Poll: High Avalability - which technology are you using

[Former Member]

Hi folks

I'd like to start a small poll on high availability here. I am wondering how you guys are running your HA systems.

Are you using a VM environment (Vmware, XEN, KVM)? Or a failover cluster solution, like RHCS or veritas cluster? Or a database based solution, like for example Oracle RAC? Or a combination of them?

What kind of SAP system are your running? What is your personal opinion, what are your experiences?

We are running our HA systems on HP-UX with Service Guard (active/passive failover cluster with storage/os based replication). Most SAP systems are medium to large ERP 6.0 and a few PI systems. On linux we only have a few systems with a manual failover solution.

I intentionally posted this in the linux forum, but other platform solutions are welcome as well.

Best regards, Michael

Hi Micheal,

We are also using HPUX and SGeSAP, all our production systems ECC, PI, EP and CRM are running on HA.

For BI we are running on Windows 2003 MSCS.

So far so good on HPUX part, we had few issues in MSCS like sudden failover of resources.

Hi,

we are running our productive system under AIX HACMP Cluster.

Worked with HPUX Serviceguard on my last Job, think thats more easy to administrate

Additionally we are running the DB2 Database also in primary and secondary database mode. So the secondary database gets an automatic logshipping all the time.

kind regards

I mark this as answered, but everyone is still invited to give their views on HA on linux.

Thank you guys!

Hi Michael,

We are using VCS in red hat linux.

The setup is like this one san disk is shared between two hosts.So whenever one host fails other one switches over.

Hello Michael,

on HP-UX we are using Serviceguard, of course. On Linux we had also some Serviceguard instances, now we are evaluating SLES HA extensions to mimicry Serviceguard. The difficult part of SLES HA is a dual data center setup. Oracle RAC/ASM isn't really an option when Oracle is pushing one more and more to OEL.

HP Virtual Connect would be an option to manually mimicry HA solutions or if you don't want to use VMware.

Regards,

Mark
