Chapter
Introduct ion
This chapter introduces storage area network (SAN) and Fibre Channel technologies,
provides an overview of the Compaq StorageWorks SAN Director 64 (SD-64 Director or
Director), and describes the Director's capabilities and features. The Director is a second-
generation, 32-port product (expandable to 64 ports) that provides dynamic switched
connections between Fibre Channel servers and devices in a SAN environment. Directors
(from one to four) can be configured to order in a Compaq-supplied 19-inch equipment
rack. The Series 9000 and M Series racks are supported.
Directors are managed and controlled through a Compaq-supplied SANworks Director
Connectivity Manager (SDCM) server with the SDCM, SD-64 Product Manager, and
Fabric Manager applications installed. The SDCM server is a notebook personal computer
(PC) that provides a central point of control for up to 48 Directors. Multiple Directors and
the SDCM server communicate through the customer's local area network (LAN).
Figure 11 on page 12 illustrates an equipment rack with:
1 Four SD-64 Directors.
2 The shelf-mount SDCM server.
The Director implements Fibre Channel technology that provides high-performance
scalable bandwidth (one gigabit per second), highly-available operation, redundant
switched data paths, long transmission distances (up to 20 kilometers), and high device
population. The Director supports mainframe and open-systems interconnection (OSI)
computing environments, and provides data transmission and flow control between device
node ports (N_Ports) as dictated by the Fibre Channel Physical and Signaling Interface
(FC-PH 4.3).
12 SAN Director 64 Planning Guide
The Director provides dynamic switched connections for servers and devices
manufactured by multiple original equipment manufacturers (OEMs). To determine if an
OEM product can communicate through connections provided by the Director, or if
communication restrictions apply, refer to the supporting publications for the product or
contact your Compaq marketing representative.

Figure 11: Cabinet-Mount SD-64 Directors and SDCM Server
Director Overview
The Director provides high-performance port connections to end devices such as servers,
mass storage devices, and other peripherals in a Fibre Channel SAN. Up to 32 Fibre
Channel connections (expandable to 64 connections) are provided through generic ports
(G_Ports). Director software configures and supports any-to-any port connectivity.
Introduction 13
When connected to a device, a G_Port behaves as a fabric port (F_Port). When connected
to another Director (or other managed Compaq switch product) in a multi-switch fabric, a
G_Port behaves as an expansion port (E_Port).
Each fiber port module (FPM) card provides four Fibre Channel connections through
duplex small form factor (SFF) pluggable fiber-optic transceivers. The Director is
configured with eight FPM cards (32 ports), but can be upgraded through an expansion kit
to 16 FPM cards (64 ports). Three types of FPM cards are available:
An FPM card with four shortwave laser transceivers for transferring data over
multi-mode fiber-optic cable.
An FPM card with four longwave laser transceivers for transferring data over
single-mode fiber-optic cable.
A combination FPM card with three shortwave laser transceivers and one longwave
laser transceiver.
Director Performance
In addition to Fibre Channel port connectivity described above, the Director provides the
following performance features:
High bandwidth - Each port provides full-duplex serial data transfer at a rate of
1.0625 gigabits per second (Gbps).
High-availability - The Director design provides a redundant configuration of critical
hardware components with automatic failure detection and notification.
Low latency - The latency is less than two microseconds between transmission of a
frame at a source port to receipt of the frame at the corresponding destination port
(with no port contention).
Local control - Actions taking place at a device N_Port seldom affect operation of
other ports, therefore servers need to maintain little or no information about other
connected devices in a SAN.
Low communication overhead - Fibre Channel protocol provides efficient use of
transmission bandwidth, reduces interlocked handshakes across the communication
interface, and efficiently implements low-level error recovery mechanisms. This
results in little communication overhead in the protocol and a Director bit error rate
(BER) not exceeding one bit error per trillion (1012) bits.
Multiple topology support - The Director supports both point-to-point and
multi-switch fabric topologies.
14 SAN Director 64 Planning Guide
Point-to-point topology provides a single direct connection between two device
N_Ports. This topology supports bidirectional transmission between source and
destination ports. Through dynamic switching, the Director configures different
point-to-point transmission paths. In all cases, connected N_Ports use 100% of the
available bandwidth.
A multi-switch fabric topology provides the ability to connect Directors (and other
Compaq switch elements) through E_Ports and ISLs to form a Fibre Channel
fabric. Directors receive data from a device. Based on the destination N_Port
address, Directors then route the data through the fabric (and possible through
multiple switch elements) to the destination device.
