EVA & XP1024

hi,
I have one EVA6000 and a XP1024. when i copy a 44GB file from EVA to EVA costs 7 minutes while copy from XP1024 to XP1024 will cost 17 minutes. and i read a big file 50G from EVA, it cost 10 minutes, and read a file 50G from XP1024 will spend 20 minute.
and i ask someguy who test on the XP1024&Xp12000, copy a 47GB file on XP1024 will cost 28 minutes, 18 minutes on XP1200.
So my question is: if the read a file I wonder if a single large file reading performance on EVA is Good than on XP platform and why? and If above is True, is there is any setting for the large sequential read request on XP1024?

Re: EVA & XP1024

Hi,

You've told us about the storage systems, but nothing about the disk configurations, or any details about the connected hosts.

There could be many different factors that could affect the performance of different disk systems...

Cheers,

Rob

EVA6000 has 36 * 300 10k disk.
XP1024 has 11 * 146GB 15K disk group. and 24GB cache.
hpux is 11.23.
we do the test on the same server which JFS is 4.1.

Re: EVA & XP1024

EVA disk group has 3 times more disks than the XP1024, so it can transfer 3 times more data por second. Until you start talking about disk groups with 50 or more disks, the internal cabling or the controllers are not the limit.
