HPs Project Odyssey
no, its not about .
2001: A Space Odyssey
2010 the next Space Odyssey
Odyssey so what is it all about?
It is not about the hardware It is not about Linux It is not about Serviceguard It is not about technology XYZ
Odyssey will provide you a fully integrated and supported operating environment with everything you need underneath your Mission-Critical applications Thats why we also call it the Mission-Critical Experience
Bringing the best of HP mission-critical to x86
Project Odyssey a journey embracing HP-UX, OpenVMS, Non-Stop and x86
Serviceguard High Availability

Serviceguard for Linux
* Based on internal HP testing
Linux environments for M-C Apps before Odyssey
The pieces are all there
... But you have to combine / integrate them yourself ... And you have to support the combination yourself ... And if any one of the components changes, youll do it all over again
And they change often in Linux world!
What makes a really good clustering software?
Reliable, robust failover mechanism
The cluster software must be able to reliably detect all kinds of failures Always predictably failover workloads without compromising data integrity
Simple to configure and use
Sophisticated automation to reduce manual errors Clustering software should be transparent to applications Fewer components especially intrusive kernel components
Minimal planned downtime
Must be upgradeable with minimum or no downtime Allow upgrading the OS and application without much downtime All re-configurations must be doable online
Mission Criticality
Proven time tested architecture no architectural changes every release Responsive and agile product support with experience in supporting mission-critical customers

Serviceguard common source code for UX and LX
One core product for two OS platforms
# Common code main(int argc,char* argv) { #ifdef LINUX do_linux_specific_code(); #endif
Same source code
Many features are identical or similar across Linux and HP-UX Platform-specific differences are accounted for by if-defs Equivalent test frameworks, quality criteria, design criteria
# more common code }
HP-UX Linux
OS features and differences impact Serviceguard implementations
The land of HP-UX
Developed and owned by HP Full control over feature set
The land of Linux
Open Source Operating System Various distros exist differ slightly from one another Enhancements / features controlled by Open Source and implemented by individual Linux Distros HP can propose/provide new features to Open Source HP might give up intellectual property HP has no control over acceptance of proposal
Support scope growing over time:
Certain Operating System features:
Only exist on one of the two OS platforms
Servers and storage
SG/HP-UX 16 nodes SG/LX 4 nodes (Proposed :16, 32 nodes) Application integration
Are implemented differently on HP-UX or Linux and some differences exist between the Linux distributions

Serviceguard Linux
Virtual Linux guests on VMware Serviceguard is certified on VMware ESX guests, not on ESX hosts, and provides high availability for applications, not for the virtual machines themselves
Cluster configuration options A Serviceguard cluster that includes virtual machine nodes can consist of: Virtual machines on separate hosts Virtual machine and physical nodes All of the above Virtual machines on the same host cluster in a box (not recommended)
Serviceguard Linux
Virtual Linux machines on VMware Install VMware tools Use NIC teaming on ESX host level, enable beacon monitoring Use Raw Device Mapping (RDM) Install SCSI persistent reservation (sg_persist) Install the appropriate vmtoolkit rpm for vminfo
The combination of VMware HA and Serviceguard for Linux running in guests is not supported vMotion is not supported on Serviceguard cluster nodes Extract from technical white paper (4AA4-2016ENW, June 2012) Using HP Serviceguard for Linux with VMware virtual machines

Pricing details and example
Serviceguard for Linux best implemented by TS experts
TS offers three services to address Serviceguard for Linux implementation
SG LX Installation & Startup Service Scope limited to installation & configuration HA design & planning and project management must be provided by the customer SG LX Implementation Packaged Service Core service with enhancement options based on toolkit and number of application packages This is similar to what we offer for HP-UX SG LX SOW based implementation Completely custom SOW that gets defined by SA and customer Used for multi cluster implementations or special requirements
With the new I&S service, TS provides an installation service that addresses the competitive nature of the Linux HA market The suite of implementation services allows you to address customers of all sizes and complexities