Multiple service class support - The Fibre Channel signaling protocol provides
several classes of transmission service that support framing protocol and flow control
between ports. The Director supports Class 2, Class 3, and Class F services.
Class 2 transmission service provides connectionless multiplexed frame delivery
service with acknowledgment. This service duplicates the functions of a
packet-switching network, and allows multiple nodes to share links by
multiplexing the transmitted data. Multiplexing is supported from a source to
multiple destinations, or from a destination to multiple sources. Data is adaptively
transferred frame-by-frame between pairs of N_Ports through an undedicated path.
In the absence of link errors, frame delivery is guaranteed with confirmation of
receipt. Class 2 Service is best suited for mainstream computing applications.
Class 3 transmission service provides connectionless, best-effort multiplexed
datagram frame delivery with no acknowledgment. This class of service is the
same as Class 2 service; however confirmation of receipt is not given. The service
allows data transmission with great flexibility and efficiency; however, data frames
may be discarded without notification if high-traffic or error conditions are
encountered. If a data frame is discarded or corrupted, error recovery or
notification (if any) is performed at the upper level protocol (ULP) level. Class 3
service is best suited for mass storage or video applications.
Class F transmission service is connectionless service similar to Class 2 service.
This service multiplexes control frames at frame boundaries and is used by
multiple Directors to communicate across interswitch links (ISLs) to configure,
control, and coordinate the behavior of a multi-switch fabric.
Introduction 15
Director Management
Management access to the Director is provided through two Ethernet LAN connections to
the Director's control processor (CTP) cards (out-of-band management). The following
out-of-band management access methods are provided:
Management through the SDCM application. The SDCM application includes the
SD-64 Product Manager and Fabric Manager applications. This graphical user
interface (GUI) resides on the SDCM server and provides a single point of
management for all Directors. Refer to Director Software Description on page 31
for information about the applications.
Operators at remote workstations can connect to the SDCM server through the local
SDCM and SD-64 Product Manager applications to manage and monitor directors
controlled by the SDCM server. A maximum of five concurrent users (including a
local user) can log in to the SDCM application. Refer to Remote User Workstations on
page 413 for information.
Management using simple network management protocol (SNMP). An SNMP agent is
implemented through the SDCM 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 six SNMP workstations
functioning as SNMP trap message recipients.
Management through the Internet using the embedded web server 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 SD-64 Product
Manager application. Administrators launch the web server interface from a remote
PC by entering the Director's IP address as the Internet uniform resource locator
(URL), then entering a user name and password at a login screen. The PC browser then
becomes a management console.

Director Features
In addition to performance features, and out-of-band management, the Director provides:
High-availability features.
Connectivity features.
Security features.
Serviceability features.
High-Availability Features
Pairs of critical field-replaceable units (FRUs) installed in the Director provide
redundancy in case a FRU fails. When an active FRU fails, the backup FRU takes over
operation automatically (failover) to maintain Director and Fibre Channel link operation.
NOTE: FPM cards do not automatically fail over and provide link operation after a failure. To
continue operation, Fiber-optic cables from the failed FPM card must be disconnected and
reconnected to ports on a spare card.
Introduction 17
A standard availability Director has all possible FRUs installed and is fully redundant.
Standard redundancy is provided through dual sets of FRUs and spare (unused) ports on
FPM cards.
CTP cards - The Director contains two CTP cards. The redundant CTP card provides
a backup connection to the SDCM server and ensures continued Director operation if
the active CTP card fails.
SBAR assemblies - The Director contains two serial crossbar (SBAR) assemblies. The
redundant serial SBAR assembly ensures uninterrupted transmission and receipt of
Fibre Channel frames between ports if the active SBAR card fails.
Power supplies - The Director contains two power supplies that share the electrical
operating load. If one power supply fails, the other supply handles the full load.
Separate receptacles at the rear of the Director provide facility input power to each
supply. For full redundancy, input power for each receptacle should come from a
different source.
Fan modules - The Director contains two fan modules, each containing three fans (six
fans total). If one or more fans in a module fail, the redundant fan module provides
cooling until the failed module is replaced. If the second fan module fails, software
shuts off power to the Director to prevent system damage.
Ports - The Director is delivered with eight FPM cards (32 ports). Any unused Fibre
Channel port can be used in place of a failed port. To continue device operation, the
fiber-optic cable from a failed port is reconnected to an unused operational port.
