Extremely slow write speeds to disk : FreeBSD 7.1 and Dell SAS 6/iRAdapter

[Morten P.D. Stevens]

Hi Bradley,

 

FreeBSD is not supported with Dell hardware.

The Dell SAS 6/iR Controller should be a LSI SAS 1068e Controller.

 

Here are the newest available drivers for the LSI_SAS_1068e Controller
(DELL SAS 6/iR)

cs/lsisas1068e/index.html?remote=1&locale=EN

 

There are no drivers for BSD. 

 

Best Regards,

 

Morten

Greetings, 

Please can you assist. 

I have attempted most of the popular BSD Variants such as NetBSD, Open
BSD, FreeBSD... 
The only distrubution that seems to work on the is Dell SAS 6/iR Adapter
is FreeBSD 7.1 
Firmware version & date : 9/29/2008     00.25.47.00 

But the issue is that writing to disk is extremely slow...i.e. 14Mb per
second.... 

If I install any other linux distribution, like CentOS, write speek is
the way it should be..it averages around 190Mb+ per second

I was hoping if it were at all possible for you to assist me in with a
later RAID Controller Driver for the SAS 6/iR Adapter

This is on a Dell PowerEdge R300 Server. 
BIOS Version 1.3.0 
Running Raid 1 

 

Kind Regards, 

Bradley
