HP HyperFabric manual Application Availability, Features

NOTE

Planning the Fabric

TCP / IP

TCP / IP

TCP/IP is supported on all HF1 (copper) and HF2 (fibre) hardware. Although some of the HyperFabric adapter cards support both HMP and TCP/IP applications, our focus in this section will be on TCP/IP HyperFabric applications.

Application Availability

All applications that use the TCP/IP stack are supported, including Oracle 9i and HP-MPI.

There are distinct differences between the feature set that is supported for TCP/IP and the feature set that is supported for HMP. Although TCP/IP and HMP applications are able to run simultaneously on the same HyperFabric cluster, for practical purposes, a HyperFabric cluster must run TCP/IP applications exclusively or HMP applications exclusively.

Features

•OnLine Addition and Replacement (OLAR): Supported

The OLAR feature allows the replacement or addition of HyperFabric adapter cards while the system (node) is running. HyperFabric supports this functionality on the rp54xx (L-class), rp74xx (N-class), rp8400 and Superdome systems, running on the HP-UX 11i platform with patch PHNE_25485.

For more detailed information on OLAR, including instructions for implementing this feature, see “Online Addition and Replacement—HP-UX 11i Only” on page 55 in this manual, as well as Configuring HP-UX for Peripherals Part Number B2355-90698 November 2000 Edition.

•Event Monitoring Service (EMS): Supported

Starting with the December 2000 releases B.11.00.11 and B.11.11.01, the HyperFabric EMS monitor allows the system administrator to separately monitor each HyperFabric adapter on every node in the fabric, in addition to monitoring the entire HyperFabric subsystem. The monitor can inform the user if the resource being monitored is UP or DOWN. The administrator defines the condition to trigger a notification (usually a change in interface status). Notification can be accomplished with a SNMP trap or by logging into the syslog file with a choice of severity, or by email to a user defined email address.

For more detailed information on EMS, including instructions for implementing this feature, see “Configuring the HyperFabric EMS Monitor” on page 97 in this manual, as well as the EMS Hardware Monitors User’s Guide Part Number B6191-90028 September 2001 Edition.

•MC ServiceGuard: Supported

Within a cluster, MC/ServiceGuard groups application services (individual HP-UX processes) into packages. In the event of a single service failure (node, network, or other resource), EMS provides notification and MC/ServiceGuard transfers control of