Additional FPM cards (up to 16 total cards) can be installed to provide spare or
additional Fibre Channel port connections.
Connectivity Features
The Director and associated SDCM application support the following Fibre Channel
connectivity features:
Any-to-any connectivity - Director software configures hardware routing tables for
each source port to provide any-to-any port connectivity. Subject to user-defined
restrictions (port blocking and zoning), the tables define the destination ports with
which the source port is allowed to communicate.
Extended distance support - Through the use of repeaters, any Director port can be
configured for extended distance operation. By setting a port's buffer-to-buffer credit
(BB_Credit) value to 60, the port can transmit data up to 100 kilometers.
18 SAN Director 64 Planning Guide
Port blocking - System administrators can block or unblock any Director port through
the SDCM application. Blocking a port prevents an attached device from logging in to
the Director or communicating with any attached device. A blocked port continuously
transmits an offline sequence (OLS).
Zoning - System administrators can partition attached devices into restricted-access
zones. Devices in the same zone can recognize and communicate with each other
through switched port-to-port connections. Devices in separate zones cannot recognize
and communicate with each other.
Broadcast and multi-cast support - The Director supports transmission of a Fibre
Channel frame to all attached N_Ports (broadcast), or transmission of a Fibre Channel
frame to a user-specified group of attached N_Ports (multi-cast).
State change notification - The Director supports a state change notification function
that allows attached N_Ports to request notification when other N_Ports change
operational state.
Port binding - The Director supports a feature (enabled through an optional feature
key) that binds an attached Fibre Channel device to a specified Director port through
the device's world wide name (WWN).
Security Features
The SDCM application offers the following security features:
Password protection - Users must provide a user name and password to log in to the
SDCM server and access managed Directors. Administrators can configure user names
and passwords for up to 16 users, and can authorize or prohibit specific management
permissions for each user.
Remote user restrictions - Remote user access to Directors is either disabled or
restricted to configured IP addresses.
SNMP workstation restrictions - SNMP workstations can only access management
information base (MIB) variables managed by the Director SNMP agent. SNMP
workstations must belong to SNMP communities configured through the SDCM
application. If configured, the agent can send authorization failure traps when
unauthorized SNMP workstations attempt to access the Director.
Audit log tracking - Configuration changes to the Director are recorded in an audit
log stored on the SDCM server, where they are accessible to users for display. Log
entries include the date and time of the configuration change, a description of the
change, and the source of the change.
Introduction 19
Port blocking - System administrators can block or unblock any port to restrict device
access to the Director.
Zoning - System administrators can create zones that provide Director access control
to increase network security, differentiate between operating systems, and prevent data
loss or corruption. Zoning can be implemented in conjunction with server-level access
control and storage device access control.
Serviceability Features
The Director and SDCM application offer the following serviceability features:
Light-emitting diodes (LEDs) on Director FRUs and the front bezel that provide visual
indicators of hardware status or malfunctions.
System alerts, event logs, audit logs, link incident logs, and hardware logs that display
Director, Ethernet link, and Fibre Channel link status at the SDCM server.
Diagnostic software that performs power-on self tests (POSTs) and port diagnostics
(internal loopback and external loopback tests).
Automatic notification of significant system events (to support personnel or
administrators) through alphanumeric pager, e-mail messages, or the call-home
feature.
NOTE: Call-home notification requires installation of Compaq Proactive Service software. This
service is offered at no additional charge for subsystems covered under an on-site warranty or
on-site storage hardware support contract. To register or order Proactive Service software,
contact your Compaq customer service representative.
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 IP
address, subnet mask, and gateway address. The port also allows service personnel to
run diagnostics and isolate system problems through a local or remote terminal.
Redundant FRUs (logic cards, power supplies, and cooling fans) that are removed or
replaced without disrupting Director or Fibre Channel link operation.
A modular design that enables quick removal and replacement of FRUs without the
use of special tools or equipment.
FPM cards are added or replaced and fiber-optic cables are attached to ports without
interrupting other ports or Director operation.
110 SAN Director 64 Planning Guide
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 SD-64 Product Manager application 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 SDCM 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 MIB that runs on the SDCM server. Up
to 12 authorized management workstations can be configured through the SDCM
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 1.10),
transmission control protocol/internet protocol (TCP/IP) MIB-II definition (RFC
1213), or a product-specific MIB that run on each Director. Up to six authorized
management workstations can be configured through the SD-64 Product Manager
application to receive unsolicited SNMP trap messages. The trap messages indicate
operational state changes and failure conditions.

