I know we bough the 4 proc opteron unit with the sas jbod from dell and it has been extremely excellent in terms of performance. Was like 3 times faster the our old dell 4 proc which had xeon processors. The newer one has had a few issues (I am running redhat as4 since dell supports it. I have had one kernel failure (but it has been up for like a year). Other then that no issues a reboot fixed whatever caused the failure and I have not seen it happen again and its been a few months. I am definitely going dell for any other server needs their pricing is so competitive now and the machines I bought both the 1u 2 proc and the larger 4 proc have been very good.

As it happens I will have an opportunity to test the dual controller theory. In about a week we are picking up another md1000 and will attach it in an active/active configuration with various hardware/software RAID configurations, and run a battery of database centric tests. Results will follow. By the way, the recent dell severs I have seen are well built in my opinion...better and cheaper than comparable IBM servers. I've also tested the IBM exp3000, and the MD1000 is cheaper and comes standard with a second ESM. In my opinion, the Dell 1U 1950 is extremely well organized in terms of layout and cooling...dual power supplies, dual PCI-E (one low profile), plus a third custom slot for the optional perc 5/i which drives the backplane. merlin ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
