70-282 / Raid-5

Hi,

I'm preparing for the 70-282 MCP to become an SBS. I'm a bit confused by a
couple of terms I see in my practice questions and hope I can get a
clarification from the community. Thanks in advance!

Please help me understand the difference between a hardware raid 5 and a
software raid 5

Thanks!

Hardware RAID (any number) is handled by a physical, hardware controller
(RAID controller). Software RAID is handled by, yes you guessed it,
software. Windows Server for example has software RAID options.

Would you still not have to have at least 3 disks (in addition to the system
disk) to implement a Raid 5 either HW or SW? With that said, would you still
need some sort of controller to connect the 3 disks needed to implement a SW
Raid?

My confusion is, how do you implement a SW Raid 5?

thanks

I hunted around for a good link explaining this, but didn't really find one
that I liked. This is the best I could find:
http://en.wikipedia.org/wiki/RAID#RAID_implementations. Please look at this
and then ask any specific questions that are left. I think this will help
you. There are more detailed links but they are often OS/vendor specific.

Hi Scrotch,

Yes in order to configure a RAID-5 array, whether by software or hardware,
you would need to have three (or more) phsycial drives. That holds true for
any RAID configuration. The differences are:
1. For a hardware RAID you obviously need a RAID controller instead of the
regular SCSI/SATA/IDE controller; and
2. hardware RAID is OS agnostic. Though you will need a driver for it, your
hardware RAID should work in any OS.

Good luck on 70-282 and let me know how you do!

I was using "Self Test" software to prepare for the exam, took it last night.
many questions felt very familiar, thought I was doing well. On the
practice tests, I was getting 96% and 98% consistantly. Meaning out of 50
questions, i'd miss 1 or 2. I finished the test, thinking I did great, and
scored 612. 700 is the passing score. I really thought I was prepared. I'm
now going to try the "Measure Up" practice tests. I'll use them both now.
