Default Dell Technical Test - SANs

Hi Guys,

I have a technical test with Dell next Tuesday and I need the following information: SAN environments, RAID configurations, iSCSI-protocol and -initiators, and current MPIO-software and –policies?

What do I need to know about each topic as the test is 1 hour? Any advice would be greatly appreciated.

Niall

You are obviously not ready for the test you might want to reschedule for after you've learned more.

Those are pretty broad topics. You'll need to do a good bit of research on each of them before you take the test unless it's a very easy test.

RAID is a method of spanning data across multiple hard disks, and usually you also implement redundancy, so that if a drive fails, you can replace it without losing all of the data.

iSCSI is a method for using the SCSI protocol over an ethernet network. I believe SCSI is basically a parallel interface for attaching disk drives to a computer.

With iSCSI, the initiator is usually that computer that is connecting to the iSCSI host. The initiator mounts a remote hard drive (or raid array) over the ethernet network and treats it as if it were a hard drive directly plugged into the computer.

SAN means Storage Area Network. Start with the wikipedia page on SAN networks, it covers a lot of it. I'm not sure what you mean by 'environments' probably the common types of san infrastructure or SAN switches? unfortunately I don't know a whole lot about SANs.