Director Hardware Description 23
Cable Management Assembly
The cable management assembly at the bottom front of the Director provides routing for
Ethernet cables attached to CTP cards and fiber-optic cables attached to Director ports.
The assembly rotates up to provide front access to the redundant power supplies.
Front Bezel
The bezel at the top front of the Director includes an amber system error LED and a green
power LED. The power LED illuminates when the Director is powered on and operational.
If the LED extinguishes, a facility power source, alternating current (AC) power cord, or
Director power distribution failure is indicated.
The system error LED illuminates when the Director detects an event requiring immediate
operator attention, such as a FRU failure. The LED remains illuminated as long as an
event is active. The LED extinguishes when the Clear System Error Light function is
selected from the SD-64 Product Manager application. The LED blinks if unit beaconing
is enabled. An illuminated system error LED (indicating a failure) takes precedence over
unit beaconing.
CTP Card
The Director is delivered with two CTP cards. The active CTP card initializes and
configures the Director after power on and contains the microprocessor and associated
logic that coordinate Director operation. A CTP 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 both CTP cards without switching off power or
affecting operational fiber-optic links.
Each CTP card also provides a 10/100 megabit per second (Mbps) RJ-45 twisted pair
connector on the faceplate that attaches to a customer-supplied Ethernet local area
network (LAN) to communicate with the SDCM server or a simple network management
protocol (SNMP) management station.
Each CTP card provides system services processor (SSP) and embedded port (EP)
subsystems. The SSP subsystem runs Director applications and the underlying operating
system, communicates with Director ports, and controls the RS-232 maintenance port and
10/100 Mbps Ethernet port. The EP subsystem provides Class F and exception frame
processing, and manages frame transmission to and from the SBAR assembly. In addition,
24 SAN Director 64 Planning Guide
a CTP card provides nonvolatile memory for storing firmware, Director configuration
information, persistent operating parameters, and memory dump files. Director firmware
is upgraded concurrently (without disrupting operation).
The backup CTP card takes over operation if the active card fails. Failover from a faulty
card to the backup card is transparent to attached devices.
Each card faceplate contains a green LED that illuminates if the card is operational and
active, and an amber LED that illuminates if the card fails. Both LEDs are extinguished on
an operational backup card. The amber LED blinks if FRU beaconing is enabled.
FPM Card
Each FPM card provides four full-duplex generic ports (G_Ports) that transmit or receive
data at 1.0625 gigabits per second (Gbps). G_Port functionality depends on the type of
cable attachment. FPM cards use non-open fiber control (OFC) 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 behave 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 node port
(N_Port).
If the G_Port is attached to another Director or switch 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.
Single-mode or multi-mode fiber-optic cables attach to FPM cards through small form
factor (SFF) pluggable optical transceivers. The fiber-optic transceivers provide duplex
LC connectors, and can be detached from FPM cards (through a 10-pin interface) for easy
replacement. Two fiber-optic transceiver types are available:
Shortwave Laser - Shortwave laser transceivers provide connections for transferring
data over short distances (2 to 500 meters) through 50-micron or 62.5-micron
multi-mode fiber.
Longwave Laser - Longwave laser transceivers provide connections for transferring
data over long distances (up to 20 kilometers) through 9-micron single-mode fiber.
Director Hardware Description 25
Figure 23 illustrates the faceplate of an FPM card. The card faceplate contains:
1 An amber LED (at the top of the card) that illuminates if any port fails or blinks if FRU beaconing is
enabled.
2 A bank of amber and green LEDs above the ports. One amber LED and one green LED are associated
with each port and indicate port status as follows:
The green LED illuminates (or blinks if there is active traffic) and the amber LED
extinguishes to indicate normal port operation.
The amber LED illuminates and the green LED extinguishes to indicate a port failure.
Both LEDs extinguish to indicate a port is operational but not communicating with an
N_Port (no cable attached, loss of light, port blocked, or link recovery in process).
The amber LED flashes and the green LED either remains on, extinguishes, or flashes to
indicate a port is beaconing or running online diagnostics.
3 Four duplex LC connectors for attaching fiber-optic cables.

Figure 23: FPM Card LEDs and Connectors
26 SAN Director 64 Planning Guide
The Director is delivered with eight FPM cards installed (32 ports), but provides chassis
slots for up to 16 FPM cards (64 ports total). An FPM card is a concurrent FRU and can be
added or replaced while the Director is powered on and operating.
