The company says that until now, small- to mid-size companies were faced with prohibitive costs to ensure the availability of their most critical data and applications. With the ability to monitor and recover the most popular applications on Linux such as Apache, Oracle 9i, sendmail, SAMBA, and MySQL, LifeKeeper for Linux with ProLiant DL380 Packaged Clusters is designed to provide failure-free reliability.
According to the company, SteelEye's LifeKeeper is the first solution to deliver Linux high availability on the ProLiant DL380 Packaged Cluster. LifeKeeper for Linux was first certified on the HP ProLiant CL380 Packaged Cluster in 2000 using the HP StorageWorks RAID Array 4000 for shared SCSI storage.
The changes made to the shared SCSI storage in HP ProLiant DL380 Packaged Clusters add independent paths to the newly announced SMART Array Cluster Storage subsystem. This dual path may eliminate the single path to shared storage, which was a potential point of failure in previous implementations.
Furthermore, storage controllers operate in active-standby mode. So if one controller has a problem, the SMART Array initiates a failover to the standby controller. All the while, LifeKeeper is designed to ensure that continuous access to applications and data is maintained. Coupled with the other built-in hardware redundancy components of the ProLiant DL380 (power supplies, fans, and buses), the dual- controller storage unit should provide protection against hardware failures.
