Hi all.
To start off, I am a member of Charles Capps forum, the Solareclipse network.[nbsp][nbsp]I've been lurking here for quite some time now, as it is a VERY interesting place.[nbsp][nbsp]I hope to perhaps someday set up an account with you guys.[nbsp][nbsp]Or perhaps work for ya.[nbsp][nbsp]Either will do just nicely. :)
I am however, taking a course on networking, and I was wondering if it was okay to ask TeRRa some questions, *waves to TeRRa* Hi, can you see me?
We've just started doing stuff on Fault Tolerance.[nbsp][nbsp]I've seen TeRRa mumble on about Mirror sets and arrays (partition x got kicked out of the mirror array and I have to rebuild them... yadda yadda yadda).[nbsp][nbsp]Now I've learned that Mirror sets mirror the root hard drive so in case of failure of the primary partition, the secondary takes over.[nbsp][nbsp]The same applies to vice versa.
We've also learned about Stripe Sets with Parity (SSPs), where a stripe set is when data is spread over a set of 3 or more partitions and a parity set is used in the event of partition failure to reconstruct data.
Questions:
1) It appears that Mirror sets appear to be the better form of Fault Tolerance IMHO.[nbsp][nbsp]But why is Mirror Sets classified as RAID level 1 while Stripe Sets with Parity labelled as RAID level 5?
2) How is it possible to regenerate data in a SSP?[nbsp][nbsp]And why is it so much better than using Mirror Sets?
3) What kind of Fault Tolerance does FQ use?[nbsp][nbsp]How many mirrors do each Server have?[nbsp][nbsp]Do each server contain a Stripe set as well?[nbsp][nbsp]How many disks are used in these Stripe sets.
4) How big are the HDs in each server?
More questions to come.[nbsp][nbsp]Thanks to whomever could reply!!! :)
