https://community.hpe.com/t5/msa-storage/xp10000-performance-problems/m-p/831146#M3379 Hi,<BR /> <BR /> we want to migrate our main database from XP128 SANs to XP10000. Our developers has written a test pl/sql script, which tests a tablespace which resides on only one RAID Group (4 HDDs, Raid 5 3D+1P). On XP128, I need about 44sec, on XP10000 I need 53sec, which means, the new XP10000 is about 15% slower.<BR /> <BR /> What are we doing wrong, why is XP10000 slower than XP128.<BR /> <BR /> Both tests are made with no clients connected except the test machine.<BR /> <BR /> Another mystery is that testtool says a striped lvol residing on two raidgroups has the same throughput than a lvol residing on only one Raidgroup (raw devices measured).<BR /> <BR /> Can anybody please help me ?<BR /> <BR /> Thanks<BR /> <BR /> bk-ffm.de Wed, 22 Aug 2007 04:02:14 GMT ICF 2007-08-22T04:02:14Z https://community.hpe.com/t5/msa-storage/xp10000-performance-problems/m-p/831146#M3379 Hi,<BR /> <BR /> we want to migrate our main database from XP128 SANs to XP10000.
