Compaq ProLiant Servers
Compaq industry standard servers are a primary component of all models of
Compaq ProLiant Clusters. At the high end of the ProLiant server line, several
high availability and manageability features are incorporated as a standard part
of the server feature set. These include online backup processors, a PCI bus
with hot-plug capabilities, redundant hot-pluggable fans, redundant processor
power modules, redundant Network Interface Controller (NIC) support,
dual-ported hot-pluggable 10/100 NICs and redundant hot-pluggable power
supplies (on most high-end models). Many of these features are available at
the low end and mid range of the Compaq ProLiant server line, as well.
Compaq has logged thousands of hours testing multiple models of Compaq
servers in clustered configurations and has successfully passed the Microsoft
Hardware Cluster Certification Test Suite on numerous occasions. In fact,
Compaq was the first vendor to be certified using a shared storage subsystem
connected to ProLiant servers through Fibre Channel Arbitrated Loop
technology.
NOTE: Visit the Compaq High Availability website
(http://www.compaq.com/highavailability) to obtain a comprehensive list of
cluster-certified servers.
The Microsoft Cluster Software (MSCS) is based on a cluster architecture
known as shared storage clustering, in which clustered servers share access to
a common set of hard drives. MSCS requires all clustered (shared) data to be
stored in an external storage system.
The Compaq StorageWorks RA4000/4100 storage system is the shared storage
system for the Compaq ProLiant Clusters HA/F100 and HA/F200.
Compaq StorageWorks RAID Array 4000 or Compaq
StorageWorks RAID Array 4100
The Compaq StorageWorks RAID Array 4000 Compaq StorageWorks RAID
Array 4100 (RA4000/4100) is the storage cabinet that contains the disk drives,
power supplies, and array controllers. The RA4000/4100 supports the same
hot-pluggable drives as Compaq Servers and Compaq ProLiant Storage
Systems, online capacity expansion, online spares, and RAID fault tolerance
of SMART-2 Array Controller technology. The RA4000/4100 also supports
hot-pluggable, redundant power supplies and fans, and hot-pluggable hard
drives.
Architecture of the Compaq ProLiant Clusters HA/F100 and HA/F200 1-7
The HA/F100 and HA/F200 ProLiant Clusters must have at least one
RA4000/4100 set up as an external shared storage. Consult the Order and
Configuration Guide for Compaq ProLiant Cluster HA/F100 and HA/F200 at
the Compaq ProLiant Clusters High Availability website
(http://www.compaq.com/highavailability) to determine the maximum supported
cluster configuration.
For more detailed information on the RA400/4100, refer to the following
documents:
■ Compaq StorageWorks RAID Array 4000 User Guide
■ Compaq StorageWorks RAID Array 4100 User Guide
Compaq StorageWorks RAID Array 4000 Controller
The Compaq StorageWorks RAID Array 4000 Controller (RA4000
Controller) is fully RAID capable and manages all of the drives in the
RA4000/4100 storage array. Each RA4000/4100 is shipped with one controller
installed. In a HA/F100 cluster, each array controller is connected to both
servers through a single Fibre Channel storage hub or FC-AL switch. In a
HA/F200 cluster, the addition of a second Compaq StorageWorks RA4000
Redundant Controller is required to provide redundancy.
These redundant controllers are connected to each server through two separate,
and redundant, Fibre Channel storage hubs or FC-AL switches. This
dual-connection configuration implements a vital aspect of the enhanced high
availability features of the HA/F200 cluster. Each of these components is
discussed in the following sections. For more information, refer to the Compaq
StorageWorks RAID Array 4000 Redundant Array Controller Configuration
Poster.
For more information about shared storage clustering, refer to the Microsoft
clustering documentation.
1-8 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide
Connection Infrastructure for the RA4000/4100
The servers in a Compaq ProLiant Cluster HA/F100 and HA/F200 are
connected to one or more RA4000/4100 shared external storage systems using
industry-standard Fibre Channel Arbitrated Loop (FC-AL) technology. The
components used to implement the Fibre Channel Arbitrated Loop include
shortwave (multi-mode) fiber optic cables, Gigabit Interface
Converters-Shortwave (GBIC-SW) and Fibre Channel storage hubs or FC-AL
switches.
Compaq StorageWorks Fibre Channel Storage
Hubs
The Compaq StorageWorks Fibre Channel Storage Hub is a critical
component of the FC-AL configuration and allows up to five RA4000/4100s
to be connected to the cluster servers in a “star” topology. For the HA/F100, a
single hub is used. For the HA/F200, two redundant Fibre Channel storage
hubs are used. Either the 7-port or 12-port hub may be used in either type of
cluster.
If the maximum number of supported RA4000/4100s (currently five) are
connected to either type of cluster using a 12-port hub, there will be unused
ports. Compaq does not currently support using these ports to connect
additional RA4000/4100s. Other FC-AL capable devices, such as tape backup
systems, should not be connected to these unused ports under any
circumstances.
For more information, refer the following guides:

