maximum distances between cluster nodes

[Stefan John]

Hi,

Is there anywhere any information about max distances between cluster nodes by using Serviceguard Basic, Metrocluster or Continental Cluster. And what is Extended Distance Cluster - just a configuration or a separate product?

Thanks in advance ;-)

Hi Stefan,


It is just a configuration and solutioning. I attached HP Serviceguard portfolio and it explains also the maximun distance of cluster nodes for your review.


WK.

p/s: please assign point.

Thank's a lot. Just one more question: every MC/SG solution (EDC, Metro, Continental) based on standard SG software components?! There are no specific extensions/modifications in ServiceGuard - regarding network latency or something else like that?

There is no separate product for all type of clusters, difference is in cluster design.

This is product page - http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=T1905BA

This whitepaper "Understanding and Designing Serviceguard Disaster Tolerant Architectures, 1st Edition, December 2006" should explain the differences, etc. Here's the URL http://docs.hp.com/en/B7660-90018/index.html and a link to the pdf version is on the left hand side of that page.
