4 Configuring application servers
Overview
This chapter provides general connectivity information for all the supported operating systems.
Where applicable, an OS-specific section is included to provide more information.
Clustering
Clustering is connecting two or more computers together so that they behave like a single computer.
Clustering is used for parallel processing, load balancing, and fault tolerance.
See the Single Point of Connectivity Knowledge (SPOCK) website
for the clustering software supported on each operating system.
NOTE:
For OpenVMS, you must make the Console LUN ID and OS unit IDs unique throughout
the entire SAN, not just the controller subsystem.
Multipathing
Multipathing software provides a multiple-path environment for your operating system. See the
following website for more information:
See the Single Point of Connectivity Knowledge (SPOCK) website
for the multipathing software supported on each operating system.
Installing Fibre Channel adapters
For all operating systems, supported Fibre Channel adapters (FCAs) must be installed in the host
server in order to communicate with the EVA.
NOTE:
Traditionally, the adapter that connects the host server to the fabric is called a host bus
adapter (HBA). The server HBA used with the EVA4x00/6x00/8x00 is called a Fibre Channel
adapter (FCA). You might also see the adapter called a Fibre Channel host bus adapter (Fibre
Channel HBA) in other related documents.
Follow the hardware installation rules and conventions for your server type. The FCA is shipped
with its own documentation for installation. See that documentation for complete instructions. You
need the following items to begin:
•
FCA boards and the manufacturer’s installation instructions
•
Server hardware manual for instructions on installing adapters
•
Tools to service your server
The FCA board plugs into a compatible I/O slot (PCI, PCI-X, PCI-E) in the host system. For instructions
on plugging in boards, see the hardware manual.
You can download the latest FCA firmware from the following website:
Enter HBA in the Search Products box and then select your product. See the
Single Point of Connectivity Knowledge (SPOCK) website (
for supported FCAs by operating system.