■ Compaq StorageWorks Fibre Channel Storage Hub 12 Installation
Guide
Compaq StorageWorks FC-AL Switch 8
The Compaq StorageWorks FC-AL Switch 8 is the core component of an
affordable storage area network (SAN) solution that will consolidate storage,
simplify storage management, manage explosive data growth, and reduce
business downtime. The FC-AL Switch 8 is a high-performance, switch
engine, interconnect component that will help you take that important step
towards building a low cost SAN. Built on the stable, easy to use, and mature
FC-AL protocol, the FC-AL Switch 8 offers eight ports with dedicated
non-blocking 100 MB/second point-to-point parallel connections.
Architecture of the Compaq ProLiant Clusters HA/F100 and HA/F200 1-9
Using the StorageWorks FC-AL Switch 8 as the cornerstone of your SAN
deployment, you can start by combining your primary storage components,
such as the RA4000/RA4100 storage systems and secondary storage
Enterprise Backup Solution components, such as tape libraries
(TL890/TL891/TL895) on the same departmental SAN. With a 12Gbps switch
engine, the StorageWorks FC-AL Switch 8 delivers the necessary resiliency
and speed to isolate your client-server network from heavier storage network
traffic. Furthermore, as your connection needs grow, the 8-port StorageWorks
FC-AL Switch 8 can be expanded to 11 ports using the StorageWorks FC-AL
Switch 3-Port Expansion Module.
The StorageWorks FC-AL Switch 8 can be easily managed using management
tools such as StorageWorks Command Console (SWCC), Compaq Insight
Manager -XE (CIM-XE), Compaq Insight Manager (CIM), Array
Configuration Utility (ACU), and the StorageWorks Switch Management
Utility.
For more information, refer to the Compaq StorageWorks Fibre Channel
FC-AL Switch 8 Installation Guide.

Gigabit Interface Converter-Shortwave
Two Gigabit Interface Converter-Shortwave (GBIC-SW) modules are required
for each Fibre Channel cable installed. Two GBIC-SW modules are provided
with each RA4000/4100, RA4000 Controller, and host bus adapter.
GBIC-SW modules hot-plug into Fibre Channel storage hubs, array
controllers, and host bus adapters. These converters provide ease of expansion
and 100 MB/s performance. GBIC-SW modules support distances up to
500 meters using multi-mode fibre optic cable.
Cluster Interconnect
The cluster interconnect is a data path over which nodes of a cluster
communicate. This type of communication is termed intracluster
communication. At a minimum, the interconnect consists of two network
adapters (one in each server) and a cable connecting the adapters.
The cluster nodes use the interconnect data path to:
■ Communicate individual resource and overall cluster status
■ Send and receive heartbeat signals
■ Update modified registry information
IMPORTANT: MSCS requires TCP/IP as the cluster communication protocol. When
configuring the interconnects, be sure to enable TCP/IP.
Client Network
Every client/server application requires a local area network, or LAN, over
which client machines and servers communicate. The components of the LAN
are no different than with a stand-alone server configuration.
Because clients desiring the full advantage of the cluster will now connect to
the cluster rather than to a specific server, configuring client connections will
differ from those for a stand-alone server. Clients will connect to virtual
servers, which are cluster groups that contain their own IP addresses.
Within this guide, communication between the network clients and the cluster
is termed cluster-to-LAN communication.

Private or Public Interconnect
There are two types of interconnect paths:
■ A private interconnect (also known as a dedicated interconnect) is used
solely for intracluster (node-to-node) communication. Communication
to and from network clients does not occur over this type of
interconnect.
■ A public interconnect not only takes care of communication between the
cluster nodes, it also shares the data path with communication between
the cluster and its network clients.
For more information about Compaq-recommended interconnect strategies,
refer to the White Paper, “Increasing Availability of Cluster Communications
in a Windows NT Cluster,” available from the Compaq High Availability
website (
http://www.compaq.com/highavailability).
Interconnect Adapters
Ethernet adapters, or Compaq ServerNet™ adapters, can be used for the
interconnect between the servers in a Compaq ProLiant Cluster. Either
10Mb/sec, or 100Mb/sec, Ethernet may be used. ServerNet adapters have
built-in redundancy and provide a high-speed interconnect with 100MB/sec
aggregate throughput.
Ethernet adapters can be connected together using an Ethernet crossover cable
or a private Ethernet hub. Both of these options provide a dedicated
interconnect.
Implementing a direct Ethernet or ServerNet connection minimizes the
potential single points of failure.

