Chapter
General Information
The Compaq StorageWorks SAN Director 64 (SD-64 Director or Director) provides
dynamic switched connections between Fibre Channel servers and devices in a storage
area network (SAN) environment. SANs introduce the concept of server-to-device
networking and multiswitch fabrics, eliminate requirements for dedicated connections,
and enable the enterprise to become data-centric. A SAN provides speed, high capacity,
and flexibility for the enterprise, and is primarily based upon Fibre Channel architecture.
The Director implements Fibre Channel technology that provides scalable bandwidth
(1.0625 gigabits per second), redundant switched data paths, and long transmission
distances (up to 20 kilometers).
This chapter describes the Director and attached SANworks Director Connectivity
Manager (SDCM) server. The chapter specifically discusses:
Director management, error detection and reporting features, serviceability features,
zoning, multiswitch fabrics, and specifications.
The SDCM server and minimum hardware specifications.
Maintenance approach.
Remote workstation configurations and hardware specifications.
Field-replaceable units (FRUs).
Software diagnostic features.
Tools and test equipment.
12 SAN Director 64 Service Manual
Director Description
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 9000 or M-series equipment rack.
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 13 illustrates an equipment rack with
1 Four SD-64 Directors.
2 The shelf-mount SDCM server.
General Information 13
Figure 11: Cabinet-Mount SD-64 Directors and SDCM Server
The Director provides dynamic switched connections for servers and devices, 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). Through
interswitch links (ISLs), the Director can also connect to one or more additional Directors
to form a Fibre Channel multiswitch fabric.
14 SAN Director 64 Service Manual
Director Management
Management access to the Director is provided through an Ethernet LAN connection to
the Director's control processor (CTP) cards (out-of-band management), or as an optional
feature, a Fibre Channel connection to an FPM card (inband management). The following
out-of-band management access methods are provided:
Management through the SDCM application. This graphical user interface (GUI)
resides on the SDCM server and provides a single point of management for all
Directors, and a launching point for the SD-64 Product Manager and Fabric Manager
applications.
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.
Management through a customer-supplied remote workstation communicating with
the SDCM Server through a corporate intranet.
Figure 12 on page 15 illustrates out-of-band Director management. The figure shows
the following elements connected through a customer-supplied intranet:
1 SNMP management workstation.

Error-Detection, Reporting, and Serviceability Features
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 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 or on a
remote workstation.
Diagnostic software that performs power-on self-tests (POSTs) and port diagnostics
(internal loopback and external loopback).
Automatic notification of significant system events (to support personnel or
administrators) through e-mail messages or the call-home feature.
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; or 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.
16 SAN Director 64 Service Manual
A modular design that enables quick removal and replacement of FRUs without the
use of special tools or equipment.
Concurrent port maintenance. FPM 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
multiswitch 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 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.
Simple network management protocol (SNMP) using the Fibre Alliance management
information base (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 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 runs on each Director. Up to six authorized management
workstations can be configured through the Product Manager application to receive
unsolicited SNMP trap messages. The trap messages indicate operational state changes
and failure conditions.
Zoning Feature
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.
General Information 17
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 Director port number to which a device is attached, or by the
8-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.
Zones are grouped into zone sets. A zone set is a group of zones that is enabled (activated)
or disabled across all Directors and switches in a multiswitch fabric. Only one zone set can
be enabled at one time.
Multiswitch Fabrics
A Fibre Channel topology that consists of one or more interconnected Director or switch
elements is called a fabric. Operational software provides the ability to interconnect
Directors [through expansion port (E_Port) connections] to form a multiswitch 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 multiswitch fabric is typically complex, maintenance personnel should be
aware that several factors can degrade fabric performance or cause connectivity failures.
These factors include:
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 multiswitch fabric, zoning is configured on a fabric-wide basis, and a
change to the zoning configuration is applied to all Directors in the fabric. To ensure
zoning is consistent across a fabric, the following rules are enforced when two fabrics
(zoned or unzoned) join:
18 SAN Director 64 Service Manual
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
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 time-out value
(R_A_TOV) or error-detect time-out 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.
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.

