Project Odyssey and Serviceguard for Linux


Project Odyssey

Advance HP Integrity / HP-UX / OpenVMS / NonStop as mission-critical design center

HP is the only vendor unifying UNIX and x86 within a single platform

Revolutionize the mission-critical experience with a suite of products and services for choice and investment protection

Leading the market with a mission-critical experience across UNIX and x86 architectures.

7x 68x 54%

Greater SMP scalability * More reliable * More efficient *

* Based on internal HP testing


Project Odyssey brought back Serviceguard solutions for Linux in 2012

Serviceguard for Linux


Why do systems fail?

Human Error

Fatigue

Lack of knowledge or training

Distractions

Carelessness

Hardware failures

Fan failures

Memory failures

I/O card failures

Disk failures

Bad blocks on hard drives

Cable and I/O path failures

Platform maturity

OS crash, freeze

Patching (~2 months)

Driving for performance and scale

File systems go read-only

Running out of free RAM

Single-system RAS is key but not sufficient for your most mission-critical workloads
