Specifications

Storage and Adapter Options
reside on a disk array subsystem (Redundant Array of Inexpensive Disks, or RAID). LifeKeeper
supports a number of hardware RAID peripherals for use in LifeKeeper configurations. See Storage
and Adapter Options for a list of the supported peripherals.
Consider the following issues when planning the configuration of your storage devices:
l LifeKeeper manages resources at the physical disk or Logical Unit (LUN) level, making the
resources on each physical disk or LUN available to only one server in the configuration at a
time. As a result, it is a good idea to plan disk allocations before you begin to configure
LifeKeeper. For example, each hierarchy in active/active configurations must access its own
unique LUN, so a minimum of two LUNs is required for a two-node active/active configuration.
l Some model-specific issues and hardware configuration details are maintained at Storage and
Adapter Configuration.
Adapters - Based upon the type of configuration and the number of peripherals, determine the types
and number of SCSI or Fibre Channel Host Adapters required. It is important that any adapter you
choose be supported by LifeKeeper, as well as by your Linux distribution so that there is a driver
available. Refer to Supported Adapter Models for a list of supported host adapters. For reference
purposes, you should add the host adapter specifications to your configuration map.
Storage and Adapter Options
The following tables list the disk array storage models and adapters currently supported by
LifeKeeper in shared storage configurations. For each storage or adapter model, the type of
certification is indicated. If storage vendors support other adapter models related to those listed in
Storage Adapter Models, then LifeKeeper for Linux supports those adapter models too. Refer to
Storage and Adapter Configuration for details about driver versions and other configuration
requirements for these arrays and adapters.
Note that a supported disk array and adapter are not required in LifeKeeper configurations involving
non-shared storage with IP failover only or when using SteelEye Data Replication or Network
Attached Storage.