Redundant Interconnects
To reduce potential disruptions of intracluster communication, use a redundant
path over which communication can continue if the primary path is disrupted.
Compaq recommends configuring the client LAN as a backup path for
intracluster communication. This provides a secondary path for the cluster
heartbeat in case the dedicated primary path for intracluster communications
fails. This is configured when installing the cluster software, or it can be added
later using the MSCS Cluster Administrator.
It is also important to provide a redundant path to the client LAN. This can be
done by using a second NIC as a hot standby for the primary client LAN NIC.
There are two ways to achieve this, and the method you choose is dependent
on your hardware. One way is through use of the Redundant NIC Utility
available on all Compaq 10/100 Fast Ethernet products. The other option is
through the use of the Network Fault Tolerance feature designed to operate
with the Compaq 10/100 Intel silicon-based NICs. These features allow two
NICs to be configured so that one is a hot backup for the other.
For detailed information about interconnect redundancy, refer to the Compaq
White Paper, “Increasing Availability of Cluster Communications in a
Windows NT Cluster,” available from the Compaq High Availability website
(
http://www.compaq.com/highavailability).
Cables
Three general categories of cables are used for Compaq ProLiant HA/F100
and HA/F200 clusters:
Server to Storage
Shortwave (multi-mode) fiber optic cables are used to connect the servers,
Fibre Channel storage hubs and FC-AL switches, and RA4000/4100s in a
Fibre Channel Arbitrated Loop configuration.
Architecture of the Compaq ProLiant Clusters HA/F100 and HA/F200 1-13
Cluster Interconnect
Two types of cluster interconnect cables may be used depending on the type of
devices used to implement the interconnect, and whether the interconnect is
dedicated or shared:
■ Ethernet
If Ethernet NICs are used to implement the interconnect, there are three
options:
Dedicated Interconnect Using an Ethernet Crossover Cable:
An Ethernet crossover cable (supplied in both the HA/F100 and
HA/F200 kits) can be used to connect the NICs directly together to
create a dedicated interconnect.
Dedicated Interconnect Using Standard Ethernet Cables and a
private Ethernet Hub: Standard Ethernet cables can be used to
connect the NICs together through a private Ethernet hub to create
another type of dedicated interconnect. Note that an Ethernet
crossover cable should not be used when using an Ethernet hub
because the hub performs the crossover function.
Shared Interconnect Using Standard Ethernet Cables and a
Public Hub: Standard Ethernet cables may also be used to connect
the NICs to a public network to create a nondedicated interconnect.
■ ServerNet
If Compaq ServerNet adapters are used to implement the interconnect,
special ServerNet cables must be used.
Network Interconnect
Standard Ethernet cables are used to provide this type of connection.

Microsoft Software
Microsoft Windows NT Server 4.0/Enterprise Edition (Windows NTS/E) and
Microsoft Windows 2000 Advanced Server are the operating systems for the
Compaq ProLiant Clusters HA/F100 and HA/F200. The Microsoft clustering
software, Cluster Server for Windows NTS/E and Microsoft Cluster Service
for Windows 2000 Advanced Server (MSCS), provides the underlying
technology to:
■ Send and receive heartbeat signals between the cluster nodes.
■ Monitor the state of each cluster node.
■ Initiate failover and failback events.
NOTE: MSCS will only run with Windows NTS/E. Previous versions of Windows NT are not
supported.
NOTE: The HA/F200 only supports MSCS with Windows 2000 Advanced Server. Other
versions of Windows 2000 are not supported.
Microsoft Cluster Administrator, another component of Windows NTS/E and
Windows 2000 Advanced Server, allows you to do the following:
■ Define and modify cluster groups
■ Manually control the cluster
■ View the current state of the cluster
NOTE: Microsoft Windows NTS/E or Microsoft Windows 2000 Advanced Server must be
purchased separately for your Compaq ProLiant Cluster, through your Microsoft reseller.

Compaq Redundancy Manager (Fibre Channel)
Compaq Redundancy Manager, a software component that works in
conjunction with the Windows NTS/E operating system and the Windows NT
file system (NTFS), increases the availability of both single-server and
clustered systems that use the Compaq StorageWorks RAID Array 4000 and
RAID Array 4100 Storage System and Compaq ProLiant servers. Redundancy
Manager can detect failures in the host bus adapter, array controller or other
Fibre Channel Arbitrated Loop components. When such a failure occurs, I/O
processing is rerouted through a redundant path, allowing applications to
continue processing. This rerouting is transparent to NTFS. Therefore, in an
HA/F200 configuration, it is not necessary for MSCS to fail resources over to
the other node. Redundancy Manager, in combination with redundant
hardware components, is the basis for the enhanced high availability features
of the HA/F200 running Windows NTS/E.
The Compaq Redundancy Manager (Fibre Channel) CD is included in the
Compaq ProLiant Cluster HA/F200 kit. Redundancy Manager is licensed on a
single server or single cluster of servers basis. For more information about
installing Redundancy Manager in a Compaq ProLiant Cluster HA/F200, see
Chapter 3 of this guide. For detailed information about the Redundancy
Manager software, refer to the Redundancy Manager documentation included
