DR project

[Ron Irving]

Dear Guru's,

Ok. Here's the scenario. Currently, we have our production server, an rp8420 with 2 cells, 6 dual core cpu's, and 16GB of memory, attached to a Clarion SAN.

We are purchasing a new server for production, an upgrade version of what we have: 3 cells, 12 dual core cpu's, and 24GB of RAM.

I am planning to use the old production server for our DR setup, (once we have one.)

We will not being using MC Service Guard, but relying on ignite, (there will be some latency, I know, but it is what it is.)

Can anyone think of anything else that would be adventageous to use? Is there a cost-effective Openview solution out there?

If I can provide more informatin, I will.

Thanks in advance,

Ron

Shalom,

If you had the band width and money you could use a data line and data replication to keep your DR site up to date without Service Guard.

So long as you can afford to keep your DR site running, your current plan is a good one.

Keeping data backup tapes at the DR site will enable you to recover quickly if you don't use a solution that involves hot online backup of your application data.

Informix has a feature called Online Data Replication that will echo the transactions that happen on your production DB to another, duplicate DB. I would expect that Oracle must have something similar. Other, non-DB files could be set up with rsync and you would have a poor man's DR solution.

We use Ignite tapes to rebuild our boxes for DR.

Here is one thing. Remember to restore the server that runs your backups so you can use those tapes. We use Data Protector and realized it's also important to make sure we can have the most current version of the DP database. For DP, maybe you have it covered in a backup (check for this) or it can be as simple as a tarfile of /etc/opt/omni and /var/opt/omni. You can put that off to tape daily and send with your tapes for that day, or if you have access to DR site you could ftp it to a small box there.

All depends on your backup software. Point being you want to be able to restore as much and as quickly as you can.

Just a thought,
Rita
