Memory requirements
The memory requirement for Serviceguard for Linux depends on the number of packages configured in the cluster. The
following equation provides a rough estimate of how much lockable memory is needed:
Total memory = 6 MB 80 KB/package in cluster
The total amount is needed on all nodes in the cluster, regardless of whether a given package or resource is on that node or
not.
Application toolkits
Available for download at no additional charge are application toolkits for Apache, NFS, MySQL, Samba and SendMail,
which are a separate set of shell scripts, and a binary file that allows you to configure Serviceguard packages that mount
highly available networked file systems. Additional for fee toolkit is available for Oracle. You can modify the shell scripts for
your specific environment. You cannot use Serviceguard toolkits without the associated applications. The application must be
installed on your Linux system before you install, configure, and test your package.

Quorum service
requirements
The Quorum Service provides cluster locking and must be installed and run on a system outside the cluster. The Quorum
Service is a separate product provided on the "Serviceguard Distributed Components" CD. The node on which the Quorum
Service is running must have network connectivity to the clusters for which it is providing services. Ensure that the connection
with each node is independent of the cluster heartbeat connection so that both are not likely to fail at the same time. The
Quorum Service is required for a 2-node configuration and recommended for a 3- to 4-node configuration. The Quorum
Service in a Linux environment can manage up to 50 clusters and 100 nodes. The Quorum Service and clustered nodes may
be on different subnets.

HP Serviceguard for Linux supports redundant networks, even though these are not shown in the diagrams. The redundant
client network connections allow local failover from one NIC to another in case of failure in the network path. These
connections must be on the same subnet. This is implemented using Channel Bonding. Failover from one NIC to another
prevents a package, or the entire system, from failing over to another system. This minimizes impact to the application and
to the users.

SCSI configuration
topology
Use the ProLiant configuration tools to find the appropriate part numbers.
A hub is necessary to connect the two client LANs. The customer must then connect the client LANs to the remainder of their
network infrastructure.
What is critical is the number of LAN connections and the SCSI connection to the Smart Array-Cluster Storage. There needs
to be a minimum of 2 LAN connections per server configured in a bond and used for both heartbeat and data, whereas the
recommended configuration includes 3 LAN connections per server (1 heartbeat and 2 public) with bonding and 1 SCSI
adapter connection to the Smart Array-Cluster Storage. Integrated LANs may be used when possible.
This is HP's recommended cluster configuration for SCSI with a redundant network for data.
SCSI configuration
topology
· Up to 16 nodes are supported in a fibre channel configuration
· A quorum service is only required for two node configurations, it is optional for three to eight node configurations.
· LAN connection to switches white papers are available on the Procurve section of the HP Web site
(http://www.hp.com/rnd/index.htm), describing how to set up the LAN environment for the best availability.
· The key items that need to be in the servers are the correct number and type of LAN connections and the Fibre Channel
host bus adapters (HBAs). Various supported Fibre Channel HBAs are used in this example.
NOTE: The Fibre Channel HBAs are not available directly from HP. These must ordered from the reseller.

Disaster-tolerant solution
for Linux
HP's metropolitan cluster for Linux is an integrated solution, utilizing HP Serviceguard for Linux and the Cluster
Extension XP software (CLX) for the HP XP disk arrays, product number B9534A.
CLX is host-based software that integrates Continuous Access (CA) XP remote mirroring with Serviceguard
failover/failback operations.
Integrating CLX with Serviceguard for Linux allows application packages to automatically fail-over:
Among local nodes that are attached to the same XP series array.
Between one system that is attached locally to its XP frame and another remote node that is attached
locally to another XP frame.

Cluster topology and
geography with Cluster
Extension XP
The current maximum number of nodes supported is eight. A Quorum Service node is required to provide arbitration
to clusters in a CLX configuration. It provides arbitration services for the cluster when a cluster partition is discovered.
A node running the Quorum Service cannot be a member of any cluster to which it is providing cluster quorum
services.
The recommended configuration implements two data centers with the nodes of the cluster split equally between
them and a third site housing the Quorum Service.
The minimum supported configuration is two data centers, with one of the data centers housing the Quorum Service.
In this configuration, if the data center housing the Quorum Service is down, the nodes in the second data center will
not be able to form the cluster, as there is no quorum. At the minimum, the Quorum Service should be in a separate
room with its own power circuit.
The maximum distance between the data centers is currently limited either by the maximum distance supported for
the networking type or by the CA link being used, whichever is shorter-but no more than 100 kilometers.
DWDM (Dense Wave Division Multiplexing) device can be used for the network and data replication links to
increase the distance up to 100 kilometers between data centers.
Cluster networking links
with Cluster Extension XP
The supported network interfaces used for cluster heartbeat are 10Base-T and 100Base-T.
There must be less than 200 milliseconds of latency in the cluster heartbeat network between the data centers.
No routing is allowed for the cluster heartbeat network between the data centers.
There must be at least two alternately routed cluster heartbeat links between the data centers to prevent the
"backhoe problem". The "backhoe problem" can occur when all cables are routed through a single trench and a
tractor on a construction job severs all cables, disabling all communications between the data centers.
One of the heartbeat links has to be a dedicated link. The other heartbeat link can be shared with the application
network link.
Data replication
continuous access (CA)
links
There must be at least two alternately routed CA links between the two primary data centers.
NOTE: The maximum distance between the two primary data centers is currently limited either by the maximum distance
supported for the cluster networking type or by the CA link being used, whichever is shorter.
DWDM links for both
networking (cluster
heartbeat and application
network) and CA
The maximum distance supported between the data centers for a DWDM configuration is 100 kilometers.
Both the networking (cluster heartbeat and application network) and CA links can go through the same DWDM box.
A separate DWDM box is not required.
The fiber-optic links between the DWDM boxes must be "dark fiber" links, non-switched circuits. There must be two
alternately routed links between the two primary data centers.
For the highest availability, it is recommended to have two separate DWDM boxes (in each data center) used for
the links between each data center. However, since most DWDM boxes are typically designed to be fault tolerant,
it is acceptable to use only one DWDM box (in each data center) for the links between each data center. If a single
DWDM box is used, a minimum of one active and one redundant standby fiber link feature of the DWDM box must
be configured. When using ESCON for CA, note that the ESCON timeout is shorter than the DWDM link failover
time. Therefore, a minimum of two active fiber links on the DWDM box must be configured.
Quorum service
With only one IP address configurable for a Quorum Service, it is suggested to configure the LAN used for the
Quorum Service IP address with two or more physical LAN cards using Channel Bonding to improve the availability of
the Quorum Service if a LAN card failure occurs. A node running the Quorum Service cannot be a member of any
cluster to which it is providing cluster quorum services.
The Quorum Service can provide arbitration services for up to 50 heteregenous clusters or 100 cluster nodes.
Recommended configuration with two data centers and the Quorum Server in a third location.

HP Serviceguard for Linux ProLiant Cluster
Specifications
In the example above, the DWDM boxes connected between the two Primary Data Centers are configured with multiple
dark fibre links. The DWDM links are used for both networking and CA data replication. If the DWDM box is fault tolerant,
only one is required in each data center. If it's not fault tolerant, two are required in each data center. The Quorum Service
site distance can be up to 100 kilometers away from either Primary Data Center since DWDM links are also used. The
Quorum service can be on a different subnet than the cluster. It is also supported to connect to the Arbitrator data center
without DWDM links, as long as the distance is within the allowed specifications for the network type being used.