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 or other managed products. Figure 13
illustrates the SDCM server.
The server is mounted in a slide-out drawer in the Compaq-supplied 9000 or M-series
(H9A10 or H9A15) equipment rack. The SDCM server or Internet access to the embedded
web server interface is required to install, configure, and manage the Director.
Although a configured Director operates normally without SDCM server intervention, an
attached server should operate at all times to monitor Director operation, log events and
configuration changes, and report failures.
Figure 13: SDCM Server
112 SAN Director 64 Service Manual
The SDCM server provides an auto-detecting 10/100 Mbps LAN connector, provided by
an Ethernet adapter card installed in the personal computer memory card international
association (PCMCIA) slot at the left side of the PC. The adapter card attaches to the LAN
segment containing the Directors and to a customer intranet to allow access from remote
user workstations.
NOTE: The SDCM laptop server is connected to the customer intranet using the external
Ethernet card on the left side of the PC (the PCMCIA slot). The Ethernet connection on the rear of
the PC is not currently used.
SDCM Server Specifications
The following list summarizes hardware specifications for the SDCM server notebook
platform. Current platforms may ship with more enhanced hardware, such as a faster
processor, additional random- access memory (RAM), or a higher-capacity hard drive or
removable disk drive.
Notebook PC with color monitor, keyboard, and keyboard- mounted trackpad (mouse).
Intel Celeron processor with a 600 megahertz (MHz) or greater clock speed, running
the Microsoft Windows NT 4.0 operating system.
2-gigabyte (GB) or greater internal hard drive.
128-megabyte (MB) or greater RAM.
CD-ROM drive.
1.44-MB 3.5-inch disk drive.
100-MB external disk (Zip) drive.
Two 10/100 Mbps Ethernet adapters with RJ-45 connectors.
Ethernet Hub (Optional)
The SDCM server and managed Directors can connect through a customer-provided
cabinet-mounted 10/100 Base-T Ethernet hub.
General Information 113
Embedded Web Server Interface
Administrators or operators with a browser-capable PC and an Internet connection can
monitor and manage the Director through an embedded web server interface. The
application provides a graphical user interface (GUI) similar to the Product Manager
application, and supports Director configuration, statistics monitoring, and basic
operation.
Maintenance Approach
Whenever possible, the Director maintenance approach instructs service personnel to
perform fault isolation and repair procedures without degrading or interrupting operation
of the Director, attached devices, or associated applications. Director fault isolation begins
when one or more of the following occur:
System event information displays at the attached SDCM server, a remote workstation
communicating with the SDCM server, or the embedded web server interface.
LEDs on the Director front bezel or FRUs illuminate to indicate a hardware
malfunction.
An unsolicited SNMP trap message is received at a management workstation,
indicating an operational state change or failure.
Notification of a significant system event is received at a designated support center
through an e-mail message or the call-home feature.
System events can be related to a:
Director or SDCM server failure (hardware or software).
Ethernet LAN communication failure between the Director and SDCM server.
Link failure between a port and attached device.
ISL failure or segmentation of an E_Port.
Fault isolation and service procedures vary depending on the system event information
provided. Fault isolation and related service information is provided through maintenance
analysis procedures (MAPs) documented in Chapter 2. MAPs consist of step-by-step
procedures that prompt service personnel for information or describe a specific action to
be performed. MAPs provide information to interpret system event information, isolate a
Director failure to a single FRU, remove and replace the failed FRU, and verify Director
operation. The fault isolation process normally begins with MAP 0000: Start MAP on
page 22.
114 SAN Director 64 Service Manual
Ensure the correct Director is selected for service (if the SDCM server manages multiple
Directors or other Compaq products) by enabling unit beaconing at the failed Director.
The amber system error LED on the Director front bezel blinks when beaconing is
enabled. Instructions to enable beaconing are incorporated into MAP steps.
Remote Workstation Configurations
Customer system administrators determine whether to allow access to Directors from
remote workstations. If administrators allow remote sessions, they may restrict access to
selected workstations by configuring the IP addresses of those workstations through the
SDCM application. When a remote session is allowed, the remote user has the same rights
and permissions as if the session were on the local SDCM server. Up to five SDCM
application sessions can be simultaneously active (one local and four remote).
Remote workstations must have access to the customer intranet (LAN segment) on which
the SDCM server is installed. Director administrative functions are accessed through the
LAN and SDCM server. The customer intranet is part of the 10/100 Mbps LAN that
provides access to managed Directors. This Director-to-SDCM server connection is part
of the equipment rack installation and is required. Connection of remote workstations
through the customer intranet is optional. This type of network configuration using an
Ethernet connection through the SDCM server is shown in Figure 14.

If the SDCM server connection is provided through the customer intranet, all functions
provided by the SDCM server are available to users throughout the enterprise.
To optimize security, it is recommended that the SDCM server and all Directors reside in a
secure physical network domain for storage and servers in the information technology (IT)
enterprise.
NOTE: The Ethernet adapter in the SDCM server provides an auto-detecting 10/100 Mbps
connection.
