OnApp OpenE Active/Passive Failover SAN Hardware

[enealDC]

Thank you for the info guys.



What do you guys think about the choice of the raid card? How often it failed?

You are welcome...
I personally like the Areca controllers. I think OOB management for RAID controllers is a must have feature.
I've had major problems with the Adaptec Storage Manager not sending email based alerts because you have to have the GUI running constantly on a node. In addition, on the Areca controllers I can schedule bi-weekly checks of my RAID5 volumes.

I have several Areca controllers and haven't had one failure yet.

Here is the updated spec

The 10G port is going to be directly connected to the other SAN unit for replication purpose.

Looks good. One other piece of advice. I suggest you use something like DRBL or a live CD and run that to do some burn in/performance testing. Use iometer or your favorite tool and get all your benchmarks and performance numbers. This will give you a good idea of what you can reasonably expect when you install Open-E.

enealDC,

Thank you for the tips.

How about CentOS live CD and then use iometer?

It might not have the tool i need on CentOS for benchmarking.

So we test the I/O?

Find this KB, it's about performance testing for NIC and Volumes:

When setting up Active / Standby unit of open-e using volume replication over 10G local link (inter connect), is there any option on the Open-E for Virtual IP?

The VM would be connecting to the ISCI initiator on virtual IP

So i would expect only active open-e san broadcast the ARP but once failover, the peer unit would take over the IP address by broadcasting its mac address for it.

Anyone has experience on how Open-e works?

I have read up on open-e docs and it can do what i need

cant wait for the hardware to arrive

Yes, you can assign the VIP.

Correct.

So i would expect only active open-e san broadcast the ARP but once failover, the peer unit would take over the IP address by broadcasting its mac address for it.

Correct again, the passive node will take over all resources.

Anyone has experience on how Open-e works?

With over 25,000 installs, i would say YES!
