MetroCluster with SRDF and ATM network?

[Igor Streharski]

Hello all,

Does anyone know whether MetroCluster with SRDF over ATM network works?

[melvyn burnard]

I was under the impression SRDF goes via it's own proprietary links, not ATM.
If you are asking does MetroCluster/SRDF support ATM for networking, then yes it does with the normal MC/ServiceGuard constraints

Here's an EMC link to support:

It is not clear what exactly you mean.

1) Do you want to the EMC SRDF/ESCON connection over an ATM network cloud?

The SG lab is currently evaluating this possibility. So it is not supported (yet), but may work. Restrictions to distance are likely.

2) Do you want to use ATM as a normal lan for SG?

ATM lan's cannot be configured into SG (ie. no heartbeat traffic, no monitoring of lan's health by SG directly), as they do not support DLPI. But ATM can be used as a data lan external from SG, with HA features provided by an EMS monitor. Refer to http://docs.hp.com/hpux/onlinedocs/B1056-90004/00/00/26-con.html
