N-Class Vs V-Class

[Stephen Young_1]

Hi,

I am currently importing an Oracle database on a V-Class as so far it has taken 3.5 hours.
I carried out the exact same import yesterday on an N-Class and it completed in 1.75 hours.
Both imports are onto internal disk, all oracle parameters are identical.
Can anyone shed any light on why my N-Class is out performing my V-Class.
I did have Database Pak 2000 running which I have just turned off.

Cheers

hi,

Even though N class is a relatively a higher performing system compared to a V-class, the difference in times of the import seems too high. Was the V-class box busy with other processes during the import?? Were there other instances running on the V-box?
Also, what is the model of the internal disks. ARe both using similar scsi connections?

V-Class has nothing else on it.
disk, memory, cpu are not stressed at all.
I was wondering if the Database Pak may have been causing a problem as since I turned it off the import seems to have speeded up

I think the internal buses are faster on a N then a V.

Also what is the speed of the cpu's on the N vs the V. and how many do both of them have?

Without knowing everything about both environments, which would be knowing things like: cpu speeds, disk speeds, what other processes are running, memory, swap, os release levels, tape drive speeds, etc... then it's difficult to make a comparison. The N's backplane speed is FAST, and the RP8400 is even FASTER. Both of these machines are newer than the V-class servers.

Hi there.
We have both machines in our hardware zoo.
The N-class is only available thru remarketing now, if you take it as a UNIX system.
The V-class is only available as V2600, if you need a new one.
The replacement for the N-class is the rp7400 or rp8400.
We do not replace the V-class with a machine like like rpx400, because we need a lot of PCI slots. The V-class has 28 PCI slots available,
the N or the rp only 15 available.
If you need a machine, that is extendible with many PCI slots and will run for the next 8 years, you have only one choice. The V-class will be off support in June 2006. That means, that the support costs will raise skyhigh.
So just take your time for planning and do your analysis very careful.

Is there some official announcement from
HP that support for the v2600 will stop in
June, 2006?
