocol (ELP) frames, did not receive a fabric login (FLOGI) frame,
and cannot join an operational fabric.
Hardware Components
The Director provides a modular design that enables quick removal and
replacement of FRUs. The following sections define Director 2/64 main
components.

The Director 2/64 ships with two Control Processor (CTP2) cards. The active
CTP2 card initializes and configures the director after power on, and contains the
microprocessor and associated logic that coordinate director operation. The
second CTP2 card serves as a backup. A CTP2 card provides an Initial Machine
Load (IML) button on the faceplate. When the button is pressed and held for three
seconds, the director reloads firmware and resets the CTP2 card without switching
off power or affecting operational fiber-optic links.
Each CTP2 card also provides a 10/100 megabit per second (Mbps) RJ-45 twisted
pair connector on the faceplate that attaches to an Ethernet Local Area Network
(LAN).
25Director 2/64 Installation Guide
Overview
Each CTP2 card provides System Services Processor (SSP) and Embedded Port
(EP) subsystems. The SSP subsystem runs director applications, communicates
with director ports, and controls the RS-232 maintenance port and 10/100 Mbps
ethernet port. The EP subsystem provides Class F processing, and manages frame
transmission to and from the Serial Crossbar Assembly (SBAR). In addition,
CTP2 cards provide non-volatile memory for storing firmware director
configuration information, persistent operating parameters, and memory dump
files. Director firmware is upgraded concurrently (without disrupting operation).
Each card faceplate contains a green light emitting diode (LED) that turns O

Power Supplies
The Director 2/64 uses redundant, load-sharing power supplies which step down
and rectify facility input power to provide 48-VDC power to Director FRUs. The
power supplies also provide over-voltage and over-current protection. Either
power supply can be replaced while the switch is powered on and operational.
Each power supply has a separate backplane connection to allow for different AC
power sources.
26Director 2/64 Installation Guide
UPM Card
Overview
The power supplies are input rated at 85 to 264 VAC. The faceplate of each power
supply provides the following status LEDs:
■A green PWR OK LED turns ON if the power supply is operational and
receiving AC power.
■An amber FAU LT LED turns ON if the power supply fails.
■An amber TEMP LED turns ON if the power supply shuts down due to an
over temperature condition.
■An amber I LIM LED turns ON if the power supply is overloaded and
operating at the current limit (15.6 A).
Power supply requirements are listed in Appendix B.
Each Universal Port Module (UPM) card provides four full-duplex generic ports
(G_Ports) that transmit or receive data at 1.063 or 2.125 gigabits per second
(Gbps). G_Port functionality depends on the type of cable attachment. UPM cards
use Non-Open Fiber Control (NOFC) Class 1 laser transceivers that comply with
Section 21 of the Code of Federal Regulations (CFR), Subpart J as of the date of
manufacture.
Depending on device connections, G_Ports work as follows:
■If the G_Port is attached to a Fibre Channel device, the port functions as a
fabric port (F_Port). An F_Port is the interface on a director that connects to a
device N_Port.
■If the G_Port is attached to another director to form an Interswitch Link (ISL),
the port functions as an expansion port (E_Port). A multi-switch fabric is
formed through multiple directors and ISLs.

Overview
SBAR Assembly
The director ships with two SBAR assemblies. The active SBAR is responsible for
Fibre Channel frame transmission from any director port to any other director
port. Connections are established without software intervention. The assembly
accepts a connection request from a port, determines if a connection can be
established, and establishes the connection if the destination port is available. The
assembly also stores busy, source connection, and error status for each director
port.
The backup SBAR takes over operation if the active assembly fails, and provides
the ability to maintain connectivity and data frame transmission without
interruption. The transition to the backup assembly is transparent to attached
devices.
Each SBAR assembly consists of a card and steel carriage that mounts flush on
the backplane. The carriage provides protection for the back of the card,
distributes cooling airflow, and assists in aligning the assembly during installation.
The rear of the carriage contains a green LED that turns O
operational and active, and an amber LED that turns O

The power module assembly is located at the bottom rear of the director. The
module provides the following.
■Two single-phase AC power connectors. Each connector is input rated at 85 to
264 VAC.
■A power switch (circuit breaker) that controls AC power distribution to both
power supplies. The breaker is set manually, or is automatically tripped by
internal software if thermal sensors indicate the director has overheated.
■A 9-pin maintenance port that provides a connection for a local terminal or
dial-in connection for a remote terminal.
