Compaq ProLiant Servers
Compaq industry standard servers ar e a primary component of all models of
Compaq ProLia nt 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 Com paq 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
Cluster Certification Test Suite on numerous occasions. In fact, Compaq was
the first vendor to be certified using a shared storage subsystem connecte d 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.
Compaq StorageWorks RAID Array 4000 Storage System
Microsoft Cluster Server (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 RAID Array 4000 storage system is the shared
storage system for the Compaq ProLiant Clusters HA/F100 and HA/F200. The
storage system consists of the following components and options:

Compaq StorageWorks RAID Array 4000
The Compaq St orageWorks RAID Array 4000 (RA4000, previously Compaq
Fibre Channel Storage System) is the storage cabinet that contains the disk
drives, power supply, and array co ntroller. The RA4000 can hold twelve
1-inch or eight 1.6-inch Wide-Ultr a SCSI drives. The RA4000 supports the
same hot-pluggable drives as Compaq Servers and Compaq ProLiant Storage
Systems, online capacity expansio n, online spares, and RAID fault tolerance
of SMART-2 Arr ay Controller technology. The RA4000 also supports
hot-pluggable , redundant power supplies and fans, hot-pluggable hard drives,
and MSCS.
The HA/F100 and HA/F200 ProLiant Clusters must have at least one RA4000
set up as external shared storage. Consult the Order and Confi gur ati on G ui de

Compaq StorageWorks Fibre Channel Storage Hubs
The servers in a Compaq ProLiant Cluster HA/F100 and HA/F200 are
connected to one or more Compaq StorageWorks Raid Array 4000 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. The Compaq StorageWorks Fibre Channel Storage Hub is a
critical component of the FC-AL configuration and allows up to five RA4000s
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 hubs are used. Either the
7-port or 12-port hub may be use d in both types of c lusters. For the H A/F200
cluster, 7-port and 12-port hubs may be combined, if desired. If the maximum
number of supported RA4000s ( 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 RA4000s. Other
FC-AL capable devices such as tape backup systems should not be connected
to these unused ports under any circumstances.
Compaq StorageWorks RA4000 Controller
The Compaq Stor ageWorks RA4000 Controller is fully RAID capable and
manages all of t he drives in the RA4000 storage array. Each RA4000 is
shipped with one controller installed. In an HA/F100 cluster, each array
controller is connected to both servers through a single Fibre Channel storage
hub. In an 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. This dual-connection configur ation
implements a vital aspect of the enhanced high availability features of the
HA/F200 cluster.

Compaq StorageWorks Fibre Channel Host Adapter
Compaq StorageWorks Fibre Channe l Host Adapters (host bus adapters) are
the interface between the server and the RA4000 storage system. At least two
host bus adapters (PCI or EISA), one for each cluster node, are required in the
Compaq ProLiant Cluster HA/F100. At least four host bus adapters
(PCI only), two for each cluster node, are required in the HA/F200
configuration.
For more information about this product, refer to the Comp aq St or a geW ork s
Fibre Channel Host Adapter 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 and host bus adapter.
GBIC-SW module s hot-plug into Fibre Channel storage hubs, array
controllers, and host bus adapters. These converters provide ease of expansion
and 100 MB/s performanc e. GBIC- S W modu les s upp ort distances up to
500 meters using multi-mode fibre optic cable.
Cables
Three general c ategories 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,
hubs and RA4000s in a Fibre Channel Arbitrated Loop configuration.

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
1.
If Ethernet NICs are used to implement the interconnect, there are three
options:
Dedicated Interconnect Using an Et hernet 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 E t hernet
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: Standa rd Ethernet cables may also be used to connect
the NICs to a public network to create a nondedicated interconnect.
ServerNet
2.
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.
1-12 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide
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 re source 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 c onnect to virtual
servers, which ar e cluster groups that contain their ow n IP addresses.
Within this guide , communication be tween the network clients and the cluster
is termed cluster-to-LAN communication.
Private or Public Interconnect
There are two types of interconnect pa ths:
■ A private interconnect (also known as a dedicated interconnec t ) is used
solely for intracluster (node-to-n ode) communicatio n. Communication
to and from network clients does not occur over this type of
interconnect.
■ A public interconnect not only takes care of c ommunication betw een the
cluster nodes, it also shares the data path with communication between
the cluster and its network clien ts.
Architecture of the Compaq ProLiant Clusters HA/F100 and HA/F200 1-13
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 c ommunication can continue if the primary path is disrupted.
Compaq recommends configuring the client LAN as a bac kup 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 A dministrator.
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).

works in conjunction with the Windows NT file system (NT FS), increases the
availability of both single-server and clustered systems that use the Compa q
StorageWorks RAID Array 4000 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 the
Windows NT file system. Therefore, in an HA/F200 configuration, it is not
necessary for MSCS to fail resources over to the other node. Redundancy
Manager, in c ombination with r edundant hardware components, is the basis
for the enhanced high availability fe atures of the HA/F200.
Compaq Redundancy Manager (Fibre Channel) CD is included in the Compaq
ProLiant Cluster HA/F200 kit.
Compaq Cluster Verification Utility
The Compaq Cluster Verification Utility (CCV U) is a software utility that can
