You have the PERC3/DC /SC or the DCL version. The DC is dual channel, SC
single channel and DCL without battery cache.
The DCL is fine if you use write through caching instead of write back.
This is not as fast but I am pretty sure it won't toast your server.
I don't know yet if Dell sells the PERC4/SC or /DC yet. These are a lot
faster then the 3 versions. Not because they support the u320 bus but
rather because they are entirely different hardware with respect to the
PERC2 and PERC3 megaraid cards. And they still use the same megaraid driver
which is nice.

I faced different problems in the 2450 then which was a Perc2/Si. But we
replaced them with a Perc2/DC after 3 months service or so and the machines
are still humming without problems.

Perc4 for performance or a Perc3/DC which is older but still works.

well, the dell.nl site lists the following add-on prices with a PE600-scsi
32MB PERC 3/SC RAID Controller (channels: 1xINT, 0xEXT) (+335.00 EUR)
PERC 4/SC RAID Controller (32MB) (channels: 1xINT, 0xEXT) (+200.00 EUR)
However, the plot thickens
with a pe1600sc
32MB PERC 3/SC RAID Controller (channels: 1xINT, 0xEXT) (+480.00 EUR)
PERC 4/SC RAID Controller (32MB) (channels: 1xINT, 0xEXT) (+345.00 EUR)
No word on battery cache backup on the cards but this should give you an
These prices vary per country, server etc.

It might just be your lucky day, if you only knew.
