It's not a fair comparison in terms of hardware. We had a 2-yr old Netapp in need of upgrade, and replaced it with a new modern Sun. It was a definite upgrade in terms of hardware, so the two systems are not on equal ground in terms of performance comparison. I suppose I was being unfair when I emphasized the huge performance difference we saw, but I don't feel it was totally unfair. This is a more fair representation, albeit also more long-winded: Our old system had 1 Gb Ether. It was a NetApp Storevault S500 with 5 disks. You would expect this to be limited by the Ethernet, but at all times, its performance was significantly slower than we thought would be reasonable. We could never seem to get more than 300Mbit across that link, and could not find any way to identify why it was so slow. Since it's onTap, there is a lack of standard monitoring tools (iostat, top, etc) and the supposed "equivalent" didn't give us valuable information, despite all the tech support hours spent on phone and email. This was part of the influence that encouraged us to go with Sun: because we have a complete OS and could install anything we want, to look at everything we want to know. The Sun box is much more open to the curious admin. If you compare a modern NetApp versus a modern Sun Server, I cannot say which would perform better. I expect they would both be limited by the Ethernet, even if you aggregate all the links. But I expected the old Netapp to max out 1Gb, and was disappointed. I expect my new Sun to max out 4x 1Gb, and have not been disappointed. Our new server is a SunFire X4275, using ZFS striping mirrors, and one SSD for ZIL. It easily maxes out the 4x 1Gb ethers. _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
