Mac Xserve RAID usage

Dear experts,

I inherited a Mac Xserve RAID from our previous sysad. He wasn't familiar with it so it kind of sat in its box in our server room for 2 years (I have no idea why they bought it in the first place). Anyway, this is the first time I've seen one so I have no idea what it's for.

I mean, I know that the RAID array can help ensure data will not be lost and there's a truckload of data I can put in there (it has a capacity of 7TB), but that's as far as I know.

For now, I've managed to figure out how to hook it up to another Mac Xserve G5 and initialize the arrays. Now that I've got terabytes of storage space, I don't know if this should be a database server, a web server, an FTP server or something else. We've got plenty of the three aforementioned servers, so I'm hoping to use this for something else.

BTW, the Mac Xserve G5 is running on Mac OS X 10.4 (it sat in the server room for 2 years also).

Thanks in advance!

You dont have to attach the xserve RAID to a mac. You can attach this to any fibre channel card on a variety of different servers. You can also split the LUNs, so have one side attached to one server, and another side attached to another server.

Thanks for the reply. It's no longer attached now to the Mac. I just used the Mac to initialize the arrays using RAID Admin. The question I'm asking myself now is "what do I do with this afterwards?"

Is it fine to just use this for network storage or is this type of hardware usually used for something else (serving streaming media, FTP server, etc.)?

There are many different possibilities and benefits of RAID other than a large data store.

Generally I would recommend finding out what you want to store so you can set up the RAID levels on the RAID appropriately. For instance:

If you wanted a large data store, with redundancy: Then you might select RAID 5. This would be beneficial for a large data store of files that you wouldn't consider mission critical to business, but are still fairly important

If you wanted to store a medium amount of mission critical data: Then you might select RAID 1+5 (Nested mirrored RAID 5).

So it all really depends. Ask yourself the following questions:
* Do you have a large amount of data that you need to store? ( maybe Home folders, Mail)
* Do you have a need to store mission critical data?

Okay, I'll try to find some things to put in there. There's not a lot right now, we'll probably be using only about a tenth of the space. But thanks anyway.