Power Supply
Redundant, load-sharing power supplies step down and rectify facility input power to
provide 48-volt direct current (VDC) power to Director FRUs. The power supplies also
provide overvoltage and overcurrent protection. Either power supply can be replaced
while the Director is powered on and operational.
Each power supply has a separate backplane connection to allow for different AC power
sources. The power supplies are input rated at 85 to 264 volts alternating current (VAC).
The faceplate of each power supply provides the following status LEDs:
A green PWR OK LED illuminates if the power supply is operational and receiving
AC power.
An amber FAULT LED illuminates if the power supply fails.
An amber TEMP LED illuminates if the power supply shuts down due to an over
temperature condition.
An amber I LIM LED illuminates if the power supply is overloaded and operating at
the current limit (15.6 amperes).
Power Module Assembly
The power module assembly is located at the bottom rear of the Director. The module is a
nonconcurrent FRU, and the Director must be powered off prior to scheduled removal and
replacement. The module provides:
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 is overheated.
Two single-phase AC power connectors. Each connector is input rated at 85 to 264
VAC.
A 9-pin maintenance port that provides a connection for a local workstation or dial-in
connection for a remote workstation. Although the port is typically used by
maintenance personnel, operations personnel use the port to configure network
addresses.
Director Hardware Description 27
An input filter and AC system harness (internal to the FRU) that provides the wiring to
connect the AC power connectors to the power switch and power supplies (through the
backplane).
Fan Module
Two fan modules, each containing three fans (six fans total), provide cooling for Director
FRUs, as well as redundancy for continued operation if a fan fails.
The fan module can be replaced while the Director is powered on and operating, provided
the module is replaced within ten minutes (after which software powers off the Director).
An amber LED for each fan module illuminates if one or more fans fail or rotate at
insufficient angular velocity.
SBAR Assembly
The Director is delivered 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. Failover
to the backup assembly is transparent to attached devices.
Each SBAR assembly mounts flush on the backplane, and the FRU comprises the card and
a steel carriage. 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 illuminates if the assembly is operational and active,
and an amber LED that illuminates if the assembly fails. Both LEDs are extinguished on
an operational backup assembly. The amber LED blinks if FRU beaconing is enabled.
Backplane
The backplane provides 48 VDC power distribution and connections for all logic cards.
The backplane is a nonconcurrent FRU. The Director must be powered off prior to FRU
removal and replacement.

SDCM Server Description
The SDCM server is a notebook personal computer (PC) that provides a central point of
control for up to 48 LAN-connected Directors. The server is mounted in a slide-out drawer
in the Compaq-supplied cabinet. The SDCM server (or Internet access to the Director's
embedded web server application) is required to install, configure, and manage the
Director. Although the Director operates normally without an SDCM server, the server is
required to monitor Director operation, log events and configuration changes, and report
failures. Figure 24 illustrates the SDCM server.

Figure 24: SDCM Server
The SDCM server is dedicated to operation of the SDCM, SD-64 Product Manager, and
Fabric Manager applications. The applications provide a graphical user interface (GUI)
and management services, and implement Web and other server functions. Refer to
Director Software Description on page 31 for information about the applications.
Director Hardware Description 211
NOTE: The SDCM server and SDCM application provide a GUI to monitor and manage multiple
Compaq Directors, and are a dedicated hardware and software solution that should not be used
for other tasks. Compaq tests the SDCM application installed on the SDCM server, but does not
compatibility test other third-party software. Modifications to the SDCM server hardware or
installation of additional software (including patches or service packs) may interfere with normal
operation.
United States English is the only language supported by the server keyboard and the
SDCM, SD-64 Product Manager, and Fabric Manager applications.
The SDCM server provides an auto-detecting 10/100 Mbps LAN connector. This
connection is provided through a personal computer memory card international
association (PCMCIA) slot at the right side of the server. The server attaches to the
customer-supplied LAN segment containing Directors.

Remote User Workstations
Operators at remote workstations with the client SDCM application installed can connect
to the SDCM server to manage and monitor all Directors controlled by the server. A
maximum of four concurrent remote users (plus the local SDCM server user) can log in to
the SDCM application. The client application downloads and installs to remote
workstations (from the SDCM server) using a standard web browser. The applications
operate on platforms that meet the following minimum system requirements:
Desktop or notebook PC with color monitor, keyboard, and mouse, using an Intel
