RE: RAID5+

And the date of the paper. Excuse my ignorance: I know what RAID 5 is, but what is 5+ ? -----Original Message----- From: Anjo Kolk [mailto:[EMAIL PROTECTED]] Sent: Monday, October 28, 2002 4:59 PM To: Multiple recipients of list ORACLE-L Subject: RE: RAID5+ What would interest me is the number of disks used in each test.   Anjo.   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Brooks, Russ Sent: Monday, October 28, 2002 11:24 PM To: Multiple recipients of list ORACLE-L Subject: RAID5+   Hi,   I just got forwarded a whitepaper from Hitachi and Oracle, that compairs raid 5+ and raid 1 using the TPC-C benchmark test suite.  The claim is that raid 5 is as fast or faster.  While I'm waiting for a comparison or raid 5+ with raid 0+1, I thought I'd take a poll with the list.  The benchmark is using the Hitachi 7700E.   Has anyone heard other recommendations attributed to Oracle that are pushing raid 5+ as the configuraton for "unrivaled performance"?  Has new disk technology changed the general conception that raid 0 or 0+1 provides better performance than other raid levels?   Thanks, Russ
